Configuring the Remote Gateway 9150 unit Standard 3.1
Bridge Ports
Bridge Ports provide integration between the host PBX dialing plan and the
Remote Gateway 9150 unit local dialing plan. To determine the correct Bridge
Port configuration for your particular Remote Gateway 9100 Series network,
you must first consider the resource usage of both the Remote Gateway 9150
unit and RLC. The examples on pages 216 through 219 illustrate the most
common resource usage scenarios in a Remote Gateway 9100 Series network.
Configure a Bridge Port TN on the host PBX as a voice port. For further
information, refer to the Reach Line Card Installation and Administration Guide
(NTP 555-8421-210).
Terminology
In the following configuration examples, a local call is defined as a call that
terminates on a Local Calling key of a digital telephone set connected to a
Remote Gateway 9150 unit. This call can be from another local user, or an
inbound call from the PSTN through the BRI circuits on the Remote Gateway
9150 unit. The primary DN is the first key on the digital telephone set connected
to Remote Gateway 9150 unit that has a DN provided by the host PBX.
Notes:
1. Bridge Ports use the remote PBX DNs of Local and Remote digital
telephone sets connected to Remote Gateway 9150 units to transfer local
calls to the host PBX or to conference host PBX calls to local calls. At least
one remote PBX line key must be idle for the Bridge Port to function
properly.
2. You must ensure that both sides of the connection release when the calling
party terminates a call on a Bridge Port in order for the Bridge Port to
release.
