Description

The 8RS232 Interface Card for Loop-AM3440 has 8 interface ports. For the RJ version, 8 RJ48 connectors are
available in Asynchronous mode only. For the DB version, 2 RJ48 provide 2 ports and 2 DB44 connectors
provide 3 ports each. Two cables are included. Each cable converts from DB44 connector to two DB25 and
one DB9 connectors.
For Asynchronous signals, the card can be used in either INDEPENDENT mode or MUX mode. In the
INDEPENDENT mode, each of the 8 Asynchronous ports up to 19.2 Kb/s rate, is assigned a separate 64 Kb/s
channel. In the MUX mode, up to 5 ports, each up to 9.6 Kb/s, can share a single 64 Kb/s channel. The rest 3
ports will be multiplexed to another 64Kb/s channel.
For Synchronous signals, only four of the ports can be used, leaving another 4 ports as Asynchronous. In the
INDEPENDENT mode, each of the 4 Synchronous ports can be up to 64 Kb/s. The rest of the 4 Asynchronous
ports, each up to 19.2 Kb/s rate, is assigned a separate 64 Kb/s channel per port. In the MUX mode, the 4
Synchronous ports, each up to 9.6 Kb/s, share a single 64 Kb/s channel. The other 3 Asynchronous ports will be
multiplexed to another 64Kb/s channel.
The 8RS232 Interface Card uses the multiplexing format defined in ITU-T X.50 Div.2 and in X.54 for rates below
64kbps. For 64kbps transport, standard RS232 format is used. In the INDEPENDENT mode when only one
subrate signal is transported, the unused bandwidth is filled with "1s".
