1 General Information

1.1 Introduction

Spectracom Corporation is a leading manufacturer of synchronized, precise time-keeping devices meeting the demands for accuracy, reliability and trace ability in mission-critical systems across networks. Our NetClock is a direct response to customer needs for cutting-edge synchronization technology at an affordable price.

The Model 9189 is called an NTP time server as it provides disciplined timing using NTP

(Network Time Protocol), and is also called a Master Clock as it meets or exceeds the NENA

(National Emergency Numbers Association) Master Clock standard.

Spectracom NetClock Master Clocks are based on GPS (Global Positioning System) technology

– tracking up to twelve satellites simultaneously and synchronized to their atomic clocks. This enables computer networks to synchronize all elements of network hardware and software

(including system logs) down to the millisecond over LANs or WANs – anywhere on the planet.

Technology advancements, including an embedded processor, make it possible to obtain Legally

Traceable Time

®

tags on log files and simplify digital forensics. The NetClock allows users to accurately time stamp video surveillance systems, access points, card readers, time clocks and alarm systems to provide necessary evidence and validation of events.

Set-up and reporting are web-enabled – a NetClock can be accessed, under appropriate security policies, anywhere within a network. The product features browser-based remote diagnostics, configuration and control as well as Flash memory for remote software upgrades. A 10/100

Mbps Ethernet LAN port provides support for Network Time Protocol (NTP) over a variety of platforms including Windows 2003, 2000 and XP, Win 95/98/ME, NT, Cisco, UNIX, Linux and more. Remote control and monitoring can also be done through SNMP and Telnet.

Time code outputs are available to meet the requirements of diverse systems – RS-232 serial ports, RS-485 data bus ports. Alarm outputs and programmable timer outputs are also provided.

The NetClock Master Clock system includes a CE/UL-approved power supply for international use, GPS antenna and associated mounting hardware.

320 connector. The power adapter is shipped with a line cord compatible with AC receptacles

(NEMA 5-15R) commonly found in the United States and Canada. Alternate type line cords or adapters may be obtained locally.

The chassis ground stud allows the NetClock chassis to be connected to an earth ground or single point ground. Connecting the chassis to a single point ground system may be required in some installations to ensure optimum lightning protection. An earth ground is also recommended in installations where excessive noise on the power line degrades receiver performance.

Rack-mount ears are provided in the ancillary kit if the NetClock will be installed in a standard

19 inch rack.

Note: Auto Negotiate, which determines the network settings to use, only occurs at power-on.

Always connect the Ethernet cable before powering-on the unit for the first time. If the Ethernet cable is connected after power-on, the unit will default to 10 Mbps and half duplex.

Model 9189 Instruction Manual Page 2-3

2.4 GPS Antenna Installation

2.4.1 Antenna Cable for Outdoor Antenna

When using the Model 8225 GPS outdoor antenna, Spectracom recommends using LMR-400 low loss type cable, Spectracom CAL7xxx for the GPS antenna cable. RG-213 type coax, such as Belden 8267, may also be used but low loss cable offers the best performance. To simplify the installation process, Spectracom offers GPS cable assemblies terminated with Type N Male connectors. Specify part number CAL7xxx, where xxx equals the length in feet. Standard lengths are 10, 25, 50, 100, 150 and 200 feet.

If the antenna cable is purchased locally, select coax suitable for outdoor use. Consider the cable's weather ability, temperature range, UV resistance, and attenuation characteristics.

Do not allow the antenna cable to be placed in standing water, as water may permeate through the coax jacket over time. On flat roof installations, the coax can be suspended by cable hangers or placed in sealed PVC conduit. Apply a weather proofing sealant or tape over all outdoor connections.

Installation of a surge protection device in the antenna line is recommended to protect the

NetClock receiver and connected devices from lightning damage. Spectracom offers the Model

8226 Impulse Suppressor to shunt potentially damaging voltages on the antenna coax to ground.

Refer to the Model 8226 Impulse Suppressor Section for a complete description of the Model

8226.

Using Spectracom CAL7xxx or Times Microwave LMR-400 coax, the maximum antenna cable length permitted is 200 feet because the 9189 series allows 12 dB loss. An amplifier is needed whenever antenna cable lengths exceed 200 feet. Installations requiring longer antenna cables may use the Model 8227 Inline Amplifier, or lower loss cable. Refer to the Model 8227 Section for additional information on the Model 8227.

When selecting alternate antenna cable sources, the attenuation characteristics at the GPS frequency of 1575.42 MHz must be known. To ensure optimum receiver performance, the total antenna cable attenuation must not exceed 12 dB. Cable attenuation of greater than 12 dB requires the use of a Model 8227 Inline Amplifier. Refer to Figure 2-1: Cabling recommendations for recommended cable lengths and location recommendations.

2.4.3 Model 8224 GPS splitter

The GPS Antenna Splitter, Model 8224 is designed for use with an existing antenna/cable setup.

It eliminates the need and expense for a second antenna/cable run when two synchronization systems are desirable. The Model 8224 should be installed indoors.

2.4.4 Model 8226 Impulse Suppressor

Spectracom recommends the use of an inline coaxial protector for all products with an outside antenna. Spectracom offers the Model 8226, Impulse Suppressor, to protect the receiver from damaging voltages occurring on the antenna coax. Voltages exceeding the impulse suppresser trip point are shunted to the system ground. The Model 8226 is designed to withstand multiple surges.

Two LMR-400 field-installable N type connectors are provided with the Model 8226 to splice in the Model 8226 wherever it needs to be placed. However, the recommended method to avoid having to cut the antenna cable is to determine the desired location of the Model 8226 ahead of time and then order two lengths of pre-terminated cables instead of just one long cable that spans the entire distance between the antenna and the Master Clock.

Mount the suppressor indoors, preferably where the coax enters the building. Install the suppressor on a grounding panel or bulkhead as shown in Figure 2-2.

Spectracom offers a grounding kit that includes grounding cable, clamps, mounting bracket and ground plane. The Spectracom Part Number for this kit is 8226-0002-0600. Contact our Sales department for additional information.

2.4.5 Model 8227 GPS Inline Amplifier

An inline amplifier is required whenever GPS antenna cable lengths cause greater than 12 dB attenuation. Using Spectracom CAL7xxx coax, an amplifier is needed whenever antenna cable lengths exceed 200 feet.

The Model 8227 GPS Inline Amplifier, shown in Figure 2-3, extends the maximum cable length to 600 feet. The Model 8227 provides 20 dB of gain and is powered by the NetClock receiver.

Figure 2-3: Model 8227 Inline Amplifier

Two LMR-400 field-installable N type connectors are provided with the Model 8227 to splice in the amplifier wherever it needs to be placed. However, the recommended method to avoid having to cut the antenna cable is to determine the desired location of the Model 8227 ahead of time and then order two lengths of pre-terminated cables instead of just one long cable that spans the entire distance between the antenna and the Master Clock.

A five foot N type connector cable is also supplied with the Model 8227 to allow it to be installed after the Model 8226 surge suppressor. The Model 8227 should always be installed after the surge suppressor to prevent lightning or surge damage to the preamp.

Refer to the Model 8227 Manual for proper installation.

2.6 Remote port and Serial comm port output pin-outs and wiring

This section contains wiring and pin-out information for the rear panel Remote RS-485 ports and

Serial RS-232 comm port(s). To verify operation of a Serial port, refer to Section 5-3.

2.6.1 Serial Comm port

The rear panel of the Model 9189 NetClock has one SERIAL COMM port with an optional second SERIAL COMM port (Option 2) available at the time purchase of the unit (Option 2 must be installed at time of initial equipment purchase). These ports can provide RS-232 output data to synchronize external devices that can accept RS-232 Data Formats as an input. The available Data Formats are available are listed in Section 6: Serial Data Formats.

The Serial port(s) can provide RS-232 data in one of two modes. The Interrogation mode provides a one-time RS-232 time stamp each time that the port receives a request character from the external device. In between the requests for time, there is no output. The Multicast mode broadcasts the time stamp every second. The interrogation mode is the factory default. This mode should be changed to multicast mode in the web browser user interface if the external device being synchronized does not send a request character for the time but rather just “listens” for the time to be sent every second.

The configuration of the data, including the baud rate, the Data Format, the request character in the Interrogation mode, Time Zone Offsets and Daylight Saving Time rules is chosen from the web browser user interface. Refer to Section 3, Interface setup for more information. The

SERIAL COMM ports have a standard RS-232 pin configuration as shown in Figure 2-4 and

Table 2-2.

3.2 Login

The default mode for the web browser user interface is Read only. Any user can view the unit’s configuration and status logs without the ability to make changes to the configuration. There are two available login modes that require the user to know a login password:

1. Configuration Mode allows non-critical system changes.

2. Administrator Mode allows full control over all parameters. This mode should only be used by advanced users. Changes made while in this mode may be detrimental to the proper operation of the NetClock.

Note: Only one user is allowed into the web browser user interface at a time. If you try to access the web browser user interface with someone else already in the browser, a screen will display the IP address of the computer that is currently accessing the browser.

Refer to Figure 3-2 for a sample list of the login permission requirements. This list is also displayed on the web browser user interface screen under the login mode buttons.

Note: For security reasons, the Admin and config login lasts for 15 minutes or until the NetClock is rebooted (Whichever occurs first). For security reasons, you will be exited out of the login after 15 minutes as the connections reset every 15 minutes.

Model 9189 Instruction Manual Page 3-7

Figure 3-2: Log-in Permissions

CAUTION:

The Administrator login provides the most power to change settings but an erroneous entry could cause the NetClock to malfunction or not perform within specifications.

Only technicians trained in NetClock operations should be given access to the Administrator mode.

Chose the “administrator mode” to login as admin mode or chose “configuration mode” to login as the config mode. Figure 3-3 and Figure 3-4 display the appropriate login screen for the desired login mode. Type the password for the mode selected. Note that the password is capitalletter sensitive.

Page 3-8 Model 9189 Instruction Manual

Figure 3-3: Configuration mode Log-in

Figure 3-4: Administrator mode Log-in

No Password?

That’s OK; you can still view the unit’s configuration settings in the read-only mode.

Model 9189 Instruction Manual Page 3-9

Default Passwords

The default access passwords for the Configuration and Administrator Modes are:

Username: config Username: admin

For security reasons, we recommend you change the passwords and don’t lose them! If the passwords are written down, they should be stored in a secure location such as a safe for later retrieval by authorized personnel.

Once you have access to the settings web pages, you can set up each page.

3.2.1 To Change the Default Login Password Values

For security reasons, the account passwords cannot be changed using either the web browser user interface or telnet command. Password changes must be made using the RS-

232 Serial Setup Interface connection on the rear panel. To change the account passwords, connect to the Serial Setup Interface with a straight-thru serial cable. Using

HyperTerminal, Procomm or any other terminal emulator, login as admin using the current password. At the command prompt, type the following:

To change the admin password, type:

sec password admin <enter>

To change the config password, type:

sec password config <enter>

The unit will then ask you to type in the old password and then to type the new password (twice).

Example:

Type: sec password <enter>

Response: Account:

Type: [current account name] <enter>

Type: [current password for this account] <enter>

Type: [New password for this account] <enter>

Response: New Password (again):

Type: [New password for this account] <enter>

Response: New Password set

For additional information on the sec command, refer to the software command appendix (sec command).

Page 3-10 Model 9189 Instruction Manual

NOTE: Always LOGOUT and EXIT CONNECTION TO THE PRODUCT prior to closing the web browser user interface when you are finished viewing the NetClock settings. For security reasons, only one connection session is supported at any one time, so this ensures that a new session can be activated immediately. If you don’t log out or exit the connection, you will have to wait a time-out period or reset the unit to begin a new session.

3.2.2 To reset the current Login Password Values back to the factory default values

Once the config and admin passwords have been changed from their default factory values, the passwords can always be changed again in the future to new desired values as long as the current passwords are still known (Refer to Section 3.1.4). However, the changed passwords may not be known by the current user so the procedure to change the passwords described in section 3.1.4 will not be available.

If the current admin level password is unknown, both of the config and admin level passwords can be reset to the factory defaults and then changed to the desired passwords. Perform the following to reset the passwords back to the factory defaults to allow the passwords to be edited.

1) Connect to the Serial Setup Interface with a standard straight-thru serial cable and a PC running HyperTerminal or Procomm (As described in Section 3-1).

2) With “Spectracom Login:” displayed, type defaults <enter> (If the login prompt is not displayed, hit the enter key).

3) When the NetClock prompts for “Password:”, just hit the enter key (Don’t enter a password).

4) The unit will respond with “passwords reset”. The admin password is now set back to the value of admin123 and the config password is now set back to the value of config12.

5) Using these current password values, follow the procedure in Section 3.2.1 to change these passwords to the desired values.

Model 9189 Instruction Manual Page 3-11

3.3 Alarms

The operational status of the NetClock can be monitored via the condition of its alarms. The alarm states may be obtained using any of the following mechanisms:

Timer/Alarm Relays output connector

. This is a

Power Failure: The NetClock has lost power. This is both a Major and Minor alarm.

Antenna Problem: The antenna sense circuitry warns when the antenna is not connected or a cable short or open is detected. This is a Minor alarm.

Page 3-12 Model 9189 Instruction Manual

An alarm is asserted whenever any of the following conditions exist AND the alarm has been enabled on the alarm setup screen via a web browser user interface:

User-defined Alarm: The user-specified period of time allotted for operation while tracking less than a user-specified number of satellites has expired.

This can be a Major and/or Minor alarm.

Software Fault: One or more software sub-systems has experienced a major runtime error. This is a Major alarm.

Figure 3-5: Alarm Setup Screen

User-defined alarms are configured using the Alarm Setup screen (Figure 3-5) from a web browser user interface. The Alarm Setup screen may be viewed by clicking “System Setup” along the bottom of the main browser screen, followed by clicking “Alarm” on the left side of the screen. The default is a major alarm for tracking less than 1 satellite for 5 seconds.

NOTE: The Alarm Setup screen will not allow modification of any of the fields unless you have logged into the system in either configuration mode or administration mode.

Clicking the check box to the left of a particular user-defined alarm will enable that alarm condition. Each alarm condition may be set to exist for a specified duration before activating the alarm. This is done by filling in the Timeout fields directly beneath the alarm condition.

3.4.1 Configuring the Event Time

The web browser user interface allows for the configuration of 128 events that can turn any one of the event timer relays on or off. Make sure the rear panel relay that is going to be associated with an event is configured to be the event timer relay in order to use this feature (see Section

3.4.1 for details on relay configuration).

To configure the events:

Connect to the web browser user interface. Login to configuration mode (or administration mode).

Along the bottom of the interface select Relay Setup.

Along the left hand side select Event Timer Relay.

Page 3-14

Figure 3-6: Event Timer Relay Screen

Model 9189 Instruction Manual

A new page will load. This is where the user specifies which event to edit/view. If any events are already configured, they will be displayed by event number on this page. There are no requirements on the order of the events; each one is completely independent of the others. Enter the number of the event that you wish to edit/view and click the Edit/View button.

