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.

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, allones, 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 standalone 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.

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, 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

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

TOD timing outputs.

The shelf (Figure 1) can be mounted in a 48 cm rack or an ETSI

53.5 cm rack. 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

Mechanical Window Antenna

The mechanical window antenna (Figure 3) may be attached to a

window sill or wall, in any position that allows the antenna to be moved flush against the window. The antenna can be swung away from the window for window maintenance, and returned to its original position.

A single length of coaxial cable carries signals and power between the antenna assembly and the shelf.

Functional Description

Overview

Figure 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 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.

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.

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.

2

BesTime Ensemble Timing Generator

Clock signals from the GPS antenna (via the IF interface), local oscillator, and two 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.

Action

Determine the shelf location.

Determine the best location for mounting the antenna (less than 330 m of cable

from the shelf). Use the guidelines and considerations in the Roof Antenna Location and Cabling Guidelines section.

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

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 the 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% 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 8.)

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 9).

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

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

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

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

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

TimeSource 3600

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 minimum horizontal distance from other receiving antennas is

1 meter.

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

no less than 3 meters (Figure 10).

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. All cables should be routed in accordance with local company practices.

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 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 (0.812 mm [20 AWG], 75 ohm coaxial) with male TNC connectors attached, in the following lengths:

• 3 m cable (060-72010-01)

• 6 m cable (060-72010-02)

• 15 m cable (060-72010-05)

• 30 m cable (060-72010-10)

• 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)

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.

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 11) 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 (0.812 mm [20 AWG], 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)

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

If 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 adapter (also provided) 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.

RJ-422–to–RS-232 TOD Conver ter

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 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 fourpair 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.

• 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 use sandpaper or a file to remove oxidation 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 25).

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

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 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 24 for the location of the terminals on the

rear of the shelf, and refer to Figure 25 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 connector panel to the office battery source connection.

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

E1 or Analog Synchronization Outputs

Warning:

Because the E1 output circuits do not provide lightning protection, do not connect the E1 output line directly to a point outside the building. Failure to observe this warning may result in equipment damage.

Connect the E1 or analog synchronization outputs at the wirewrap 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 24 for the location of the connectors and

pins, and Figure 26 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.

E1 or Analog Reference Inputs

Warning:

Because the E1 input circuits do not provide lightning protection, do not connect the E1 input line directly to a point outside the building. Failure to observe this warning may result in equipment damage.

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 wirewrap 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 24 for the

location of the connectors and pins, and Figure 27 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.

Module for ESCIU Por ts

(990-72060-04 System Only)

The ESCIU ports (Figure 30) 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 31 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.

6. Restore (turn up) the traffic trunks to service.

Cutover Procedures for In-Service Equipment

If standard digital signal level access jack sets, such as DDF or DSX-1 jacks, were cabled to the ESCIU module, the following in-service cutover procedure must be used. Consult the local company

Installation Job Specifications to ensure that the network element to be retimed from the ESCIU module is connected to the ESCIU module

A OUT terminals. Refer to Figure 32 for the following procedure:

1. Patch a bridging repeater from the MON jack of one NE to the IN jack of the other NE in both directions of transmission on the E1 system to be cutover. Place a 75

termination plug in the OUT jack in each direction.

2. Remove the cross-connect wiring from the OUT and IN jacks (offnormal side of jacks) in both directions of transmission.

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. Remove the 75

(E1) termination plug from the OUT jack and patch cords from the NE IN jack. The E1 system bitstream is now going through the ESCIU module.

6. Verify that there are no alarms on the NEs on the E1 system. If there are alarms, repeat Step 1 and recheck the cross-connect

wiring. Repeat Step 5.

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.

7. Remove the remaining patch cords from the NE MON jack.

Procedure

Install the battery source fuse(s) in the rack fuse bay that supplies power to the

TimeSource 3600. The TimeSource 3600 enters its warm-up mode after approximately 60 s when power is applied. During the warm-up period, the following conditions exist:

• Status GPS lamp is green

• Status SYS lamp is off

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

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

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

• ESCIU por ts (if equipped) are on (unreliable while Status SYS lamp is off)

Notes:

1. The CRIT lamp and other alarm indication lamps may light. The host computer may display transient and standing alarm condition messages. Ignore alarms while the Status SYS lamp is off during warm-up, unless alarms apply to inputs and outputs that were previously entered.

2. TL1 commands may be entered during warm-up. Inputs and outputs can be enabled, and system parameters can be set or changed.

Procedure

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

Note:

If using the TimeScan Craft software program for the power-up procedure, see the TimeScan Craft manual (contained on the TimeScan Craft CD) for the appropriate TimeScan commands to use in place of the Tl1 commands. Follow the steps of this procedure, substituting the TimeScan Craft commands. Use the

Activate User command to log onto the system.

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

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 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 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:

Notes:

1. The TimeSource 3600 can find its position on the ear th 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.

If UTC time is desired, skip to Step 18. 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)

Example command to set UTC time:

ED-DAT:::123::2000-06-15:MODE=UTC;

Use the Retrieve Equipment command to identify whether and how the inputs have been provisioned.

