Step 4 Configure the dial plan for packet voice. Refer to Chapter 11, Dial Plan for
details on configuration (see Figure C-22).

Step 5 Connect the packet endpoint to the physical interface (see Figure C-23).

Example 5: Private Frame Relay Network—Packet Voice
Example 5 (see Figure C-24) shows a private frame relay network using
compressed voice. An ATLAS 550 is located at two sites (Atlanta and
Boston) and a PBX is connected to each ATLAS 550 using a clear-channel T1
connection. Each PBX uses DS0s 1—23 for voice and DS0 24 for signaling; all
calls are to be completely managed by the PBXs. In this network, the ATLAS
550 does not terminate the signaling information, but forwards the signaling
between endpoints using a transparent bit oriented protocol (TBOP) frame
relay connection (requires the Voice Compression Module). To re-create this
example, follow the process discussed below.
