2.5 Configuration 4
Configuration 4 is the data/voice/fax configuration with two MultiMux MMV1608C/56/V multiplexers with single composite link connecting a minicomputer and the station side of a PBX at the local site to a group of remote terminals and printer on the data part of the network and a telephone and fax machine on the remote voice/fax channels. This FXO to FXS configuration allows the remote site to communicate over the composite link to the local site and be able to use the local PBX facilities as if he/she were at the local site. The FXO to FXS configuration is shown in Figure
This configuration has the MV2 Voice/Fax board installed in the MMV1608/56/V multiplexers for the voice over data communications. The local site has the VOICE/FAX CHANNEL 1 and 2 FXO connectors on the back panel of the local multiplexer connected to a station card in the PBX. At the remote site, the two VOICE/FAX CHANNEL 1 and 2 FXS connectors on the back panel of the remote multiplexer are connected to a telephone and fax machine.
