Chapter 1 Overview of the TimeSource 3600

Overview

Overview

The TimeSource 3600 is a Primary Reference Source (PRS) that receives and processes signals from GPS satellites, and outputs Stratum 1 synchronization signals traceable to UTC. TimeSource 3600 applications include synchronization for central offices, wireless base stations, transmission nodes, and other cases where a primary reference source can improve the performance of a telecommunications network infrastructure.

The TimeSource 3600 is also ideal for installation in environments where receiving

GPS signals is difficult. Examples of environments hostile to GPS signals include urban canyons which have a very limited view of the sky because of blockage from nearby buildings, and high interference zones where GPS signals are jammed by competing over-the-air signals.

The TimeSource 3600 creates timing outputs by ensembling signals from several sources. The sources include GPS signals, an onboard rubidium local oscillator, and optional E1 or analog signals. Timing outputs created from the ensemble are composed of the most stable and least noisy parts of each input. The performance of the E1 sources can be monitored and classified using standard measures.

Synchronization outputs are delivered in a framed, all-ones, E1 format or 2.048

MHz analog signal, a 10 MHz signal, a 1 pps signal, and a choice of time of day

(TOD) formats.

The TimeSource 3600 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 3600 with its GPS input is a stand-alone office

PRS. With the optional inputs ensembled, holdover is extended if GPS signals are disrupted.

Global Positioning System

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.

The TimeSource 3600 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.

TimeSource 3600 User’s Guide 097-72060-01 Revision J – June, 2007

Chapter 1 Overview of the TimeSource 3600

Physical Description

GPS antennas must have line-of-sight access to the transmitting satellites. Any structure that interferes with, or blocks, the view of the satellites disrupts the reception of the signals, and can adversely impact the timing performance of a receiver.

The TimeSource 3600 bridges frequent GPS outage periods with BesTime algorithms, an ultra-stable Rubidium local oscillator and advanced holdover technology. The technology anticipates the outages and uses BesTime-generated predictor values to optimize the performance of timing without direct satellite input.

Physical Description

The TimeSource 3600 consists of a shelf, a plug-in card, an antenna, cables, hardware, and software. Optional system configurations include eight additional E1 or analog 2.048 Mhz outputs, two E1 synchronous clock insertion unit (ESCIU) ports, four IRIG-B TOD timing outputs, or eight mixed E1/T1 outputs.

The shelf (

Figure 1-1 ) can be mounted in a 48 cm rack or an ETSI 53.5 cm rack.

One RU (4.45 cm) of air space above the TimeSource 3600 is required for proper ventilation. Other than a communications connector on the front panel, all connectors are at the connector panel.

Four types of antennas are available: roof antenna for installation outdoors, usually on a roof mechanical antenna for installation indoors, mounted on a window sill or wall for reception through a window self-adhesive antenna for installation indoors, adhered directly to a window wall antenna for installation outdoors, through a hole in the wall

Functional Description

Figure 1-6

shows the main functions of the TimeSource 3600. The center of the

TimeSource 3600 is the BesTime 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 1-1 .

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 each individual source.

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 provides signal gain.

The downconverter converts the L1-band GPS signal to IF for long-distance transport on the coaxial antenna cable. The antenna cable provides current from the shelf to the antenna, and transports GPS satellite IF signals from the antenna to the shelf.

Antenna Installation and Lightning Protection

The TimeSource 3600 standard wall antenna kits do not include lightning protectors. When the antenna is installed on the side of the building, the antenna is in the zone of protection and is protected from lightning strikes as described in the

Standard for the Installation of Lightning Protection Systems (NFPA 780), 2000 edition.

The zone of protection shall include the space not intruded by a rolling sphere having a radius of 45.72 meters (150 ft). Where the sphere is tangent to earth and resting against a strike termination device, all space in the vertical plane between the two points of contact and under the sphere shall be considered to be in the zone of protection. A zone of protection shall also be formed where such a sphere is resting on two or more strike termination devices and shall include the space between those devices (see

Figure 1-7 ). All possible placements of the sphere shall

be considered when determining the zone of protection using the rolling sphere model.

Figure 1-7.

Chapter 1 Overview of the TimeSource 3600

Functional Description

For structure heights exceeding 45.72 m (150 ft) above earth or above a lower strike termination device, the zone of protection shall be considered to be the space in the vertical plane between the points of contact and under the sphere where the sphere is resting against a vertical surface of the structure and the lower strike termination device or earth. The zone of protection shall be limited to the space above the horizontal plane of the lowest terminal unless it can be extended by further analysis, such as in rolling the sphere to be tangent to earth.

If the wall antenna is installed outside the zone of protection, Symmetricom offers an outdoor and/or indoor lightning protector kits for these installations. Refer to

Chapter 2, Engineering & Ordering, for more information on these kits.

