The TimeSource 3100 is a Primary Reference Source (PRS) that receives and processes signals from GPS satellites, and outputs Stratum 1 synchronization signals traceable to UTC.

TimeSource 3100 applications include synchronization for central offices, radio base stations, transmission nodes, and other instances where a primary reference source can improve the performance of telephony network facilities.

The TimeSource 3100 creates timing outputs by ensembling signals from several sources.

The sources include GPS signals, an onboard local oscillator, and optional E1 or analog and remote oscillator signals. Timing outputs created from the ensemble are composed of the most stable and least noisy parts of each input. Synchronization outputs are delivered in a framed, all-ones, E1 or 2.048 MHz analog signal, a 1 pps signal, T1 signals (optional), and time of day (TOD) signals.

The TimeSource 3100 minimizes timing impairments, such as jitter and wander, that are created by network and transmission systems. The synchronization timing is traceable to the

GPS, which provides the highest level of synchronization for telephony networks. The

TimeSource 3100 with its GPS input is a stand-alone office PRS. With the optional inputs ensembled, overall system performance is improved, and holdover is extended if GPS signals become disrupted.

Global Positioning System

S S S S S S S S S S S S S S S S S S

S

The United States Government developed the GPS navigation system. It is a satellite-based, radio navigation aid designed to provide global, all-weather, precise navigation and timing capability to users 24 hours a day.

The satellites, circling the earth at approximately 20.197 km, are arranged in 6 orbits with 4 operational satellites in each orbit. Each satellite has an orbital period of approximately 12 hours. This configuration assures that a minimum of 4 satellites, and as many as 12, are in view anywhere in the world at all times.

2

The TimeSource 3100 tracks all satellites within its field of view. The performance of each tracked satellite is observed and compared to the others, and available for use in the timing solution. A satellite with unacceptable performance data is dropped from the timing solution.

Overview

Figure 3 shows the main functions of the TimeSource 3100. The center of the TimeSource

3100 is the Ensemble Timing Generator, which uses the BesTime algorithm to analyze the phase and frequency relationships, individually and collectively, of the timing sources. Each type of timing source has a particular characteristic that gives it an advantage over other

sources, as listed in Table A.

2

The BesTime algorithm uses the best characteristic of each source to produce an output signal with greater overall accuracy and stability than any single source. The contribution of a source is based on its deviation from the weighted average of all the sources. The more accurate a source, the more weight it has in the final output. Every source is under constant evaluation and its contribution subject to periodic adjustment. The output is essentially the best performance of the best source.

Antenna

S S S S S S S S S S S S S S S S S S S S S S S S S S S S S

S

The antenna housing includes a volute antenna, GPS receiver, amplifier, and intermediatefrequency (IF) downconverter.

The GPS Receiver extracts a clock signal from the GPS satellite signals. The receiver can process the signals from all satellites in view, while simultaneously using the Earth location of the receiver and other factors to determine an accurate clock signal.

An amplifier in the antenna provides 23 dB of signal gain.

2

A downconverter converts the L-band GPS signal to IF for long-distance transport on the coaxial antenna cable. The antenna cable provides 125 mA power from the shelf to the antenna, and transports GPS satellite IF signals from the antenna to the shelf.

IF Interface

3

An IF interface accepts the signals from the antenna, and provides the clock information to the BesTime Ensemble Timing Generator.

Local Oscillator

A digitally controlled, oven-controlled crystal oscillator (OCXO) develops a highly stable local oscillator signal, independent of factors that exist outside the shelf. This signal is sent to the BesTime Ensemble Timing Generator.

S S S S S S S S S S S S S S S S S S S S S S S S S

A clock extractor circuit extracts a timing signal from each external reference source

(External sources, other than the GPS antenna, are optional). The extracted timing signal is sent to the BesTime Ensemble Timing Generator.

Power Supply

A power converter filters and converts -48 volts dc power supplied to the shelf into the voltages required by the shelf.

