Avaya 03-300430 User Manual

The Media Processor Port (MEDPROPT) MO monitors the health of the Media Processor 
(MEDPRO) digital signal processors (DSPs).
The TN802B MAP-D (Multi-Application Platform for DEFINITY) Media Processor circuit pack, 
the TN2302, and TN2602 Media Processor circuit packs provide the audio bearer channels for 
H.323 voice over IP calls. 

●

One TN802B circuit pack has one MEDPROPT media processing resource; that one 
TN802B MEDPROPT can handle 31 channels, for a total of 31 channels per TN802B. 
Note that the TN802B has 11 physical DSP devices but they are treated as one logical 
MEDPROPT by Communication Manager software. 
If the list ip-codec-set screen specifies only G.711 mu-law or G.711 a-law as the 

audio codecs, the TN802B MEDPROPT can service 31 channels. If any other codec type 
(G.723-5.3K, G.723-6.3K, or G.729) is administered, the TN802B MEDPROPT can service 
22 channels.

●

One TN2302AP has 8 MEDPROPTs; each TN2302 MEDPROPT has the processing 
capacity to handle 8 G.711 coded channels, for a total of 64 channels per TN2302. Note 
that early TN2302AP boards have eight physical DSP devices. Vintage 11 and later 
TN2302AP boards have two physical DSP devices. Both board configurations provide 
eight MEDPROPTs and a total of 64 channels. 
When only G.711 codecs are in use the TN2302AP has the processing capacity to handle 
64 channels. If only G.723/G.729 codecs are in use the TN2302AP has the processing 
capacity to support 32 channels. If a combination of G.711 and G.723/G.729 codecs are in 
use the number of channels supported will fall somewhere between 32 and 64. Use the 
list ip-codec-set command to display the administered codecs.

●

The capacity provided by the TN2602 is controlled by the Avaya Communication Manager 
license file and may be set at either 80 G.711 channels or 320 G.711 channels. Depending 
on the codecs used by individual calls the number of simultaneous calls supported will 
vary. The TN2602 supports G.711, G.729A, G.729AB, and G.726 codecs.

If individual DSPs on the TN802B or TN2302AP or TN2602 fail, the board remains in-service at 
lower capacity.
The MEDPROPT is a shared service circuit. It is shared between H.323 trunk channels and 
H.323 stations. An idle channel is allocated to an H.323 trunk/station on a call-by-call basis.