IF Interface

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

GPS Receiver

The GPS Receiver continuously tracks up to eight satellites, using both carrier and code lock. The recovered pseudo-range measurement data is processed to determine precise time and frequency state estimates for the local oscillator. The receiver software is optimized to track and update state estimates, when as few as one satellite is in view.

Local Oscillator

A rubidium oscillator, based on a digitally controlled servo-loop, provides an ultra-stable local oscillator signal, which is sent to the BesTime Ensemble Timing

Generator.

Clock Extractors

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 circuitry.

Functional Description

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 Network Time Protocol (NTP) 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 NTP feature.

To activate the NTP feature, enter the TL1 command printed on the activation certificate. Once activated, this feature will be permanently enabled. To order the

NTP feature, contact the local Symmetricom sales representative.

BesTime Ensemble Timing Generator

Clock signals from the GPS antenna (via the IF interface), local oscillator, and optional E1 span lines are used as sources by the BesTime algorithms in the

BesTime Ensemble Timing Generator. The signals are analyzed for MDEV, 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.

E1 or Analog Outputs

The BesTime Ensemble Timing Generator provides the timing for the E1 or analog

(2.048 MHz) timing signal available at the E1 OUT A and B connectors. E1 is provided in a framed, all-ones format, which can be set to CAS, CAS4, CCS, or

CCS4 framing. 2.048 MHz is provided in accordance with G.703/10.

Functional Description

Eight Mixed E1/T1 Outputs

This feature enables a user to mix any combination of E1 and T1 outputs. A user can also use any combination of framing. For E1, CCS, CAS, CCS with CRC4, and

CAS with CRC4 can be used per G.703 table 6. For T1, D4 or ESF can be used per

ANSI T1.101. In addition, there is support for analog (2.048 MHz) per G.703 table

10 and support for synchronous status messaging (SSM) per TR-33 for E1 and T1.

Eight Additional E1 or Analog Outputs (990-72060-02 Systems

Only)

This option provides eight additional E1 or analog (2.048 MHz) outputs, available with the required option module. The module mounts in the OPTIONS I/O mountings on the connector panel. These outputs function the same as the standard E1 outputs.

TOD Output

The BesTime Ensemble Timing Generator provides the timing for the TOD timing signal available at the RJ-45 connector, which provides time code to devices compatible with NTP Type 4 or Cisco ASCII format.

IRIG-B TOD Outputs (990-72060-05 Systems Only)

This option provides four additional TOD outputs in IRIG-B format. The outputs are available at a BNC output module mounted on the OPTIONS I/O mountings on the connector panel.

The BesTime Ensemble Timing Generator provides the timing for the TOD timing signal, which provides timing code to devices compatible with IRIG-B.

1 PPS Output

The BesTime Ensemble Timing Generator provides the timing for the

1 pulse-per-second timing signal available at the 1 PPS connector, which can be used for application-specific requirements. This signal is not squelched during an alarm.

10 MHz Output

The BesTime Ensemble Timing Generator provides timing for the 10 MHz timing signal available at the 10 MHZ connector, which can be used for local cellular frequency or testing purposes. This signal is not squelched during an alarm.

Communication Ports

Three serial communication ports carry TL1 commands, responses, and autonomous messages between the TimeSource 3600 and an external terminal.

Ethernet

TimeSource 3600 has six Ethernet ports to carry TL1 commands, responses, and autonomous messages between the TimeSource 3600 and an external terminal, or an Element Manager, or both. 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.

Chapter 1 Overview of the TimeSource 3600

Functional Description

Two additional ports communicate with Element Managers, which may have NMS,

TimePictra, 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 Manger, sends autonomous messages, and closes the connection when finished.

Passthrough

The Passthrough feature of the TimeSource 3600 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:

COM1 or COM2 of the TimeSource 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 3600

The TID (SID for DCD) is used to identify commands that go to the DCD product.

The TimeSource 3600 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.

GUI interfaces to the DCD product are not supported through the Passthrough, only TL1 responses are available.

Chapter 1 Overview of the TimeSource 3600

Functional Description

Alarm Programmability

Releases of TimeSource (1.05.03 and above) allow the user to provision the alarm escalation parameters that were hardcoded in the previous releases of TS3000.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 TS3600 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 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).

The system also allows the user to set a parameter to define how outputs should behave in an alarm condition (see ALMOUT and ALMCOND settings). Outputs can be set to AIS, Squelch, or SSM when Holdover alarm severity is set to minor or major. AIS, Squelch, or SSM is not evoked if Holdover severity is set to event

(factory default for initial severity). Outputs can also be set to ignore alarm conditions.

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"

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.

097-72060-01 Revision J – June, 2007 TimeSource 3600 User’s Guide

35

Chapter 1 Overview of the TimeSource 3600

Functional Description

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.

