Multimedia Call Handling 

The following endpoint-software packages have been tested:

■

PictureTel PCS 50 & PCS 100, Release 1.6T

■

Proshare 2.0a, 2.1

■

Zydacron Z250 Ver. 2.02, Z350 Ver. 1.2 (With Netmeeting 2.0)

The MMCH feature requires the use of two additional circuit packs:

■

Multi Media Interface (MMI) TN787J.

■

Voice Conditioner (VC) TN788B.

The TN787 and TN788 are service circuit packs. The TN787 supports 
simultaneous operation of 16 2B H.320 calls. The TN788 supports the voice 
processing for 4 H.320 endpoints. 

■

These service circuit packs may be located in any Port Network. 

■

These packs do not require any translations as part of their implementation. 

■

The MMI and VC circuit packs are resource circuit packs akin to the Tone 
Detector circuit packs. 

■

These circuit packs require no switch administration and may be located in 
multiple port networks.

■

Specific provisioning guidelines for the number and placement of these 
packs can be found by calling the Lucent Technical Support Center (TSC) 
at (303) 850 - 8187. 

The Expansion Services Module (ESM) provides T.120 data collaboration 
capability on a MMCH multipoint H.320 video conference. 

■

Each person in the conference who wants to participate in the data 
collaboration session, must have a personal computer with an H.320 video 
application that supports the T.120 protocol. 

■

The DEFINITY ECS must have an ESM installed.
