Attaching Cables to the Analog Voice Module
The connections 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.
If your site requires an E&M connection, use an RJ-48C cable to connect
the Passport 4400 unit to a PBX. The strapping assignments for both 2-
wire and 4-wire cables are shown in Figure 6-20 on page 6-18.
Note:
Refer to Appendix E, PBX Interface Connection Diagrams
for
circuit connection information regarding connecting an E&M
voice channel to a PBX.
If your site requires an FXS or FXO connection, use an RJ-11 cable to
connect the Passport 4400 unit to a telephone set or wall jack.
Refer to Appendix A, Cable Diagrams, for further information about cables.
