The Precision Time Protocol (PTP) is a solution for the distribution of synchronization over IP-based packet networks such as
IP, IP/MPLS, Ethernet, IP/xPON and IP/xDSL networks. PTP is also known by the name of the corresponding standard IEEE
1588-2008.
Oscilloquartz offers a comprehensive range of PTP products
covering all synchronization needs in the telecommunication
domain. The OSA 5320 PTP Slave is designed
to interoperate with PTP grandmaster clocks from
Oscilloquartz or from other vendors.
The OSA 5320 consists of a PTP protocol engine which
connects to one or several distant PTP Grandmaster
clocks over an IP or Ethernet network.
The PTP Slave
delivers frequency, phase and time-of-day over a set of
output ports featuring a variety of output formats. The
output port section is divided into a set of standard output
ports and a pluggable Output Extension Module.
The OSA 5320 is fully manageable. So-called PTP Profiles
are used to configure those parameters which are
crucial for the interoperability with the connected grandmaster
clock.
Typical applications are the synchronization of 2G, 3G,
cdma2000 and WiMax basestations, of xPON optical line
terminals, etc.
PTP allows the distribution of accurate frequency, phase
and time-of-day to these applications even in cases
where the transport network is asynchronous.
The typical PTP architecture consists of a PTP grandmaster
clock which delivers synchronization to a number of
PTP slave clocks.
