Functional Description
Overview
The TimeProvider 500 version 2.0 shown in Figure 1-1 is a stand-alone, one Rack
Unit (RU) device that provides a client-clock function with the ability to synchronize
to a grandmaster clock. To perform the client-clock function, the TimeProvider 500
uses IEEE-1588 v2 [often referred to as Precision Time Protocol (PTP)] as a
reference to steer 1PPS, 10MHz, and T1 and E1 outputs. TimeProvider 500 can be
configured and monitored using the Command-Line Interface (CLI) accessible
locally with the RS232 connection or remotely via a Telnet connection. The
TimeProvider 500 enables rapid migration from TDM-based to packet-based timing
and synchronization solutions.