NTP TimeServer

The TimeServer is a Simple Network Time Protocol (SNTP) device. The SNTP TimeServer function is provided via the TimeSource Ethernet interface and associated IP address. User software requests UTC time of day via NTP protocol. The TimeSource SNTP server responds with current UTC time. The TimeServer is compatible with the SNTP RFC-1769 format.

To enable the SNTP feature, a password must be entered using the ED-EQPT TL1 command. If a user makes a fourth attempt of an incorrect password entry, the TimeServer will lock out the user for 1 hour.

Network Time Protocol Password Activation

Use of the Simple Network Time Protocol (SNTP) feature requires activation with a password. Activation is accomplished through receipt of a Network Time Protocol

Activation Certificate from Symmetricom. This certificate contains the unit purchase order number, unit model number, unit activation date, unit serial number, and unit activation key.

The unit activation key is the password that enables the SNTP feature. To activate the SNTP feature, enter the TL l command printed on the activation certificate. Once activated, this feature will be permanently enabled. To order the SNTP feature, contact the local

Symmetricom sales representative.

BesTime Ensemble Timing Generator

Clock signals from the GPS antenna (via the IF interface), the local oscillator, the optional external sources (E1 span lines and remote oscillators) are used as sources by the BesTime algorithms in the BesTime Ensemble Timing Generator. The signals are analyzed for MTIE,

TDEV, and other phase and frequency characteristics.

The BesTime Ensemble Timing Generator uses mathematical models to analyze each clock.

The ensemble algorithms use the comparisons and analyses to generate a highly stable timing signal, which uses the best qualities of all inputs.

TimeSource 3100 has six Ethernet ports to carry TL1 commands, responses, and autonomous messages between the TimeSource 3100 and an external terminal, or an

Element Manager. The user can configure the IP address, subnet mask, and gateway address for the Ethernet ports.

Four ports (5001, 5002, 5003, and 5004) are configured to act as though a serial-port communication terminal were connected to them. These ports communicate TL1 commands, responses and autonomous messages.

2

Two additional ports communicate with Element Managers, which may have NMS, OSMF, or similar software. An Element Manager establishes a connection with one port (5551) for

TL1 commands and responses. Another port (5550) establishes a connection to an Element

Manager, sends autonomous messages, and closes the connection when finished.

Passthrough

3

The Passthrough feature of the TimeSource 3100 allows the unit to front a DCD product to provide one management interface for a user site. Passthrough allows a user to do the following:

• Provide a no download exclusion for the Passthrough port

• COM 1 or COM2 is connected to the DCD product

• The user port can be any unused port, including the Ethernet port

• Messages can pass from a user to the DCD product and from the DCD product to a user through the TimeSource 3100

5

TimeSource 3100 passes any TID not its own through to the DCD product. In the reverse direction, all commands received from the DCD product are passed through to the user.

Note:

The TID of the TL1 command must be the SID of MIS.

• DCD is fully managed except for firmware download.

Alarm Programmability

New releases of TimeSource (1.05.03 and higher) allows the user to provision the alarm escalation parameters that were hardcoded in the previous releases of TS3100.hex. The defaults for this release remain the same as were previously hardcoded. This feature can be used to set the programmability for such alarms as GPS, HOLDOVER, SPAN-X, and RO-X.

The TS3100 alarms can be programmed for GPS and HOLDOVER types of events. The

SPAN-X alarms can be programmed for AIS, ERROR, and LOS types of events. The RO-X alarms can be programmed for ERROR and LOS types of events.

The user can set the parameters for SEVERITY1 and SERAFF1 which initially come into effect when the condition is detected. The user can also set the parameters for SEVERITY2 and SERAFF2 which come into effect after TIME (another user programmable parameter).

Startup

When the TimeSource starts up, the CRIT lamp lights. The CRIT lamp remains on for approximately 50 seconds to 60 seconds and then shuts off.

During startup, the TimeSource performs several self-tests to verify the integrity of the hardware and software. Neither communication nor outputs are possible at this time, and the

CRIT lamp is switched on. Once the self-tests are done, a connection to the system can be made and the events viewed.

