Cisco Unified Videoconferencing 3515 MCU Services

This section introduces services, describes how to work with them, and includes the following topics:

•About Services

•Working with Services on the 3515 MCU

•Configuring Advanced Management and Security for the 3515 MCU

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 four predefined services for audio and video conferencing, for use with the SCCP protocol and for use with Cisco Unified MeetingPlace. 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 the following 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

Configuring 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 Video in the Service type field.

Step 4 Click Add.

The Automatic Service Definition dialog box appears.

Step 5 Click the Advanced Video Settings button.

The High Definition Service dialog box appears.

The maximum call rate set in the Max call rate field of the Automatic Service Definition dialog box is displayed.

Step 6 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 7 Select a codec from the Codec field.

Step 8 To configure removal of the self image, select Enable `No Self See'.

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 7 Select a codec from the Codec field. Step 8 To configure removal of the self image, select Enable `No Self See'. Step 9 Click OK.