Now a page that displays the settings of the selected event appears and if logged in to configuration mode (or administration mode) the settings can be changed.

Choose a Time Zone

On the left side pane, select “Set Event Clock”. Choose an already defined Clock (Time Zone) or define a new one. See Section 3.7 for more details on Local System Clock settings.

Model 9189 Instruction Manual Page 3-17

3.5.1 How to set up the GPS receiver

Using the web browser user interface, you will find the GPS configuration web page under the

System Set up category. The GPS configuration web browser user interface page is designed to allow a user to configure the GPS receiver to provide more accurate results and faster start up, but you do not have to configure them for the unit to run properly.

ANTENNA CABLE DELAY:

Figure 3-8: GPS Set-up Screen

To set this value, you must be logged into the unit with the Configuration or Administrator

Mode. By setting the correct antenna cable delay, the on-time point is offset by the delay value to compensate for the antenna and in-line amplifier delays. Under typical condition, the expected cable and amplifier delays are negligible. You can calculate the delay based upon the manufacture’s specification.

Page 3-18 Model 9189 Instruction Manual

The range of the cable delay is from 0 to 999999 nanoseconds, the default value is 0 nanosecond, and the resolution is 1 nanosecond.

The following formula is used to calculate the cable delay:

D = (L * C) / V

Where:

D = Cable delay in nanoseconds

L = Cable length in feet

C = Constant derived from velocity of light: 1.016

V = Nominal velocity of propagation expressed as decimal, i.e. %66 = 0.66 Value is provided by cable manufacturer.

Note: The antenna cable is delay is nominal and beyond the accuracy of the GPS receiver. The antenna cable delay does not normally need to be set.

LOCATION OF THE UNIT:

You can read the current location of the unit calculated by the GPS receiver without logging in.

The GPS receiver will automatically update this field when it has a Position Fix. Check the GPS

Signal Status web browser user interface page, and if the status is “Position Fix”, then the location shown on this page is the right location.

You can only write the new location value to the unit when logged in under the Configuration or

Administrator mode. The location input by the user may only help to speed up the time to first fix during the initial installation. The unit will automatically check the status of the GPS receiver after receiving the location input from the user, then based on the status of the GPS receiver, the unit will either tell the user that the GPS receiver already has finished the first fix and the input was abandoned, or send the location to the GPS receiver.

3.5.2 Set System Mode

The system supports two modes known as single satellite mode and standard mode (factory default).

Use the single satellite mode if you are using a window-mount antenna and cannot get at least four satellites on a continuous basis (Window-mount antennas typically can’t track at least four satellites at all times). This will switch the GPS qualification algorithm used, and allow the system to operate with a fewer number of satellites, but the accuracies of the timing will be decreased because of the poor GPS antenna visibility.

Note: Single Satellite mode compromises the accuracy of the NetClock. Always use standard mode if you are using a roof mount antenna and can get at least four satellites. This is the factory default.

Model 9189 Instruction Manual Page 3-19

To set the System Mode using the web browser user interface:

1. Using a PC with a web browser connect to the product by typing in the product’s IP address into the address window of the browser as follows: http://10.10.200.1 (or your product’s IP address).

2. Press the “Enter Main Page” button.

3. Select the login link on the top right corner to login as administrator.

4. On the lower menu line select the “System Setup” item.

5. On the left side menu select the “Set System Mode” item.

The setup window for system mode is then displayed in the center of the screen.

Figure 3-9: Set System mode screen

Page 3-20 Model 9189 Instruction Manual

3.6 GPS Signal Status

HOW TO READ THE GPS SIGNAL STATUS:

The GPS Signal Status pages provide insight into the GPS receiver’s operation and the signal quality from the satellites. This information is useful to verify proper antenna placement and receiver performance during installation and later troubleshooting.

The overall tracking status, position solution and a table containing individual satellite data is on this page.

Figure 3-10: GPS Signal Status Setup Screen

Model 9189 Instruction Manual Page 3-21

Tracking X satellites:

Where: X = Number of satellites currently tracking (0 – 12)

GPS Status = SSSS

Where: SSSS = Receiver Status

Acquiring satellites is possible if the GPS Receiver is still looking for qualified satellites.

Bad Geometry is possible if the GPS Receiver is tracking qualified satellites, but the number of satellites or their relative position is not sufficient for calculating position.

2D Fix is possible if the receiver is tracking at least three qualified satellites.

3D Fix is possible if the receiver is tracking at least four qualified satellites.

Position Hold is possible if the GPS receiver has collected enough information to determine the location of the GPS receiver.

DOP = ##.#

Where: DOP means dilution of precision. The range is from 00.0 to 99.9

This value indicates the degree of uncertainty of a Position Fix due to the geometry of the

Satellites used in the solution. The lower the DOP value, except 0, the lower the degree of uncertainty.

Antenna Sense = SSSSS

Where: SSSSS reports the status of the antenna sense circuit. There are three main flags (OK,

Over Current, and Under Current). The three flags are described below:

OK Flag

The OK flag is displayed if both antenna sense bits are cleared. This indicates that the antenna is drawing current within the normal range.

Over Current Flag

This flag is displayed if the over current bit is set. This indicates that too much current is being drawn through the circuit and the overload protection circuit is limiting the feed current. The receiver will attempt to continue the normal acquisition and tracking process regardless of the antenna status.

Under Current Flag

This flag is displayed if the undercurrent bit is set. This indicates that little or no current is being drawn through the circuit, which may be due to a disconnected antenna, a severed antenna cable or a damaged antenna. The receiver will attempt to continue the normal acquisition and tracking process regardless of the antenna status.

Undercurrent indication < 8 mA

Overcurrent indication > 80 mA

Page 3-22 Model 9189 Instruction Manual

Note: This condition will also be present if a GPS antenna splitter that does not contain a load to simulate an antenna being present is being used.

Latitude = [N:S][DD MM SS.SSSS]

Longitude = [E:W][DDD MM SS.SSSS]

Where: N = North latitude

S = South Latitude

E = East Longitude

W = West Longitude

D = Degree

M = Minute

S = Second

Quality = QQQQQ

Where: QQQQQ = Result of GPS qualification, either PASSED or FAILED. The GPS signal is considered qualified when at least one satellite is received having a vehicle ID of at least 4 that are available for Position Fix Usage while in the normal mode of operation (Or at least 1 satellite that is available for position fix when the unit is single satellite mode).

Information on each satellite the receiver is currently tracking is presented in table form. The table columns are described below:

CHANNEL = Channel Number of the GPS receiver, 1…12

VID = Vehicle (satellite) Identification Number, 1…37

MODE = Channel Tracking Mode,

Where:

0 = Code Search

1 =

2 =

Bit Sync Detect

Message Sync Detect

6 = Satellite Time Available

7 = Ephemeris Acquire

8 = Avail for position

Note: Mode 8 is the normal state for a valid satellite in use

Model 9189 Instruction Manual Page 3-23

STRENGTH = Signal strength value relative to the Signal to Noise Ratio [SNR]. Range:

0…255, the higher the number, the greater the receiver signal.

STATUS = Channel status flag. Convert the hexadecimal code word to binary to find the status flag set.

3.7.1 Time Zone and DST

How to set up Time Zone and DST Rule:

The unit will allow you to define different Time Zone and DST rules for different Interfaces and a front panel display (Option 2 if so equipped). In order to use this feature properly, users have to know the correct Time Zone Offset and DST rule for your area.

The general Time Zone and DST rule information can be found from the following web sites: http://www.worldtimeserver.com/ , http://webexhibits.org/daylightsaving/b.html

.

Since the Time Zone and DST rules are set up for each Interface and front panel display separately, you should click the “Interface setup” hyperlink, and then select the Interface you want to modify. Then you will see the Time Zone setup and DST setup option on the web browser user interface page.

Model 9189 Instruction Manual Page 3-29

Time Zone

Under the “TIME ZONE SETUP”, you will see two choices:

• Automatically configure to unit’s physical locality

• Manually defined UTC offset

Auto Time Zone

By selecting this option, the unit will compute the Time Zone Offset automatically based on the location of the unit provided by GPS receiver.

If you select this feature before the GPS receiver completes the position calculation, a message will be displayed to explain that this feature is not valid until the position is available.

If you select this feature after the GPS receiver determines its position, the computed Time Zone

Offset information will be shown.

Note: Automatic Time Zone calculations are imprecise because the Time Zones are determined by local political boundaries and may change often. This feature is made available as an aid only.

To apply the computed Time Zone, select the check box for the desired Interface.

Manual Time Zone

A drop down box is provided for the choice. Left click the drop down box and select the time zone offset you want to use.

Note: All of the Time Zone Offset drop-downs in the web browser user interface are configured as UTC plus or minus a set number of hours. For Eastern, chose UTC–5, for Central, chose

UTC-6, for Mountain, chose UTC-7 and for Pacific, chose UTC-8.

DST rule

Under the “DST SETUP”, you will see four radio buttons. , The four options are “No DST rule, always standard time”; “Manually defined by region”; “Manually defined by week and day”;

“Manually defined by month and day”.

No DST Rule, always standard time

This option should only be used when you do not want to apply any DST rule to this Interface output.

Page 3-30 Model 9189 Instruction Manual

Auto DST

This feature is designed to compute the DST rule automatically based on the location of the unit provided by GPS receiver.

If you select this feature before the GPS receiver completes the position calculation, a message will be displayed to explain that this feature is not valid until the position is available.

If you select this feature after the GPS receiver determines its position, the computed DST rule information will be shown.

Note: Automatic DST calculations are imprecise because the rules for DST are determined by local political boundaries and may change often. This feature is made available as an aid only.

To apply the computed DST rule, select the check box for the desired Interface.

Manually defined by region

This option is recommended if you do not need to define a special rule. Under this option, there is one drop down box. Left click the drop down box and you will see four regional choices:

“Europe”, “North America”, “Australia-1” and Australia-2”.

The official DST rules for these four regions are as follows:

Europe

Start: Last Sunday in March at 1am UTC

End : Last Sunday in October at 1am UTC

North America

Start: First Sunday in April at 2am local time

End : Last Sunday in October at 2am local time

Australia-1

Start: Last Sunday in October at 2am local time

End : Last Sunday in March at 3am local time

Australia-2

Start: First Sunday in October at 2am local time

End : Last Sunday in March at 3am local time

Manually defined by week and day

This option is provided for advanced users. You can input start time, end time and the hour to change for the daylight saving. By selecting this option, the DST rule can be defined based on the weekday, week, and month of the local time you defined for this Interface.

Model 9189 Instruction Manual Page 3-31

Manually defined by month and day

This option is provided for advanced users. You can input start time, end time and the hour to change for the daylight saving. By selecting this option, the DST rule could be defined based on the day and month of the local time defined for this Interface. If you select the February 29th as the start time or end time, the unit will respond that the entry is an illegal date.

Page 3-32 Model 9189 Instruction Manual

This section contains information on configuring the Remote and Serial outputs.

3.8.1 Configuration parameters for the Remote and Serial Interfaces

The Model 9189 has either one (standard configuration) or two (with Option 2 installed) RS-232 ports (also called Serial Ports) and two RS-485 ports (also called Remote Output Ports) that support independent output of date/time stamps. The web browser user interface is the method by which these can be configured, and the available options are described below:

Baud Rate:

This is the speed at which this Interface will output data. Supported values are 1200, 2400,

4800, and 9600. 9600 baud is the default.

Data Format:

This is the Data Format in which date/time stamps are outputted. Available Formats are 00, 01,

02, 03, 04, 07, 08 and 90; and are described in detail in the "Data Format" section above. Format

00 is the default.

Note: Because Data Format 2 is ALWAYS a UTC output, it cannot have a Time Zone Offset or

Daylight Saving Time rule enabled. Conversion to Local Time is accomplished by the device receiving Data Format 2. An error message will be generated if a Time Zone Offset or DST rule is attempted when selected to Data Format 2.

Request Char (feature not available on RS-485 port):

If Multicast is selected, the unit will automatically broadcast once-per-second. If User Defined is selected, the unit will only send data upon reception of the character in the textbox. The default is the user-defined character 'T'. Multicast should be selected if the external device does not send a request character because it wants to receive the data every second instead.

System Clock:

This field allows the user to select which Local System Clock (Time Zone) to use when sending data. The default is UTC. See Section 3.8 for more information on how to set these.

3.8.2 To configure a product's Interface via web browser user interface

Connect to the web browser user interface after booting the unit. Login to either configuration- or administrator-level mode if changes are desired. Choose "Interface Setup" from the bottom frame, and the desired port from the left frame. Serial Ports correspond to RS-232 outputs and

Remote Output Ports correspond to RS-485 outputs. All fields will display the current system settings. At the bottom of the frame, clicking Reset will revert any changes made at this window since last pressing Submit.

Model 9189 Instruction Manual Page 3-33

Note: The times indicated in all log entries are UTC (No correction for Local time or Daylight

Saving Time).

3.9.1 Display Alarm Log

To Display the Alarm log do the following:

Use a PC with a web browser and connect to the product by typing in the IP address into the address window of the browser as follows: http://10.10.200.1 (or your IP address).

Press the "Enter Main Page" button. On the lower menu line, select the "Status & Log" item.

On the left side menu, select the "Alarm Log" item. The Alarm History Log is then displayed in the center of the screen. Each time a change in alarm status occurs an alarm log is created. An alarm log includes the UTC time and date of the log, the alarm relay status and lists the conditions causing the alarms. The alarm log is displayed one page at a time, and can be navigated by using the scroll bar control on the right hand side.

Example response:

TIME= 10:17:19 DATE= 2000-03-21 STATUS CHANGE

ALARM RELAY= OFF

ACTIVE ALARMS: NONE

TIME= 13:51:29 DATE= 2000-05-05 STATUS CHANGE

ALARM RELAY= ON

ACTIVE ALARMS: MAJOR

Time Sync Alarm

TIME= 18:24:44 DATE= 2000-05-05 STATUS CHANGE

ALARM RELAY= OFF

ACTIVE ALARMS: NONE

In the example above, the antenna cable was damaged at 13:51:29 on May 5, 2000. Note that a

Minor Alarm was asserted at that time due to an "Antenna Problem". Since no GPS signal could be received, the Sync Time-out counter expired, causing a Major Alarm due to loss of time sync.

The cable was repaired at 18:23:39, clearing the Minor alarm and Antenna Problem alarm messages. The receiver then reacquired and qualified at least one satellite for one minute, which cleared all alarms at 18:24:44.

Page 3-36 Model 9189 Instruction Manual

3.9.2 Display Dial-Out Log (Option 3 – Modem)

Note: This log is only available if Option 3, Modem is enabled.

If the NetClock has the optional Dial-Out Modem Interface (Option 3), display the log by doing the following:

Use a PC with a web browser and connect to the product by typing in the IP address into the address window of the browser as follows: http://10.10.200.1 (or your IP address).

