This chapter provides an overview of the global positioning system, and a physical and functional description.

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

Overview

S S

The TimeSource 3500 is a Primary Reference Source (PRS) that receives and processes signals from GPS satellites, and outputs

Stratum 1 synchronization signals traceable to UTC. TimeSource

3500 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.

S

The TimeSource 3500 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 3500 creates timing outputs by ensembling signals from several sources. The sources include GPS signals, an onboard rubidium local oscillator, and optional T1 signals. Timing outputs created from the ensemble are composed of the most stable and least noisy parts of each input. The performance of the

T1 sources can be monitored and classified using standard measures. Synchronization outputs are delivered in a framed, allones, T1 format, a 10 MHz signal, a 1 pps signal, a composite clock format (optional), and a choice of time of day (TOD) formats.

The TimeSource 3500 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 3500 with its GPS input is a standalone office PRS. With the optional inputs ensembled, holdover is extended if GPS signals are disrupted.

Global Positioning System

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.

S S

The satellites, circling the earth at approximately 12,550 statute miles, 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 3500 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.

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 3500 bridges frequent GPS outage periods with

BesTime algorithms, its 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

S S

The TimeSource 3500 consists of a shelf, a plug-in card, an antenna, cables, hardware, and software. Optional system configurations include eight additional T1 outputs, eight additional composite clock outputs, two IRIG-B TOD timing outputs, or eight mixed E1/T1 outputs.

S S S

The shelf (Figure 1) occupies two rack mounting units (RU), and can be mounted in a 19 inch rack or a 23 inch rack. One RU

(1.75 in.) of air space above the TimeSource 3500 is required for proper ventilation. Other than a communications connector on the front panel, all connectors are at the rear of the shelf.

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

Overview

Figure 6 shows the main functions of the TimeSource 3500. The center of the TimeSource 3500 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 A.

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

The antenna types include a roof antenna, mechanical window antenna, self-adhesive window antenna, or wall antenna. All antennas include a 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 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 3500 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.

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.

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.

Passthrough

The Passthrough feature of the TimeSource 3500 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 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 3500

• The TID (SID for DCD) is used to identify commands that go to the DCD product. The TimeSource 3500 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.

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 TS3500 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"

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.

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

) 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.

40

Bridging/Holdover Behavior

In the TimeSource 3500, 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 3500, 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 3500 has been designed to work around this situation.

The TimeSource 3500 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 GR-2830 PRC 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.

Description

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 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.

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.

S

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 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

42

Description

097-72050-01 Issue 7: August 2003

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 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)

Procedure A. Site Survey

Step Action

1 Determine the shelf location.

2 Determine the best location for mounting the antenna (less than 1,000 ft of cable from the shelf). Use the guidelines and considerations in the Roof Antenna

Location and Cabling Guidelines section.

3 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 15 ft. If the grounding point is inside the building, the cable length between the grounding point and the cable entry must be less than

50 ft. 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)

4 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.

5 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.

6 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 3500 power inputs.

Roof Antenna Location and Cabling Guidelines

DANGER:

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 3500 can use fewer satellites in the solution for GPS derived time. The TimeSource

3500 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 3500 can be set to ignore, or mask, all signals from the horizon up to a chosen angle of elevation (mask angle). (See Figure 9.)

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 10).

Location A Location B

Notes:

1. Place the antenna high enough on the tower that obstructions are below the mask angle; mount the antenna more than 3 feet 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 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 1/4 mile (400 yards) 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

The minimum horizontal distance from other receiving antennas is

3 feet.

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 10 feet (Figure 11).

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).

Warning:

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 15 feet 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:

• 10 feet (060-72010-01)

• 20 feet (060-72010-02)

• 50 feet (060-72010-05)

• 100 feet (060-72010-10)

• 200 feet (060-72010-20)

• 500 feet (060-72010-50)

• 600 feet (060-72010-60)

• 800 feet (060-72010-80)

• 1000 feet (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 3500 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.

Window and Wall Antenna Location Guidelines

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 possesses 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 12) and make a note of it. The mask angle, in degrees, will be entered during the initial setup.

RJ-422–to–RS-232 TOD Converter

If 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 RJ-422–to–RJ-232 TOD Converter Kit is required (ordered separately, part number 093-72000-98).

The RJ-422–to–RJ-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 1,000 cable feet of the TimeSource 3500 shelf, and within 50 cable feet of the device receiving the time code.

The user must supply two cables. One cable is a Category 5 fourpair RS-422 cable, 1,000 feet maximum, with RJ-45 connectors on each end. Route this cable between the TimeSource 3500 Shelf and the converter.

