Lucent-provided endpoint consists of a service provider, an application layer
called the Telephony Manager, and a registration application. The service
provider terminates DCP signaling carried over TCP. The Telephony Manager
provides the GUI emulating the DCP set. The registration application handles
H323.RAS and is used to register and authenticate the endpoint with DEFINITY.
This group of modules is called Vphone. Note that the Vphone does not include
any type of audio path of bearer channel. The Vphone provides a DCP control
plane for an alternate bearer channel. Tha alternate bearer channel is provided
by either a native H.323 station or a POTS line or trunk. The Vphone is used only
in a dual-connect arrangement.
The Vphone supports some level of existing DCP maintenance in the form of
audits and updates.
This station type is not attached to a port board. Insertion of the station is not
driven by board insertion, rather it is driven by successful registration of the
endpoint. It is maintained via a set of explicit TCP/IP ping requests and errors
reported by the User Manger software, which terminates the H.323 signaling
portion of each endpoint. The MO follows standard mtce methodology and
supports test, busyout, release and status commands.
MEDPRO
The TN802B MedPro circuit board is used by the DOLAN (Definity on the LAN)
feature to provide voice over IP connectivity. The TN802B can run either:
■ R8.1 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. It communicates with other ITS
boxes or IP trunk boards.
■ the 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 TN799 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 NT 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 NT interface and the ITS software diagnostics.
The Media Processor application 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.
