Page 20: Overview
32 redundant universal timing outputs; an optional Expansion Panel provides an additional 32 redundant outputs. Using Symmetricom’s SmartClock™ technology design, the oscillators within the IOCs are enhanced with improved performance and accuracy. Using intelligent firmware algorithms, SmartClock “learns” the effects of the ageing of the clock while it is locked to a reference signal and stores this information in its memory.
Page 21: Shelves
Shelves The TimeProvider is available in two shelf models. Each shelf supports up to 32 redundant output channels. The TimeProvider 1000 is a 175 mm tall ETSI shelf that meets the requirements of ETSI 300 119-4 January 1994. Figure 1-1 shows the TimeProvider 1000 shelf.
Page 22: Expansion Panel
Chapter 1 Overview of the TimeProvider Overview Figure 1-2. TimeProvider 1100 Rear Access Shelf Expansion Panel The TimeProvider has an optional Expansion Panel that doubles (to 64) the number of output channels available. Figure 1-3 shows the rear-access version of the Expansion Panel.
Page 23: Outputs
Chapter 1 Overview of the TimeProvider Overview The TimeProvider qualifies the input reference signals and detect the following errors: Loss of Signal (LOS), Alarm Indication Signal (AIS), Loss of Framing, and Synchronization Status Messages (SSM) where applicable. Reference Input Signals, on page 32, describes the inputs in more detail. Outputs The TimeProvider produces a variety of outputs to meet different signal standards.
Page 24: Operating Modes
PRS, INP1, or INP2 connectors are used in conjunction with BesTime to extend compliance with GR-2830/G.812 standards. The PRR mode uses Symmetricom’s BesTime servo control that allows the TimeProvider to continue providing outputs in case GPS tracking is lost, the GPS data loses integrity, or if the IMC is removed from the shelf.
Page 25: Performance Monitoring
Chapter 1 Overview of the TimeProvider Performance Monitoring Performance Monitoring The TimeProvider can monitor and qualify all enabled input signals based on phase measurements. It measures the phase differences between the inputs and the output of the corrected clock. From these phase measurements, the TimeProvider computes frequency offset and wander of the input signals.

Page 28: Functional Description
Chapter 1 Overview of the TimeProvider Functional Description Functional Description The TimeProvider consists of a main shelf and slots for two IOCs and one IMC. One plug-in Input module and up to four plug-in Output modules complete the main shelf, which provides up to 32 outputs. The optional Expansion Panel can provide up to 32 additional outputs, to provide a total of 64 outputs.
Page 29 Chapter 1 Overview of the TimeProvider Functional Description Input Module The Input module receives the incoming reference signals and contains the alarm input/output connector. A variety of connector modules allows you to select the connector style and input impedance to match the wiring system at the installation site.

Page 30: System Power
Chapter 1 Overview of the TimeProvider System Power Output Module The Output module provides the output connectors for the TimeProvider. You can install up to four Output modules on the main shelf. Like the Input module, each Output module uses one of a variety of connectors that match the wiring system at the installation site.
Page 31: Communication Ports
This EIA-232 port supports local control; you can configure the TimeProvider with TL1 commands using a terminal or personal computer (PC) with terminal emulation software or Symmetricom’s craft software, SynCraft. The connector is located on the front panel of the IMC. The default specifications are 9600-8-N-1. The Local port is configured as a DCE interface.
Page 32: Reference Input Signals
Chapter 1 Overview of the TimeProvider Reference Input Signals Reference Input Signals The Input module accepts one or two E1, 2.048 MHz analog, 1.544 MHz or 6.312 MHz analog (Japan-specific), T1, and Composite Clock (including JCC and JCC4) inputs on ports INP1 and INP2. The CC inputs are used solely for Subtending mode;...
Page 33: Ssms And Quality Level
Chapter 1 Overview of the TimeProvider Reference Input Signals Revertive Switching Telcordia GR-378 and GR-1244 define two reference selection modes: Revertive and Non-revertive. In the revertive mode, when an input used as the system reference is disqualified (for any reason), if that input returns, it reverts to the system reference when the disqualifying reason is removed.
Page 34: Ssu-Based Reference Selection Scenarios
Chapter 1 Overview of the TimeProvider Reference Input Signals If the incoming signal does not include SSMs, or if you disable them, then you can provision the Quality Level to an appropriate value. The QLEVEL value is used in the same manner as the incoming SSM to determine which input is used when the active input is disqualified.
Page 35: Gps Inputs
Non-revertive example. Priority Levels set to: INP1 = 3, and INP2 = 3 Revertive example. Priority Levels set to: INP1 = 1, and INP2 = 2 GPS Inputs Symmetricom provides a complete GPS antenna system for the TimeProvider. This includes the Symmetricom GPS Antenna, the TimeProvider Interface Unit (TPIU), and associated cables.
Page 36: Clock Performance
Chapter 1 Overview of the TimeProvider Clock Performance Clock Performance Two IOCs are available: A Rubidium-based version that meets ST2/Type II standards. This IOC meets or exceeds the ITU G.812 Type II specification. A Quartz-based version that meets ST3E/Type I standards. This IOC meets or exceeds the ST3E requirements in ANSI T1.101 and Telcordia GR-1244, as well as the ITU-T G.812 TYPE III specification and ITU-T G.812 Type I specification.

BesTime The TimeProvider uses Symmetricom’s BesTime algorithm when it is in the PRR mode to provide enhanced GR-2830-CORE performance during bridging or holdover situations. BesTime minimizes the effect of transients on the reference signal on the outputs of the TimeProvider by comparing them against the system reference to produce the most stable outputs from the TimeProvider.
