must administer the maximum number of voice ports the
 DEFINITY 
AUDIX system
 will allow.

 If the DEFINITY AUDIX system emulates a 
TN754 8-port circuit pack, the administrator or technician will need to 
administer 8 voice ports. On the other hand, if the DEFINITY AUDIX 
system emulates a TN2181 16-port circuit pack, the administrator 
should only administer 12 voice ports because that is the maximum 
number of voice ports the DEFINITY AUDIX system supports.

Migration Impacts
DEFINITY AUDIX system Release 4.0 may not be the best voice 
messaging solution for customers who use more than 12 voice ports on 
previous releases of the system. If these customers migrate to DEFINITY 
AUDIX system Release 4.0, they may experience a significant decline in 
the speed of their voice messaging service. These customers may 
consider migrating to an I
NTUITY messaging system. For more 
information about the I
NTUITY messaging system, see 
INTUITY Messaging 
Solutions
.
Digital Networking Port
DEFINITY AUDIX system Release 4.0 has one digital networking port, 
while previous releases of the system had two digital networking ports. 
Although this change has only minimal affects on high-speed Digital 
Networking traffic—DCP Mode 1 or DCP Mode 3 connections—this 
change significantly reduces the Digital Networking traffic the system 
can support with low-speed Digital Networking—DCP Mode 2 
connections.
For DCP Mode 2 connections, the following traffic limits apply:
■ The system can network with only 10 remote AUDIX nodes.
■ The system can accommodate no more than 100 local 
subscribers.
■ The system can accommodate no more than 10,000 remote 
subscribers.
Customers whose DCP Mode 2 Digital Networking traffic requirements 
exceed those for DEFINITY AUDIX system Release 4.0 should consider 
the I
NTUITY messaging system. For more information about DEFINITY 
AUDIX system Release 4.0 traffic guidelines, see Chapter 3
. For more 
3. This rule differs from previous system administration conventions 
where administrators were required to administer the maximum 
number of voice ports the
switch would allow.