Two events are initially provided. These events are:

• “Power Up Restart”

• “Settling Period”

S

In the “Power Up Restart” event, which lasts for approximately 2 minutes, the system does additional checks and starts all the various tasks within the system.

The “Settling Period” event is an informational message that lasts until the TimeSource’s

BesTime engine reaches the highest possible stable point. The time taken to reach this point depends on satellite availability, type of oscillator, ambient temperature, etc. and may take up to 20 hours to clear. Since “Settling Period” is independent of the quality of the output and is the normal behavior of the system, it is generated as an event rather than an alarm. If

“Settling Period” is not cleared after 24 hours, another “Settling Period” event is generated as a marker. This is still Non-Service-Affecting.

2

As soon as the “Power Up Restart” message is cleared, the “BT3 Warm-up” event is generated. This is also an informational message that lasts till the time it takes the system to acquire the satellites, warm up the oscillator, and start giving out valid outputs. It may take up to 2 hours for the message to clear, but typically takes approximately 40 minutes. During the “BT3 Warm-up” time, the outputs will generally be squelched. If the outputs are enabled using the TL1 command

1 oscillator within 2 hours, the event escalates into a Non Service Affecting Minor alarm.

Once the warm up is complete, the system generates valid outputs and the event is cleared.

Bridging/Holdover Behavior

In the TimeSource 3100, alarms are designed with a built-in hysteresis. This means that an alarm is not announced as soon as some error condition is detected. There is a preintegration time during which the error must persist in order for the alarm to be announced.

On the flip side, the error must be clear for a certain time for an alarm condition to be cleared. This ensures that intermittent conditions are not flagged unnecessarily.

installation of the antenna. This is particularly true with wall and, especially, window antenna installations. The TimeSource 3600 has been designed to work around this situation.

The TimeSource 3100 enters “Bridging” mode when all satellite locks are lost. There is no

TL1 annunciation that the system has entered “Bridging” mode. This is “Non Service

Affecting” and the outputs are not affected. The system runs off its internal oscillator and the outputs are kept within the G.811 PRS mask by the BesTime engine.

When “Bridging” mode persists for more than 30 minutes, the system enters “Holdover” mode and a “Holdover” event is generated. This may or may not affect the outputs depending on the alarm integration parameters that can be set by the user.

The system allows the user to set various parameters for GPS error, Holdover error, and

SPAN error conditions. These parameters are:

• Initial Severity

• Initial Service Affecting state

• Integration Time

• Final Severity

• Final Service Affecting state

The system also allows the user to set a parameter to define how outputs should behave in an alarm condition. Outputs can be set to AIS, Squelch, or SSM on an alarm. Outputs can also be set to ignore alarm conditions.

When the “Holdover” event is announced, it is announced with the Initial Severity and

Initial Service Affecting state. If the “Holdover” event persists for the length of the

Integration Time, the alarm is escalated to the Final Severity and Final Service Affecting state.

The “Holdover” event/alarm is cleared when the satellites are visible again.

26

Time Figure of Merit

Time Figure of Merit (TFOM) is a moving 24 hour measurement reported in nanosecond

(ns) against an ideal model. TFOM has a frequency component used to measure GPS wander caused by multipath and a time loop component used to measure long term oscillator wander.

The TFOM alarm threshold is set to 500 ns and is not user configurable. A TFOM below

500 ns indicates a stable clock well within PRS output performance specifications. A TFOM between 500 ns and 800 ns is an early warning of a clock becoming unstable and in danger of going out of PRS specification. When the TFOM exceeds 800 ns, the clock is no longer meeting the stratum 1 MTIE mask.

TFOM is most useful for installations where the antenna has a limited view to the sky. This is defined as any installation where fewer than 4 satellites are in view for greater than 1 hour per day on average. This is typical for installations where the antenna is mounted in a window or on an outside wall of a building, but can also include rooftop installations with partial sky view blockage. TFOM’s primary use is to help troubleshoot multipath issues associated with antenna placement and incorrect latitude, longitude, and/or altitude

(location) data entry.

