Emergency transfer at the DEFINITY Remote Office 

The Avaya R300 Emergency Transfer feature provides some limited telephone service in 
the case of disaster. This feature enables a relay contact set to directly cut-through the tip 
and ring of the two analog station ports and to connect them to the two wire analog trunk 
interface. These two analog stations operate in a loop-start trunk mode (for example, go 
off-hook to seize an out-going CO trunk connection). See 

.

NOTE:
The DCP stations do not operate in this failure mode.

The Emergency Transfer relays operate by:

■

Loss of power on the Avaya R300’s Combo Blade

■

Failure of the Keep-Alive registration message, indicating loss of connectivity 
back to a main DEFINITY site.

The system management of the Remote Office consists of two functional subsystems:

■

DEFINITY main switch

■

Avaya R300 voice/data switch

The DEFINITY is managed for administration via a SAT interface and/or via the 
DEFINITY System Administration (DSA) or DEFINITY Network Administration (DNA) 
tools. The Lucent-Ascend Command Line Interface manages the administration of the 
Avaya R300. Within the Avaya R300, the TAOS operating system is designed to support a 
menu-driven administration system. This system provides for the full administration of the 
Avaya R300 Combo Blade’s voice features.
