Hospitality features nDo Not Disturb — MASI terminals cannot activate Do Not Disturb. Multimedia features nMultimedia Call Handling — DEFINITY MMCH users are not able to make H.320 calls to MASI terminals over the MASI link. Calls between MMCX terminals and MMCH terminals are voice only. Troubleshooting Verify proper operation using the following commands and follow normal escalation procedures to resolve any failures detected by the demand test. 1. Verify the DS1 trunk using the test board long command. 2. Verify the ISDN Signaling Group using the test signaling-group command. Also verify proper administration. 3. Verify the temporary signaling connection using the test tsc-administered command. Also verify proper administration.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 230 Multimedia Call Handling 9 Common error conditions If the cable from the ECS to the MMCX becomes disconnected, you should see alarms raised against ISDN-SGRP and UDS1-BD. In particular, you should observe ISDN-SGRP errors such as 769, 1793, and 257. To resolve, reconnect the cable and follow normal test procedures. If the far-end path termination number is incorrect, you should observe MASI-PTH error 513. To resolve, correct administration using the MASI Path Parameters form. If the Layer 3 TSC is not administered properly or is out of service, you should observe errors (but no alarms) raised against TSC-ADM. Verify the signaling group administration and follow normal escalation procedures for TSC-ADM. See the appropriate DEFINITY ECS Maintenance manual for more information. If the TSC fails to come up even through Layer 2 Signaling Group and below pass tests, you may run test tsc-administered to force a switch heartbeat test, or simply wait 5–10 minutes for the link to recover. This situation may happen if the switch is rebooted or if the MASI interface is administered before the MMCX is properly administered. You may want to use busy port and release port commands to unlock things if features are not working. Multimedia Call Handling Multimedia Call Handling (MMCH) enables users to control voice, video, and data transmissions using a telephone and PC. Users can conduct video conferences and route calls like a standard voice call. They can also share PC applications to collaborate with others working from remote sites. Operations in Basic or Enhanced modes There are two distinct levels of functionality: Basic and Enhanced. The Basic mode of operation treats a standard-protocol H.320 multimedia call as a data call. If the call is redirected, it is converted to a voice call. As a voice call, certain features are enabled, such as coverage, voice mail, and multiparty video conferencing. The Enhanced mode of operation allows a multifunction telephone to control a multimedia call as if it were a standard voice call. Spontaneous video conferencing, call forwarding, call coverage, hold, transfer and park, along with many routing features, are available to multimedia calls. Both modes of operation allow data collaboration between multiple parties using the T.120 standard protocol.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 231 Multimedia Call Handling 9 Definitions: MMCH features and components Multimedia call A multimedia call, for MMCH, is one that conforms to the H.320 and T.120 suite of protocol standards. These standards allow video-conferencing packages from different vendors to communicate with one another. The capabilities of the individual multimedia-endpoint package can vary, however. nAn H.320 call can contain voice, video and data. nThe bandwidth for MMCH calls is limited to 2 B-channels. Figure 9. MMCH multimedia complex Basic multimedia complex A Basic multimedia complex consists of a BRI-connected multimedia-equipped PC and a non-BRI-connected multifunction telephone administered in Basic mode. With a Basic multimedia complex, users place voice calls at the multifunction telephone and multimedia calls from the multimedia equipped PC. Voice calls will be answered at the multifunction telephone and multimedia calls will alert first at the PC and, if unanswered, will next alert at the voice station. A Basic multimedia complex provides a loose integration of the voice station and H.320 DVC system.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 232 Multimedia Call Handling 9 Enhanced multimedia complex An Enhanced multimedia complex consists of a BRI-connected multimedia-equipped PC and a non-BRI-connected multifunction telephone administered in Enhanced mode. The Enhanced multimedia complex acts as though the PC were directly connected to the multifunction telephone. Thus, voice call control, multimedia call control and call status are enabled at the telephone. An Enhanced multimedia complex provides a tight integration of the voice station and H.320 DVC system. Multimedia endpoint The multimedia endpoint is a user’s PC that has been equipped with an H.320 multimedia package. The PC is physically connected to the DEFINITY ECS with a BRI line. Figure 10. Enhanced MMCH service link Enhanced mode service link The service link is the combined hardware and software multimedia connection between the user’s multimedia endpoint and the DEFINITY ECS which terminates the H.320 protocol. The service link provides video, data, and, optionally, voice streams to augment the capabilities of the telephone and PC.