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 5330 PTP
Grandmaster is designed to interoperate with PTP Slaves
from Oscilloquartz or from other vendors.
The OSA 5330 consists of a GPS-receiver and a PTP
protocol engine delivering PTP service over an Ethernet
port.
The PTP Grandmaster transfers frequency, phase and
time-of-day to remote PTP Slaves over an IP or Ethernet
network.
The OSA 5330 also features auxiliary input ports for operation
without the GPS-receiver. Thus the OSA 5330 can
also be driven by a co-located SSU providing the required
output signals.
The OSA 5330 is fully manageable. So-called PTP Profiles
are used to configure those parameters which are crucial
for the interoperability with the connected slaves.
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.
