IP Trunk 3.01 (and later) application
IP Trunk 3.01 (and later) supports 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 between the Meridian 1/CS 1000M
and the gateway. IP Trunk 3.01 (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 Trunk 3.01 (and later) compresses voice and demodulates Group 3 Fax.
IP Trunk 3.01 (and later) then routes the packetized data over a private
IP network.
IP Trunk 3.01 (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 feature functionality
for VoIP trunks. It provides, for example, Calling Line Identification (CLID)
and Call Party Name Display (CPND).
To install 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
VoIP performance 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 Telephony Manager TM
3.1 PC is transmitted over a 10BaseT Ethernet connection (ELAN subnet).
The application manages IP Trunk 3.01 (and later).
