About Services
A service can be regarded as a conference template. A service is the mechanism that defines the qualities and capabilities of a conference. A service is identified by its prefix. The service prefix number is incorporated into the conference ID to specify the service for the conference. A description of the service indicates the main attributes of the service or the target use for the service.
The MCU comes with several predefined services: one service for the SCCP protocol, one service for Cisco Unified MeetingPlace, and the remainder for audio and video conferencing. The predefined services are factory tuned to be suitable in most cases for audio and video calls. We recommend starting with these services and modifying them as necessary to suit your needs.
When using an SCCP service, these limitations apply:
•No support for presentation view (Duo Video and H.239)
•No support for T.120 data collaboration
•No support for H.235 encryption
•Maximum resolution supported is CIF
•Maximum call rate supported is 768 Kbps
•The G.722.1 and G.723 audio codecs are not available
•No support for conference PINs
•No support for dial out

About Customizing Services
You customize a service by first creating a new default service and then configuring your own settings in the Automatic Service Definition dialog box.
Configuring the Maximum Call Rate
You can configure the maximum call rate (bit rate) for audio and video. This is the maximum bit rate available for this service. This value represents the total bit rate of the voice, video and data streams combined, up to a maximum of 2 Mbps per call.
Procedure
Step 1 In the Administrator interface, on the sidebar, click MCU (if not already selected).
Step 2 Click the Services tab.
Step 3 Click Add.
The Automatic Service Definition dialog box appears.
Step 4 In the Max call rate field, select the maximum call rate for the voice, video and data streams combined.
Step 5 Click Upload.
Note A minimum call rate is defined automatically for each service; this minimum call rate can be changed by an advanced administrative command.
In the case of the high definition service, if a user joins a conference at a call rate that is below the defined minimum for the service, the MCU will consider the call a standard definition call.
The maximum call rate is adjusted dynamically to the lowest maximum call rate of all the participants in a conference, as long as that rate is not below the minimum call rate.
Configuring the Maximum Layout
The Max Layout field indicates the video layout displaying the maximum number of participants to which the conference view expands.
The choice of layouts for the service depends on the type of processing mode. The default layout is 1+7 participants.
Procedure
Step 1 In the Administrator interface, on the sidebar, click MCU (if not already selected).
Step 2 Click the Services tab. Select the service you wish to configure and click Add.
The Automatic Service Definition dialog box appears.

Configuring Switched High Definition Advanced Video Settings
In the Advanced Video Settings dialog box you can configure the video codec, video image size, participant layout options, theme and additional layouts for a particular service.
Procedure
Step 1 In the Administrator interface, on the sidebar, click MCU (if not already selected).
Step 2 Click the Services tab.
Step 3 Select High Definition Switched Video in the Service type field.
Step 4 Click Add.
Step 5 Select HD Switched Video from the Service Type field.
Step 6 Click Advanced Video Settings.
The maximum call rate set in the Max call rate field of the Automatic Service Definition dialog box is displayed.
Step 7 Set a value in the Allow call rate drop down to option.
This option enables you to configure the minimum bandwidth to which the MCU lowers a conference to enable additional endpoints to join. This form of "downspeeding" contributes to a higher percentage of call completion on the network. Endpoints are prevented from joining a conference at a bandwidth rate below the value set in this option.
After downspeeding occurs, the MCU automatically raises the conference bandwidth rate when the endpoints participating at the lowest bandwidth rate leave the conference. For example, in a conference of endpoints communicating at 768 Kbps and a value of 512 Kbps configured in the Allow call rate drop to option, the MCU lowers the conference to 512 Kbps when an endpoint attempts to join the conference at 512 Kbps. If that endpoint later disconnects from the conference, leaving two endpoints capable of communicating at 768 Kbps, the MCU automatically increases the bandwidth of the conference back to 768 Kbps.
Step 8 Select a codec from the Codec field.
Note H.264 must be a selected codec when the maximum layout definition is 720p.
Note The no self-see display is not available for high definition participants, even if the no self-see option is enabled.
Step 9 (Optional) Select Enable auto-switch every n seconds and enter the required interval.
Step 10 (Optional) Select Enable lecturer mode to enable all participants to see the lecturer in full screen, while the conference lecturer sees all the other conference participants in the selected layout while speaking.
Step 11 Click OK.
