Test Interface
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)
The Modem Management Network Module provides a single 6-pin modular jack. 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
The network connection follows, with the pinout shown in Table 12 below.