Press the "Enter Main Page" button. On the lower menu line, select the "Status & Log" item.

On the left side menu, select the "Dial out Log" item. The Dial out History Log is then displayed in the center of the screen. Each time an operation in the dial out process occurs, a dial out log entry is created. A dial out log includes the UTC time and date of the log, the operation that was just completed or the status from the previous operation. The log can be navigated by using the scroll bar control on the right hand side.

Example response:

TIME= 18:00:51 DATE= 2005-07-07

Modem dial out to 9 1-303-494-4774.

TIME= 18:02:04 DATE= 2005-07-07

Dial out successful.

TIME= 18:02:06 DATE= 2005-07-07

Time Sync Success: Subsecond counter adjusted by -1.3209 ms.

TIME= 18:02:07 DATE= 2005-07-07

Time Sync Success: Sys Clock adjusted by 0 sec.

TIME= 18:02:07 DATE= 2005-07-07

No leap second detected this month

In the example above, the unit initiated a dial out at 18:00:51 to the number (9)1-303-494-4774.

At 18:02:04 it successfully finished the call and disconnected the modem from the phone line. It then processed the collected time messages and adjusted the unit’s PPS back by 1.3209ms. It then adjusted the system clock by 0 seconds at 18:02:07. In that same second it verified that there was no leap second for that month

During the dial out operation, errors and timeouts can occur. These are also logged in the Dialout log. The exception log entries (in alphabetical order) are as follows:

Calibration initiated:

Calibration routine has started.

Calibration call success (#/#) calls made: Gives # of calls that have been successful and # of calls that are scheduled.

Model 9189 Instruction Manual Page 3-37

Calibration call failed: failure # of #: Gives # of calls that have failed in a row and # before calibration will fail.

Calibration failed:

Calibration has ended without setting the latency value.

Calibration Success - Latency set to # ns: Calibration was successful. The latency was set.

Counter resolution means this number will always end with 00.

Call failed: [reason]:

Possible reasons are:

State Change – Modem no longer needs to synchronize system (example: GPS

Busy Signal – Time source was busy.

Modem Error – Unspecified modem error

No carrier – No modem picked up on other end, phone # may be wrong

No dial tone – Could not get a dial tone

Netshow Request – “net show” was typed on the console port

Port Change – Switched to console mode

No Sync Message – Could not synchronize with the remote modem

Dial out successful:

Messages were successfully collected from time source.

Failed to sync during call:

This log entry records a dial out attempt that was successful in communicating with the modem time reference, but was unable to sync the time messages during the call.

Leap Second check failed [reason]:

Only reason is BAD MESSAGE, which means that the leap second bit was not consistent across all messages. This can happen if the month rolls over during a call or if some of the message characters are lost.

Leap second detected: Leap second will be [ADDED/DELETED] at the end of the month

Leap second is to occur this month.

Modem Response Failure:

Failed to get a response from the modem at initialization.

Modem Call Failure:

Failed all call retries.

Modem dial out to #:

Gives the phone number which was dialed.

Page 3-38 Model 9189 Instruction Manual

No leap second detected this month:

Whenever a successful call is made and there is no leap second.

Test Call Failure:

The test call failed at some point. The reason for failure should be evident from the other messages.

Test Call Success:

The most recent test call successfully got messages from the dialed number.

Timeout occurs, operation is aborted:

During time message acquisition and 1PPS sync process, if the process takes too long, it will be automatically aborted and retried if possible. For example, if a time message acquisition receives no response from the modem for two minutes, the operation is aborted. If there are retries remaining, the dial out process is restarted.

Time Sync Failure: [reason]:

The modem failed to set the time. Gives the reason why the time could not be set. Possible reasons are:

Port Switched – The port was set to console mode.

Alternate Sync – The unit got sync from another source first.

Timeout – The unit timed out while trying to reset time.

Unknown Error – ?

Time Sync Failure: Sys Clock not adjusted [reason]:

The sys clock could not be adjusted. Gives the reason why the clock could not be adjusted.

Possible reasons are:

Bad Timing - The unit could not verify the timestamps. This is a rare condition and does not indicate any hardware error unless it happens frequently.

PPS error - The unit could not get a good PPS signal from itself.

Time Sync Success: Subsecond counter adjusted by # ms:

Time was successfully adjusted.

Time Sync Success: Sys Clock adjusted by # sec:

System clock (date and time) was adjusted.

Time verification success: Time within normal parameters:

While in holdover, time was verified and is still within 0.5 seconds. This implies that a leap second was not missed.

Time verification: Time too far off. Exiting Sync:

Time is off by more than 0.5 seconds. A leap second was missed or something is very wrong.

Page 3-40 Model 9189 Instruction Manual

3.9.4 GPS Qualification Log

The GPS Qualification Log records the number of qualified satellites tracked each second. At the end of every hour a log entry is created and the counters start again. The GPS qualification log is useful in verifying receiver and antenna performance.

The GPS qualification log is outputted in the following format:

TIME= HH:MM:SS DATE= YYYY-MM-DD

N = XXXX

N = XXXX …

Q = QQQQ

Where:

HH:MM:SS= UTC time log was created

YYYY-MM-DD= Date log was created

N= The quantity of satellites

XXXX= Number of seconds the receiver tracked the listed quantity of satellites since the beginning of the hour, 1…3600.

QQQQ= Number of seconds since the beginning of the hour the GPS signal was qualified,

0…3600

Typically, the receiver tracks two to three satellites when using a Model 8228 Window Mount

GPS antenna. When using the Model 8225 Outdoor antenna, the receiver will typically track five or more satellites.

There may occasionally be short periods when the receiver is unable to track any satellites. When this occurs, the Time Sync alarm count down timer is started. The Sync Alarm Timer resets whenever the receiver reacquires and qualifies at least one satellite for one minute. If a receiver is unable to receive and qualify any satellites within the sync alarm period (two hours), a Time

Sync Alarm is asserted.

Satellites are qualified as valid when the received vehicle ID number is greater than 1 and the satellite is available for Position Fix usage. The qualification count “Q” is incremented for each second these conditions are met. Typically, the Q value for each hour should exceed 3000.

To view the GPS Qualification Log, do the following:

1. Use a PC with a web browser and connect to the product by typing in the IP address into the address window of the browser as follows: http:// 10.10.200.1 (or your IP address).

2. Press the "Enter Main Page" button.

3. On the lower menu line, select the "Status & Log" item.

GPS Receiver = 12 Channel M12+ Version #:

This statement is printed after each power cycle to give the version of the GPS receiver.

First Satellite Acquired:

This log time stamps when the receiver acquires a satellite for the first time.

For example: First Satellite Acquired 19:21:34 2003-07-29

GPS Signal Qualified:

This log entry records when the receiver acquires or re-acquires and qualifies at least four satellites for one minute. A satellite is considered qualified if the received vehicle ID number is at least 4 and if all four satellites can be used for Position Fix. The time and date contained in the log reflect UTC time. If the unit is operating in the single satellite mode (not recommended), the minimum number of satellites for qualification drops to only 1 satellite required for one minute.

For example:

GPS Signal Qualified 19:32:00 2003-07-29

Clock adjusted by # seconds:

A log entry is made in this log for any system time adjustment larger than 1 second.

Clock time source changed to [source]:

A log entry is made every time the clock’s reference is changed. For example, the unit is synchronized to GPS but someone tries to manually set the time. The log will indicate that the input was “user”.

Clock entering sync:

This entry will be made when the unit acquires time sync

Leap second inserted at end of month:

The reference input had detected that a leap second was to occur at the end of the month and the

NetClock added the necessary correction to account for the leap second.

Leap second removed at end of month:

The reference input had detected that a leap second was to occur at the end of the month and the

NetClock removed the necessary correction to account for the leap second.

GPS SOFTWARE RESET:

This log entry indicates the GPS receiver stopped responding so the unit has performed a software reset of the GPS receiver daughter-board to try to restart the receiver.

GPS HARDWARE RESET:

This log entry indicates the GPS receiver stopped responding so the unit has performed a hardware reset of the GPS receiver daughter-board to try to restart the receiver.

The Operational log is output in a continuous format, and can be navigated by using the scroll bar control on the right hand side.

3.11 NTP/SNTP

NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are client-server protocols for synchronizing the time on IP networks. NTP provides greater accuracy and error checking than SNTP. NTP and SNTP can be used to synchronize the time on any computer equipment that is compatible with the Network Time Protocol. This includes CISCO routers and switches, UNIX machines and Windows machines with a suitable client. To synchronize just one workstation, several freeware or shareware NTP clients are available on the Internet. The software running on the PC determines if NTP or SNTP is used.

The NTP setup page provides full control of the operation of your NTP server. Follow the simple steps below to quickly set up your unit as an NTP server on your network.

Connect to your unit through the web browser user interface.

Click on the System Setup link on the bottom of the screen to open the menu for system configuration.

Model 9189 Instruction Manual

Figure 3-15: NTP Screen

Page 3-45

Click on the NTP link on the left side of the screen to enter the NTP setup page. Note: you must be logged in as an administrator to modify the NTP settings.

The NTP server can operate in unicast mode, multicast mode, or both concurrently.

• To enable unicast operation, place a checkmark in the box labeled “NTP Unicast”.

• To enable multicast operation, place a checkmark in the box labeled “NTP Broadcast

…”.

• To enable both modes, be sure that both boxes have a checkmark.

In unicast mode, the NTP server will “listen” for NTP request messages from NTP clients on the network. When an NTP request packet is received, the NTP server will send an NTP response time packet to the requesting client. Under typical conditions, the Spectracom NTP server can service up to 390 NTP requests per second, without MD5 encryption enabled (read below).

In multicast mode, the NTP server will send out unsolicited NTP time packets to the local broadcast address at a user-specified rate. Enter the desired frequency in seconds into the

Broadcast field on the setup page.

Note: Unicast Mode is the predominant mode of operation when synchronizing a network.

Multicast is reserved for specialized software requirements and is not commonly used.

By default, the NTP server supports authenticated NTP packets via an MD5 authenticator. This feature does not encrypt the time packets, but attaches an authenticator, which consists of a key identifier and an MD5 message digest, to the end of each packet. This can be used to guarantee that NTP packets came from a valid NTP client or server, and that they were not tampered with during transmission.

To use the MD5 authentication in unicast mode, both the NTP client and the Spectracom NTP server must contain the same key ID / key string pair and the client must be set to use one of these MD5 pairs. The key ID must be a number between 1 and 4,294,967,295; the key string may contain any alphanumeric characters and can be from 1 to 16 characters long. Duplicate key

IDs are not permitted.

When operating in unicast mode, the Spectracom NTP server supports a secure mode, which can be enabled by placing a checkmark in the box labeled “Secure Mode”. With this box checked, any NTP requests received by the NTP server, which do not contain a valid “Key ID / Key

String” pair will be ignored and no NTP response packet will be sent.

The following table shows how the Spectracom NTP server will respond to various unicast requests with and without secure mode enabled.

Type of NTP Request Packet

No MD5 authenticator

Without “Secure Mode” checked

Response with no MD5 authenticator

With “Secure Mode” checked

No response

Page 3-46 Model 9189 Instruction Manual

Invalid MD5 authenticator

Valid MD5 authenticator

Response with valid authenticator (using key 0)

Response with valid authenticator (using same key as the request)

No response

Response with valid authenticator (using same key as the request)

When operating in multicast mode, the Spectracom NTP server can be configured to append

MD5 authenticators to each packet. To enable this, check the box labeled “Use MD5 authentication with key …” under the NTP Broadcast setting, and enter the key ID to be used.

The Session statistics checkbox will enable or disable logging of NTP usage statistics. This is displayed as part of the status and log page. Refer to the status and log section for details.

At any time during the setup, press “Submit” to save the settings or “Reset” to restore the settings to their previous state.

Spectracom cannot provide technical assistance for configuring and installing NTP on Unixbased applications. Please refer to http://www.ntp.org/ for NTP information and FAQs. Another good source for support is the Internet newsgroup at news://comp.protocols.time.ntp/ .

Spectracom can provide support for the Windows NT and Windows 2000 time synchronization.

3.11.3 Application Note: MD5 Authentication using a Cisco Router

According to the Cisco Manual located on their website, to configure NTP Authentication, the user would use the following commands: set ntp key public_keynum {trusted | untrusted} [md5 secret_keystring]

where:

public_keynum is a number from 1 to 4,292,945,295 and is a key ID number

“trusted" is used to activate the key, "untrusted" to disable the key md5 means the keyword (the type of key, Cisco only uses md5)

"secret_keystring" is the key value, it is from 1 to 32 printable characters.

To interoperate with the Ethernet NetClock, the "secret_keystring" must be eight printable characters and the public_keynum must be a number from 1 to 6.

For example: to define key id number 3 with the secret_keystring TICKTOCK" would require the following commands into the Cisco Router: set ntp key 3 trusted md5 TICKTOCK

Model 9189 Instruction Manual Page 3-47

This will define the key and enable it in one step. The command "show ntp" can be used to display the key definitions.

On the NetClock side you would enable MD5 authentication with key 3 and then enter

TICKTOCK into the Key Table with ID 3.

Page 3-48 Model 9189 Instruction Manual

The NTP statistics is controlled from the NTP configuration described in the NTP section of this manual. To display the NTP Statistics do the following:

Use a PC with a web browser and connect to the product by typing in the IP address into the address window of the browser as follows: http:// 10.10.200.1 (or your IP address)

Press the "Enter Main Page" button. On the lower menu line, select the "Status & Log" item.

On the left side menu, select the "NTP Statistics" item. The NTP Statistics is then displayed in the center of the screen as shown:

Figure 3-16: NTP Statistics

Model 9189 Instruction Manual Page 3-49

The overall statistics provides a quick overview of all the NTP activities from the unit while the client statistics displays the details of each client’s interaction with the unit. Invalid requests are colored in red to improve the readability of the statistic list. If you need to find a specific client, you can use the find (Ctrl + F) function of the browser and search for the client’s I.P. address.

The statistics log can retain the entries for up to 200 clients. Once the maximum of 200 clients has been reached, sequential clients over 200 will start to overwrite the oldest entries in the log

(this may or may not be in the order listed in the log).

The following are descriptions of the fields contained in the NTP Statistics chart.

Total Clients: The total number of clients that the NetClock has received NTP packets from, up to a maximum of 200.

Requests: Number of NTP packets received by the NetClock from a client or clients.

Processed Requests: Number of NTP packets received that were processed by the NetClock.

The NetClock will only process received NTP packets while NTP is enabled AND NTP Unicast is enabled. These settings can be enabled from the NTP configuration page.

Authenticated Requests: Number of NTP packets received by the NetClock that were processed, included authenticator fields, and authenticated successfully.

Invalid Requests: Number of NTP packets received by the NetClock that were processed and either (1) included authenticator fields but authenticated unsuccessfully, or (2) did not include authenticator fields and Secure Mode was enabled. Secure mode can be enabled or disabled from the NTP configuration page.

