Alarm Origination
In addition to the TN566 or TN567 multifunction circuit pack, previous
releases of the DEFINITY AUDIX system used a secondary circuit pack,
called an alarm board
. The alarm board diagnosed the DEFINITY AUDIX
system for trouble and posted active alarms for the system administrator
and Lucent Technologies’ Initialization and Administration System
(INADS). The TN568 circuit pack performs these functions on Release
4.0.
External Modem
In addition to the alarm board, previous DEFINITY AUDIX system
releases used an internal modem to notify INADS of active alarms and
provide the Remote Services Center (RSC) remote access to the system
for maintenance and alarm resolution. DEFINITY AUDIX system Release
4.0 uses an external modem to perform these tasks.
The change to an external modem helps reduce the space the system
occupies in the switch. It also improves the system’s flexibility for
meeting international communication standards.
Administration Impacts
Because DEFINITY AUDIX system Release 4.0 uses an external modem,
rather than an internal modem, customers can use a number of modems
with their DEFINTIY AUDIX systems.

If customers use a modem other
than the U.S. Robotics 33.6 Kbps Sportster modem—the default modem
for U.S. customers—the installer or system administrator must enter an
initialization string for the modem in the
System-Parameters-Maintenance screen during initial DEFINITY AUDIX
system administration.
NOTE:
Lucent Technologies does not provide maintenance support for
external modems other than the U.S. Robotics 33.6 Kbps Sportster
modem for the DEFINITY AUDIX system Release 4.0.
The system’s default initialization string corresponds to the U.S.
Robotics 33.6 Kbps Sportster modem. System administrators should
look for other modem initialization strings in the documentation for their
modems and enter these initialization strings manually. For more

Kbps Sportster modem in the U.S. and other countries where this
modem meets communication standards.
