MEDPROPT
The MEDPROPT maintenance object monitors the health of the MEDPRO digital
signal processors (DSPs).
The TN802B MAPD (Multi-Application Platform for DEFINITY) Media Processor
circuit pack provides the audio bearer channels for H.323 voice over IP calls.
One TN802B circuit pack has one MEDPROPT media processing resource.
Based on system administration of audio codecs, a MEDPROPT can handle
either 31 or 22 simultaneous channels of H.323 audio processing. If the
ip-parameters
form specifies only G.711 Mulaw or G.711 Alaw as the audio
codecs, the MEDPROPT can service 31 channels. If any other codec type
(G.723-5.3K, G.723-6.3K, or G.729) is administered, the MEDPROPT can only
service 22 channels.
The MEDPROPT is physically made up of 11 individual DSPs, but is treated
logically as one port. If individual DSPs on the TN802B MAPD fail, the
MEDPROPT 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.
AN-LN-PT (and TR-LN-BD)
The TN793B/TN2793B Analog Line circuit pack (w/ Caller ID), and the TN797
Analog Trunk and Line circuit pack both support this Maintenance Object.
The TN793B/TN2793B Analog Line circuit pack (w/ Caller ID) provides 24 ports
for voice terminals and supports both on-premises and off-premises analog
voice terminals.
The TN797 Analog Trunk and Line circuit pack provides 8 ports, each of which
may be administered in any of several ways, as described in maintenance object
TR-LN-BD.
NOTE:
The TN793B/TN2793B analog line circuit pack supports analog data
modules. When assigned, analog data modules provide access to the
NetPkt (TN794 circuit pack) data ports. To activate an analog data module
you must assign the port location on the data form and connect a modem
to the port. The analog data module can be used for connection to a CDR
output, or other adjuncts as needed. These ports are tested the same as all
other analog ports on the circuit pack.
