Figure 7.7 ASI I/O Option Card
7.5.2 Interfaces
The ASI I/O option card has the following interfaces:
•
Two 75
Ω female BNC input connectors.
•
Two 75
Ω female BNC output connectors.
The input connectors are used for feeding the unit with external Transport Streams
that can be passed through the unit unmodified to an available output, or services
from the TS remuxed into a TS configured for an available output.
The output connectors can be configured as a mirrored output pair (with the same
Transport Stream on both outputs) or two independent outputs (with different
Transport Streams on each output).
Note: When the outputs are configured as independent the maximum bit rate of
the combined outputs must not exceed 200 Mbps.
7.6 G.703 Transceiver Card
7.6.1 General
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 provides 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.
The G.703 Transceiver Card uses the 27 MHz System Clock Reference (SCR)
signal from the base chassis as its frequency reference. The output bit rate of the
card can be 34 384 kbps (E31) or 44 736 kbps (E32). For the E3 carrier no framing
is supported. For the DS3 carrier M13 and C-bit frame structures are supported. If
C-bit framing is selected the output can be encapsulated in ATM packets.
Notes: M13 is the same as M23, C-bit is the same as C-bit Parity.
E3 is the same as E31, DS3 is the same as E32.
