IV. PBX Trunk Side Replacement (Stripped POTS)
This section provides the admin with the AOS commands to provision the TA912/924 with the ISDN PRI
or T1 CAS PBX Trunk Side Replacement. The intent is to show the admin an example for how the
configuration would be performed using the CLI as a reference:
DSX-1 Options:
Separate DSX-1 DS0s each with their own phone number and own trunk group. This configuration will
only allow that one PBX phone number to use that one DSX DS0 for inbound calls. For outbound calls, the
PBX will have to be configured for that phone extension to always grab the same DS0. This way the
correct Caller ID number will be sent to the called party.
