Compatibility
Operating in non-native mode does not affect subscribers’ or outside
callers’ use of the system. System administrators, however, should be
aware that messages from the switch, such as alarms, that refer to a
TN754 or a TN2181 circuit pack the system is emulating may actually
refer to the DEFINITY AUDIX system.
NOTE:
Lucent Technologies strongly recommends that the DEFINITY
AUDIX system emulates a TN2181 digital port circuit pack in
switch versions 2 and later. A TN2181 emulation supports a
maximum of 12 voice ports, while a TN754 emulation only
supports a maximum of 8 voice ports. If the DEFINITY AUDIX
system emulates a TN2181 circuit pack, system expansion may be
easier. Switch versions earlier than 2 do not support TN2181
circuit pack emulation.

the DEFINITY AUDIX system and whether or not they support the system
in native mode. For more information about the TN568 circuit pack or the
system’s operations native and non-native mode, see Chapter 2

more information about Alarm Origination and the DEFINITY AUDIX
system’s interactions with the switch, see Chapter 3