As soon as the "Power Up Restart" message is cleared, the "BT3 Warmup" 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 Warmup" time, the outputs will generally be squelched. If the outputs are enabled using the TL1 command (ED-EQPT::

TS3600:ctag:::ALMCOND=ALW;) they may not be within the PRS mask. In case the system is not able to acquire sufficient number of satellites and/or discipline the 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 3600, 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 pre-integration 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.

During the normal working of the TimeSource 3600, it is a very common occurrence that the GPS satellites may not be visible during certain parts of the day, depending on the 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 3600 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.

36

TimeSource 3600 User’s Guide 097-72060-01 Revision J – June, 2007

Chapter 1 Overview of the TimeSource 3600

Functional Description

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 (see ALMOUT and ALMCOND settings). Outputs can be set to AIS, Squelch, or SSM when Holdover alarm severity is set to minor or major. AIS, Squelch, or SSM is not evoked if Holdover severity is set to event

(factory default for initial severity). 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.

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.

097-72060-01 Revision J – June, 2007 TimeSource 3600 User’s Guide

37

Chapter 1 Overview of the TimeSource 3600

Functional Description

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 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 complications and location data entry error possibilities of wall/window antenna 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 reception over limited periods of time complicates the ability for the internal TimeSource algorithms to filter out these ghost signals and longer periods of time are needed to sort them 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

TimeSource 3600 User’s Guide 097-72060-01 Revision J – June, 2007

Chapter 1 Overview of the TimeSource 3600

Functional Description

Success Rate

Success rate is a moving 24-hour window indicating the TimeSource's ability to lock to and use the GPS as part of the system's timing solution. This metric is reported as a percentage (%) ratio of the total good minutes that the system uses GPS in a day (maximum 1440 minutes/day). Success rate can range in value from 0% to

100%.

Success rate is determined by totaling all good minutes of satellite(s) visibility that the system is using and dividing by the total maximum possible minutes in a day.

When satellites are not being used in the solution, usually because of low satellite visibility or multipath effects, the minutes are not counted in the good minutes category.

The success rate of a rooftop antenna configuration is generally higher than a wall/window antenna configuration since rooftop installations have a better view of the sky. A wall/window installation typically may see only portions of the sky with fewer satellites.

The TFOM (Merit) metric plays a key role in the calculation of Success Rate (see

Time Figure of Merit , on page 37). When TFOM is greater than 500 ns, it is a

warning that the system clock is becoming unstable and may be going out of PRS specification. Success Rate uses this as a threshold, so when the TFOM value is equal or below 500 ns, minutes are calculated within the good minutes category.

Conversely, when the TFOM value is above 500 ns, these minutes are not considered as good minutes.

Determine the best location for mounting the antenna (less than 330 m of cable from the shelf). Use the guidelines and considerations found in

Roof Antenna

Location and Cabling Guidelines , on page 43.

If a roof-mounted antenna is installed, 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:

• Valid 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)

If a roof-mounted antenna is installed, 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.

If a window or wall-mounted antenna is installed, plan the cable route and measure the length of cable required between the antenna 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 3600 power inputs.

Roof Antenna Location and Cabling Guidelines

Warning:

To avoid serious personal injury or death, do not select an antenna location that could be an electrical or physical hazard to work persons or equipment. Avoid proximity to all high-voltage sources.

Mount in an easily maintainable location.

The ideal roof 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. With a smaller field of view, the TimeSource 3600 can use fewer satellites in the solution for GPS derived time. The TimeSource 3600 will operate with an average of one satellite in view for 40 percent of the time in a day.

Signals closer to the horizon are often subject to multipath effects, which degrade the timing solution. The TimeSource 3600 can be set to ignore, or mask, all signals

from the horizon up to a chosen angle of elevation (mask angle). (See Figure 2-1..)

Figure 2-1. Antenna Field of View

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.

Chapter 2 Engineering & Ordering

Antenna Guidelines

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 see Figure 2-2.).

Figure 2-2. Antenna Location Examples

Notes:

Place the antenna high enough on the tower that obstructions are below the mask angle; 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.

Place the antenna high enough that the roof structure and tree are below the mask angle, and the water tower does not block more than

12.5 percent 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.

44

TimeSource 3600 User’s Guide 097-72060-01 Revision J – June, 2007

Chapter 2 Engineering & Ordering

Antenna Guidelines

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 2-3.).

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 and multipath effects).

Cables must be run as straight as possible. All cables should be routed in accordance with local company practices.

Note:

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

Observe the following guidelines during the placement and installation of the cables:

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

Any opening where conduit enters the building must be waterproofed per local company practices.

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

Caution:

To prevent damage to cables, avoid small-radius turns and unnecessary turns.

Roof Antenna Earth Ground Location Guidelines

The roof ring ground system, a Central Office grounding plate, and building structural steel are examples of valid earth ground points. If the mounting plate cannot be bolted to a valid earth ground, or if the mounting plate is to be installed in a nonmetallic junction box, bolt the mounting plate to a point within 4.6 meters of the valid earth ground.

