IG550 Integrated Gateway
The IG550 Integrated Gateway is a part of Avaya’s growing solutions for extending
Communication Manager communication capabilities from the headquarters of an organization
to all collaborative branch locations.The IG550 Integrated Gateway is an H.248 media gateway
that combines Avaya’s high-performance telephony and Voice over IP (VoIP) communications
with the sophisticated routing capabilities of the Juniper J-Series Services Routers.
Detailed description
The IG550 consists of the TGM550 Telephony Gateway Module (TGM550) and Telephony
Interface Modules (TIMs). The IG550 is inserted into either a Juniper J4350 or J6350 Services
Router. The IG550 is also connected over a LAN or WAN to an Avaya media server running
Communication Manager. Therefore, Avaya S8700, S8710, S8720, S8500, S8400, and S8300
Media Servers are able to provide the same top quality telephony services to the small branch
office as to the headquarters of the organization. As a result, the IG550 provides full feature
support for IP and analog telephones.
The IG550 is designed for use in a 20-to-100 user environment, with optimal performance at
branch offices with 20 to 80 telephones.
The IG550 features Standard Local Survivability (SLS). SLS provides partial backup media
gateway controller (MGC) functionality in the event that the connection with the primary MGC is
lost.
In addition to advanced and comprehensive telephony services that are provided by the
TGM550, the Juniper J-series Router, either the J4350 or J6350, provides full data networking
services, precluding the need for a WAN router. The J-series routers use Juniper Physical
Interface Modules (PIMs) for the hardware components to support network and routing
features. The J-series routers also provide Ethernet connections to a separate Ethernet switch
that IP phones connect to.
