Overview

The TimeSource 3000 is a Primary Reference Source (PRS) that receives and processes signals from GPS satellites, and outputs

Stratum 1 synchronization signals traceable to UTC. TimeSource

3000 applications include synchronization for central offices, radio base stations, transmission nodes, and other instances where a primary reference source can improve the performance of telephony network facilities.

The TimeSource 3000 creates timing outputs by ensembling signals from several sources. The sources include GPS signals, an onboard local oscillator, and optional T1 and remote oscillator signals. Timing outputs created from the ensemble are composed of the most stable and least noisy parts of each input.

Synchronization outputs are delivered in a framed, all-ones, T1 format, a 10 MHz signal, a 1 pps signal, composite clock signals

(optional), and time of day (TOD) signals.

The TimeSource 3000 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 3000 with its GPS input is a standalone office PRS. With the optional inputs ensembled, overall system performance is improved, and holdover is extended if GPS signals become 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 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 3000 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.

Physical Description

The TimeSource 3000 consists of a shelf, a plug-in card, an antenna, cables, hardware, and software. An optional factoryinstalled daughtercard may be included to provide eight additional

T1 outputs, eight additional composite clock outputs, or two additional IRIG-B TOD timing outputs.

The shelf occupies two rack mounting units (RU), and can be mounted in a 19 inch rack or a 23 inch rack. Other than a communications connector on the front panel, all connectors are at the rear of the shelf.

The antenna (Figure 1) is encased in weather -resistant plastic

housing for outdoor installation, usually on a roof. A single coaxial cable carries signals and power between the antenna and the shelf.

Functional Description

Overview

Figure 2 shows the main functions of the TimeSource 3000. The

center of the TimeSource 3000 is the Ensemble Timing Generator, which uses the BesTime algorithm to analyze the phase and frequency relationships, individually and collectively, of the timing sources. Each type of timing source has a particular characteristic

that gives it an advantage over other sources, as listed in Table A.

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 housing includes a volute antenna, GPS receiver, amplifier, and intermediate-frequency (IF) downconverter.

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

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

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

IF Interface

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

Local Oscillator

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

BesTime Ensemble Timing Generator.

Clock Extractors

T1 signals (optional) enter on the SPAN IN A and B wire-wrap pins, and remote oscillator signals (optional) enter on the A and B REM

OSC connectors. From each external signal, a clock extractor circuit extracts a timing signal, which is sent to the BesTime

Ensemble Timing Generator.

Power Supply

A power converter filters and converts

48 volts dc power supplied to the shelf into the voltages required by the shelf.

BesTime Ensemble Timing Generator

Clock signals from the IF Interface, the local oscillator, the two T1 span lines, and the two remote oscillators are used as sources by the BesTime algorithms in the BesTime Ensemble Timing

Generator. The signals are analyzed for MTIE, TDEV, and other phase and frequency characteristics.

The BesTime Ensemble Timing Generator uses mathematical models to analyze each clock. The ensemble algorithms use the comparisons and analyses to generate a highly stable timing signal, which uses the best qualities of all inputs.

T1 Outputs

The BesTime Ensemble Timing Generator provides the timing for the T1 timing signal available at the T1 OUT A and B connectors in a framed, all-ones format, which can be set to ESF or D4 framing.

Alarm Interface

The microprocessor delivers alarms to normally open dry-contact type connections. Alarms are also indicated by the front-panel status lamps, and TL1 messages reported via the communication ports.

Ethernet

TimeSource 3000 has one physical Ethernet port with six virtual ports to carry TL1 commands, responses, and autonomous messages between the TimeSource 3000 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.

Two aditional ports communicate with Element Managers, which may have NMS, OSMF, or similar software. An Element Manager establishes a connection with one port (5551) for TL1 commands and responses. Another port (5550) establishes a connection to an

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

Action

Determine the location of the grounding point for the lightning suppressor. The lightning suppressor must be located within 15 ft of this point. If the grounding point is inside the building, the grounding point must be within 50 cable feet of where the antenna cable enters the building. Valid lightning suppressor grounding points are as follows:

• Valid roof ring ground system

• Cad weld to building structure steel

• Central Office ground plate

Determine the best location for mounting the antenna. The ideal location is where the antenna has an unobstructed view of the sky, from the horizon to zenith, for 360° around the horizon.

Determine the shelf location.

Determine the cable length between the antenna, and the lightning suppressor

location determined in Steps 1 and 2.

