Page 17 Chapter Chapter Description This chapter provides an overview of the global positioning system, and a physical and functional description.
Page 18: Overview
The synchronization timing is traceable to the GPS, which provides the highest level of synchronization for telephony networks. The TimeSource 3600 with its GPS input is a stand- alone office PRS. With the optional inputs ensembled, holdover is extended if GPS signals are disrupted.
Page 19: Global Positioning System
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.
Page 20: Physical Description
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 cable from the antenna is routed through a hole drilled in the wall. Coaxial cables carry signals and power between the antenna and the IF converter, and between the IF converter and the shelf.
Page 26: Functional Description
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.

TimeSource 3600 and an external terminal. Ethernet The TimeSource 3600 has six Ethernet ports to carry TL1 commands, responses, and autonomous messages between the TimeSource 3600 and an external terminal, or an Element Manager, or both. The user can configure the IP address, subnet mask, and gateway address for the Ethernet ports.
Page 33 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 additional 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.

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.

Page 40: Antenna Location Examples
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...
Page 41 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.

Page 111 If not using Ethernet, go to Step 28. 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 3600 unit, as required for proper operation in the managed element network. (These parameters affect all Ethernet ports.
Page 112 Procedure G. Power Up (cont’d) Step Procedure Ports 5001, 5002, 5003 and 5004 on the TimeSource 3600 are used as though they were serial TL1 communication ports. The following values are set at the factory and appear at reset: MONMSG=INH (monitors only the current port for messages)
Page 113 Element Manager, skip to Step 27. Use the Edit Equipment command to set the IP address and port address of the Element Manager. Port 5550 connects to this address when the TimeSource 3600 develops a TL1 autonomous message, sends any messages, and closes the connection. An alternate Element Manager may be set up in case port 5550 cannot make a connection to the primary Element Manager.

Page 115 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.
Page 116 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).
Page 117 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.