Installations with full view to the sky see 4 satellites 23+ hours a day, seven days a week. It is relatively easy to filter out multipath signals using multiple satellites and simple voting schemes. In addition, rooftop antennas are mounted vertically and all signals below the horizon are obvious multipath interference and can be masked out of the system. With 4

S

satellites in view, the GPS timing receiver will provide an error-free lock on its location through an automatic survey function.

With wall/window installations, voting schemes become less effective as the number of satellites in view drop. Also, wall/window antennas are mounted horizontally and are prone to seeing multipath signals reflected off nearby structures and the ground. Wall/window installations also require the manual input of location data, creating the potential for errors and the need to detect these errors.

The TimeSource has unique algorithms to account for, and defeat, the added multipath

2 installations. Large amounts of multipath or major errors in location data entry are easier to identify and are detected over a relatively short period of time. These short-term errors are normally reported via the TimeSource tracking success rate parameter.

Small amounts of multipath or minor errors in location data entry are difficult to identify because they mimic a true signal or an expected satellite behavior pattern. Single satellite

3 out. TFOM tracks and reports these long-term errors.

At time of installation, marginal or unacceptable TFOM readings can indicate the need to adjust the antenna placement, the mask angle, and/or the location data. Relatively small changes in the antenna placement can improve the ability of the system to see satellites and therefore improve performance. The mask angle can be adjusted to block out lower elevation portions of the sky if there is good visibility at higher elevations, thereby reducing multipath. Correct location data is very helpful in identifying and tracking satellites.

In addition, a clock may be stable for many weeks, months, or years but could degrade because of changes in its environment. TFOM is useful in detecting these infrequent subtle changes including:

• Maturing foliage or seasonal foliage changes

• Installation of new transmitters nearby (i.e. wireless base station)

• New building construction

• Variations in the day-to-day temperature of the CO

Determine the shelf location.

Determine the best location for mounting the antenna (less than 305 m of cable from the shelf). Use the guidelines and considerations in the Antenna

Location Guidelines section.

Determine the location of the grounding point for the lightning suppressor, then determine the location of the lightning suppressor. The cable length between the lightning suppressor and the grounding point must be less than

4.6 m. If the grounding point is inside the building, the cable length between the grounding point and the cable entry must be less than 15 m. Valid lightning suppressor grounding points are as follows:

• Valid roof ring ground system (usually for roof-mounted lightning suppressors)

• Structural steel of building (for interior-mounted or exterior mounted lightning suppressors, attach with a cad weld)

• Central Office ground plate (usually for interior-mounted lightning suppressors)

Two lengths of cable are required. Plan the cable route and measure the length of cable required between the antenna and the lightning suppressor, and between the lightning suppressor and the shelf.

Determine the two separate –48 V power sources for the shelf. If only one –

48 V power source is available, it must be cabled to both TimeSource 3100 power inputs.

• Mount the lightning suppressor within 4.6 meters of a valid, direct, low impedance, low resistance, earth ground connection point. Valid earth grounds include the roof ring ground system, building structural steel, or a Central Office ground plate. If the grounding point is inside the building, mount the suppressor within 15 meters of the cable entry into the building.

Warning:

Metal clamps that form a complete metal circle around the antenna cable or

currents, which resists current flow and hampers proper lightning protection.

Warning:

Place the lightning suppressor away from electrical devices or cabling that may induce arcing.

Note:

Keep all impedances as low as possible, otherwise the grounding scheme may be defeated.

3

• Route the ground wire as straight as possible (bends in the ground wire increase impedance at lightning frequencies), in accordance with local company practices.

• Treat all exposed connections with an electrically conductive anti-corrosion compound (Kopr-Shield or equivalent).

Warning:

Avoid small-radius turns and unnecessary turns.

Antenna Location Guidelines

S S S S S S S S S S S S S S S S S

The ideal antenna location provides a clear, unobstructed view of the sky from the zenith to the horizon line, and 360 degrees around the horizon.

A compromise often must be made between location and satellite field of view. The smaller the field of view, the fewer satellites that can be used in the timing solution for GPS derived time.

