Test Interface
This module contains two test interfaces:
NETWORK
and
MON
. The
NETWORK IN
and
OUT
Bantam test
jacks provide intrusive test capability for the incoming E1. By connecting test equipment to these jacks, the
E1 connection breaks and the test equipment terminates the incoming E1. The
MON IN
and
OUT
Bantam
test jacks provide a bridged access jack for nonintrusive monitoring of the incoming E1. When connected
to this jack, configure the test equipment for bridged termination.
Modem Management Network Module (P/N 1200341L1), USOC RJ-11C
The Modem Management Network Module provides a single 6-pin modular jack (RJ-11C) (see Table 10
for the pinout). The Modem Management Network Module provides the following functions:
• V.34, V.32bis, V.32, V.22, V.23, and V.21 data modulation schemes
• Connection rates from 2400 to 33.6K baud
• V.42 LAPM, MNP 2-4, and MNP 10 error correction methods
• V.42bis and MNP 5 data compression algorithms