Dropped Requests: Number of NTP packets received by the NetClock that were either (1) not processed because NTP was not enabled and/or NTP Unicast was not enabled, (2) ignored because the packet length did not match the valid length for an NTP packet, (3) ignored because the NTP request specified a mode that the NetClock does not support, or (4) ignored because the

NTP request specified a version that the NetClock does not support. NetClock supports requests using CLIENT mode or SYMMETRIC ACTIVE mode. NetClock supports requests using versions 1, 2, 3, or 4.

Request Responses: Number of NTP request packets received by the NetClock that were successfully responded to. A successful response is logged when the NetClock transmits an NTP response packet to the client without noting any errors.

Response Errors: Number of NTP request packets received by the NetClock that were unsuccessfully responded to. An unsuccessful response is logged when the network protocol stack is unable to successfully transmit the response packet to the client.

Time of Last Request: The time at which the last NTP packet was received from a particular client.

Page 3-50 Model 9189 Instruction Manual

Last Request Invalid?: Identifies whether or not the last NTP request received from a particular client was an invalid request.

Note: To clear the NTP Statistics log, login to the administrator mode and press the “reset” radio button.

3.13 Relays

3.13.1 Configuring the relays

The operational status can be monitored remotely using the TIMER/ALARM RELAYS connector on the rear panel. This connector provides the common, NO and NC contacts for three relays. These relays can be connected to an alarm lamp, horn, or other indicator to warn when the clock accuracy or operation has been affected, or to signal the triggering of a programmed event. The relay contacts are rated at 2.0 amps, 30VDC.

The web browser user interface allows the assignment to each relay of one of three functions:

Major Alarm, Minor Alarm, and Event Timer. For more details on these functions, see the

"Alarm Outputs" section and the "Configuring the Event Timer" section.

To configure or view the relay assignments:

Connect to the web browser user interface. If configuring, login to configuration mode (or administration mode). If just viewing, no login is needed. Along the bottom of the interface select Relay Setup. Along the left hand side, select Relay Output. A page showing the relays along the left side and the functions along the top will appear. To assign a function to a relay, click the dot that lines up with both the function and the relay. If just viewing, no assignments can be changed. See the below example.

Page 3-52

Figure 3-17: Relay Output Screen

Model 9189 Instruction Manual

To test the operation of the relays:

The relay operation of all three relays can be tested at any time as desired. To test the relay operation, login as administrator mode and click on “test relays” in the left orange bar. Chose the desired relay to be tested and then press submit. The selected relay should activate each time the submit button is pushed.

Example: To assign “Major Alarm” to relay 1, “Minor Alarm” to relay 2, and “Event Timer” to relay 3, click on the following dots.

Major alarm to relay 1: the dot in row 1, column 1.

Minor alarm to relay 2: the dot in row 2, column 2.

Event Timer to relay 3: the dot in row 3, column 3.

A single relay can only be assigned one function but a function can be assigned to multiple relays.

By default, all three relays are assigned “Major Alarm.”

Model 9189 Instruction Manual Page 3-53

3.14 SNMP

SNMP (Simple Network Management Protocol) is a set of standards for managing network devices, which includes a protocol, a database structure specification, and a set of data objects.

The communication protocol involves one or more network management stations monitoring one or more network devices. SNMP enabled devices must have an SNMP agent application that is capable of handling network management functions requested by a network manager. The agent is also responsible for controlling the database of control variables defined in the product’s MIB

(Management Information Base).

The SNMP setup page is used to configure the device’s SNMP agent. The following steps can be used to quickly configure the device’s SNMP agent while explaining the configuration options.

Login to the unit through the web browser user interface as administrator mode. Click on the

“System Setup” link on the bottom blue bar to open the menu for system configuration. Click on the “SNMP” link on the left side of the screen to enter the SNMP setup page.

The SNMP configuration page consists of five main sections, followed by the submit button.

The five sections (in order) consist of: SNMPv1 configuration, SNMPv2c configuration, Trap destination/version, trap selections and then SNMPv3. The descriptions of each of these sections are contained in the following.

Page 3-54

Figure 3-18: SNMPv1 Setup Screen

Model 9189 Instruction Manual

The radio buttons at the top of the page labeled “Disabled” and “Enabled” are used to determine if the SNMP agent is on or completely turned off.

The SNMP agent has a number of access schemes (SNMPv1, SNMPv2, SNMPv3) that can be individually enabled or disabled, depending on your specific needs. The check-box in front of each of the schemes is used to enable or disable that particular scheme. The schemes are described below.

SNMPv1 – By enabling this access scheme, SNMP network managers may use SNMP version 1 protocols to manage the device. A user-defined “Read” and a “Read/Write” community name used by SNMPv1 may be entered if desired.

Network access is used to restrict by “network IP address” who may query this SNMP agent.

This feature is also known as “host restriction”. If the user wishes to restrict SNMP access to one management station, say 192.168.0.1 then the network access should be set to

“192.168.0.1/32”. If the user wishes to allow any management station on the 192.168.0.X with subnet mask 255.255.255.0, then Network Access would be set to “192.168.0.0/24”.

Figure 3.14-2: SNMPv2 Setup Screen

SNMPv2c – By enabling this access scheme, SNMP network managers may use SNMP version

2 protocols to manage the device. A user-defined “Read” and a “Read/Write” community name used by SNMPv2c may be entered if desired.

Network access is used to restrict by “network IP address” who may query this SNMP agent. If the user wishes to restrict SNMP access to one management station, say 192.168.0.1 then the network access should be set to “192.168.0.1/32”. If the user wishes to allow any management station on the 192.168.0.X with subnet mask 255.255.255.0, then Network Access would be set to “192.168.0.0/24”.

Model 9189 Instruction Manual Page 3-55

Figure 3.14-3: SNMP Trap destination Setup Screen

Further down the page is the configuration of the SNMPv1 and SNMPv2c traps. The “trap” community name is used for both v1 and v2c traps. The destination table should be used to define which SNMP managers should be sent traps and which version they should receive(v1 or v2c). Up to five different traps destinations and their versions may be entered in the table. This feature is to support a “distributed SNMP Manager scenario”. For example, on a Wide Area network, traps can be sent to different geographic locations to coordinate the different Time zones and normal working hours of personnel.

Page 3-56 Model 9189 Instruction Manual

Figure 3.14-4: Trap selection Setup Screen

The “Individual Trap Enable/Disable” section allows the user to enable/disable any subset of the unit’s available traps. This list contains all of the available traps that may be sent from the

NetClock. Unchecking the box in front of each trap will prevent that particular trap from being sent.

Model 9189 Instruction Manual Page 3-57

Figure 3.14-5: SNMPv3 Setup Screen

The last section is for SNMPv3 configuration. This section allows the user to enable/disable any one of the three SNMPv3 security models. These models are described below:

SNMPv3 (noAuth) – By enabling this access scheme, SNMP network managers may use SNMP version 3 protocol to manage the device. No form of PDU (Protocol Data Units) authentication or DES encryption is used. You may specify your own user name for this level of access.

SNMPv3 (auth) – By enabling this access scheme, SNMP network managers may use SNMP version 3 protocol to manage the device. This level of SNMPv3 has you select a form of PDU authentication (MD5 or SHA) but does not use DES encryption. You may specify your own user name and pass phrase for this level of access. The pass phrase is the secret key shared between the SNMP agent and manager, used in the MD5 or SHA authentication algorithm. The Pass phrase must be a minimum of 8 characters long.

SNMPv3 (authPriv) – By enabling this access scheme, SNMP network managers may use

SNMP version 3 protocol to manage the device. This level of SNMPv3 also has you select a form of PDU authentication (MD5 or SHA) and performs DES encryption on all PDU’s. You may specify your own user name and pass phrase for this level of access. The pass phrase is the secret key shared between the SNMP agent and manager, used in the MD5 or SHA authentication and DES encryption algorithms. The pass phrase must be a minimum of 8 characters long. NOTE: This access method is only available on products that have the security option installed.

When SNMP is fully configured as desired, click the submit button.

Spectracom’s private enterprise MIB can either be obtained from the Spectracom Customer

Service department via an email or it can also be FTP’d (File Transfer Protocol) out of the

NetClock using an FTP agent such as Microsoft FTP, CoreFTP or any other shareware/freeware

FTP program.

To obtain the MIB file via FTP, using your FTP program, login to the administrative mode with the admin level password. Change the file transfer mode to “binary”. Navigate to the “MIB” directory which is located on the root directory. The Spectracom MIB files are located in this directory. There is a Global (generic) MIB file and a NetClock specific MIB file called “Time and Frequency”. FTP the files to your desired location on your PC for later transfer to the

SNMP Manager. The MIB files may then be compiled onto the SNMP Manager.

Note: When compiling the MIB files, some SNMP Manager programs may require the MIB files to be named something specific other than the current name for the files. The MIB file names (“Global” and “Time and Frequency”) may be changed or edited as necessary to meet the requirements of the SNMP Manager. Refer to the SNMP Manager documentation for more information on their requirements.

GPS Startup Self-Test

The GPS Startup Self-Test will indicate the status of the antenna, antenna cable and the GPS receiver at the time of power-up only. If the antenna cable was not connected, shorted or open at the time of power-up, and/or if there is a problem with the GPS receiver or antenna or both at the time of power-up, this test will indicate FAILED. “Antenna UC” means the antenna was not connected and “Antenna OC” indicates there was a short in the cable at the time of power-up.

“Antenna NV” means an unknown antenna problem existed at power-up. “GPS & Antenna” means that both GPS receiver and Antenna problems were detected at power-up.

Model 9189 Instruction Manual Page 3-61

GPS Antenna Sense

The GPS Antenna Sense is a current status of the antenna, antenna cable and the GPS receiver.

If the antenna cable is currently not connected, shorted or open, and/or if there is a problem with the GPS receiver or antenna or both, this test will indicate FAILED. “Antenna UC” means the antenna is not currently connected and “Antenna OC” indicates a short in the cable. “Antenna

NV” means an unknown antenna problem. “GPS & Antenna” means that both GPS receiver and

Antenna problems were detected.

Modem Test (Applicable only to units with Option 3: Modem installed):

The Modem Test will indicate “Console Mode” if the Serial Setup Interface is set to Console mode instead of Modem mode. This indicates that the modem is not currently being used. If the modem feature is desired, in the modem configuration page, change the mode to the Modem mode.

When the NetClock initially boots up, the mode is set to Serial Setup Interface is set to Modem and before every modem dial-out call, the modem is sent a command. If the unit gets a response from the modem, the field is set to PASSED. If the unit gets no response or a bad response from the modem, then the field is set to FAILED and the reason is indicated as shown below:

The System Features and Options section provides the current status of all the features and options that are available for your particular NetClock. Features that are currently turned on will indicate “ENABLED”. Features that indicate “DISABLED” are not enabled. However, the disabled features may be “enabled” after the original purchase.

Some of these features can be enabled in the field. If an option, which is enabled, fails to correctly initialize and become ready to be used its status is ERROR.

Page 3-62 Model 9189 Instruction Manual

With the features that can be enabled in the field, such as the Security option (Option 1) and

Modem option (Option 3), we will provide a “key hash” that will enable the feature to be turned on. Please contact our Sales department to purchase the option.

The purchase price of the Option 3 modem includes the cost for the modem as well as the key to enable the feature. The modem selection is very limited in compatibility. Not all available modems are compatible with the NetClock (Must be configured as Hayes AT), so we will supply you with a modem when the option is purchased. If the modem option was not initially purchased, contact our Sales department to purchase the modem option.

Model 9189 Instruction Manual Page 3-63

The System Time page provides a means to manually set the time for test purposes only. It also provides a handy and simple process to determine the time that the NetClock currently is set to.

This feature reads the information that the NetClock is providing to the external equipment that is syncing to this device.

To navigate to the System Time page, click on System Setup on the bottom blue bar and then on

System Time on the left orange bar. Refer to Figure 3-19 for more details. Note: You must be logged into the administrator mode to make any changes to this page.

Figure 3-19: System Time

The top section of the System Time page provides the ability to set and determine the current

UTC or local time that the NetClock is providing to the other devices it is syncing to.

Page 3-64 Model 9189 Instruction Manual

Local System Clock:

This field determines if the time output is displayed as UTC or one of the 5 possible local times that can be created using the Local System Clocks screen. When a Local System clock is selected here, the time displayed below it will be displayed as configured in that particular local

System Clock (i.e. Eastern time with automatic DST correction). After choosing the desired local clock from the drop-down, press the Submit button to accept the change. Click System Time again to bring the page back for viewing.

Current UTC Time: 17:59:10

(Elapsed time based on browser clock. Click 'System Time' to update.)

This line contains the current time displayed as configured in the Local System Clock dropdown.

The name in the line will indicate either UTC or the name of the selected local clock. Initially, this is a free-running clock that may or may not be the correct time (The Time displayed isn’t automatically corrected every second). To determine the current time at a particular moment, press System Time on the left orange bar. Pressing this button each time will cause the time displayed to be updated to the current time.

The bottom portion of the System Time page provides a means of manually setting the time and date. However, when the time and/or date is manually set by the user, the NetClock will not be synchronized and indicators in all of the outputs will be flagged as unsynchronized. Most time. software programs including NTP will ignore the NetClock when these status messages indicate that the NetClock is not synchronized.

When manually setting the time of the NetClock, the time is entered as UTC- not your local time. This means the time is not corrected for either Local Time or DST correction. Entering your local time will cause a several hour error in the NetClock outputs. The amount of error will depend on which Time Zone you are located in and whether we are currently in DST or in

Standard time.

Manually setting the time of the NetClock is not recommended as the outputs will likely be unusable because of the time sync status characters in the outputs. When an external reference is detected, the time and date will be automatically corrected to the real values and the manually set values will be overwritten. When this occurs, a log entry will be made in the Operational log indicating the amount of correction that was made from the manually set time. This log then shows if the time was ever manually set and then corrected by another external reference.

Note: Manually setting the time while synchronizing to the Option 3 modem will cause loss of

Time Sync which will automatically trigger a dial-out call to attempt to re-sync. Manually setting the time while synchronizing to GPS will immediately set the time back to the correct

Model 9189 Instruction Manual Page 3-65

The time interval between the loss of the primary external reference and the moment that the

NetClock declares loss of Time Sync is known as holdover. While the unit is in the holdover mode, the time outputs are derived from an internal oscillator. Because of the internal TCXO oscillator, accurate time can still be derived even after the primary reference is removed. The more stabile the oscillator is without an external reference, the longer this holdover period can be. The benefit of holdover is that time sync and the availability of the time outputs is not immediately lost when the reference is no longer available.

The NetClock has a user configurable variable holdover period so that it can be adjusted for personal requirements and desires. A user can change the length of time that a unit waits in the holdover mode before loss of time sync. The holdover can be defined by a specific number of hours to wait, such as 4 hours and 30 minutes.

The estimated error rates for the oscillator are listed below.

