Packet-over-Sonet
POS to HSSI Converter
_________________________________________________________________
The Metrodata PA1000 converts data from byte-oriented HDLC, as used on Packet-overSonet (POS) interfaces, to bit-oriented HDLC as found on HSSI interfaces.
The PA1000 serves two purposes:
n
it enables connection between a POS based router and a HSSI based router
n
it enables a POS based router to be connected to a satellite modem and
to operate at data rates below 155 Mbps
The PA1000 provides a solution for satellite operators wishing to use high performance
POS based routers without the need to use valuable chassis slots for low speed HSSI
serial interfaces. In addition, the PA1000 supports non-standard data rates and asymmetric
operation, thus providing a flexible solution for the user.
The PA1000 rate-adapts by stripping flags out of the data stream and transporting only the
actual packet data. It is transparent to packet payload and may operate with any protocol
that both the POS and HSSI devices support, such as PPP and Frame Relay.
The PA1000 provides the system integrator with a simple, convenient and economic solution
for the interconnection of modern high speed routers fitted with POS interfaces and older
legacy routers with HSSI interfaces.
