Administration for Network Connectivity
555-233-504 — Issue 1 — April 2000 CID: 77730
2 H.323 Trunks
This chapter describes how to set up and perform initial administration of IP Trunks between
DEFINITY ECS switches and between DEFINITY and non-DEFINITY switches that support the
H.323 V2 signaling protocols. The IP trunk connections described in this chapter use the TN802B
circuit pack in the MEDPRO mode. See Appendix F for administration of trunk connections that
use the TN802 or TN802B in the IP Trunk mode.
Overview
This section provides a summary of DEFINIY IP Solutions for DEFINITY ECS Release 8.2.
IP Solutions
DEFINITY ECS IP Solutions provide TCP/IP connectivity for two types of trunks and three types of IP
Softphones. On DEFINITY ECS,
IP Solutions use the TN802B IP Interface assembly for voice processing and the
TN799B C-LAN for signaling. The TN802B IP Interface includes a Windows NT server that resides on the
TN802B circuit pack inside the DEFINITY ECS.
The TN802B IP Interface, introduced in Release 8, can be administered to operates in either the MedPro mode
(for H.323-compliant ISDN PRI-equivalent trunk connections) or IP Trunk mode (for DS1-emulation
connections). It will typically be used in the MedPro mode. The IP Trunk mode is provided for compatibility
with existing R7 IP Trunk connections.
The TN802 IP-Interface introduced in Release 7, which operates only in the IP Trunk mode, can be upgraded via
firmware download to the TN802B.
The following table lists the IP Solutions configurations and the circuit packs and software used with each.
