The TGM550 module inserts into any slot in the J4350 or J6350 router and delivers a rich telephony feature set to the
branch office. This feature set includes:
• Central Avaya Communication Manager (and other communications applications) access
• Call center agent support
• 6-party meet-me conferencing
• Local survivability in the event of a WAN failure
• Local music-on-hold and voice announcements
• Full encryption of voice traffic
The TGM operates as any other Avaya H.248-based gateway and includes a two analog trunk/two analog station
module, modular Digital Signal Processors (DSPs), and a memory expansion slot.
There is a choice of several TIMs with analog: T1/E1/PRI and BRI options. The TIM514 analog module contains 4
trunks (FXO) and 4 stations (FXS); the TIM510 DS1 module supports T1/E1 and ISDN PRI; and the TIM521 module
supports 4 ISDN BRI interfaces.