Signals closer to the horizon are often subject to multipath effects, which degrade the timing solution. The TimeSource 3100 can be set to ignore, or mask, all signals from the horizon to

a chosen angle of elevation (mask angle). (See Figure 6.)

Due to the geometry of the GPS satellite orbits, more satellites are visible in the direction of the equator than the poles. If possible, place the antenna so that the antenna has a clear view toward the equator (toward the south in the northern hemisphere, or toward the north in the southern hemisphere). Up to 60 degrees of arc, centered at the pole, may be blocked with little effect in the temperate latitudes. This note is less applicable in latitudes nearer the equator.

The total of obstructions above the mask angle should not obscure more than 25 percent of

the total field of view (90 degrees of azimuth) (Figure 7).

Notes:

1.

5 mount the antenna more than 1 meter away from the tower, and far below the interference of the antennas at the top of the tower. Tower mounting is the least desirable location because of the potential for severe multipath, and difficulty in troubleshooting and maintenance.

2.

Place the antenna high enough that the roof structure and tree are below the mask angle, and the water tower does not block a large portion of the sky.

No single obstruction should block a large portion (45 degrees of azimuth) of the view.

The most important obstructions are within 400 meters of the antenna. Obstructions may include, but are not limited to, towers, buildings, other construction, trees, and high-voltage power lines.

Attempt to avoid locating the antenna within 30 degrees azimuth of the transmission direction of any transmitting antenna in the area, even if the transmitting antenna operates at a different frequency. A transmitting antenna may cause the GPS antenna to become overloaded and reduce its reception capabilities.

The minimum horizontal distance from other receiving antennas is 1 meter.

To reduce multipath signal distortions, the minimum horizontal distance from vertical reflective structures (e.g. heating ducts, equipment housings, etc.) is twice the height of the

structure, and no less than 3 meters (see Figure 8).

Do not locate the antenna underneath high power lines. If this cannot be avoided, ensure the antenna is placed at least twice as far from the power line as the power line is high (to avoid danger to personnel or multipath effects).

Antenna Cable Choices

S S S S S S S S S S S S S S S S S S S S S S

The antenna assembly uses the same coaxial cable for power and antenna signals. The length of cable is determined by circumstances of the installation and site.

Two cables are required: one to connect the antenna to the lightning suppressor, and another to connect the lightning suppressor to the TimeSource 3100 Shelf.

Symmetricom offers RG-59/U plenum-rated coaxial cable (0.812 mm [20 AWG], 75 ohm coaxial) with male TNC connectors attached, in the following lengths:

• 3 m cable (060-72010-01)

• 6 m cable (060-72010-02)

• 15 m cable (060-72010-05)

• 30 m cable (060-72010-10)

Ensure the frame ground wires are long enough to reach from the shelf connector panel to the frame ground connection. Use one 1.47 mm (16 AWG) green insulated wire to connect the FRM terminal of power terminal block TB1 to the frame ground, and use another 1.47 mm (16 AWG) green insulated wire to connect the FRM terminal of TB2 to frame ground.

Make the ground connection, following one of the methods described below, depending on whether a ground rod is installed:

With ground rod:

Solder the connection to the 4.115 mm (6 AWG) frame ground rod that is run vertically on each side of the rack, if provided. Two methods are acceptable:

• Crimp an appropriate-size spade lug to the 1.47 mm (16 AWG) wire, bend the lug around the frame ground rod, and solder.

• Strip enough insulation from the 1.47 mm (16 AWG) wire to permit three complete turns around the frame ground rod, and solder.

Note:

When soldering, use a 25 watt soldering iron to ensure the frame ground rod is heated sufficiently to prevent a cold solder connection

.

Module for ESCIU Ports

S S S S S S S S S S S S S S S S S S S S S S

The ESCIU ports (Figure 21) have a different function than the synchronization outputs.

Synchronization outputs provide external reference clock signals for network elements.

ESCIU ports carry El traffic, and directly synchronize the El bitstream.The ESCIU module can synchronize 2 spans in one direction. The return direction passes through as it is.