Determine the cable length between the lightning suppressor and the shelf location

determined in Steps 1 and 3.

Determine the –48 V power source for the shelf.

Determine if 5 MHz signals from a Symmetricom Digital Clock Distributor (DCD)

Shelf will be used as remote oscillator inputs (optional).

Lightning Suppressor Guidelines

• Mount the lightning suppressor within 15 feet of a valid, direct, low impedance, low resistance, earth ground connection point. Valid earth grounds include the roof ring ground system, building structural steel, or a Central Office ground plate. If the grounding point is inside the building, mount the suppressor within 50 feet of the cable entry into the building.

Warning:

Metal clamps that form a complete metal circle around the antenna cable or the cable conduit are not allowed. The ring clamp acts like a choke coil to induced currents, which resists current flow and hampers proper lightning protection.

Warning:

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

.

Note:

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

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

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

Warning:

Avoid small-radius turns and unnecessary turns.

Antenna Location Guidelines

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

A compromise often must be made between location and satellite field of view. The smaller the field of view, the fewer the number of satellites that can be used in the timing solution for GPS derived time. With fewer satellites, the TimeSource 3000 may experience

GPS events (temporary loss of contact with four or more GPS signals).

Signals closer to the horizon are often subject to multipath effects, which degrade the timing solution. The TimeSource 3000 can be set to ignore, or mask, all signals from the horizon to a chosen

angle of elevation (mask angle). (See Figure 3.)

Note:

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.

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

• Total of obstructions above the mask angle must not obscure more than 25 percent of the total field of view (90 degrees of

azimuth) (Figure 4).

• No single obstruction may block more than 12.5 percent of the view (45 degrees of azimuth).

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.

• The minimum vertical distance above parapets, obstructions, or horizontal metallic reflective surfaces is 4 feet.

• Do not locate the antenna within 30 degrees azimuth of the transmission direction of any transmitting antenna (to avoid overpowering the GPS reception, even though the transmitting antenna may operate at a different frequency).

• 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).

• Mount the antenna in a location with easy and safe access for future maintenance purposes.

• Mount the antenna on a mast of 1 inch diameter galvanized metal pipe (recommended). Do not use metal as a cable conduit.

Cabling Considerations

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.

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.

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 1,000 cable feet of the TimeSource 3000 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 four pair RS-422 cable, 1,000 feet maximum, with RJ-45 connectors on each end. Route this cable between the TimeSource 3000 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.

• Crimp an appropriate-size spade lug to the 16 AWG wire, bend the lug around the 6 AWG rod, and solder.

• Strip enough insulation from the 16 AWG wire to permit three complete turns around the 6 AWG rod and solder.

Note:

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

6 AWG rod is heated sufficiently to prevent a cold solder connection.

Without ground rod:

Crimp the supplied spade lug to the 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 16 AWG wire,

and connect it to the FRM terminals on TB1 and TB2 (Figure 11).

If the results of Step 18 indicate the remote oscillator inputs are set as desired, skip to

Step 21. Use the Enter Equipment command to monitor and/or ensemble each

remote oscillator input.

ENT-EQPT::RO-x:<ctag>:::ENSEMBLER=y; x y

= remote oscillator input (x = A or B)

= allow the input to be ensembled or inhibit the input from being ensembled (y = ALW causes the input to be monitored and ensembled; y = INH causes the input to be monitored, but not ensembled)

20 Use the Edit Equipment command to set the frequency of the remote oscillator inputs.

ED-EQPT::TS3000:<ctag>:::ROFREQ=x; x = remote oscillator frequency in MHz (x = 5 or 10)

21

If the results of Step 18 indicate the T1 span inputs are set as desired, skip to Step 25.

Use the Enter Equipment command to monitor each available T1 span input, and to specify whether those inputs are to be ensembled.

ENT-EQPT::SPAN-x:<ctag>:::ENSEMBLER=y; x y

= T1 span input (x = A or B)

= allow the input to be ensembled or inhibit the input from being ensembled (y = ALW or INH)

22 Use the Edit Equipment command to set the output signal framing format for each

T1 output, and set the mode for each T1 output during an alarm.

ED-EQPT::T1-x:<ctag>:::FRAMING=y,ALMOUT=z; x y z

= T1 output (x = A or B)

= framing format (y = ESF or D4)

Step Procedure

23 If not using a 990-72010-02 system, skip this step. Use the Edit Equipment command to set the output signal framing format for each additional T1 output, and set the mode for each T1 output during an alarm.

