DEFINITY Switch Connectivity

1 Networking Overview

For IP Trunk connections, the voice data is sent over IP facilities as RTP datagrams using the IP Interface assembly (TN802 or TN802B) — each packet can potentially take a different route through the network. The call and DCS signaling data are sent as datagram packets over an IP network using the C-LAN interface. The R7 type of IP trunk (IP Interface operating in ip trunk mode) can also use tie-trunk PVC facilities for the DCS signaling.

Release 8 Hardware Requirements

For the three DEFINITY ECS switch models — csi, si, and r — Release 8 IP trunking (H.323) and IP Softphone connections require at least one IP Interface (TN802B) circuit pack and at least one C-LAN (TN799B) circuit pack. DEFINITY One requires only the IP Interface circuit pack.

IP Interface

The IP Interface assembly (J58890MA-1 L30) is a 3-slot wide TN802B circuit pack

 

that provides voice processing over IP connections. The IP Interface assembly

 

contains an NT processor, which is automatically administered by the DEFINITY

 

software. The TN802B can be administered to operate in medpro mode for H.323

 

trunks and IP softphones, or in ip trunk mode for R7-type IP Trunk connections.

C-LAN

The C-LAN circuit pack, TN799B, provides call setup, TSCs, QSIG, and DCS

 

signaling over IP connections.

 

Note: The TN799B must be used to handle call signaling for the TN802B in

 

MedPro mode. However, the previous version of C-LAN (TN799) can be

 

used for call signaling with the TN802 or the TN802B operating in IP

 

Trunk mode. The TN799 can also be used for DCS signaling connections

 

on a switch that is using the TN802B in MedPro mode, as long as there

 

are TN799Bs to handle the call signaling for the TN802B.

Hardware Requirements for Upgrades from Pre-R7 Switches

DEFINITY release 7 introduced several hardware changes that are also required for release 8. This section summarizes the hardware changes needed for pre-R7 switches upgrading to R8 for each switch model and each type of non-H.323 connectivity.
