Introduction - Avaya 6424D+M User Manual

Congratulations on the addition of an Asynchronous Data Module (ADM II) to your AT&T
Integrated Services Digital Network (ISDN) set. Following our tradition of excellent quality and
high reliability, the ADM is designed to provide you with the latest in telecommunications
technology (Figure 1).
AT&T's ISDN voice terminals with the addition of the ADM provide you with simultaneous
voice and data communications capabilities in one unit. As a telephone, the ISDN voice terminal
offers programmable buttons, fixed feature buttons, and a message indicator. The addition of the
ADM allows attached data terminals or personal computers to send and receive data through an
ISDN network. This user's manual applies to AT&T's third generation of ADM products,
referred to as Feature Package 3 (FP-3).*
* FP-3 is the first feature package designed for use with ADM II hardware. FP-1 and FP-2 were designed for use
with ADM I hardware. FP-3 can only be installed into an older FP-1 or FP-2 (ADM I) set if the ADM I circuit
board is replaced with an ADM II circuit board.
