22 TimeProvider 500 2.0 User’s Guide 098-00172-000 Revision A – December, 2009
Chapter 1 Overview
Key Features
The TimeProvider 500 “translates” IEEE 1588v2 packet flow into E1/T1 signaling
outputs (G.823/G.824), eliminating the need to deploy embedded PTP software
clients in network endpoint devices such as wireless base stations (BTSs and Node
Bs), Digital Subscriber Line Access Multiplexer (DSLAM)s, and Line Terminating
Equipment (LTE).
The TimeProvider 500 PTP translation function enables legacy Time-Division
Multiplexing (TDM)-based devices to transparently send and receive critical timing
and synchronization signals over a packet-based, Ethernet backhaul network
without requiring any modifications to their existing hardware or software.
TimeProvider 500 is fully interoperable with Symmetricom’s TimeProvider 5000,
TimeHub, and SSU 2000 IEEE 1588v2 grandmaster products, as well as third-party
grandmaster products that comply with the IEEE 1588v2 protocol standard.
