IP Trunk 3.01 (and later) application

IP Trunk3.01 (and later) suppor ts ISDN Signaling Link (ISL) IP trunks on

the Media Card 32-port trunk card and the ITG-Pentium 24-port trunk card.

The NTCW80 8-port trunk card cannot be upgraded to IP Trunk 3.01 (and

later).

An ISDN Signaling Link D-Channel (ISL DCH) provides DCH connectivity

to the system and signaling control for the ports on the IP trunk card and

any additional ports on other IP trunk cards in the same node. The DCH

connection expands the signaling path betweenthe Meridian 1/CS 1000M

and the gateway. IP Trunk3.01 (and later) allows Meridian 1/CS 1000M

systems to be networked using ISDN, while transmitting H.323 signaling

and voice over a standard IP protocol stack.

IP Trunk3.01 (and later) compresses voice and demodulates Group 3 Fax.

IP Trunk3.01 (and later) then routes the packetized data over a private

IP network.

IP Trunk3.01 (and later) delivers an ISDN signaling interface between

the Meridian 1 and the Voice (and fax)over IP (VoIP) interface. The high

signaling bandwidth of this ISDN interface expands the featurefunctionality

for VoIPtrunks. It provides, for example, Calling Line Identiﬁcation (CLID)

and Call Party Name Display (CPND).

Toinstall IP Trunk 3.01 (and later), the customer must have a corporate IP

network with managed bandwidth capacity,and routers available for WAN

connectivity between networked Meridian 1/CS 1000 systems. The best

VoIPperformance is obtained with a QoS-managed network.

The LAN connection of IP Trunk 3.01 (and later) requires 10BaseT or

100BaseTX Ethernet network interfaces for voice (TLAN network interface)

and 10BaseT for management and D-Channel signaling (ELAN network

interface). There is no restriction on the physical medium of the WAN.

Non-compressing G.711 codecs require 100BaseT Ethernet network

connectivity. A 10/100BaseT auto-sensing Ethernet network interface

routes the voice trafﬁc from the IP trunk cards (TLAN subnet). Signaling

between cards and communication with the Optivity TelephonyManager TM

3.1 PC is transmitted over a 10BaseT Ethernet connection (ELAN subnet).

The application manages IP Trunk 3.01 (and later).
