1.3.1.1 Phone Multiplexer
Bull offers a Phone Multiplexer for domestic customer sites with multiple CDA 7
units (Integrated Remote Adaptor). The CDA 7 Phone Multiplexer consists of a
PBX with a Direct Inward Systems Access (DISA) board set that switches
incoming calls to the correct CDA 7 unit. The Phone Multiplexer allows any mix
of CDA units to use a common telephone line to communicate with the Bull
Competence Center. Each CDA 7 unit has its own extension in the Phone
Multiplexer network.