Estimated Error Rates Time to reach 2 ms

1.0 milliseconds / hour (nominal) 2 hours (typical)

7.2 milliseconds / hour (worst case) 17 minutes*

Table 3-4: Estimated oscillator error rates

Note: The TCXO Error rate is a worst-case estimate and not typically this value. The nominal value assumed has been 1 millisecond / hour yielding 2 hours holdover times.

Limits on the minimum and maximum length of allowable holdover have been placed on the oscillator as shown below in Table 3-5.

Minimum Length Maximum Length

15 minutes 24 hours

Table 3-5: Minimum and Maximum allowable holdover values

If the user sets the length below or above the limits or if the error is too small or large, they will be notified that the current setting is out of bounds.

To navigate to the Holdover configuration page, click on System Setup on the bottom (blue) bar, then click on Holdover in the left (orange) page. Configuration of this page requires admin level login.

Page 3-66 Model 9189 Instruction Manual

3.17.1 Setting the variable holdover value for the oscillator

The user interface for variable holdover looks like:

Figure 3-20: Variable holdover configuration

Using the “Hours” and “Minutes” adjustable boxes, the user can set the maximum time for the holdover period. If the length is set to a value greater than 24 hours and 00 minutes, the

NetClock will respond with “Could not set holdover time. Please ensure that holdover times

are greater than 15 minutes and less than 24 hours 0 minutes.

If the unit is currently in sync, the changes to the holdover period will take effect immediately.

If the unit is in holdover, these changes will not take effect until the next holdover period. To force the changes to take effect immediately, reboot the NetClock.

Time in Holdover

Time in Holdover displays either the amount of time that the NetClock has been in the holdover mode, or displays a phrase that the unit is not currently in the holdover mode. If the unit is currently in the holdover mode (Lost external reference but the unit is still “synchronized”), this field will show the number of days, hours, minutes and seconds that the unit has been in the holdover mode (Elapsed time from the last good external reference).

Model 9189 Instruction Manual Page 3-67

If the unit is not currently in holdover mode because it either currently receiving an external reference or because the variable holdover period has expired and the unit is no longer

“synchronized”, the phrase "Not In Holdover" is displayed instead.

Page 3-68 Model 9189 Instruction Manual

4 Operation

4.1 Front Panel

The front panel of the NetClock consists of one Ethernet connector which has two small indicator lamps, two main status LED’s and two optional LCD displays (Option 2). The two status lights are “Sync” and “Power”. The LCD’s are configurable to display various time, data, version information formats. Refer to Error! Reference source not found. for the standard configuration and Figure 4-2 for units with Option 2 installed.

The Model 9189 has two main status LED’s present on the front panel. These status lights provide the user with the indication that power is applied to the unit (Power LED) and that the

NetClock is currently synchronized or not synchronized (Sync LED). The power light will be blank if power is not applied or green if power is applied. The Sync light has many states to indicate the current status of the unit.

The Ethernet connector provides an interface to the network for NTP synchronization and to obtain access to the web browser user interface. The Ethernet connector has two small indicator lights just above the connector. These lights are known as Good Link (Green LED) and Activity

4.2 Rear Panel

The rear panel provides several different outputs that are available for interfacing the NetClock to various systems as well as a means of initially configuring the unit’s network settings. The rear panel also has a power jack for the power input, a connection for the GPS antenna and relay contacts for alarm monitoring and event alerts. Refer to Figure 4-3 for a drawing of the rear panel.

The GPS Antenna connection is an “N” type connector for the GPS input from the antenna.

The power jack is the input for the DC power.

There are three configurable alarm/event relays (Relays 1, 2, 3) available for remote alerts and

monitoring.

The Serial Setup Interface provides network and output port configuration capability.

The two RS-485 connectors (RS-485 ports 1 and 2) provide an RS-485 data output for synchronizing devices that accept an RS-485 input, such as wall display clocks and add-on Time

Servers.

Serial Comm 1 is a “DB9 female” connector that provides RS-232 data output to devices that can accept an RS-232 input for synchronization.

Serial Comm 2 (Optional- Installed with Option 2) is a second “DB9 female” connector that provides RS-232 data output to devices that can accept an RS-232 input for synchronization.

4.3.1 Reasons for a Leap Second correction

A Leap Second is an intercalary, one-second adjustment that keeps broadcast standards for time of day close to mean solar time. Leap seconds are necessary to keep time standards synchronized with civil calendars, the basis of which is astronomical. They are used to keep the earth’s rotation in sync with the UTC time.

If it has been determined by the International Earth Rotation and Reference Systems Service

(IERS) that a Leap Second needs to applied, this time correction occurs only at the end of a UTC month, and has only ever been inserted at the end of June 30 or December 31. A Leap Second may be either added or removed, but in the past, the leap seconds have always been added because the earth’s rotation is slowing down.

Historically, Leap seconds have been inserted about every 18 months. However, the Earth's rotation rate is unpredictable in the long term, so it is not possible to predict the need for them more than six months in advance.

The NetClock can be alerted of impending leap seconds by either of the following methods:

1. GPS Receiver – The GPS satellite system transmits information regarding a Leap second adjustment at a specific Time and Date an arbitrary number of months in advance.

2. Modem – (Applicable to only units with Option 3 Modem installed). During a modem dial-out call, the call service indicates that a Leap second adjustment at the end of this current calendar month will occur.

4.3.2 Leap Second alert notification

The NetClock will announce a pending Leap Second adjustment by the following methods:

1. Data Formats 2 and 7 on the Serial and Remote Ports contain a Leap Second indicator.

During the entire calendar month preceding a Leap Second adjustment, these Formats indicate that at the end of the current month a Leap Second Adjustment will be made by having a ‘L’ rather than a ‘ ‘ (space) character in the data stream. Note that his does not indicate the direction of the adjustment as adding or removing seconds. These formats always assume that the Leap Second will be added, not removed.

2. NTP Packets contain a Leap Indicator Bit. In the 24 hours preceding a Leap Second

Adjustment, the Leap Indicator Bits (2 bits) which normally are 00b for sync are 01b (1) for Add a Leap Second and 10b (2) for remove a Leap Second. The bit pattern 11b (3) indicates out of sync and in this condition NTP does NOT indicate Leap seconds. The

Sync state indicates leap seconds by indicating sync can be 00b, 01b, or 02b.

Page 4-6 Model 9189 Instruction Manual

Important Note: It is the responsibility of the client software utilizing either the Data Formats or NTP time stamps to correct for a Leap Second occurrence. The NetClock will make the correction at the right time. However, because computers and other systems may not utilize the time every second, the Leap second correction may be delayed until the next scheduled interval, unless the software properly handles the advance notice of a pending

Leap Second and applies the correction at the right time.

3. The Dynamic System Information box in the “System Status” page located under the web page of “Status and Logs” will display a Leap Second Status box indicating +1 or -1 Leap second adjustment at the end of the month to users during the entire calendar month preceding the actual adjustment. Refer to Figure 4-4 and Figure 4-5.

Figure 4-4: Negative Leap Second indication

Figure 4-5: Positive Leap Second indication

4.3.3 Sequence of a Leap Second correction being applied

1. The following is the time output sequence that the Model 9183 will utilize to apply the

Leap second at UTC midnight (Not local time midnight. The Local time at which the adjustment is made will depend on which Time Zone you are located in).

A) Sequence of seconds output when adding a leap second:

56, 57, 58, 59, 60, 0, 1, 2, 3, …

B) Sequence of seconds output when removing Leap seconds:

56, 57, 58, 0, 1, 2, 3, 4, …

Model 9189 Instruction Manual Page 4-7

2. An entry will be made in the Operational log that the time was adjusted for a Leap

Second.

A) An example log entry for a Positive Leap Second is as follows:

TIME= 23:59:59 DATE= 2005-12-31

System Clock Service

Leap second inserted at end of month.

B) An example log entry for a Negative Leap Second is as follows:

Page 5-2 Model 9189 Instruction Manual

5.3 Verify operation of a Serial port

If you want to verify the operation of a Serial port output, you can use a straight thru standard serial cable and a terminal emulator such as HyperTerminal or Procomm to view the output data.

The RS-232 DB9M to DB9F cable used with the Serial ports must be pinned as a straight through cable (1 to 1, 2 to 2, 3 to 3, etc. with the minimum pin-out for the cable being 2 to 2, 3 to

3 and 5 to 5). The cables supplied with many bench-top UPS’s as well as null modem cables will NOT work with this port.

To verify the operation of the Serial port, configure the terminal emulator program with the same baud rate as the port is configured for (such as 9600 baud). With the serial cable connected to the Serial port and with the port configured as “Request character” mode and the character set to a capital letter “T”, each time a Capital letter “T” is pressed, the port will respond with a time stamp (any other character other than a “T” will respond with a “*”).

If the port is configured as “multicast” mode, with the serial cable connected, the time stamp should be displayed on the PC every second.

If the time stamp is displayed on the PC, the Serial port is functioning. If the time stamp is not displayed, verify the serial cable, the port configuration for the correct baud rate and the configuration of the terminal emulation program. Refer to the Spectracom Application Note regarding HyperTerminal at http://www.spectracomcorp.com/support/pdf/using_hyperterminal.pdf

.

5.4 Verify operation of a Spectracom TimeTap

If you want to verify the operation of a Spectracom TimeTap, follow the same process as Section

0 but instead of connecting a serial cable into the PC, connect the TimeTap directly to the Serial comm port on the PC (A DB9 to DB25 adapter is required to verify operation of a Model 8178T

TimeTap).

The TimeTap outputs data every second without the need to type any characters. As long as the

TimeTap, the Remote output and the RS-485 cabling are good, a once-per-second data stream will be present on the monitor. If no data is seen, check the cabling, the baud rate of the Remote port, the Remote port itself and the terminal emulator configuration.

Please review this section prior to calling the Spectracom Customer Service Department. If the reception problem cannot be solved following the guidelines outlined in this section, please call for Customer Service at 585.321.5800.

Model 9189 Instruction Manual Page 5-3

Cable or connector problem: Antenna problem alarm and SNMP traps should be evident.

Measure the antenna cable resistance to verify the integrity of the cable and connectors. Remove the antenna cable from the rear panel of the receiver and measure the resistance from the coax center to shield. Refer to Table 5-3 for typical resistance values of the antenna and inline amplifier alone and when combined.

Table 5-3: Typical Antenna Cable Resistance Values

Failed Impulse Suppressor: The Model 8226 provides lightning protection when the outdoor

GPS antenna is used. The Model 8226 has high impedance when measuring from the center conductor to ground and a low throughput resistance. A failing impulse suppressor may be tripping prematurely. The easiest way to test the Model 8226 is to temporarily replace it with a

Type N barrel connector. If the receiver begins tracking satellites within 20 minutes, the impulse suppressor has failed and must be replaced.

Cable Length: The Model 8228 Indoor Antenna is supplied with 50 feet of antenna cable. Do not add cable. Excessively long or improper cable type may prevent the receiver from tracking satellites. Refer to Section 1.1 for cable recommendations when using the Model 8225 Outdoor

Antenna.

Antenna Location: The antenna must have a good view of the sky. Refer to Section 2.1 for indoor antenna guidelines and Section 1.1 for outdoor antenna guidelines.

Window Type: Windows with metal film coatings, metal screens or blinds may impede GPS reception. If a window-mount antenna is being used, place the unit into the single satellite mode of operation.

Cable Length: Excessively long or improper cable type may cause low GPS quality due to cable attenuation. Long GPS antenna lengths may require an inline amplifier or lower loss cable. Refer to Section 2.4.2 for GPS cable recommendations and Section 2.4.5 for inline amplifier information when using the Model 8225 Outdoor Antenna.

Page 5-4 Model 9189 Instruction Manual

The Model 8228 Indoor Antenna is provided with a 50-foot antenna cable. Do not substitute or add coax to the provided cable.

Antenna Location: The antenna must have a view of the sky with views to the horizon. Nearby obstructions can reduce the receiver’s ability to track the maximum number of satellites available.

Window Type: Windows with metal film coatings, metal screens or blinds may reduce GPS reception. If a window-mount antenna is being used, place the unit into the single satellite mode of operation. Refer to Section 3.5.2 for more information.

5.6 Modem Dial-out (Option 3) troubleshooting

This section provides assistance with troubleshooting the operation of the modem dial-out feature for those units that have option 3 installed. There are two procedures to verify proper operation of the modem operation. The first test procedure (Test 1) is to determine if the modem will operate and connect to NIST without the Master Clock connected. The second procedure

(Test 2) is to ensure the modem operates and connects to NIST when being controlled by the

Master Clock. For assistance, please contact Spectracom Tech support at the contact information located at the end of this document.

5.6.1 Test 1: To verify modem is dialing and connecting to NIST in stand-alone mode:

This test will verify the operation of the modem with the Master Clock disconnected and not controlling the modem. If this test does not pass, the problem is with either the modem, the phone line or with NIST. If this test passes, next try dialing out with the modem connected to the Master Clock and follow the procedure below for testing with the unit connected to the modem. (Below these procedures are a sample response of the interaction of the PC, Master Clock and modem). The modem MUST be connected to an analog phone line to operate (It will not operate on a digital phone line).

1) Disconnect the modem from the Serial Setup Interface connector on the rear panel of the

Master Clock.

2) Remove the null-modem adapter and plug the DB9 end of the cable into a PC’s Comm port and the DB25 end of the cable into the modem.

3) Open HyperTerminal, Procomm or any other terminal emulator program on the PC. Direct the program to the PC’s Comm port at 9600 baud.

4) The modem local echo is disabled by default. To see what you are typing, type ate1

6) Type atm1 <enter> to turn the modem speaker on (When the modem is connected to the

Spectracom clock, the unit will always disable the speaker if software is version 2.1.6 or below).

7) Type atdt 9w1-303-494-4774 <enter> to dial NIST. 40 consecutive time messages will be displayed. NIST will then disconnect the call.

Note: If you receive the initial connection and “CD” lights on the modem but the 40 time messages

are not received, the modem connected to NIST but NIST is having difficulties sending time

data. This can happen if NIST is experiencing heavier than normal traffic.

5.6.2 Test 2: Verify operation of the modem operation while connected to the

Spectracom Master Clock

Below is the verification that the modem is properly being controlled by the Spectracom Master

Clock and the modem is successfully dialing and connecting to NIST.

1)

For the modem to function with the NetClock, the modem mode needs to be selected in the Modem configuration page of the web browser user interface and the unit rebooted to accept the change from console mode.

2)

If the unit is already powered-up and not synchronized, choosing dial-out now and hitting submit will cause the unit to connect to NIST. If the unit is already synchronized, this option is not available (The dialout-now function is not available for operation if the NetClock is currently in either holdover mode or sync mode). To operate the modem if it is in currently in sync, disconnect the antenna and wait until the variable holdover period expires or power cycle the unit to clear the sync condition.

Then, the dial-out now function will be available.

