Avaya 555-245-600 사용자 설명서

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.

The IG550, through its use of the TGM550 and TIMS, supports the following features:

●

●

Two built-in line ports to support two analog telephones or incoming analog DID
