Highlights

Release 8, Issue 3.0 (03.0.042.2)

The TN2302AP circuit pack is supported by Release 8.3 software and replaces 
the TN802B Media Processor, with the following proviso.  The version of the 
circuit pack available coincident with Release 8.3 does not support fax.  The 
current release of the circuit pack is intended for configurations requiring IP 
station and trunk connectivity without fax.  The fax version of the circuit pack is 
targeted for release in September, 2000, and will work with the Release 8.3 and 
later versions of the DEFINITY software base.

The TN2302AP circuit pack is the next generation H.323 IP platform.  It is 
designed to terminate a variety of packet audio protocols in DEFINITY Release 
8.3.  The circuit pack includes a 10/100 BaseT Ethernet interface and supports an 
increased number of H.323 IP-compliant audio streams for IP endpoints.  

In its performance, the TN2302AP circuit pack provides improved voice quality in 
addition to less latency.  It performs echo cancellation, silence suppression, Dual 
Tone Multifrequency (DTMF, or Touch Tone) detection, and conferencing.  When 
used with Release 8.3 software, the circuit pack supports the following codecs, 
fax detection for them, and conversion among them:

■

G.711 (mu-law or a-law; 64 Kbps)

■

G.723.1 (6.3 Kbps or 5.3 Kbps audio)

■

G.729A (8 Kbps audio)

Three new maintenance procedures asssociated with the TN2302AP circuit pack 
have been developed.  These include:

■

IPMEPRO — Maintenance procedures for the TN2302AP circuit pack

■

MEDPRO — Maintenance procedures for TN802B circuit pack

■

MEDPROPT8 — These maintenance procedures monitor the health of the 
MEDPRO digital signal processors (DSPs)

For more detailed information on these maintenance procedures see What’s New 
in DEFINITY Enterprise Communications Server, Release 8.3 (Document 
555-233-754, Comcode 108725649, Issue 1, July 2000)

The Automatic Route Selection (ARS)/Automatic Alternate Routing (AAR) Dialing 
without Feature Access Code (FAC) feature allows the system to be administered 
so that callers can place Automatic Route Selection (ARS) and/or Automatic 
Alternate Routing (AAR) calls without first dialing the Feature Access Code (FAC).   
The flexibility added to support this capability is intended for and supported only 
for this described capability.  Systems with this feature active should not activate 
transfer out of the voice mail system.  Additionally, other adjuncts should be 
checked to verify that calls will not be allowed off-switch unintentionally.