3)

Once the NetClock has dialed and synchronized to NIST, the unit will be in holdover mode until the variable holdover period expires (Devices syncing to the NetClock will still sync) indicated by the sync light flashing green. After the variable holdover expires, the unit will declare loss of sync (Sync lamp turns red) or when the scheduled

Time Verification call occurs, the modem automatically dials NIST again. If connection is made, holdover is restored (Sync lamp flashes green again).

4)

Verify proper operation of the modem by observing the status of the front panel sync lamp flashing green after connection to NIST and verifying the Model dial-out logs as shown below. If the sync lamp is also flashing red, this is because the GPS antenna is disconnected from the Master Clock. This is not directly related to the modem dial-out feature but if the antenna has been connected in the past, it is related to the reason why the modem is now dialing-out unexpectedly (Antenna problem causing loss of GPS time Sync).

Note: Data Format 1 has an available modification that may be made to the data stream structure. Most external systems utilizing Data Format 1 will look for a single digit day of the month for day 1 through day 9, with a space in front of each digit ( ^1, ^2, ^3 … 10,11… ) whereas other systems need to see a two digit day of the month for all days 1 through 9 with a leading 0 instead of a space (01, 02, 03… 10,11…). If your device requires the two digit day of the month for days 1 through 9, the following procedure will change the Data Format 1 structure to provide this.

1) Connect to the Serial Setup Interface port with a PC running HyperTerminal OR telnet into the NetClock using the IP address of the NetClock.

A. To change Data Format 1 output on a Serial port to a leading 0, type:

ser fmt [1/2] 1 zero <enter> (Where 1 or 2 is the desired Serial port number)

B. To change Data Format 1 output on a Remote RS-485 port to a leading 0, type:

rem fmt [1/2] 1 zero <enter> (Where 1 or 2 is the desired Remote port

number).

C. To change Data Format 1 output on a Serial port back to a leading space, type:

ser fmt [1/2] 1 <enter> (Where 1 or 2 is the desired Remote port number).

D. To change Data Format 1 output on a Remote RS-485 back to a leading space,

type:

rem fmt [1/2] 1 <enter> (Where 1 or 2 is the desired Remote port

number).

8.1.1 Option 1 basics

Option 1 provides the NetClock with the ability to make a secure network connection with the network. When this option is enabled, secure algorithms may then be used to protect the passwords and traffic that are sent over the network when communicating with the unit.

If not initially purchased with the unit, Option 1 can be enabled (turned on) in the field. Please contact our Sales department to purchase this option. You will be sent a “Hash key” that can be entered in the NetClock to enable the security algorithms.

8.1.2 Security overview

In addition to providing login accounts with up to 16-character passwords supporting different privileges for the config and admin users, Spectracom products providing security features use

OpenSSH and OpenSSL. OpenSSH is the Open Source version of the Secure Shell; which provides a set of server side tools allowing secure remote telnet like access and secure file transfer using remote copy like (RCP) and FTP like utilities. OpenSSL is the Open Source version of Secure Sockets Library; which is used to provide the encryption libraries. Together

OpenSSH and OpenSSL provide industrial strength encryption allowing for secure remote administration via command line, HTTPS web pages and secure file transfers.

A convenient and simple web browser user interface is provided on units with Option 1 enabled, under the “System Setup” tab’s “Network” and “Security” sub menus. Users can configure their product and control the network access to the product by selecting options found under these menus. The Network sub menu allows the user to choose to enable or disable protocols such as

Telnet and FTP. The user can also as described in the Network menu section control their subnet and gateway. On secure products the user is permitted to enable or disable HTTP and SSH as well. The secure product can be configured to allow access only via NTP and the secure protocols such as HTTPS or SSH or to operate in a less secure mode. Spectracom secure products also provide a Security submenu. The security submenu provides the user with the means to configure their use of SSH and SSL.

Pop up help text is available for most Security web browser user interface features. Allow your cursor to hover over the box and help text box should appear.

OpenSSH implements a free version of Secure Shell. Secure Shell is a set of server and client tools supporting secure telnet like remote access and secure, authenticated file transfers using passwords and/or public key cryptography. The tools supported by units with Option 1 enabled are SSH – secure shell, SCP – secure copy, and SFTP – secure file transfer protocol. The Option

1 enabled units implement the server components of SSH, SCP and SFTP.

Page 8-2 Model 9189 Instruction Manual

For more information on OpenSSH please see www.openSSH.org

8.1.4 Managing Host Keys

SSH uses Host Keys to uniquely identify each SSH server. Host Keys are used for server authentication and identification. The secure Spectracom product allows the user to create or delete RSA1 keys for the SSH1 protocol or RSA or DSA keys for the SSH2 protocol.

8.1.4.2 Deleting Host Keys

The user may choose to delete individual Host Keys. To delete a key simply select a radio button for the key you wish to delete and press submit at the bottom of the page.

Figure 8-1: SSH configuration Screen

If the user chooses to delete the RSA1 key, the SSH1 protocol is not available and SSH1 clients will be unable to connect.

Model 9189 Instruction Manual Page 8-3

If the user chooses to delete the RSA or DSA key only the SSH2 protocol will function but that form of server authentication will not be available. If the user chooses to delete both the RSA and DSA keys the SSH2 protocol is not available and SSH2 clients will be unable to connect.

If the users chooses to simultaneously delete the RSA1, RSA and the DSA keys, SSH will not function. In addition, if SSH Host Keys are being generated at the time of deletion, the key generation processes are stopped, any keys created will be deleted, and all key bit sizes are set to

0.

The user may choose to delete existing keys and request the creation of new keys, however it is often simpler to make these requests separately.

8.1.4.3 Creating Host Keys

The user may create individual RSA1, RSA and DSA Host Public/Private Key pairs. Host Keys must first be deleted before new Host Keys can be created. To create a new set of host keys first delete the old keys, then select the create host keys checkbox and enter the key sizes you desire.

Then select the submit button at the bottom of the screen.

A typical Host Key generation request is shown below.

Page 8-4 Model 9189 Instruction Manual

Figure 8-2: Creating SSH host key files

Option 1 enabled products typically have their initial Host Keys created at the factory. The default key size for all key types is 1024. Host Key sizes can vary between 768 and 4096 bits.

The recommended key size is 1024. Though many key sizes are supported, it is recommended that users select key sizes that are powers of 2 or divisible by 2. The most popular sizes are 768,

1024, and 2048. Large key sizes up to 4096 are supported, but are discouraged because they take hours to generate.

Host Keys are generated in the background. Creating an RSA1, RSA and DSA keys each with

1024 bits length, typically takes about 10 minutes. Keys are created in the order of RSA, DSA and finally RSA1. When the keys are created you can successfully make SSH client connections. If the unit is rebooted with Host Key creation in progress or the unit is booted and no host keys exist the key generation process is restarted. The key generation process uses either the previously specified key sizes or if a key size is undefined it defaults to 1024. A key with a zero length or blank key size field is not created.

Model 9189 Instruction Manual Page 8-5

Note also that when you delete a Host Key and recreate a new one, SSH client sessions will warn you that the host key has changed for this particular IP address. The user will either have to override the warning and accept the new Public Host Key and start a new connection or they may need to remove the old Host Public Key from their client system and accept the new Host

Public Key. Please consult your specific SSH client’s software’s documentation.

8.1.4.4 Selecting SSH Authentication Mode

The SSH client utilities SSH, SCP and SFTP allow for several modes of user authentication.

SSH allows the user to remotely login or transfer files by identifying the user’s account and the target machines IP address. Users can be authenticated by either using their account passwords or by using a Public Private Key Pair. Users keep their private key secret within their workstations or network user accounts and provide the Spectracom secure product a copy of their public key.

To select an Authentication mode admin users select an option from the Authentication section and select submit at the bottom of the page.

Page 8-6

Figure 8-3: Selecting SSH authentication modes

Model 9189 Instruction Manual

The modes of authentication supported include:

• Either Public Key with Passphrase or Login Account Password

• Login Account Password only

• Public Key with Passphrase only

The first option allows users to login using either method. This is the default. Whichever mode works is allowed for logging in. If the Public Key is not correct or the passphrase is not valid the user is then prompted for the login account password. The second option simply skips public/private key authentication and immediately prompts the user for password over a secure encrypted session avoiding sending passwords in the clear. Finally the last option requires the user to load a public key into the Spectracom secure product. This public key must match the private key found in the users account and be accessible to the SSH, SCP or SFTP client program. The user must then enter the passphrase after authentication of the keys to provide the second factor for 2-factor authentication.

8.1.4.5 Managing Public Keys used for SSH Authentication

SSH using public/private key authentication is the most secure method of authenticating users for SSH, SCP or SFTP sessions.

The web browser user interface provides the means for the user to delete the

/sys/.SSH/authorized_keys file, to add individual Public Keys and comments to the existing file, and to copy a file containing Public Keys from the /sys/update folder to a file named

/sys/.SSH/authorized_keys. Using FTP, SCP or SFTP the user may also retrieve the read-only authorized_keys file from the /sys/.SSH directory.

An example of a user adding a public key to the authorized_keys file is shown below.

Model 9189 Instruction Manual Page 8-7

Figure 8-4: Adding SSH public key to authorized keys

Users are required to create private and public key pairs on their workstation or within a private area in their network account. These keys may be RSA1, RSA or DSA and may be any key bit length as supported by the SSH client tool. These public keys are stored in a file in the /sys/.SSH directory named authorized_keys. The file permissions are to be read-write for root and readonly for all other users. The file is to be formatted such that the key is followed by the optional comment with only one key per line. The Spectracom application terminates each line with a carriage return and separates each line with a blank line. The file format, line terminations and other EOL or EOF characters should correspond to UNIX conventions, not Windows.

If a user deletes all Public Keys Public/Private Key Authentication is disabled. If the user has selected SSH authentication using the “Public Key with Passphrase” option login and file transfers will be forbidden. The user must select a method allowing the use of account password authentication to enable login or file transfers using SCP or SFTP.

If a user wants to completely control the public keys used for authentication a correctly formatted authorized_keys file formatted as indicated in the OpenSSH web site can be loaded onto a secure Spectracom product. The user transfers a new public key file using an insecure

Page 8-8 Model 9189 Instruction Manual

FTP client or a secure SCP or SFTP client using only account password authentication. The user should place the new public key’s file in the /sys/update directory. The user then selects the delete all public key’s checkbox, selects the update public key’s checkbox and enters the filename in the space provided.

An example of a user adding a new public key file is shown below.

Figure 8-5: Adding a new SSH public key file

The MyPublicKeys.txt file in the /sys/update directory is renamed and placed in the /sys/.SSH directory under the new name authorized_keys after the user selects the submit button at the bottom of the screen. Users can now authenticate using Private Keys, which match these public keys if the authentication mode supports “Public Key with Passphrase” authentication.

8.1.4.6 Secure Shell Sessions

Secure shell sessions using an SSH client can be performed using the admin or config accounts.

The user may use Account Password or Public Key with Passphrase authentication. Please be patient it can take a few minutes to establish a secure SSH session. The OpenSSH tool SSH-

Model 9189 Instruction Manual Page 8-9

KEYGEN is used to create RSA1, RSA and DSA keys used to identify and authenticate user login or file transfers.

The following command lines for OpenSSH SSH client tool are given as examples of how to create a secure SSH session.

1. Creating an SSH session with Password Authentication for the admin account. ssh [email protected]

[email protected]'s password: admin123

The user is now presented with Boot up text and/or a “>” prompt which allows the use of the Spectracom command line interface.

2. Creating an SSH session with Password Authentication for the admin account. ssh [email protected]

[email protected]'s password: config12

The user is now presented with Boot up text and/or a “>” prompt which allows the use of the Spectracom command line interface.

3. Creating an SSH session using Public Key with Passphrase Authentication for the admin or config account.

The user must first provide the secure Spectracom product a RSA public key found typically in the OpenSSH id_rsa.pub file. The user may then attempt to create an SSH session. ssh -i ./id_rsa [email protected]

Enter passphrase for key './id_rsa': mysecretpassphrase

Please consult the SSH client tool’s documentation for specifics on how to use the tool, select

SSH protocols, and provide user private keys.

8.1.4.7 Secure File Transfer

Option 1 enabled units provide secure file transfer using the SSH client tools SCP and SFTP.

Authentication is performed using either Account Passwords or Public Key with Passphrase.

However unlike SSH where the config or admin accounts are used, a special user account is provided named “SCP” for these tools. The “SCP” user account has the same password as the admin account. It differs from the admin and config accounts in that it does not run the

Spectracom product shell. It is a limited account that only allows the user to transfer files to and from the /sys/update folder and to retrieve files from folders which the SCP account has read permission.

Some sample OpenSSH, SCP and SFTP client commands are shown below.

1. Perform an SCP file transfer to the device using Account Password authentication

Page 8-10 Model 9189 Instruction Manual

scp publickeys [email protected]

:/sys/update [email protected]'s password: admin123 (Always use same password as admin) publickeys 100%

|***************************************************| 5 00:00

2. Perform an SCP file transfer from the device using Public Key with Passphrase authentication. scp -i ./id_rsa publickeys [email protected]

:/sys/update

Enter passphrase for key './id_rsa': mysecretpassphrase publickeys 100%

|***************************************************| 5 00:00

3. Perform an SFTP file transfer to the device using Account Password authentication. sftp -i ./id_rsa [email protected] [email protected]'s password: admin123 (Always use same password as admin)

sftp>

The user is presented with the SFTP prompt allowing interactive file transfer and directory navigation.

4. Perform an SFTP file transfer from the device using Public Key with Passphrase authentication sftp -i ./id_rsa [email protected]

Enter passphrase for key './id_rsa': mysecretpassphrase

sftp>

The user is presented with the SFTP prompt allowing interactive file transfer and directory navigation.

8.1.4.8 Recommended SSH Client Tools

Spectracom does not make specific recommendations as to which specific SSH client, SCP client, or SFTP client tools. However, there are many SSH based tools available at cost or free to the user.

Two good, free examples of SSH tool suites are the command line based OpenSSH running on a

Linux or OpenBSD x86 platform and the excellent and free putty SSH tool suite.

Model 9189 Instruction Manual Page 8-11

The OpenSSH tool suite in source code form is freely available at www.openSSH.org

though you must also provide an OpenSSL library, which can be found at www.openssl.org

.

The putty SSH tools and instructions regarding their use can be found at:

HTTP://www.chiark.greenend.org.uk/~sgtatham/putty/

Note that it is strongly recommended to exit all SSH client sessions preferably using the “exit” command or “control-C” to avoid leaving the SSHd daemon running. Exiting the putty tool (or

SSH clients tools) by selecting the windows “X” button can leave the SSHd session running and result in refused connections until it times out after extremely long timeout delays. In such a case a reboot might be preferable rather than waiting.

