Page 13: Description
Chapter Chapter Description This chapter provides an overview of the global positioning system, and a physical and functional description of the TimeSource 3000.
Page 14: Overview
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 stand- alone office PRS. With the optional inputs ensembled, overall system performance is improved, and holdover is extended if GPS signals become disrupted.

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.
Page 16: Physical Description
Physical Description The TimeSource 3000 consists of a shelf, a plug-in card, an antenna, cables, hardware, and software. An optional factory- installed daughtercard may be included to provide eight additional T1 outputs, eight additional composite clock outputs, or two additional IRIG-B TOD timing outputs.
Page 17: Functional Description
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.

Page 19: Antenna
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.
Page 20: Clock Extractors
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. TimeSource 3000...
Page 21: Eight Additional T1 Outputs (Optional)
Eight Additional T1 Outputs (Optional) This option provides eight additional T1 outputs at the OPTIONS I/O wire-wrap pins. These outputs function the same as the standard T1 outputs. TOD Output The BesTime Ensemble Timing Generator provides the timing for the TOD timing signal available at the RJ-45 connector, which provides time code to devices compatible with NTP Type 4 or Cisco format.
Page 22: Composite Clock Outputs (Optional)
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.

Page 25: Lightning Suppressor Guidelines
Lightning Suppressor Guidelines • Mount the lightning suppressor within 15 feet of a valid, direct, low impedance, low resistance, earth ground connec- tion point. Valid earth grounds include the roof ring ground system, building structural steel, or a Central Office ground plate.
Page 26: Antenna Location Guidelines
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.)

Page 32: Cabling Considerations
• 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. TimeSource 3000...
Page 33: Standard Configuration
Two cables are required: one to connect the antenna to the lightning suppressor and another to connect the lightning suppressor to the TimeSource 3000 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.
Page 34: Optional Configuration
If 5 MHz signals from a DCD Shelf are used as remote oscillator inputs, a 5 MHz Isolator Kit must be used between the DCD Shelves listed below and the TimeSource 3000 Shelf. Refer to Field Service Bulletin FSB 098-40620-19R2 for details.
Page 35 The isolation module is used to reduce potential noise coupling, and match impedances in the cables between the DCD master shelf and TimeSource 3000. It also converts the 5 MHz output from a square wave to a sine wave. The isolation module is installed between the TimeSource 3000 Shelf and the DCD master shelf.

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.

Report Alarm This autonomous message appears when an alarm is raised, and appears again when the alarm is cleared. Message: <sid> <date> <time> <almcde> <atag> REPT ALM <modifier> "<aid>:<ntfcncde>,<condtype>,<srveff>, <ocrdat>,<ocrtm>,,,:\"<conddescr>\ "[:<dgntype>]" Note: Refer to Table J for parameter definitions.
