If the multiplexer is not equipped for module and line redundancy, there is an MA-215 or an MA-217B
behind the CM-5RB module. Both the MA-215 and MA-217B module adapters provide T1, remote port,
and timing connectors. However, the MA-215 adapter has an RJ-48C connector for the T1 circuit, and
the MA-217B adapter has a DB-15 connector for the T1 circuit. Figure 3-11 shows the pin locations on
both module adapter connectors.