8.1.5.1 Overview

The OpenSSL library provides the encryption algorithms used for secure HTTP (HTTPS). The

OpenSSL package also provides tools and software, which is used to create x509 Certificate

Requests, Self Signed Certificates and Private/Public Keys. The Option 1 enabled units use

OpenSSL library with a simple GUI interface to create certificate Requests and self-signed certificates. Users can then send these certificate requests to an external Certificate Authority

(CA) for the creation of a third party verifiable certificate or use an internal corporate CA. If a

Certificate Authority is not available the user can simply use the self-signed certificate that comes with the unit until it expires or create their own self-signed certificates to allow the use of

HTTPS.

The NetClock comes with a default Spectracom self-signed certificate, which will outlast the product warranty. The typical expiration of the certificate is about 10 years. HTTPS is available using this certificate until this certificate expires. If deleted however, this certificate cannot be restored.

For more information on OpenSSL please see www.openssl.org

.

The user is has the option of deleting the current certificate, certificate requests and private key.

To choose the delete option simply check the delete checkbox and press the submit button at the bottom of the screen. Once the current certificate is deleted, HTPS is unavailable.

Page 8-12 Model 9189 Instruction Manual

Figure 8-6: Deleting SSL Certificate, Certificate Request and Private Key Files

8.1.7 Restoring Self Signed Certificates and Private Keys

The user has an option to restore the last self signed certificate and private key created by the user. To restore these files the user needs to select the “Restore User’s Self Signed Certificate and Private Key” checkbox. The user then selects the submit button at the bottom of the screen.

The default Spectracom self-signed certificate and private key cannot be restored when deleted.

Model 9189 Instruction Manual Page 8-13

Figure 8-7: Restoring user’s Self Signed Certificate and Private Key Files

8.1.8 Creating Self Signed Certificates, a Private Key, and a Certificate Request

The user can create a customer specific x509 self-signed certificate, an RSA private key and x509 certificate request using the web browser user interface. RSA private keys are supported because they are the most widely accepted. At this time DSA keys are not supported.

The user is required to select a signature algorithm, a private key passphrase of at least 4 characters, a private key bit length, the certificates expiration in days and at least one of the remaining fields. It is recommended that the user consult their Certificate Authority for the required fields in an x509 certificate request. Spectracom recommends all fields be filled out and match the information given to your certificate authority. For example, use all abbreviations, spellings, URLs, and company departments recognized by the Certificate Authority. This helps in avoiding issues with the Certificate Authority having issues to reconciling certificate request and company record information.

If using only self-signed certificates the user should choose the fields based upon the company’s security policy.

A sample input screen to create a certificate request is shown below.

Page 8-14 Model 9189 Instruction Manual

Figure 8-8: Creating a new Certificate Request and Self Signed Certificate

Note that it can take several minutes for the certificate request, the private key, and self-signed certificate are created. The larger the key the longer amount of time is required. It is recommended that a key bit length be a power of 2 or multiple of 2. The key bit length chosen is typically 1024, but can range from 512 to 4096. Long key bit lengths of up to 4096 are not recommended because they can take hours to generate. The most common key bit length is the value 1024.

The user is provided with several signature algorithm choices. The signature algorithm or message digest is most commonly MD5. Other secure options include SHA1 and RMD160.

Model 9189 Instruction Manual Page 8-15

Consult your Web Browser documentation and Certificate Authority for key bit lengths and signature algorithms supported.

If a system is rebooted during this time, the certificate will not be created. When the operation is completed, the user will see a certificate request in the certificate request text box. A digital file copy of the certificate request can be found in the /sys/update directory with the file name cert.csr. This file can be retrieved using FTP, SCP or SFTP. The certificate request can also be cut and paste from the certificate request text box on the web browser user interface.

Once the processing to create the certificate request, RSA private key and self-signed certificate is completed the browser user interface will display the certificate request.

A certificate request is shown below.

Figure 8-9: A new Certificate Request and Self Signed Certificate

The user can submit this certificate request to the company’s Certificate Authority for a real verifiable, authenticable third party certificate. Until this certificate is received the user’s selfsigned certificate displaying the information shown above can be used.

Page 8-16 Model 9189 Instruction Manual

The Option 1 enabled units web server will load this new self-signed certificate and private key after the user selects a few more web page options or when the user selects the “Exit connection to product” button at the top of the screen. The user will see a pop up window in Windows operating systems. The certificate and be installed or viewed using this pop up window. Other operating systems may vary in how they install and accept certificates. External Internet access may be required by your Certificate Authority to verify your third party certificate.

After your Certificate Authority issues you a Certificate you need to install it on the secure

Spectracom product. Certificates may be installed via the web browser user interface and stored.

Or they may be copied to the /sys/update directory using file transfer and installed using the web browser user interface.

A sample certificate installation using the Certificate text box on the web browser user interface is shown below.

Figure 8-10: Installing a new Certificate

The user needs to cut and paste the certificate into the Update Certificate text box and select the checkbox. The user then enters submit at the bottom of the page and the current self-signed certificate is overwritten.

Model 9189 Instruction Manual Page 8-17

If the file transfer method is chosen FTP, SCP, SFTP may be used to copy the certificate text file to the /sys/update/ directory using any file name. The user then selects the “Update Certificate with file named” check box and enters the file name in the space. The user then enters submit at the bottom of the page and the current self-signed certificate is overwritten with the specified file name.

In both cases the secure Spectracom product’s web server loads this new self-signed certificate and private key after the user selects a few more web page options or when the user selects the

“Exit connection to product” button at the top of the screen.

The user is provided with another means to load certificates onto the secure Spectracom product supported. The certificate must be in PEM format.

The user may install the externally generated certificate using the web browser user interface. A sample certificate install is shown below.

Page 8-18

Figure 8-11: Using External Certificate

Model 9189 Instruction Manual

The certificate can also be installed using file transfer and the web browser user interface. The user simply needs to transfer the certificate file to the /sys/update directory using either SCP or

SFTP. Once the file is transferred, the user simply selects the “Update Certificate with file named” checkbox and provide the file names. The user then enters the submit button.

In both cases the secure Spectracom product’s web server loads this new self-signed certificate after the user selects a few more web page options or when the user selects the “Exit connection to product” button at the top of the screen.

To successfully use this means of certificate generation the user must correctly create a certificate which complies with the requirements of the currently used OpenSSL release.

8.1.12 What to do if you cannot get into a secure Spectracom Product

Spectracom assumes that the customer is responsible for the physical security of the product.

Spectracom secure products are required to be locked in a secure enclosure, cabinet or room.

Unauthorized persons are not to be given access to the product nor should a serial cable and terminal program be attached unless the system administrator is configuring or performing maintenance.

If your company disables HTTPS, loses the system passwords, allows the certificate to expire, deletes the certificate the certificate and private keys and deletes the Host Keys or forgets the passphrase access to the secure Spectracom product can become denied.

To restore access to your system you must utilize the setup port to restore the admin accounts default password. The admin account can then be used to enable HTTP using the “net HTTP” command. Contact Spectracom Technical Support for details on how to do this.

Model 9189 Instruction Manual Page 8-19

Option 3 provides the NetClock with the capability to use a modem to dial-out via an analog phone line for time retrieval if GPS reception is either lost or cannot be obtained due to site limitations. The modem can be configured in the software as either the primary external time reference or it can also be configured as a Secondary/Backup reference in case the primary reference is lost.

The modem interfaces to the NetClock via the Serial Setup Interface located on the rear of the

NetClock. This dual-function port provides the capability to initially configure the network settings and is also the interface for the modem.

If not initially purchased with the unit, Option 3 can be enabled (turned on) in the field. Please contact our Sales department to purchase this option. You will be sent a Hash key that can be entered in the NetClock to enable the security algorithms. The purchase of the option includes a

Spectracom supplied compatible modem.

Note: The modem MUST be Hayes AT compatible and configured for this mode of operation to operate correctly with the unit. The Spectracom supplied modem is Hayes AT compatible.

• The cable needed to connect the modem to the NetClock is a DB9 male to DB25 male null modem serial cable. This cable should come with the modem package.

1) Connect the null modem converter that comes with the serial cable to the DB9 end of the cable.

4) Connect the modem power adapter to a power outlet.

2) Connect the DB25 side of the null modem converter to the modem and the modified DB9 side to the Serial Setup port located on the rear of the NetClock.

3) Connect the CAT2 telephone cable from the analog phone line to the modem.

8.3.3.1 Using the web browser user interface to configure dial-out modem feature:

The modem dial-out feature is used as either a Secondary/Backup time reference when all other external time references become unavailable or can also be used as a primary reference if an external reference is not available for use (Such as the inability to receive GPS at a particular

Model 9189 Instruction Manual Page 8-23

location). The Modem dial-out Configure web browser user interface provides options to configure the operation of the dial-out modem feature. Login to either the configuration or administrator-level mode if changes are desired. All fields will display the current system settings. The Modem dial-out configuration screens are accessed from the "System Setup" page on the bottom frame, and then select the “Modem Dial Out” from the left frame.

There are four different types of modem dial-out calls that can be made. The call type is determined by the state of the system (after the call is finished) as well as user input. Calibration calls happen upon a user request. Time verification calls happen on a user specified interval if holdover is entered from time sync with another source. Time sync calls happen when time sync is lost and on a user specified interval until another time source is available. Modem test calls happen when no calls have been made for a user specified time, or upon a user request. Because the modem determines how to use a call after the call is finished it is possible to start a call as a certain call type and actually use it as another call type. Here is a description of each of the four possible call types.

Calibration calls are done to characterize the call latency. A user specified number of calls will be made over the calibration period and the average latency will be used to adjust all future calls.

The calibration will only be done at the user’s request and may be started only while in sync from another time source. Calibration calls may be continued into holdover, but will be cut off if the unit goes out of sync at any point during the calibration period.

Time verification calls are made to verify the unit still has acceptable time and to correct for any leap seconds that may be asserted while the reference is not available. Calls will be made on a user specified time table. If the call interval is more than a month leap seconds may be missed.

If a leap second is to be inserted at the end of the month then the clock will be scheduled to do so. If the time is off by more than half a second then the unit will be immediately put into unsynchronized mode (Time sync lamp will extinguish and time outputs will be ignored).

8.3.6 Time Sync Call

Time sync calls are done to set the second and sub second timers and to check for any leap seconds. If a call is successful the timer will be set and the unit will be put in holdover mode with the holdover timer reset. In addition if a leap second is to be inserted at the end of the month then the clock will be scheduled to do so. Time sync calls will be made once the unit has gone into unsynchronized mode until it obtains sync from another time source. During this period, calls will be made on a user specified timetable or any time the unit goes out of sync.

8.3.7 Modem Test Call

Test calls are calls that make sure the modem is working. The modem will call out and check for valid time messages. The unit will log “test passed” if it was able to get good time messages or failed if it was not. No changes will be made to the system time. Testing can be done only in sync from another time source and can either be on a specified interval or as requested.

Page 8-24 Model 9189 Instruction Manual

Figure 8-13: Modem Dial-Out CONFIGURE Screen

Serial Setup Port Mode:

The modem is connected to the Serial Setup port for normal operation. On the Modem

Configure page is a pull-down menu to select the mode that the Serial Setup Port will operate in.

Two options are available:

Console Mode: In this mode, Serial Setup port can be connected with a serial cable to a computer with a serial terminal program running. The serial setup software commands can then be used to interface with the unit. The modem operation will not be available while selected to this mode.

Modem Mode: In this mode, the Serial Setup port can be connected to a modem for dialing out. The Serial Setup port will be unavailable for network configuration while in this mode.

Note: The unit must be rebooted to apply the changes made to the serial setup port mode.

Model 9189 Instruction Manual Page 8-25

Modem as Primary/Secondary time source

The modem can be configured as either the primary reference or a secondary/back-up mode of operation. This selection is configured on the Modem dial-out Configure page. In the

Secondary/Back-up mode of operation, all GPS antenna problem alarms (Indicating a short or open in the antenna cable) and SNMP traps associated with the GPS reference input will be fully enabled. When the modem Primary mode of operation is selected, the antenna problem alarm and associated SNMP traps for the antenna will not be generated. No indication of a problem with the GPS cable will be present or available. The Modem mode of operation does not affect the ability to receive GPS.

Note: If the unit initially operated without a GPS reference and primary mode of operation was selected, then at a later time a GPS antenna is connected, the mode of operation should be changed to secondary mode to enable the GPS antenna problem alarms to aide in troubleshooting.

Dialout now:

(Only available in Modem Mode and only when the unit is not in time sync).

Checking this box and clicking submit will prompt the dial out modem software to attempt an immediate dial out procedure with the current settings if the unit is currently out of sync. When a unit is configured in modem mode while it is in time sync, the “Dialout now” checkbox will be greyed-out (disabled).

Modem speaker: Toggles the modem speaker on or off during dial out.

Page 8-26 Model 9189 Instruction Manual

8.3.9 Modem Dial-out DIALOUT page

Figure 8-14: Modem Dial-Out DIALOUT Configure Screen

Model 9189 Instruction Manual Page 8-27

The model dial-out DIALOUT page is used to annotate the phone number used to obtain the time from and to determine how often the modem will be used to retrieve the current time.

Phone Numbers:

Prefix: The phone prefix is a number(s) that need to be dialed to reach an outside line.

Predefined: Stores two predefined number NIST-Colorado and NIST-Hawaii. These are the phone numbers to the National Institute of Standards and Technology modem time service.

Specified Number: This field will take any phone number that the user would like to use to dial out to obtain time.

Try Calling: This field specifies how many times the dial out modem software will try to connect to the selected phone number. Setting this field’s value to 0 will generate a warning because it will prevent any dial out to be made in any condition, effectively disabling the modem dial out feature.

Call Interval:

The call interval is used to manually configure how often the modem should dial-out for Time verification calls when the unit is in the holdover mode and Time Sync is normally derived from

GPS (Secondary/Backup mode of operation) or Time Sync calls when the modem is selected as the primary mode of operation.

To prevent a leap second occurrence from being missed and a one second error being inserted into the NetClock, we recommend the Time Verification calls be placed less than once-permonth. Setting the Time Verification call period to longer than once-per-month can result in a one second error from the time a leap second is asserted by NIST until the next Time

Verification/Time Sync call is placed.

To help prevent a loss of Time Sync condition from occurring, the call interval should be configured for a value of less than the holdover period. This will prevent the holdover period from expiring (which will cause loss of Time Sync) because the modem was configured to dialout after the holdover expired. For example, if the holdover period is set for two weeks, the call interval should be set to dial-out less than every two weeks. Otherwise, holdover will expire before the modem is scheduled for a dial-out and Time Sync will be lost.

Boot dial-out:

This field specifies how long the modem software will wait after being powered up to check the unit’s time sync status. If this time expires and the unit has not achieved time sync yet, the modem software will automatically dial out with the current settings at that time. Note that changes to this timer’s settings will not change the timeout of the current countdown if it has already begun (e.g. If the timer is set to 1 hour and then rebooted, the unit will countdown to 1 hour at power up. Changing the timer’s settings to 30 minutes will not affect the current

Page 8-28 Model 9189 Instruction Manual

countdown. The new 30 minutes value will only be used if another power cycle occurred). If want to skip the initial countdown, you can always use the Dialout Now feature.

