Chapter 2 Module and Service Descriptions
ATM UNI Service Module (AUSM)
Table 2-3 contains a list of eight-port LED indicators:
Back Cards for the AUSM/B
The MGX-AUSM-8T1/B and MGX-AUSM-8E1/B use the generic eight-port T1 or E1 line modules that
operate with the eight-port service modules (see Figure 2-11).
• AX-RJ48-T1: provides eight RJ-48 connectors for T1 lines.
• AX-RJ48-E1: provides eight RJ-48 connectors for E1 lines.
• AX-SMB-E1: provides eight pairs of SMB connectors for E1 lines.
1:N Redundancy support for the AUSM requires the special versions of the RJ-45 back cards (see
Figure 2-11). These back cards are
• AX-R-RJ48-T1
• AX-R-RJ48-E1
• AX-R-SMB-E1
Note Redundancy support differs for the MGX-AUSM-8T1/B and MGX-AUSM-8E1/B. For details on the
requirements for redundancy through an MGX-SRM-3T3/C, see the ““Service Resource Module”
section on page 2-12.”