The other cable is an RS-232 data communications cable, 50 feet 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

S

The TimeSource 3500 Shelf can be mounted in a 19 inch rack or a

23 inch rack. The shelf is shipped with supplied mounting ears positioned for flush mounting on a 23 inch rack. Attach the mounting ears, as shown in Figure 13, for flush mounting or 5 inch offset mounting. Attach the long side of the mounting ear to the shelf for a 23 inch rack, and attach the short side of the mounting ears to the shelf for a 19 inch rack. Mount the shelf in the rack according to standard company practices. Leave one RU

(1.75 inches) of air space above the TimeSource 3500 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 if the holes in the rack are spaced 1.75 inches apart.

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 6 AWG (4.115 mm) 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

16 AWG (1.47 mm) wire, bend the lug around the 6 AWG

(4.115 mm) rod, and solder.

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

Note:

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

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

If the power is not to be connected immediately, replace the protective covers on the terminal blocks.

Without ground rod

Crimp the supplied spade lug to the 16 AWG (1.47 mm) 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 16 AWG (1.47 mm) wire, and connect it to the terminals on TB1 and TB2

(Figure 28).

If the power is not to be connected immediately, replace the protective covers on the terminal blocks.

Power

Warning:

This equipment is intended for installation in a restricted access location. Power source protective fusing must be provided as part of the installation.

Caution:

Do not apply power to the TimeSource 3500 before instructed in this procedure. Before connecting the power cables to the TimeSource 3500, 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 3500.

Power connections are made on power terminal blocks TB1 and

TB2. Refer to Figure 26 for the location of the terminals on the rear of the shelf, and refer to Figure 28 for the terminal connections.

Remove the protective covers from the terminal blocks, if covered.

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

Use two 18 AWG (1.024 mm) stranded wires for the power connection, one with red insulation (–48V), and the other with black insulation (RTN). Crimp a supplied spade lug to each wire.

Connect the power wires with red insulation to the –48V wire receptacles on TB1 and TB2. Connect the power wires with black insulation to the RTN wire receptacles on TB1 and TB2.

Replace the protective covers on the terminal blocks.

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.

Procedure

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.

Caution: 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 60 mi.

ED-EQPT::GPS:<ctag>:::ANTMODE=MANUAL,MANLAT=a-b-c-d, MANLONG=e-f-gh,MANELEVALT=i; a= north (a = N) or south (a = S) of the equator b= degrees of latitude (b = 0 to 60) c= minutes of the degree (c = 0 to 60) 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 180) g= minutes of the degree (g = 0 to 60) 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 3500 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 1/8 mi) 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 1/8 mi of the actual coordinates, the TimeSource 3500 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 handheld receiver, to ensure an accurate reading. Do not use the GPS handheld 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.

17 If UTC time is desired, skip to Step18. Use the Edit Date command to set the local date and time.

ED-DAT:::<ctag>::yyyy-mm-dd,hh-mm-ss:MODE=LOCAL; yyyy= year (yyyy = 1998 to 2096) mm= month (mm = 01 to 12) dd= day (dd = 01 to 31) hh= hours (hh = 00 to 23) mm= minutes (mm = 00 to 59) ss= seconds (ss = 00 to 59)

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 3500 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 3500 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::TS3500:<ctag>:::TOD=b; b= TOD format (b = Cisco or NTP4)

Use the Edit Equipment command to allow or inhibit alarm conditioning on the outputs. Inhibiting the alarm conditioning forces the TimeSource 3500 to continue to output valid timing signals while in major alarm. This may be useful when testing, troubleshooting, or in installations where a TimeSource 3500 that is in major alarm may produce better timing signals than other sources (for example, offices without additional holdover clocks in a distribution shelf).

31 Use the Copy Memory command to copy the database from volatile to nonvolatile memory within the TimeSource 3500.

CPY-MEM:[tid]:TS3500:<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.

32 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 3500 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.

For systems equipped with a Rubidium internal oscillator, the system output will be within the PRS mask if the unit has been in service and alarm free for more than 24 hours. Systems with Rubidium oscillators are the

090-72050-xx and the 090-72060-xx.

Conventions

S S

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.

S

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

Command Format

S

A command consists of a command code of up to three fields separated by hyphens, followed by parameter blocks separated by colons. Figure 36 shows the command format. Parameter blocks consist of one or more parameters separated by commas.

S

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.

Multiple parameters in a parameter block are separated by commas. Two commas occur next 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.

Copy Memory

This command copies a software program from an external computer to the TimeSource 3500, or copies the system database to nonvolatile memory.

Notes:

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

2. Clear any existing alarms before using this command.

3. The database is automatically copied to nonvolatile memory once per hour. However, if power to the TimeSource 3500 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 3500, the command format is:

Notes:

1. 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.

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.

Edit Date (cont’d)

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.

2. 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:

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.

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

7. 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::TS3500: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, TS3500 will generate a major alarm with an SA flag. These parameters can then be verified using the RTRV-EQPT command.

8. All commands on DCDUSERPORT having TID which equals

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::TS3000: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, TS3000 will generate a major alarm with an SA flag. These parameters can then be verified using the RTRV-EQPT command.

• The TimeSource 3500 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.