The ESCIU ports can connect at the digital distribution frame (DDF). The network elements receiving the ESCIU output signal must be able to receive El signals that conform to CCITT

G.703 paragraph 6 specifications.

A bypass relay directs the E1 traffic around the ESCIU circuits to maintain continuity on the spans if a fault occurs.

Install the battery source fuse in the rack fuse bay that supplies power to the TimeSource

3100. The TimeSource 3100 enters its warm-up mode when power is applied. During the warm-up period, the following conditions exist:

• Status GPS lamp is green

• Status SYS lamp is off

• E1 outputs are squelched, sending AIS (factory setting), or sending an SSM message, as specified in the ED-EQPT command

• Optional eight T1 outputs (if equipped) are squelched, sending AIS (factory setting), or sending an SSM message, as specified in the ED-EQPT command

• Optional four IRIG-B outputs (if equipped) are squelched

• 10 MHz and 1 pps outputs are on (unreliable while Status SYS lamp is off)

• TOD output is not enabled (factory setting)

Notes:

Procedure

If not using an Element Manager, skip to Step 29. If not using a separate port to send autonomous messages to an Element Manager, skip to Step 28. Use the Edit Equipment command to set the IP address and port address of the Element Manager. Port 5550 connects to this address when the TimeSource 3100 develops a TL1 autonomous message, sends any messages, and closes the connection. An alternate Element Manager may be set up in case port 5550 cannot make a connection to the primary Element

Procedure

An Element Manager connects to port 5551 for TL1 command and response messages.

The following values for port 5551 are set at the factory and appear at reset:

COMPRI=ALW1 (normal communication, including autonomous messages)

MONMSG=INH (monitors only the current port for messages)

KEEPALIVE=0 (does not send a COMPLD message to keep connection open)

ENDOFTEXT=0 (does not include an end-of-text code with a TL1 message) 2 inhibits echo (b=INH)

AUTOLOGOFF=20 (does not log off the user during inactivity)

SWCONTROL=INH (uses no flow control)

If these values require change, use the Edit Communication command to set communications parameters for TL1 communications.

ED-COM::COM-5551:<ctag>:::[MONMSG=b[,]][KEEPALIVE=c[,]]

3

MONMSG=b= Monitors messages on all ports (b = ALW), or current port (b = INH)

KEEPALIVE=c=Inactive minutes until the unit sends a COMPLD message to keep the connection from being closed (c = 0 to 255)

ENDOFTEXT=d= Hex code added to responses before semicolon (d = 0 (disabled) to 9F)

ECHO=b=Echoes characters received so they appear on the user's screen as typed (b =

ALW), or inhibits echo (b = INH)

COMPRI=e=Sets the communication port capabilities as follows:

ALW0 = normal communication, no autonomous messages

ALW1 = normal communication, autonomous messages

ALW2 = autonomous messages received, logged on or not

INH = closes connection and keeps port from use (command must go to another port) (if the port is in use, this command also logs off the user)

AUTOLOGOFF=c=Inactive minutes until the unit logs off the user, keeping the connection open (c = 0 to 255)

= INH)

If not using ESCIU ports, skip to Step 31. Use the Edit Equipment command to specify how the ESCIU performs during holdover:

ED-EQPT::TS3100:<ctag>:::BYPASS=a; a=E1 traffic bypasses the ESCIU circuitry (a=ALW) or continues to be synchronized during holdover (a=INH)

Use the Edit Equipment command to specify how the ESCIU performs with a Loss-of-

Signal (LOS) alarm on the incoming span:

ED-EQPT::OPT-a:<ctag>::ALMOUT=b; a= Directs this command to ESCIU span 1 (a=1) or span 2 (a=2) b= If LOS is detected on the incoming span, the ESCIU passes AIS downstream (b=AIS) or passes the LOS downstream (b=PASSTHRU)

Procedure

If the results of Step 19 indicate the antenna cable delay and elevation mask set are as desired, skip to Step 33. Use the Edit Equipment command to set the length of cable between the antenna and the TimeSource 3100 Shelf. This number should have been recorded during installation. Use the same command to set the antenna elevation mask angle.