Roof Antenna Cable Choices

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.

Symmetricom offers RG-59/U plenum-rated coaxial cable (20 AWG [0.812 mm], 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)

243 m cable (060-72010-80)

305 m cable (060-72010-99)

Two cables are required: one to connect the antenna to the lightning suppressor, and another to connect the lightning suppressor to the TimeSource 3600 Shelf.

Optionally, one length of coaxial cable may be ordered, which must be cut and prepared with end-connectors at the point where the suppressor is located.

When selecting a window or wall in which to install the antenna, select the window or wall which has the maximum unobstructed view of the sky. Do not select a window or wall which has the view of the sky obstructed by trees, buildings, or towers. The smaller the field of view, the fewer the number of satellites that can be used in the timing solution for GPS derived time. The consequence of this is that the timing generator may experience holdover more often and may eventually go into alarm.

Due to the geometry of the GPS satellite orbits, more satellites are visible in the direction of the equator than the poles. If possible, select a window or wall which has a clear view toward the equator (toward the south in the northern hemisphere, or toward the north in the southern hemisphere). This guideline is less applicable in latitudes nearer the equator and more important nearer the poles.

Certain parts of the sky are blocked from view. These obstructions usually exist from the horizon line and up, for example, a building or mountain. The processor inside the GPS receiver observes every piece of the sky, whether it is blocked or not. If unproductive parts of the sky are masked from the processor’s view, the processing time is reduced, and the timing solution can be achieved more quickly.

Note:

A band of the sky from the horizon up to a point where a view of the sky begins is called a mask angle. The mask angle typically should not exceed 10 degrees (if the mask angle is set too high, too little of the sky is available to the receiver). Determine the mask angle for the selected antenna location (

Figure 2-4

) and make a note of it.

The mask angle, in degrees, will be entered during the initial setup.

Window and Wall Antenna Cable Choices

A window or wall antenna includes an attached coaxial cable terminating in a male

SMA connector. A separate cable is required to connect the IF converter to the

TimeSource 3600 shelf. Two types of plenum-rated cable are available.

The cables with longer length capabilities (060-72010-xx) are RG-59/U (20 AWG

[0.812 mm], 75 ohm coaxial) with male TNC connectors attached to each end.

Assembled cables are available 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)

61 m cable (060-72010-20)

91 m cable (060-72010-30)

152 m cable (060-72010-50)

182 m cable (060-72010-60)

243 m cable (060-72010-80)

305 m cable (060-72010-99)

The more flexible cables (060-72050-xx) are Mini RG-59/U (20 AWG [0.812 mm],

75 ohm coaxial) with male TNC connectors attached to each end. Assembled cables are available in the following lengths:

15 m cable (060-72050-05)

30 m cable (060-72050-10)

61 m cable (060-72050-20)

152 m cable (060-72050-50)

IRIG-B TOD (990-72060-05 System Only)

If you are using the IRIG-B TOD outputs (990-72060-05 TimeSource 3600 System), right-angle BNC connectors are provided to prevent small radius turns in the IRIG-B

TOD cables. The right-angle BNC connectors may be attached to the IRIG-B BNC connectors, to direct the cables from the shelf as desired.

For each IRIG-B TOD output, a user-supplied cable with BNC connectors on each end is installed between the adapter and the network elements requiring IRIG-B

TOD timing.

Shelf Considerations

RS-422–to–RS-232 TOD Converter

If you are using time-of-day (TOD), and the device receiving the time code accepts an RS-232 signal instead of an RS-422 signal (for example, a Cisco router), an

RS-422–to–RS-232 TOD Converter Kit is required (ordered separately, part number

093-72000-98).

The RS-422–to–RS-232 TOD Converter Kit consists of a mounting plate with a female RJ-45 connector, a female DB-25 connector, a TOD converter, and two screws.

Install the converter anywhere (for example, on unused space on a rack) within 305 cable meters of the TimeSource 3600 shelf, and within 15 cable meters of the device receiving the time code.

The user must supply two cables. One cable is a Category 5 four-pair RS-422 cable, 305 meter maximum, with RJ-45 connectors on each end. Route this cable between the TimeSource 3600 Shelf and the converter.

The other cable is an RS-232 data communications cable, 15 meters maximum, with a 25-pin male D-type connector and another connector determined by the device receiving the time code. Route this cable between the converter and the device receiving the time code.

Shelf Considerations

The TimeSource 3600 Shelf can be mounted in an ETSI 53.5 cm rack or a 48 cm rack. The shelf is shipped with supplied mounting ears positioned for flush mounting

on an ETSI 53.5 cm rack. Attach the mounting ears, as shown in Figure 2-5., for

flush mounting or 12.7 cm offset mounting. Attach the long side of the mounting ear to the shelf for an ETSI 53.5 cm rack, and attach the short side of the mounting ears to the shelf for a 48 cm rack. Mount the shelf in the rack according to standard company practices. Leave one RU (4.45 cm) of air space above the

TimeSource 3600 Shelf for proper ventilation. Mount the shelf in the rack according to standard company practices.

