proprietary CALL SETUP, CONNECT, ANSWER, and RELEASE packets. The
payload circuit is used to transfer packets containing the actual compressed
voice data.
• Destination Type specifies whether the destination node is on another
2212/9783 (Remote) or a another voice port on the same 2212 (Local).
4.2.3 Sample Scenario of 2212 with PBX and PSTN
For this sample configuration, two IBM 2212 routers are configured in a
back-to-back frame relay configuration to allow the following connectivity:
• To call from digital phone with 2212-B PBX (160-101) to 2212-A PSTN
(0120-366-435)
• To call from digital phone with 2212-B PBX (160-101) to 2212-A analog phone
(130-111)
• To call from 2212-A analog phone (130-111) to digital phone with 2212-B
(160-101)
We cannot call from 2212-A PSTN to 2212-B PBX digital phone, because FXO
can receive dial tone but cannot supply a dial tone.
