Evolution from circuit-switched to IP

Phase 2: IP-enable the Port Networks to support IP endpoints

Port Networks, with the addition of IP enabling circuit packs, are able to serve as Media Gateways, representing the integration of IP and TDM telephony.

IP-enabling the existing system incrementally for IP endpoint support requires the following circuit packs:

●TN799DP Control-LAN (C-LAN) for IP call signaling.

●TN2602AP IP Media Resource 320 and TN2302AP IP Media Processor for IP audio media processing, including media streams that are intended for IP Softphones and IP Telephones. Two per port network, maximum.

Signaling and bearer communication can connect through both the traditional TDM/center stage route and the IP network infrastructure. This gentle migration to IP Telephony

(Figure 44: IP-enabled DEFINITY configuration) might have minimal impact on an existing, non-IP system, while simultaneously enabling all new IP endpoints to fully access all the Communication Manager features.

Note:

If Phase 2 is implemented before Phase 1, the system will resemble

Figure 44: IP-enabled DEFINITY configuration. Also, a system that implements Phase 2 but not Phase 1 cannot support as many IP endpoints as a system that implements both Phase 1 and Phase 2.