Note:

Two screws can be used in each mounting ear when the holes in the rack are spaced 4.45 cm apart.

Figure 3-15. Connector Panel Terminal Block Connections

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 terminal of power terminal block TB1 to the frame ground, and use another 1.47 mm (16 AWG) green insulated wire to connect the 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 frame ground connection to the 4.115 mm (6 AWG) frame ground rod run vertically on each side of the rack. Two methods are acceptable:

Crimp an appropriate-size spade lug (user-supplied) to the 1.47 mm (16 AWG) wire, bend the lug around the 4.115 mm (6 AWG) rod, and solder.

Strip enough insulation from the 1.47 mm (16 AWG) wire to permit three complete turns around the 4.115 mm (6 AWG) rod, and solder.

Note:

When soldering, use a 25 watt soldering iron to ensure the

4.115 mm (6 AWG) rod is heated sufficiently to prevent a cold solder connection.

Without ground rod

Crimp the supplied spade lug to the 1.47 mm (16 AWG) wire, and screw the lug to a screw hole on the rack. Remove the paint and sand the area around the screw hole to ensure proper conductivity. Coat the connection with an electrically conductive antioxidant compound, for example, Kopr-Shield spray.

Crimp the supplied spade lug to the other end of the 1.47 mm (16 AWG) wire, and connect it to the

terminals on TB1 and TB2 ( Figure 3-15 ).

Making Power Connections

Caution:

To avoid electrical shock and possible personal injury, power source protective fusing must be provided as part of the installation. This equipment is intended for installation in a restricted access location.

Caution:

To avoid damage to the system, do not apply power to the

TimeSource 3600 before instructed in this procedure. Before connecting the power cables to the TimeSource 3600, ensure the fuses are removed from the fuse panel that supplies power to the power cables.

Note:

Input power is reverse polarity protected; there are no user replaceable fuses in the TimeSource 3600.

Power connections are made on power terminal blocks TB1 and TB2. Refer to

Figure 3-14

for the location of the terminals on the shelf connector panel, and refer

to Figure 3-15 for the terminal connections.

Ensure the power wires are long enough to reach from the shelf connector panel to the office battery source connection.

Use two 1.47 mm (16 AWG) stranded wires for the power connection, one with red insulation (BATT), and the other with black insulation (RTN).

Connect the power wires with red insulation to the BATT (-48V) wire receptacles on

TB1 and TB2. Connect the power wires with black insulation to the RTN wire receptacles on TB1 and TB2.

Note:

Two separate office battery supplies (–48V A and –48V B) are recommended. If separate office battery supplies are not available, connect a single office battery to both inputs (TB1 and TB2) to avoid a standing battery-failure alarm.

GPS Antenna

Use the supplied 90 degree adapter to connect the coaxial cable from the lightning suppressor or IF downconverter to the TNC connector labeled GPS ANT. Refer to

Figure 3-14

for the connector location.

10 MHz Output

Connect a user-supplied RG-58 coaxial cable from the connector labeled 10 MHz to

the equipment that will use the 10 MHz output signal. See Figure 3-14

for the connector location.

E1 or Analog Synchronization Outputs

Caution:

To avoid damage to the system, do not connect the E1 output line directly to a point outside the building. The E1 output circuits do not provide lightning protection.

Connect the E1 or analog synchronization outputs at the wire-wrap pins or BNC connectors labeled E1 OUT A and E1 OUT B. If using the wire-wrap pins, connect the tip wire to the pins labeled T, the ring wire to the pins labeled R, and the shield to

the pins labeled S. See Figure 3-14

for the location of the connectors and pins, and

Figure 3-16

for the wire-wrap connections.

Notes:

1.

For wire-wrap connections, the shield pin is provided to ground the cable shield at the shelf, if required. Normally, the shield is grounded at the source. Grounding the shield at both ends is not recommended.

2.

A BNC connector can be used for one output, and a wire-wrap connector can be used for the other output, but do not use the

BNC and wire-wrap connectors of the same output simultaneously. For example, a BNC connector can be used for output A and the wire-wrap pins for output B, but do not use the output A BNC connector with the output A wire-wrap connector.

Connecting E1 or Analog Reference Inputs

Caution:

To avoid damage to the system, do not connect the E1 output line directly to a point outside the building. The E1 output circuits do not provide lightning protection.

E1 or analog reference sources, traceable to an independent Stratum 1 source, can be connected to further increase holdover stability, or to be monitored by the

TimeSource 3600. In either case, connect reference inputs to the wire-wrap pins or

BNC connectors labeled SPAN IN A and SPAN IN B. If using the wire-wrap pins, connect the tip wire to the pin labeled T, the ring wire to the pin labeled R, and the

shield (if connected at the TimeSource 3600) to the pin labeled S. See Figure 3-14

for the location of the connectors and pins, and Figure 3-17

for the wire-wrap connections.

