DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 242 Multimedia Call Handling 9 Station screen After you have administered the BRI data module, use the Station screen to associate it with a voice station to screen a multimedia complex. This is a one-to-one relationship: you can administer only one station and one data endpoint per multimedia complex. Neither the voice station, nor the data endpoint can be a member of another multimedia complex. NOTE: A BRI station cannot be part of a multimedia complex. nH.320 Conversion — Valid entries are y and n (default). This field is optional for non-multimedia complex voice stations and for Basic multimedia complex voice stations. It is mandatory for Enhanced multimedia complex voice stations. Because the system can only handle a limited number of conversion calls, you may need to limit the number of telephones with H.320 conversion. Enhanced multimedia complexes must have this flag set to y. For non-multimedia complex voice stations, setting this field to y allows H.320 calls to convert to voice and alert at the stand-alone voice station. If the call is unanswered at the voice station, the call will follow standard voice treatment. Any subsequent station that is reached in the routing of this call, that is, coverage points, forwarded destinations, call pickup members, and so forth, do not need to have the H.320 field enabled. The H.320 field is only needed at the first station that may receive the H.320 call. For Basic multimedia complex voice stations, setting this field to y allows H.320 calls to convert to voice and alert at the Basic multimedia complex voice station after an attempt has been made to offer the call to the H.320 DVC system. If the call is unanswered at the H.320 DVC system, the call will alert at the voice station after 5 seconds or after the administered number of rings as specified in the voice station’s coverage path. If the call is unanswered at the voice station, the call will follow standard voice treatment. Any subsequent station that is reached in the routing of this call, that is, coverage points, forwarded destinations, call pickup members, and so forth, do not need to have the H.320 field enabled. The H.320 field is only needed at the first station that may receive the H.320 call. nService Link Mode — The service link is the combined hardware and software multimedia connection between an Enhanced mode complex’s H.320 DVC system and the DEFINITY ECS which terminates the H.320 protocol. A service link is never used by a Basic mode complex H.320 DVC system. Connecting a service link will take several seconds. When the service link is connected, it uses MMI, VC and system timeslot
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 243 Multimedia Call Handling 9 resources. When the service link is disconnected it does not tie up any resources. The Service Link Mode can be administered as either ‘as-needed’ or ‘permanent’ as described below: — As-Needed - Most non-call center multimedia users will be administered with this service link mode. The as-needed mode provides the Enhanced multimedia complex with a connected service link whenever a multimedia call is answered by the station and for a period of 10 seconds after the last multimedia call on the station has been disconnected. Having the service link stay connected for 10 seconds allows a user to disconnect a multimedia call and then make another multimedia call without having to wait for the service link to disconnect and re-establish. —Permanent - Multimedia call center agents and other users who are constantly making or receiving multimedia calls may want to be administered with this service link mode. The permanent mode service link will be connected during the station’s first multimedia call and will remain in a connected state until the user disconnects from their PC’s multimedia application or the DEFINITY ECS switch restarts. This provides a multimedia user with a much quicker video cut-through when answering a multimedia call from another permanent mode station or a multimedia call that has been early answered. nMultimedia Mode — There are two multimedia modes, Basic and Enhanced, as described below: —Basic — A Basic multimedia complex consists of a BRI-connected multimedia-equipped PC and a non-BRI-connected multifunction telephone set. When in Basic mode, 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 if it is administered with H.320 = y. A Basic mode complex has limited multimedia feature capability as described in ‘‘ Basic Mode Operation’’ on page 233). —Enhanced — An Enhanced multimedia complex consists of a BRI-connected multimedia-equipped PC and a non-BRI-connected multifunction telephone. The Enhanced mode station acts as though the PC were directly connected to the multifunction telephone; the service link provides the actual connection between DEFINITY ECS and the PC. Thus, voice and multimedia calls are originated and received at the telephone set. Voice and multimedia call status are also displayed at the telephone set. An Enhanced mode station allows multimedia calls to take full advantage of most call control features as described in ‘‘ Enhanced Mode Operation’’ on page 234.