RTRV-EQPT::ALL:<ctag>;

Notes:

1. Observe those results with an <aid> of SPAN-a. If MONITOR=ALW appears for an input, that input has previously been entered. If ENSEMBLER=ALW appears for an input, that input has been set to be ensembled.

2. Note the results of the Retrieve Equipment command to set the remaining parameters in this procedure.

3. Factory default settings are found at the end of this Power Up procedure section.

If the results of Step 19 indicate the span inputs (if used) are set as desired, skip to

Step 24. Use the Enter Equipment command to monitor each available span input,

and to specify whether those inputs are to be ensembled.

ENT-EQPT::SPAN-a:<ctag>:::ENSEMBLER=b; a = span input (a = A or B) b = whether this input is ensembled (b = ALW ensembles the input; b = INH inhibits the input from being ensembled)

Procedure

If not using ESCIU ports, skip to Step 30. 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 specify how the ESCIU performs with a lossof-signal (LOS) alarm on the incoming span:

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

NE with the original input alarm (b = PASSTHRU).

If the results of Step 19 indicate the antenna cable delay and elevation mask are set

as desired, skip to Step 34. 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 32. Use the Edit Equipment command to

set the TOD output.

ED-EQPT::TS3600:<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 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.

Procedure G. Power Up (cont’d)

Step

34

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 or minor alarm, but not during a major or critical alarm.

Command Format

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.

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.

Definition

Value of the performance monitoring data.

Notification code showing the alarm severity, which is one of the following:

<ocrdat>

<ocrtm>

<pid>

<sid>

<spec_block>

<srveff>

Occurrence date in the 8-digit form: yyyy-mm-dd (command) or yyyy:mm:dd

(response or message), where yyyy is the year, mm is the month (01 to 12), and dd is the day of the month (01 to 31). For example, May 3, 2000 is 2000-05-03.

Occurrence time in the 6-digit form: hh-mm-ss (command) or hh:mm:ss

(response or message), where hh is hours (00 to 23), mm is minutes (00 to 59), and ss is seconds (00 to 59). For example, 2:34 pm is 14:34:00.

Private identifier, factory-set to “TS3000!!”. It is the initial password for the

TELECOM <uid>. Passwords are encrypted when stored in the

TimeSource 3600, and are never transmitted from the shelf. The pid contains a case-insensitive string of 8 to 10 ASCII characters, and must include at least one letter, one numeral, and one special character from the following:

! " $ % & ' ( ) * + - . / < > ? @

Source identifier of the equipment sending the message. The <sid> may contain a maximum of 20 characters (limited to letters, digits, and hyphens), and may begin with a letter. The <sid> is recommended to be the equipment’s CLLI code.

Replaced by a number of parameters within the command. Parameters are in the format <name>=<value>, may be entered in any order, and must be separated by a comma.

<vldty>

Definition

Target identifier of the equipment to which the command is directed. The tid must be a valid TL1 identifier of a maximum of 20 characters (limited to letters, digits, and hyphens) beginning with a letter. The <tid> is recommended to be the target's CLLI code, and can also be used as the <sid>. The <tid> can be null if the OS directly interfaces to the target. The <tid> can be omitted only if connection is made directly to a single TimeSource 3600 Shelf.

Current time in the six-digit form: hh-mm-ss (command) or hh:mm:ss (response or message), where hh is hours (00 to 23), mm is minutes (00 to 59), and ss is seconds (00 to 59). For example, 5:11:49 a.m. is 05:11:49.

User access level, used by a system administrator to assign a given level of access to system users. User access level ranges from 1 to 5, with 1 being the lowest access level, and 5 being the highest access level.

User identifier, factory-set to TELECOM. The <uid> contains alphanumeric, case-insensitive strings of 6 to 10 characters provisioned as valid login IDs.

User inactivity password which indicates the number of days a system user has not logged on to the system. The user inactivity timeout range is 0 to 180 days, with 0 indicating no timeout.

Universal Coordinated Time (UTC) in the 6-digit form: hh-mm-ss, where hh is hours (00 to 23), mm is minutes (00 to 59), and ss is seconds (00 to 59). For example, 2:34 pm is 14-34-00.

Copy Memory

This command copies a software program from an external computer to the TimeSource 3600, 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 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:

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. This parameter affects all Ethernet ports. Close the Ethernet ports and log off all users before issuing a command with this parameter.

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 the TimeSource 3600 uses a roof antenna, only the parameters ANTCBLDLY and ANTELEVMASK, and the mode

ANTMODE=AUTO, are allowed.

5. 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.

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

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

8. The span input must be a digital 2.048 Mb/s E1 signal to use

SSM. If not, the command is denied.

Note:

PHASE 1S 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.

• Entering the date or time is optional. Type a semicolon after montype to display the most recent statistics for the specified montype.

• 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.