ED-EQPT::GPS:<ctag>:::ANTCBLDLY=x,ANTELEVMASK=y; x = antenna cable delay in meters (x = 0 to 330) y = antenna elevation mask angle in degrees (y = 0 to 45) (see note below)

Note:

The antenna elevation mask is that portion of the sky from which the TimeSource

3100 masks out satellite signals, measured from the horizon to the desired angle of elevation. For example, if the sky is obstructed below 20° elevation, signals received from below that elevation may have reflections or other anomalies. Masking those signals may allow the receiver to acquire GPS signals more quickly and accurately. Factory setting is

10.

If not using the TOD output, skip to Step 33. Use the Edit Equipment command to set the

TOD output.

ED-EQPT::TS3100:<ctag>:::TOD=y; y = TOD format (y = Cisco or NTP4)

Use the Edit Equipment command to allow or inhibit alarm conditioning on the outputs.

Inhibiting the alarm conditioning forces the TimeSource 3100 to continue to output valid timing signals while in alarm. This may be useful when testing, troubleshooting, or in installations where the outputs generated by the TimeSource 3100 may be better than the alternative (for example, offices without additional holdover clocks in a distribution shelf).

ED-EQPT::TS3100:<ctag>:::ALMCOND=y; y = alarm conditioning of the outputs (y = ALW or INH)

Use the Copy Memory command to copy the database from volatile to nonvolatile memory within the TimeSource 3100.

CPY-MEM:[tid]:TS3100:<ctag>::WKG,,AUX:DATA;

Note:

Although the database is automatically copied to nonvolatile memory once per hour, it is recommended that the Copy Memory command be executed each time the database is changed.

Uppercase letters in a command designate parameter values which must be entered as shown. Lowercase letters in a command are the parameter name, and the specific values that must be entered for the parameter. The Parameters section of this chapter describes the parameters and the values where a value is the same for all parameters. Parameter values for a particular command are listed with the command. The system accepts either uppercase, lowercase, or a mixture of both, but upper and lower case cannot be mixed within a parameter block.

The following symbols are used in the input and response messages:

[ ] encloses an optional parameter

|

{ } encloses a group of parameters, at least one of which must be entered separates alternatives in a group of parameters, at least one of which must be entered

^ indicates a space (used in the description of the response format, but not used in the command responses) separates command code fields separates parameter blocks separates parameters within a block terminates a command, and causes execution

Command Format

S S S S S S S S S S S S S S S S S S S S S S S S S S

A command consists of a command code of up to three fields separated by hyphens,

followed by parameter blocks separated by colons. Figure 27 shows the command format.

Parameter blocks consist of one or more parameters separated by commas.

Parameter blocks may be null (contain no parameters), or contain one or more parameters.

Two colons occur next to each other if a parameter block is null.

1 to each other if a parameter is null.

Entering a semicolon at the end of the command indicates that the command statement is completed to the interpreter, and executes the command.

When a command is received and processed, a response is returned. All responses include a source identifier (<sid>), the date, the time, an M to indicate that it is a response to a command, and the correlation tag (<ctag>) that was entered with the command.

Figure 28 shows the completed response format. COMPLD indicates that the command was

completed without error.

Figure 29 shows the denied response format. DENY indicates that the command was denied

due to an error. The <errcde> parameter indicates the corresponding error type, or cause of the error.

This command copies a software program from an external computer to the TimeSource

3100, or copies the system database to nonvolatile memory.

Notes:

1.

Clear any existing alarms before using this command.

2.

The database is automatically copied to nonvolatile memory once per hour. However, if power to the TimeSource 3100 is interrupted before the automatic copying occurs, changes made since the last automatic copy will be lost. To avoid the possibility of losing database changes, the Copy Memory command may be used to copy database changes to nonvolatile memory after any changes are made.