Notes:

1.

The shield pin is capacitively coupled to ground. Normally, the shield is grounded at the source. Grounding the shield at both ends is not recommended.

2.

A BNC connector can be used for one input, and a wire-wrap connector can be used for the other input, but do not use the

BNC and wire-wrap connectors of the same input simultaneously.

For example, a BNC connector can be used for input A and the wire-wrap pins for input B, but do not use the input A BNC connector with the input A wire-wrap connector.

Figure 3-20. Eight Mixed E1/T1 Outputs Connections

Module for ESCIU Ports (990-72060-04 System Only)

The ESCIU ports ( Figure 3-21 ) have a different function than the synchronization

outputs. A synchronization output provides an all-ones reference clock signals for network elements. An ESCIU port carries live E1 traffic, and synchronizes the live traffic as it passes through. 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 E1 signals that conform to CCITT G.703 paragraph 6 specifications. The network element can be configured to extract its timing from the live E1 traffic signal.

A bypass relay directs E1 traffic around the ESCIU circuitry to maintain span continuity if a TimeSource 3600 fault occurs.

Cutover Procedures for Out-of-Service Equipment

If DDF access jack sets

are not

cabled to the ESCIU module, the following out-of- service cutover procedure must be used. Consult the local company Installation Job

Specifications to ensure that the network element to be retimed is connected to the

ESCIU module correctly. Refer to Figure 3-22

for the following procedure:

1. Remove from service (turn down) the traffic trunks on the E1 system to be cutover to the ESCIU module.

2. Remove the existing cabling in both directions between the transmit (OUT) and receive (IN) terminals of the NEs that will connect to the ESCIU module.

3. In the direction not to be synchronized by the ESCIU module, connect new cables from the ESCIU module RTNx IN connector to the NE transmit (OUT) terminal, and connect from the ESCIU module RTNx OUT connector to the NE receive (IN) terminal.

4. In the direction to be synchronized by the ESCIU module, connect new cables from the ESCIU module IN connector to the NE transmit (OUT) terminal, and connect from the ESCIU module OUT connector to the NE receive (IN) terminal.

5. Verify that there are no alarms on the NEs on the E1 system. If there are alarms, recheck the new cabling between the NEs and the ESCIU module.

Note:

If the TimeSource 3600 is still in warm-up or searching for GPS satellites, alarms may be present. All synchronization-related alarms should clear while the TimeSource 3600 is in steady-state operation.

Procedure

Note:

If using the TimeScan Craft software program for the power-up procedure, see the

TL1 commands in this Procedure.

Use the Activate User command to log onto the system.

ACT-USER::TELECOM:<ctag>::TS3000!!;

Skip this step if the current unit is equipped with a roof antenna.

Use the Edit Equipment command to change the antenna locating mode to manual and to enter the latitude, longitude, and altitude. In manual mode, the survey process used to determine the antenna’s exact position starts with this information.

Note:

Enter data carefully. When entering degrees, an error of a single degree will cause the system location accuracy to be off by as much as 100 km.

ED-EQPT::GPS:<ctag>:::ANTMODE=MANUAL,MANLAT=a-b-c-d,

MANLONG=e-f-g-h,MANELEVALT=i; a – north (a = N) or south (a = S) of the equator b – degrees of latitude (b = 0 to 179) c – minutes of the degree (c = 0 to 59) d – decimal fraction of the minute (d = 000 to 999) e – east (e = E) or west (e = W) of the Greenwich Meridian f – degrees of longitude (f = 0 to 179) g – minutes of the degree (g = 0 to 59) h – decimal fraction of the minute (h = 000 to 999) i – elevation, or altitude, of the antenna in meters

Example command to set the latitude, longitude, and altitude of the antenna:

ED-EQPT::GPS:<ctag>:::ANTMODE=MANUAL,MANLAT=N-37-19-016,

MANLONG=W-121-59-246,MANELEVALT=12;

Notes:

1.

The TimeSource 3600 can find its position on the earth without latitude, longitude, and altitude entered, but the process may take several hours, and may not result in the position accuracy (within 200 m) required for the system to perform to specification. It is recommended that the information be obtained and manually entered by the user.

2.

Latitude, longitude, and altitude data can be obtained through the use of a GPS hand-held receiver (user supplied). Location mapping software is also available for personal computers, which can be used to obtain latitude and longitude. When the entered figures are within 200 m of the actual coordinates, the TimeSource 3600 typically delivers UTC traceable timing within 1 h of applying power. Warm-up times vary greatly depending on the window location and antenna placement.

3.

