PTP8 - Enhanced PTP Network Slave Client

The PTP8 Network Time Client provides network operators with a highly accurate packet-based timing and synchronisation solution. The PTP8 converts the PTP protocol supplied across a packet network in to industry standard E1/T1, 1PPS, 10MHz, IRIG B and Serial Time Of Day (TOD) signals.

The PTP8 Enhanced Slave Network Time Client provides network operators and equipment manufacturers with a highly accurate packet-based timing and synchronisation solution.

The PTP8 receives, decode and converts the PTP IEEE1588v2 protocol supplied across a packet network in to industry standard E1/T1, 1PPS, 10MHz, IRIG B and Serial Time Of Day (TOD) signals and messages.

Commonly deployed as a local network time client alongside the Stratum 1 PTP80 Grandmaster, the unit provides a rapid and seamless upgrade of existing network infrastructure to packet based timing and synchronisation enabling operators to lower upgrade costs when migrating from a TDM to Ethernet backhaul architecture.

The unit provides two standard RJ45 connections to a 100BASE-T network one for configuration, firmware uploads and providing NTP (Network Time Protocol) and the other for PTP connection to the master or Grandmaster PTP clock. The units are available as desk mount or provided in a 1U 19” rack mount chassis with single or dual power supply options.

A 9 way D type socket is available for RS232 connection for configuration, status and firmware upload purposes (115.2kbaud, no parity, 8 bit characters and 1 stop bit). 1PPS and 10MHz outputs are provided via two BNC 50 Ohm sockets. E1 or T1 output via 75 Ohm BNC socket and 120 Ohm at RJ45 connector.

Typical Applications

The PTP8  is commonly specified where precision, reliability and security are key considerations in the network application.  These high integrity units are common place and thoroughly proven worldwide in PTP network timing applications where traceable, precision time stamping and time distribution is required.