To copy a program from an external computer to nonvolatile memory within the

TimeSource 3100, the command format is:

Ethernet ports 5001, 5002, 5003, and 5004 are set up to act as serial communication ports, so that a terminal program on a computer connected to these ports can communicate effectively.

2.

Ethernet port 5551 is set up to allow an element manager to connect with it for TL1 commands and responses. TL1 autonomous messages are sent through port 5550, which connects to an element manager to send one or a group of autonomous messages, then disconnects. Port 5550 is not to be reconfigured.

3 a = UTC

(Note 2)

Uses Universal Coordinated Time from

GPS (cannot be set by TL1 command) a = LOCAL Uses local time for hours, UTC for minutes and seconds

Notes:

1.

The <time> value can only be entered when MODE=LOCAL, or in the same command as MODE=LOCAL, otherwise the command is denied. A successful command with

<time> changes the display of time to conform to the nearest 30 minutes, relative to UTC.

5 actually set the clock to 18:42:10, because 18:42:10 is the closest 30 minute jump, relative to UTC, from 18:50:30. This is done to accommodate 30-minute time zones and still keep the local time accurate to UTC.

2.

If a command includes MODE=UTC, and the GPS signal is not present, the command is denied.

The date/time stamp behavior is as follows:

• During warm-up:

The date/time displayed starts from 1970 and increments from there. If the ED-

DAT command is used to set the time in local mode, the time is changed as specified in the command.

• After warm-up:

If the ED-DAT command has not been used to set the local mode time, then

UTC date and time are displayed.

If the ED-DAT command has been used to set the local mode time, then it is changed in the manner described as follows.

The date given in the ED-DAT command is retained. The local hours, minutes, and seconds are set to the nearest 30-minute divisible difference from UTC. A few examples will help to clarify.

> Example 1. UTC time= 01:00:00. Local time= 18:01:10 will set the local time to 18:00:00.

> Example 2. UTC time= 01:00:00. Local time= 18:25:30 will set the local time to 18:30:00.

> Example 3. UTC time= 01:12:10. Local time= 18:50:30 will set the local time to 18:42:10.

During Holdover Event

The date/time continues to increment normally.

• During Holdover Alarm

- The date/time continues to increment normally.

Example to set date without changing time or mode:

When setting alarm integration time (SEVERITY or SERAFF), the type of alarm

(HOLDOVER, GPS, LOS, AIS, or ERROR) has to be specified. For example, ED-

EQPT::TS3100:CTAG::: ALARM=HOLDOVER, TIME=72-00, SEVERITY1=EV,

SERAFF1=NSA, SEVERITY2=MJ, SERAFF2=SA; will generate a holdover event as soon as the condition is detected with an NSA flag. Once this condition has existed for

72 hours, TS3100 will generate a major alarm with an SA flag. These parameters can then be verified using the RTRV-EQPT command.

5.

If the dbinit jumper is changed, the NTP password has to be re-entered.

6.

A remote oscillator must have been put into service before using the ENT-EQPT command before setting the ENSEMBLER parameter.

7.

A span must have been put into service using the ENT-EQPT command before setting the

ENSEMBLER and SSM parameters.

8.

The span must be put into service using the ENT-EQPT command before using this parameter.

2.

When setting alarm integration time (SEVERITY or SERAFF), the type of alarm

(HOLDOVER, GPS, LOS, AIS, or ERROR) has to be specified. For example, ED-

EQPT::TS3100:CTAG::: ALARM=HOLDOVER, TIME=72-00, SEVERITY1=EV,

SERAFF1=NSA, SEVERITY2=MJ, SERAFF2=SA; will generate a holdover event as soon as the condition is detected with an NSA flag. Once this condition has existed for

72 hours, TS3100 will generate a major alarm with an SA flag. These parameters can then be verified using the RTRV-EQPT command.

1. SNTP packet will indicate Stratum 2 in NTP packet header if GPS is out of lock.

2

2. The “ref id” field changes from GPS to at Stratum 1 to the IP address at Stratum 2 to signify that the reference is the TimeSource clock itself.

Password Activated:

3. SNTP packet will indicate “clock not synchronized” integration time.