Obtain latitude, longitude, and altitude outdoors when using a GPS hand-held receiver, to ensure an accurate reading. Do not use the GPS hand-held receiver inside the building near the window or wall where the antenna will be installed. GPS hand-held receivers do not provide an accurate location reading when used indoors.

Procedure

If not using an Element Manager, skip to

Step 28 . If not using a separate port to send

autonomous messages to an Element Manager, skip to Step 27

. 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 3600 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 Manager.

ED-EQPT::TS3600:<ctag>:::IPEM1=a,IPEM1PORT=b[,IPEM2=a]

[,IPEM2PORT=b][,IPINACT=c];

IPEM1=a – Primary Element Manager’s IP address in the form a.a.a.a (each a is an independent value of 0 to 255)

IPEM1PORT=b – Primary Element Manager’s Ethernet port address (b = 0 to 65535)

IPEM2=a – Alternate Element Manager’s IP address in the form a.a.a.a (each a is an independent value of 0 to 255)

IPEM2PORT=b – Alternate Element Manager’s Ethernet port address (b = 0 to 65535)

IPINACT=c – Disconnects from the Element Manager if an autonomous message is not developed during this number of 100-ms units of inactivity (0 to 10,000, where 0 deactivates the timer)

Chapter 3 Installing the TimeSource 3600

Powering Up the TimeSource 3600

Procedure 3-6. Power-Up (Continued)

Step

27.

Procedure

Use the Edit Communications command to set the communications parameters of port

5551. 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:

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)

ECHO=INH – (does not echo characters received)

COMPRI=ALW1 – (normal communication, including autonomous messages)

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

SWCONTROL=INH – (uses no flow control)

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

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

[ENDOFTEXT=d[,]][ECHO=b[,]][COMPRI=e[,]][AUTOLOGOFF=c[,]]

[SWCONTROL=b];

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:

Powering Up the TimeSource 3600

Procedure 3-6. Power-Up (Continued)

Step

28.

29.

30.

31.

32.

Procedure

If the results of

Step 19 indicate the antenna cable delay and elevation mask are set as

desired, skip to Step 29

. Use the Edit Equipment command to set the length of cable between the antenna and the TimeSource 3600 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=a,ANTELEVMASK=b; a – antenna cable delay in meters (a = 0 to 330) b – antenna elevation mask angle in degrees (b = 0 to 45) (see note below)

Note:

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

3600 masks out satellite signals, measured as an angle of elevation from the horizon.

Reflections or other anomalies may disturb signals received from an area of the sky that has obstructions, usually the area near the ground. Masking that part of the sky 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 30

. Use the Edit Equipment command to set the

TOD output.

ED-EQPT::TS3600:<ctag>:::TOD=b; b – TOD format (b = Cisco or NTP4)

If not using ESCIU ports, skip to

Step 31 . Use the Edit Equipment command to specify

how the ESCIU performs during holdover:

ED-EQPT::TS3600:<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 allow or inhibit alarm conditioning on the outputs.

Inhibiting the alarm conditioning forces the TimeSource 3600 to continue to output valid timing signals while in major alarm. This may be useful when testing, troubleshooting, or in installations where a TimeSource 3600 that is in major alarm may produce better timing signals than other sources (for example, offices without additional holdover clocks in a distribution shelf).

ED-EQPT::TS3600:<ctag>:::ALMCOND=b; b – alarm conditioning of the outputs (b = ALW or INH)

Use the Copy Memory command to copy the database from volatile to nonvolatile memory within the TimeSource 3600.

CPY-MEM:[tid]:TS3600:<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.

Chapter 3 Installing the TimeSource 3600

Powering Up the TimeSource 3600

Procedure 3-6. Power-Up (Continued)

Step

33.

Procedure

When the GPS signals have been acquired and the outputs are stable enough to output a signal, the TimeSource enters a settling period. During the settling period, the following conditions exist:

Status GPS lamp is green

Status SYS lamp is green

Any Span lamp is green when its input is connected, entered, contains valid framing, and is usable for ensembling

All outputs are functioning according to specifications or in a slightly degraded mode

A TL1 autonomous “settling period” event message exists.

Notes:

1.

In roof antenna installations, the nominal time to reach normal operation (output a

PRS signal) is 20 min. If normal operation has not been reached after 40 min, refer to the Troubleshooting chapter.

2.

The settling period is the condition where this clock is beyond the warm-up state but not yet in steady state operation. Steady state operation is indicated by the clearing of the “settling period” event.

3.

In window or wall antenna installations, the nominal time to reach normal operation

(output a PRS signal) is variable, depending on the view of the sky and the satellite positions at the time of power-up, and may take up to several hours. If normal operation is not reached, refer to the Troubleshooting chapter.

4.

The TimeSource 3600 develops and sends timing within the PRS specification during normal operation and during any event (other than settling period) or minor alarm, but not during a major or critical alarm.

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 4-2

shows the completed response format. COMPLD indicates that the command was completed without error.