ED-EQPT::OPT-a:<ctag>:::FRAMING=b,ALMOUT=c; a = T1 output module port (a = 1 to 8) b = framing format (b = ESF or D4) c = T1 output during alarm (c = AIS, SQUELCH, or SSM) (for SSM, framing format must be ESF)

24 If not using performance monitoring, skip to Step 28. Use the Initialize Register command to reset the performance monitoring data to zero for all input spans.

INIT-REG-EQPT::ALL:<ctag>::ALL;

25

If the results of Step 18 indicate the antenna cable delay and elevation mask set are as

desired, skip to Step 26. Use the Edit Equipment command to set the length of cable

between the antenna and the TimeSource 3000 Shelf. This number should have been recorded during installation. Use the same command to set the antenna elevation mask angle.

ED-EQPT::GPS:<ctag>:::ANTCBLDLY=x,ANTELEVMASK=y; x y

=

= antenna cable delay in meters (x = 0 to 330) antenna elevation mask angle in degrees (y = 0 to 45) (see note below)

Note:

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

TimeSource 3000 masks out satellite signals, measured from the horizon to the desired angle of elevation. For example, if the sky is obstructed below 20° elevation, signals received from below that elevation may have reflections or other anomalies.

Masking those signals may allow the receiver to acquire GPS signals more quickly and accurately. Factory setting is 0.

If not using the TOD output, skip to Step 27. Use the Edit Equipment command to

set the TOD output.

ED-EQPT::TS3000:<ctag>:::TOD=y; y = TOD format (y = Cisco or NTP4)

27 Use the Edit Equipment command to allow or inhibit alarm conditioning on the outputs. Inhibiting the alarm conditioning forces the TimeSource 3000 to continue to output valid timing signals while in alarm. This may be useful when testing, troubleshooting, or in installations where the outputs generated by the TimeSource

3000 may be better than the alternative (for example, offices without additional holdover clocks in a distribution shelf).

ED-EQPT::TS3000:<ctag>:::ALMCOND=y; y = alarm conditioning of the outputs (y = ALW or INH)

If not using Ethernet, go to Step 32. Use the Edit Equipment command while

connected to COM1, COM2, or the CRAFT port to set the IP address, subnetwork mask, and gateway address for the current TimeSource 3000 unit, as required for proper operation in the managed element network. (These parameters affect all

Ethernet ports. The Ethernet port should be closed and all users logged off before issuing this command.)

ED-EQPT::TS3000:<ctag>:::IPNE=a,IPSUBNET=a,IPGATE=a;

IPNE=a = This unit’s IP address in the form a.a.a.a (each a is an independent value of 0 to 255)

Step Procedure

32 Use the Copy Memory command to copy the database from volatile to nonvolatile memory within the TimeSource 3000.

CPY-MEM:[tid]:TS3000:<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.

33 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 or Remote Oscillator 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. The nominal time to reach the beginning of the settling period is 20 min. If this state 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. The TimeSource 3000 develops and sends timing within the PRS specification during steady state operation and during any event (other than settling period) or minor alarm, but not during a major or critical alarm.

Conventions

Uppercase letters in a command designate parameter values which must be entered as shown. Lowercase letters in a command are the parameter name, and the specific values that must be

entered for the parameter. The Parameters section of this chapter

describes the parameters and the values where a value is the same for all parameters. Parameter values for a particular command are listed with the command. The system accepts either uppercase, lowercase, or a mixture of both, but upper and lower case cannot be mixed within a parameter block.

The following symbols are used in the input and response messages: encloses an optional parameter [ ]

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

| separates alternatives in a group of parameters, at least one of which must be entered

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 20 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.

Copy Memory

This command copies a software program from an external computer to the TimeSource 3000, or copies the system database to nonvolatile memory.

Notes:

1. Clear any existing alarms before using this command.

2. The database is automatically copied to nonvolatile memory once per hour. However, if power to the TimeSource 3000 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 3000, the command format is:

Edit Communication (cont’d)

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.

3. Baud rate, parity, and stop bits can only be configured on serial communication ports (1, 2, and 3).

4. Flow control is not implemented on communication port 3

(Craft port).

5. XON/XOFF flow control is simulated for Ethernet ports.

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.

2

• 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.
