The OSA 5331 is a compact
IEEE1588v2 Grandmaster driven by GPS and/or GLONASS. Additionally the OSA 5331
can be driven also by electrical input signals for frequency (2.048 MHz, E1),
phase (1PPS) and time-of-day (NMEA).
The main outputs are its ports
for PTP delivery, which can serve several hundreds of PTP Slaves. There are
also additional electrical outputs for frequency, phase and time-of-day. As
with all other Oscilloquartz products, the OSA 5331 can be managed locally and
remotely via TCP-IP.
The OSA 5320 is an IEEE1588 Slave
with 5 outputs providing a mix of frequency, phase and time-of-day outputs
driven by PTP packets received from a Grandmaster through the network. The OSA
5320’s PTP engine features sophisticated algorithms that will provide optimum
performance in the presence of packet delay variations inherent to IP networks.
When network conditions degrade beyond a certain level of performance, the OSA
5320 enters a holdover mode and maintains good synchronization performance at
the outputs until normal network conditions have returned.
In a typical case, the OSA 5548C
is equipped with one or two GPS-receiver cards which deliver frequency, phase
and time-of-day to the internal bus that also drive the IEEE1588v2 cards. The
OSA 5548C can accommodate up to 6 (in its compact version) and 20 IEEE1588
plug-in cards (in the larger version). The OSA 5548C output slots can be used
to provide diverse output signal types such as 2.048 MHz, E1, and NTP. The
modular structure allows customers to combine different output card types to
best fit their needs.