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 244 Multimedia Call Handling 9 nMultimedia Early Answer — Valid entries are y and n (default). This field lets you set this phone for early answer of multimedia calls. The system will answer the incoming multimedia call on behalf of the station and proceed to establish the H.320 protocol. After audio path has been established to the caller, the call will then alert at the voice station. The station may then answer by going off-hook and will have immediate audio path. No hourglass tone will be heard by the answering party (see ‘‘ Hourglass Tone’’ on page 255). Example: An administrative assistant who does not have a multimedia PC, but may get multimedia mode calls from forwarding or coverage, may want to set the H.320 flag to y and the early answer flag to y on their voice station. This allows any multimedia call to be presented to the station with immediate voice path rather than hourglass tone. The answered call could then be transferred as voice to voice mail or transferred as multimedia to a user equipped with a multimedia endpoint. Multimedia Buttons There are six new multimedia specific buttons that may be added to a voice station. Most of them may be placed on any voice station, whether it is part of a Basic multimedia complex, an Enhanced multimedia complex or not part of any multimedia complex. Two feature buttons, mm-basic and mm-pcaudio, may only be placed on stations which are part of an Enhanced multimedia complex. All of the multimedia specific feature buttons have a corresponding feature access code except mm-pcaudio and mm-cfwd. nThe mm-pcaudio feature can only be used via button. nThe mm-cfwd button may be replaced by the standard “call forward” FAC followed by the “multimedia call” FAC. nmm-call — This button may exist on any voice station. Most multimedia enabled users will want an mm-call button. This button (or it’s corresponding FAC) must be used to indicate that the user is placing a multimedia mode call. To place a multimedia mode call the user would go off-hook, select an idle call appearance, and press the mm-call button followed by the destination extension digits. If the user has a speakerphone they can simply press the mm-call button, which preselects an idle call appearance, followed by the destination extension digits. The mm-call button lamp lights when you press this button during call origination. The lamp also lights to indicate that the selected call appearance is a multimedia mode call.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 245 Multimedia Call Handling 9 nmm-basic — This button is only allowed on the voice station of a multimedia complex. The mm-basic button toggles a station between Basic and Enhanced modes. This button can NOT be used to change the station’s multimedia mode when the station has an active multimedia call appearance. Toggling between Basic and Enhanced mode changes the station’s administered Multimedia mode. When in Basic mode this field on the station form will show basic. When in Enhanced mode this field on the station form will show enhanced. The current station Multimedia mode will be saved to translation when a save translation command is executed. nmm-pcaudio — This button only works for an Enhanced multimedia complex voice station. When originating or receiving a multimedia call, the audio path is connected to the voice station’s handset or speakerphone device. The mm-pcaudio button allows a user to switch the audio portion of any call to their PC’s audio input/output device (if available). To switch the audio path to the PC while active on a call, the user presses the mm-pcaudio button (if off-hook you may now hang up the handset). The mm-pcaudio button’s status lamp will light up when the button is pushed to move the audio path to the PC and remain lit while the audio path is at the PC device. NOTE: If you are on a voice only call, the voice path will switch to the PC device but you will get muted or loopback video depending on the multimedia endpoint software. A user may simply go off-hook on their voice station or press the speakerphone button to move the audio path of a multimedia call from the PC back to the voice station. Pressing the mm-pcaudio button while the status lamp is lit and the voice station’s handset is on-hook will disconnect the user from the active call. nmm-datacnf — Pressing the mm-datacnf button from any voice station that is participating in a multimedia call will light the status lamp and alert the DEFINITY ECS that you want to enable T.120 data collaboration with the other parties on the call. The button status lamp will also light for other participants in the multimedia call who have mm-datacnf buttons. Pressing this button from the voice station that enabled data collaboration on a multimedia mode call will deactivate the data session and revert to a voice and video call. If you are participating on a multimedia call with data collaboration, but did not initiate the data collaboration, and you press this button, the status lamp led will flash momentarily and the T.120 data
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing multimedia calling 246 Multimedia Call Handling 9 services will not be terminated, (only the station that activated the collaboration session can deactivate it). This button only works for stations connected to a DEFINITY ECS equipped with an ESM adjunct. nmm-cfwd — The mm-cfwd button allows a user to indicate that multimedia mode calls will be forwarded as multimedia mode calls to a specific forwarded-to destination. If voice call forwarding is active and multimedia call forwarding is not active then multimedia calls going off of the DEFINITY ECS switch will be forwarded as voice only calls. The mm-cfwd button status lamp will be lit to indicate that multimedia call forwarding is activated. Pressing the mm-cfwd button when the lamp is lit will deactivate multimedia call forwarding. Note - pressing the mm-cfwd button is the same as dialing the regular call-fwd FAC followed by the mm-call button or FAC followed by the desired forwarded-to extension digits. nmm-multinbr — The mm-multinbr call button is similar to the mm-call button. It allows origination of a multimedia call from any voice station. It is used when the destination being dialed requires a different address for each of the 2 B-channels. An example of this is Central Office provided ISDN-BRI. This type of BRI line is provisioned with separate listed directory numbers for each B-channel. In order to make a 2B multimedia call to such a device, two sets of address must be entered. Originating a multimedia call with the mm-multinbr button will originate a call according to the Default Multimedia Parameters selected on the System Parameters Features form. This default parameter will be either 2x56 or 2x64. The bearer capability of the multimedia calls will either be 56K or 64K and the bandwidth will be 2B channels.
