  • Page 11: Chapter 1 Description

    Chapter 1 Description This chapter provides an overview of the global positioning system, and a physical and functional description.

  • Page 12: Overview

    The synchronization timing is traceable to the GPS, which provides the highest level of synchronization for telephony networks. The TimeSource 3100 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.

  • Page 13: 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 3100 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 14: Physical Description

    Physical Description The TimeSource 3100 consists of a shelf, a plug-in card, an antenna, cables, hardware, and software. Optional system configurations include eight additional E1 or analog outputs, two E1 synchronous clock insertion unit (ESCIU) ports, four IRIG-B TOD timing outputs, or eight mixed E1/T1 outputs.

    The antenna (Figure 2) 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. Figure 2. Antenna 31.4 cm 7.6 cm TimeSource 3100 Description 097-72020-01 Issue 9: November 2003...

  • Page 17: Functional Description

    Functional Description Overview Figure 3 shows the main functions of the TimeSource 3100. The center of the TimeSource 3100 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.

  • Page 19: Antenna

    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. TimeSource 3100 Description 097-72020-01 Issue 9: November 2003...

    Use of the Simple Network Time Protocol (SNTP) 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.

    This ensures that intermittent conditions are not flagged unnecessarily. During the normal working of the TimeSource 3100, 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.

    Signals closer to the horizon are often subject to multipath effects, which degrade the timing solution. The TimeSource 3100 can be set to ignore, or mask, all signals from the horizon to a chosen angle of elevation (mask angle). (See Figure 6.) Figure 6.
