MEDPRO (Media Processor MAPD Circuit Pack)
S8700 | 8710 / S8500
The TN802B MedPro circuit board provides voice over IP connectivity. The TN802B can run
either the:
● IP Trunk application allows the TN802B to emulate a DS1 circuit pack. In this mode, the
circuit pack is maintained as a standard DS1 board with its associated Tie trunk ports. The
TN802B operates as an integrated Internet Telephony server (ITS). It communicates with
other ITS boxes or IP trunk boards.
● Media Processor (MedPro) application allows the TN802B to act as a service circuit to
terminate generic RTP streams used to carry packetized audio over an IP network. As part
of the overall H.323 implementation, the TN802B or later circuit pack handles the audio
streams while the TN799DP C-LAN handles the TCP/IP signaling channels. This
maintenance plan applies only to a TN802B MedPro running the Media Processor
application.
The MedPro hardware combines an angel complex, a Windows 2000 PC and a TAP802 DSP
card in a 3-slot package. When operating as an IP trunk circuit pack, the MedPro emulates a
DS1 Tie Trunk circuit pack and blindly responds to DS1 trunk maintenance requests. Actual
maintenance is accomplished via the Windows 2000 interface and the ITS software diagnostics.
The Media Processor application is built upon the existing ITS software, and as such is not
administered in Communication Manager as a DS1 trunk, and does not emulate a DS1 for
maintenance purposes. Use the following Maintenance procedures for this application.