Note:

If the command was a query, additional information would be displayed before the semicolon.

Commands

Copy Memory

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

TimeSource 3600, or copies the system database to nonvolatile memory.

The Software Release Notice (included with this software release) contains detailed instructions for copying programs from an external computer to nonvolatile memory.

Note:

Clear any existing alarms before using this command.

The database is automatically copied to nonvolatile memory once per hour.

However, if power to the TimeSource 3600 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 3600, the command format is:

Commands

Edit Date

This command changes the system date and time. The command format is:

ED-DAT:[<tid>]::<ctag>::<date>,[<time>]

:[MODE=a];

Parameter Value Description

date in the format a-b-c a = <year> 4-digit year b = 01 to 12 Month c = 01 to 31 Day a = 00 to 23 Hour of the day time in the format a-b-c

(Note: 1) b = 00 to 59 Minutes c = 00 to 59 Seconds

MODE=a a = UTC

(Note: 2)

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

Note:

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.

2

For example, when the UTC time is 01:12:10, setting the local time to

18:50:30 will 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.

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

The date/time 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:

097-72060-01 Revision J – June, 2007

TimeSource 3600 User’s Guide 135

Chapter 4 TL1 Reference

Commands

– 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. Refer to the following examples:

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:

ED-DAT:::<ctag>::2000-08-13;

Example to change to local time:

ED-DAT:::<ctag>::2000-08-13,07-00-00:MODE=LOCAL;

Commands

Note:

1 This parameter affects all Ethernet ports. Close the Ethernet ports and log off all users before issuing a command with this parameter. The TimeSource does no filtering to verify an improper network address entry.

Users should verify correct network addresses with Network Administrators and take care to enter correct addresses.

2 Port 5550 makes a connection to this element manager to send TL1 autonomous messages, and closes the connection when the transmission is complete.

3 Port 5551 accepts a connection from this element manager for TL1 commands and responses.

4 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::TS3600: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,

TS3600 will generate a major alarm with an SA flag. These parameters can then be verified using the

RTRV-EQPT command.

5 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::TS3600: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,

TS3600 will generate a major alarm with an SA flag. These parameters can then be verified using the

RTRV-EQPT command.

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

7 When the TimeSource 3600 uses a roof antenna, only the parameters ANTCBLDLY and ANTELEVMASK, and the mode ANTMODE=AUTO, are allowed.

8 The TimeSource 3600 uses the MANLAT, MANLONG, and MANELEV values for latitude, longitude, and elevation when ANTMODE=MANUAL becomes active. The TimeSource 3600 uses these values as starting points for processing the antenna position. Changes to these values are ignored while the TimeSource 3600 is in the AUTO mode.

9 A span must have been put into service using the ENT-EQPT command before setting the ENSEMBLER and SSM parameters.

10 The span input must be a digital 2.048 Mb/s E1 signal to use SSM. If not, the command is denied.

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

12 When output framing is set to NONE (analog), ALMOUT=SQUELCH turns off the outputs during holdover alarm. ALMOUT=AIS or ALMOUT=SSM converts E1 output framing to digital format to provide alarm signaling during alarm. Set alarm condition to disabled to maintain analog output during alarm.

13 All commands on DCDUSERPORT having TID which equals SID of the DCD are forwarded to the DCD.

Similarly, the responses from the DCD are sent to the provisioned DCDUSERPORT.

Note:

1 All commands on DCDUSERPORT TID which equal SID of the DCD are forwarded to the DCD. Similarly, the responses from the DCD are sent to the provisioned DCDUSERPORT.

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::TS3600: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,

TS3600 will generate a major alarm with an SA flag. These parameters can then be verified using the

RTRV-EQPT command.

PHASE1S Data types:

One 15 minute bin from the last 24 hours of data as 900 seconds of data. To select a 15 minute bin, enter mondat and montm. Any mondat/montm combination outside of the past 24 hour window is denied. Any time increment may be entered. The system rounds the value to the nearest bin.

Entered minutes of 1 to 15 correspond to the first 15 minute bin, 16 to 30 correspond to the second 15 minute bin, etc.

The first monitor value is the first second of the 900 second window.

The 900 seconds of data is broken into 9 groups of 100 seconds. For each group of 100 seconds, the first value is the absolute 1 second phase for that group. The absolute 1 second phase value is followed by 99 seconds of delta phase values.

PHASE 1M Data types

The TimeSource 3600 collects a full 7 days of 1 minute phase data.

The 1 minute phase data is displayed in 1 hour groups. Each request for 1 minute phase is synchronized to the hour.

Any mondat/montm combination outside of the past 7 day window is denied. Any time increment may be entered. The system rounds the value to the nearest hour, i.e., the minute and second field of the montm is ignored.

The first value (monval) is the oldest value in the range selected. For example, if montm = 8:45:32, the first monval will exceed time 8:00:00 followed by the value at 8:01:00, etc.
