Procedure 9: Attaching cables to the Analog Voice Module
Note: The connections made in this procedure will depend on the specific site
requirements. If you are not sure of the exact connections required for the
Passport 4400 unit you are installing, consult your system administrator.
1. If your site requires an E&M connection for channel 1, use a modular RJ-1CX
cable to connect the Passport 4400 unit to a PBX. The pin assignments for
both 2-wire and 4-wire cables are shown in Figure 4-7.
2. If your site requires an FXS or FXO connection for channel 1, use a modular
RJ11 cable to connect the Passport 4400 unit to a telephone set or wall jack.
3. Connect Channel 2 (dual channel model only) using either step 1 or step 2,
depending on the requirements of the specific site.
