ASI CBR Module

The AP ASI CE interface module offers an unstructured ASI circuit emulation function to the Access Processor platform, enabling the convergence of ASI services into the ATM switch, e.g. video codecs and satellite modems. The ASI port unframed MPEG-2 transport streams, with a BNC connector pair. Transport stream rates from 600kbps to 52Mbps are supported, with a single transport stream supported per interface module. PID based multiplexed streams are not supported.

Unframed Data over Satellite

Data over Datellite using an ASI modem.

DVB Video over Satellite

DVB video over Satellite using a Remote Production Facility.

The incoming ASI data stream is segmented into ATM cells using unstructured AAL.1 adaptation. At the remote end, the ASI clock is recovered and the original bit stream is reassembled. End to end timing is maintained through the use of adaptive clocking and jitter attenuation.

These modules are "Hot Swappable" to ease maintenance, with replacement modules recovering immediately without further configuration.

This module collects and collates physical layer statistics including alarms and errors, whilst flexible clocking modes remove network synchronisation problems.

Management and configuration of this module is achieved via the simple menu driven user interface of the Access Processor which also supports SNMP traps.
