Lucent-provided endpoint consists of a service provider, an ap plication layer
called the Telephony Manager, and a reg istration applicati on. The service
provider terminates DCP signaling carried over TCP. The Telephony Manager
provides the GUI emulating the DC P set. The registration application hand les
H323.RAS and is used to register and authentic ate the endpoint with DEFINITY.
This group of modules is calle d Vphone. Note that the Vphone does not inc lude
any type of audio path of b earer channel. The Vphone provides a DCP c ontrol
plane for an alternate bearer c hannel. Tha alternate bearer channel is provid ed
by either a native H.323 station or a POTS line or trunk. The Vphone is used only
in a dual-connect arrang ement.
The Vphone supports some level of existing DCP maintenance in the form of
audits and upd ates.
This station type is not attached to a p ort board. Insertion of the stati on is not
driven by board insertion, rather it is driven b y successful registration of the
endpoint. It is maintained via a set of explicit TCP/IP ping requests and errors
reported by the User Mang er software, which terminates the H.323 sig naling
portion of each endp oint. The MO follows standard mtce me thodology and
supports test, busy out, release and status command s.
MEDPRO
The TN802B MedPro circuit board is used b y the DOLAN (Definity on the LAN)
feature to provide voice over IP connec tivity. The TN802B can run either:
■R8.1 IP Trunk application — allows the TN802B to emulate a DS1 circuit
pack. In this mode, the c ircuit pack is maintain ed as a standard DS1
board with its associated Tie trunk ports. The TN802B operates as an
integrated Internet Telephony Server. It communicates with other ITS
boxes or IP trunk boards.
■the Media Processor (MedPro) applic ation — allows the TN802B to act as
a service circuit to termin ate generic RTP streams used to carry
packetized aud io over an IP network. As part of the overall H.323
implementation, the TN802B or later circuit p ack handles the aud io
streams while the TN799 C-LAN handles the TCP/IP signaling channels.
This maintenance plan app lies only to a TN802B MedPro running the
Media Processor applic ation.
The MedPro hardware combines an angel c omplex, a Windows NT PC and a
TAP802 DSP card in a 3-slot pac kage. When operating as an IP trunk circ uit
pack, the MedPro emulates a DS1 Tie Trunk circuit pack and blind ly responds to
DS1 trunk maintenance requests. Actual maintenanc e is accomp lished via the
windows NT interface and the ITS software diagnos tics.
The Media Processor applicat ion is built upon the existing ITS software, and as
such is not administered in DEFINITY as a DS1 trunk, and does not emulate a
DS1 for maintenance purposes.