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 233 Multimedia Call Handling 9 service link only applies to an Enhanced multimedia complex, never to a Basic multimedia complex. The service link is administered on the station form and can be either “permanent” or “as-needed.” Feature Description MMCH’s two levels of functionality for a multimedia complex, Basic and Enhanced mode, are enabled either by switch administration or by an mm-basic feature button or FAC. Basic Mode Operation In Basic Mode: nAll voice-only calls originate at the voice station. nAll multimedia calls originate with the H.320 DVC system. nAll incoming voice calls attempt to alert at the voice station and receive all standard voice call treatment. nAll incoming H.320 multimedia calls attempt to alert on the H.320 DVC system initially. If answered, a 2-way video call will result. The Basic multimedia complex voice station will not be involved in the call in any way. If the H.320 multimedia call is not answered at the H.320 DVC system and the Basic multimedia complex voice station has the H.320 field administered to “y”, the call will: — timeout at the DVC system — alert at the associated voice station set as a voice-only call — receive all standard voice call treatment. nCall control depends on what type of call is being originated. — Video is received and controlled at the PC. — Voice is received and controlled at the telephone set. nThe voice station of a Basic multimedia complex must manually add their multimedia endpoint to a multimedia conference. There is limited support for multimedia feature interactions. A specific set of voice features work for multimedia calls. nService Links are not used by Basic mode complexes. nA single number may be used to reach the Basic multimedia complex for voice or H.320 multimedia calls.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 234 Multimedia Call Handling 9 Enhanced Mode Operation The Enhanced multimedia complex provides a much more tightly coupled integration of the complex voice station and H.320 DVC system. In Enhanced Mode: nBoth multimedia and voice calls must originate at the telephone set. nVoice and multimedia calls can be controlled at the telephone set. nConferencing is spontaneous and established just like a voice-only conference call. nThere is extensive support for multimedia feature interaction. Most voice features work the same for multimedia calls. nService Links can be either “permanent” or “as-needed.” Physical Installation The physical components necessary to utilize MMCH capabilities include: nH.320 DVC systems that are BRI connected to the DEFINITY ECS. nNon-BRI multifunction telephones. nDEFINITY TN787 MultiMedia Interface (MMI) and TN788 Voice Conditioner (VC) boards. nA T.120 Enhanced Services Module (ESM) server (necessary only if you plan to do T.210 data collaboration). Connectivity of the ESM requires an additional TN787 along with a TN2207 DS1 circuit pack. Dual Port Desktop Both Basic and Enhanced multimedia complexes are dual-port desktops that consist of: na BRI-connected multimedia-equipped PC that supports the H.320 protocol na non-BRI-connected multifunction telephone set. The PC and the multifunction telephone are individually wired to the DEFINITY ECS. These two pieces of equipment can be administratively associated to form a Basic or ENHANCED multimedia complex MMCH works with any H.320 system that is fully H.320 compliant and operates at the 2B or 128K rate. NOTE: If you intend to share applications among users or whiteboard capabilities, the endpoint software you choose must also support the T.120 protocol.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 235 Multimedia Call Handling 9 The following endpoint-software packages have been tested: nPictureTel PCS 50 & PCS 100, Release 1.6T nProshare 2.0a, 2.1 nZydacron Z250 Ver. 2.02, Z350 Ver. 1.2 (With Netmeeting 2.0) MMI & VC hardware The MMCH feature requires the use of two additional circuit packs: nMulti Media Interface (MMI) TN787J. nVoice 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. nThese service circuit packs may be located in any Port Network. nThese packs do not require any translations as part of their implementation. nThe MMI and VC circuit packs are resource circuit packs akin to the Tone Detector circuit packs. nThese circuit packs require no switch administration and may be located in multiple port networks. nSpecific 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. T.120 Data Collaboration Server The Expansion Services Module (ESM) provides T.120 data collaboration capability on a MMCH multipoint H.320 video conference. nEach 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. nThe DEFINITY ECS must have an ESM installed.
