Cabling your MultiFRAD 3000
Cabling your MultiFRAD involves general cabling connections for all models, data channel
connections, and Voice/Fax connections for models connecting to telephone equipment. The
general cable connections involve connecting power, command port, composite link device, and
LAN connections. The data channel connections involve connecting data devices, such as
multiplexers, or other MultiFRAD 3000s if you are using the hub feature. The final cable
connections involve connecting your telephone equipment to the voice/fax channels. The
following procedure details the cable connections for each type of connection.
Note: Before starting your general cable connections, perform the E&M Jumper Block
Positioning Procedure if a voice/fax channel will be connected to an E&M trunk that is Type 1,3,4,
or 5 rather than the default position of Type 2.
