B.3.8 ASI I/O Option Card
The ASI I/O option card provides a means of outputting an MPEG-2 Transport
Stream over an ASI connection. Two outputs are provided which can be configured
as mirrored, such that the same TS is output from each connection, or independent,
such that a different TS is output from each.
Two input BNC connectors and associated lock LEDs are available for feeding the
unit with external Transport Streams.

Item Specification
Standard CENELEC EN50083-9 2002
Input Transport Stream format
188 byte or 204 byte. For 204 byte, the Reed-Solomon coding is
discarded and not acted upon.
Output Transport Stream format 188 byte
Safety Status SELV
Connector Designation ASI IN 1 / ASI IN 2 / ASI OUT 1 / ASI OUT 2
Connector Type 75 Ω BNC
Input Impedance:
(Resistive termination)
75 Ω
B.3.9 G.703 Transceiver Card
The G.703 Transceiver card provides one PDH (Plesiochronous Digital Hierarchy)
output interface that can be used for interfacing Transport Streams to PDH
networks. The interface is G.703 compliant, and can provide support for E carriers,
namely E31 (E3) and E32 (DS3) as specified in ITU-T Rec. G.703. The input
interface is not supported in this release.
Note: The G.703 Transceiver Card has an input interface, but the G.703 input is
not supported in this release.