If the modem is the primary mode of operation for Time sync, the boot dial-out value should be set for a very short duration as the unit will not be able to achieve time sync without the modem placing a call. If the modem is strictly a backup to the external reference, this period can be lengthened to longer than the typical amount of time needed to synchronize to the external reference.

Model 9189 Instruction Manual Page 8-29

Figure 8-15: Modem Dial-Out CALIBRATE Screen

The Modem dial-out calibrate screen is used to calibrate the modem for increased accuracy of the dial-out calls. The calibration procedure is not required but may be used to provide greater accuracy of future modem calls. The calibration process, using several dial-out helps compensate for inherit internal software processing lags as well as phone network delays as well.

Different locations may experience different latencies as well as time of day latencies may also vary.

The calibrate mode allows the user to define the typical latency for the geographic location as well as the time of day the modem is most likely to be used for time sync (such as for primary mode of operation).

Page 8-30 Model 9189 Instruction Manual

Calibrate Status:

The status of calibration is displayed at the top of the screen. If the calibration has been made then the unit will say “calibrated”. If the latency has not been set or has been manually set, then the unit will say “not calibrated”. If the unit is currently calibrating then the number of successful calls will be displayed here.

Calibrate Now:

Calibrate now is based on the current settings. This will calculate the call latency and adjust all future calls based on this value. The call latency is based primarily on the phone system.

Therefore, this should be done when the unit is first set up and does not need to be done again unless it is connected to a different phone system.

Reset Latency Value:

This resets the latency value to the factory default. This can be done if the unit was accidentally set.

Latency Value/Manually Set Latency:

This box displays the current latency value. If the “manually set latency” box is checked then this can be edited to set the current latency.

Number of Calibration calls:

This is the number of calibration calls to be made before the modem is declared as calibrated.

The accuracy of the latency calculation depends directly on this number. The more calls that are made, the more accurate the calculation will be. This should not be lowered from the default, but it may be safely raised.

Calibration Call Interval:

This is the interval between calibration calls. This value, along with the number of calibration calls, will determine how long the calibration process will take.

11. Review the changes made and click Submit. The browser will ask for the unit to be rebooted to apply the changes to the setup serial port mode.

12. Reboot the unit.

13. After the reboot, the unit will function in modem mode. If you need to dial out immediately, connect a modem to the setup serial port and then check the ‘Dialout now’ box and click

Submit. Recall that this option will only be available if the unit is not in time sync. If you have set the “Dialout if now sync after” timer, the timer will begin counting down as soon as the software is started.

14. To observe the result of the dial out, monitor the Dialout Log.

Once a dialout procedure is finished successfully, the unit’s state will be in sync. The unit’s internal oscillator maintains this sync state for a duration of time called the holdover period.

During this time, there is no need to dialout again hence the dialout option is disabled.

Page 8-34 Model 9189 Instruction Manual

There will be time periods when NIST’s ACTS telephone lines are used up. If you are unable to connect, please try again at another time. Also, verify that your phone line is analog.

If you forgot you network settings while in modem mode:

While in modem mode, the setup serial port will still respond to the ‘net show’ command.

Disconnect the modem from the setup serial port and attach a serial cable to a PC with a terminal software running as if you are connecting in console mode. Type ‘net show’ and the current network settings will be displayed. Use this information to connect to the unit through telnet or the web browser user interface to communicate with the unit.

Note: For additional assistance with troubleshooting the modem functionality, please refer to

Section 5.6.

This file is part of the OpenSSH software.

The licences which components of this software fall under are as follows. First, we will summarize and say that all components are under a BSD licence, or a licence more free than that.

OpenSSH contains no GPL code.

1)

* Copyright (c) 1995 Tatu Ylonen <[email protected]>, Espoo, Finland

* All rights reserved

*

* As far as I am concerned, the code I have written for this software

* can be used freely for any purpose. Any derived versions of this

* software must be clearly marked as such, and if the derived work is

* incompatible with the protocol description in the RFC file, it must be

* called by a name other than "ssh" or "Secure Shell".

[Tatu continues]

* However, I am not implying to give any licenses to any patents or

* copyrights held by third parties, and the software includes parts that

* are not under my direct control. As far as I know, all included

* source code is used in accordance with the relevant license agreements

* and can be used freely for any purpose (the GNU license being the most

* restrictive); see below for details.

[However, none of that term is relevant at this point in time. All of

these restrictively licenced software components which he talks about

have been removed from OpenSSH, i.e.,

- RSA is no longer included, found in the OpenSSL library

- IDEA is no longer included, its use is deprecated

- DES is now external, in the OpenSSL library

- GMP is no longer used, and instead we call BN code from OpenSSL

- Zlib is now external, in a library

- The make-ssh-known-hosts script is no longer included

- TSS has been removed

- MD5 is now external, in the OpenSSL library

- RC4 support has been replaced with ARC4 support from OpenSSL

- Blowfish is now external, in the OpenSSL library

WRITING

WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR

DAMAGES,

1 Changes for v2.3.0 to v2.3.1

9189 – v2.3.1

This addendum to the operations and maintenance manual for the Spectracom

NetClock

®

Model 9189 (current to software version 2.3.0) describes the changes made to software features for version 2.3.1. These changes include additions and enhancements to the Web User Interface (Web UI), to the command line, and in SNMP.

2 Network and Web User Interface Changes

The user may now enable and disable all network interfaces. The HTTPS port has been added to the Web UI and may be controlled on the System Setup web page on the Network tab.

Figure 2-1: Enabling and Disabling Network Interfaces

Allowing the user to enable and disable at will all network interfaces provides greater security and stability of the NetClock in hostile network environments. It also allows users to comply with corporate security policies regarding network access.

9189 v2.3.0 to v2.3.1 Addendum

1-1/2-1

9189 – v2.3.1 Spectracom Corporation

2.1 Command Line Changes

The network interface command line now allows the user to enable and disable all ports for Telnet, FTP, HTTP, HTTPS and SSH.

The new commands for the network interface are:

telnet net telnet [yes,no] – Enable or disable telnet on port 23

ftp net ftp [yes,no] – Enable or disable ftp on port 21

https net https [yes,no] – Enable or disable https on port 443

sshd net sshd [yes,no] – Enable or disable ssh on port 22

This command allows user to enable or disable the telnet port. Input yes to enable no to disable. Input net telnet yes to enable and net telnet no to disable.

This command allows user to enable or disable FTP the port. Input net ftp yes to enable and net ftp no to disable.

This command allows the user to enable or disable the HTTPS port controlling access to the secure web server. Enter net https yes to enable and net https no to disable.

2.1.4 net sshd (Includes SSH, SCP, and SFTP)

This command allows the user to enable or disable the SSH port controlling access to secure SSH protocols SSH secure shell, SCP secure copy, and SFTP secure file transfer. Input net sshd yes to enable and net sshd no to disable.

2.2 Web Server Timeout

The manner in which the GoAhead Web Server functions requires users to terminate

Web UI sessions by clicking “Exit Connection to the Product”. Clicking the “X” button on the browser does not end the session, but closes the window – which means the user cannot log in again until the session expires. In some versions of the software, this is

15 to 30 minutes, which some users find inconvenient.

Version 2.3.1 software includes new console commands that allow administrator-level to users to exit the current locked Web UI session using telnet or ssh. Also added is a command to set the timeout to a user-defined value, which means users may now dictate the length of time it takes for the session to expire.

2-2

9189 v2.3.0 to v2.3.1 Addendum

Spectracom Corporation 9189 – v2.3.1

Use the 'web help' command to see a list of net commands. These include web exit and web timeout minutes (to set the connection timeout).

This command allows the user to exit the current web session from telnet or ssh connections.

This command allows the user to set the web session timeout to any value between 1 and 60 minutes (inclusive). Spectracom recommends selecting a timeout interval of 10 to 15 minutes.

9189 – v2.3.1 Spectracom Corporation

2.3 HTTPS Certificate 20-Year Life

The HTTPS Certificate Creation Web UI page has been changed to indicate required parameters (with a red asterisk). Refer to the Security tab on the System Setup page.

The default Spectracom HTTPS Web Server Certificate is now 20 years. The new default Certificate life is therefore 7300 days (20 years, in days) and appears on the page as:

* Self Signed Certificate Expiration (Days):

7300

Spectracom Corporation 9189 – v2.3.1

2.4 Modem

Modem functionality has been improved in software version 2.3.1. ITU-R TF583.4 format is now supported. Support has also been added for the two most commonly used baud rates (1200 and 9600 baud) for ITU-R and ACTS formats. NetClocks running software version 2.3.0 require the user to reboot the unit when switching from Console to Modem mode. In software version 2.3.1, it is no longer necessary to reboot when switching from one mode to the other.

The user may select the Baud Rate or the Setup Port mode as shown in the following sections.

The baud rates 1200 and 9600 are supported because they are the most commonly used baud rates for ITU-R and ACTS formats worldwide. ITU-R format typically uses

1200 baud, while ACTS format typically uses 9600 baud.

2.4.2 Setup Serial Port Mode

To switch from Serial Console Port mode, select Modem mode (Figure 2-4). Once the

Modem mode is selected, click Modem Dial Out (Figure 2-5). This displays all the modem tabs.

2.4.3 Modem Command Line Commands

New modem line commands have been added to facilitate user operation and debugging of modem features. This supports customers in the field should there be issues concerning other dial-up time references.

The provided modem commands are:

mdo help mdo help – Used to get detailed information for modem commands

mdo avg mdo avg [on|off] [#|auto] – Set the averaging behavior of the modem

mdo log mdo log [debug|normal] – Set logging mode

mdo stat mdo stat [reset] – View or reset the modem statistics

mdo delaycomp mdo delaycomp [spring|itur] [on|off] – Enable/disable delay compensation

mdo mode mdo mode [console|modem] [1200|9600] – Set port mode and optionally change baud rate

mdo dialnow mdo dialnow [test] – Dial out immediately

mdo baud mdo baud [1200|9600] – Set baud rate

mdo speaker mdo speaker [on|off] – Set modem speaker enable

Usage: mdo avg [on|off] [#|auto]

This command switches the averaging algorithm on and off. If averaging is turned on

(mdo avg on), the number of points to average must be specified. If the number of points is specified as auto, the unit will choose the appropriate number. If no parameter is specified, the current state will be printed.

NOTE: By default, averaging is NOT used. Averaging is recommended only after a few successful dial-outs have been performed.

This command allows the user to turn on logging of call data and state to debug files for use in providing feedback to Spectracom when testing with unsupported ACTS or ITU-R time references. The call data files are named call#.log and are found in the logs directory.

NOTE: Do not leave this mode switched on, as the number of log files increases with each call. Switch it on as directed by Spectracom if you are testing a new dialup time service.

Enter mdo log debug to switch the log on. Enter mdo log normal to switch the log off.

When detailed logging is enabled, every message from the modem is printed to a file.

Remember that this mode should be used only for debugging, as files will accumulate.

2-8

9189 v2.3.0 to v2.3.1 Addendum

Spectracom Corporation 9189 – v2.3.1

This command allows the user to view or reset modem statistics. Enter mdo stat to print the statistics to the console. Enter mdo stat reset to reset the statistics.

This command skips the delay compensation step in ACTS and ITU-R protocols. This is required in the UK when using the free ITU-R NPL format (only the pay-for-use format supports delay compensation). Skipping the delay compensation may be useful in debugging or synchronizing to untested ACTS or ITU-R protocols. If the modem indicates a No Sync error when calling and connecting, try disabling delay compensation. synchronization.

Enter mdo delaycomp spring on or mdo delaycomp itur on to enable delay compensation. Enter mdo delaycomp spring off or mdo delaycomp itur off to disable delay compensation.

This command sets the console mode and, optionally, changes the baud rate. Enter

mdo mode console or mdo mode modem to switch between console and modem modes. Enter mdo mode modem 1200 or mdo mode modem 9600 to set the baud rate.

This command dials out the modem. Enter mdo dialnow to dial out immediately.

This command sets the baud rate.

NOTE: ITU-R protocols typically use 1200 baud, while ACTS protocols typically use

9600 baud. NIST ACTS may support either, but 9600 baud is recommended.

Entering this command switches the modem speaker on and off. Enter mdo speaker

on to enable the speaker and mdo speaker off to disable it.

9189 – v2.3.1 Spectracom Corporation

2.5 NTP

The NTP Daemon has been extended to allow the user to define the Reference

Identifier string. A Reference Identifier is a 4-byte field in the NTP packets indicating, in either numerical or ASCII format, the time source used by the NetClock. This field contains the Time Identifier, such as GPS, STCI (Serial Time Code Input), or Modem

Format (ITUR, PTB, SP [SPRING], NPL etc.).

The user can set the Reference Identifier to indicate the actual time source, such as

WWVB for a 9188 NetClock using the Serial Time Code Interface (STCI) to connect to a

NetClock/2 or some other WWVB receiver. The user may also use the 4-byte field as an abbreviation for the location of the NetClock, such as NYC, CHI, BOS, etc. Refer to

Figure 2-6.

Figure 2-6: Reference Identifier Field

Spectracom provides a means to set a Reference Identifier for the primary time sources, such as GPS, Serial Time Code Input, or User Defined. A means to define the

2-10

9189 v2.3.0 to v2.3.1 Addendum

Spectracom Corporation 9189 – v2.3.1

Modem Reference Identifier separately is also provided for NetClocks that include a

Modem as a backup time source (Figure 2-6).

2.5.1 NTP Command Line

The NTP Daemon also supports new commands for software version 2.3.1:

ntp refsrc ntp refsrc [primary|modem] [on|off] [‘4-character-string] – Sets NTP reference source

ntp timeout ntp timeout [seconds] – Used to set timeout for remote access tool

This command allows the user to set the primary and modem user-defined reference identifiers. Input this as ntp refsrc [primary|modem] [on|off] ['4-character-string] with the appropriate entries.

This command allows the user to set the time difference allowed between the remote

Network Access Tool and the NetClock. This is a security feature avoiding replay attacks. Enter ntp timeout [seconds] to set the value.

2.6 System Time

The System Time Tab found on the System Setup web page allows the user to view the current time on the unit using UTC or a Local Clock defined by the user. This page also allows the user to set (manually) the system time. The page has been modified for version 2.3.1 software to include two additional check boxes. The “Allow user to set time using SNMP or Web UI” checkbox allows user inputs from SNMP or this Web UI to set the system time manually. If the checkbox is NOT checked, users may not manually input time. Refer to Figure 2-7.

NOTE: When a user sets the time manually, the serial time code messages from the unit and the NTP packets will indicate that the NetClock is NOT synchronized.

Setting the time manually means the unit is NOT traceable to UTC. When entering time manually, you MUST use UTC time. If you enter local time (or a time from any other time zone), the time will be misinterpreted as UTC.
