These release notes describe the new features and caveats for all versions of Cisco Unified Videoconferencing 3515 MCU, Cisco Unified Videoconferencing 3545 MCU and Cisco Unified Videoconferencing 3545 EMP Release 188.8.131.52.54 and 5.5.3.
You can access the latest software upgrades and release notes for all versions of Cisco Unified Videoconferencing 3500 MCU on Cisco.com at the following URL:
The Cisco Unified Videoconferencing 3500 are high performance multipoint video conferencing and media processing systems that provide extensive audio and video processing capabilities and web-based conference monitoring and management.
Note Web user interface Conference Control functions are not supported for SCCP conferences.
The Cisco Unified Videoconferencing 3500 Series products support a wide range of telephony protocols and media communication networks and are interoperable with other video conferencing network devices.
Cisco Unified Videoconferencing 3500 Release 5.5 only operates with the following products:
•Cisco Unified Videoconferencing 3515 MCU12
•Cisco Unified Videoconferencing 3515 MCU24
•Cisco Unified Videoconferencing 3545 MCU
•Cisco Unified Videoconferencing 3545 EMP
You cannot install version 5.5 on older IP/VC products, or on the Cisco IP/VC 3510, 3511 and 3540 Series products.
Note You should use a Java-compliant browser. Using browsers other than the Microsoft Internet Explorer version 6 or 7 is strongly discouraged and is not supported.
Compatibility Matrix and Supported Upgrades
Upgrading from a previous build of MCU version 5.0 or 5.1 to MCU version 5.5.3
You cannot upgrade directly from MCU version 5.0 to version 5.5.3. Upgrade initially to version 5.1.1 and then to version 5.5.3.
Step 1 Save the current MCU custom configuration.
•Click Export on the MCU web user interface toolbar to export the MCU configuration to a *.ini file.
Step 2 Burn the MCU version 5.5.3 application with the MCU default configuration.
•Run the MCU v5.5.3 Upgrade Utility.
•Provide the target IP address, user name and password.
•Ensure that MCU Factory Default Configuration option is not selected.
•Ensure that all other Customize options are selected, including the Default MCU Configuration option but only one of the additional fonts if desired.
•Click Upgrade to perform the upgrade procedure.
•Wait while the MCU performs the upgrade procedure and resets.
Note This may take a few minutes. Please wait until the procedure is fully completed and the Upgrade Utility reports that the upgrade has been performed successfully.
Step 3 After reset, the latest version is installed on the MCU and the MCU configuration is set to the MCU Default Configuration.
Step 4 (Optional) Restore a previously saved MCU custom configuration.
•Click Import on the toolbar of the MCU web user interface to import a previously saved MCU version 5.x configuration .ini file.
Upgrading from a previous build of EMP version 5.0 or 5.1 to EMP version 5.5.3
Step 1 Use the EMP Upgrade Utility to burn the version of the EMP software that operates with the version of the MCU.
After burning, the Upgrade Utility will reset the platform.
Step 2 After reset, the latest version is installed on the EMP.
Downgrading from MCU version 5.5.3
We do not recommend downgrading from version MCU 5.5.3. If you need to downgrade, contact the Cisco TAC.

New and Changed Information
Cisco Unified Videoconferencing 3500 MCU Release 184.108.40.206.54 introduces the following features:
•High Definition Continuous Presence support.
•Double the port capacity for standard rate services on Cisco Unified Videoconferencing 3515 MCU12 and MCU24.
•HTTPS support in the web interface.
•MCU web interface supports Internet Explorer 7.
Cisco Unified Videoconferencing 3500 MCU Release 5.5.3 introduces the following features:
•Enhanced Lecture Mode now operates with HD mixed switched conferences.
Select one of the participants to be the lecturer. All other participants are considered students. The lecturer receives switched input from the students, either as Voice Activated or Auto Switched video. Students see the lecturer continuously.
•The switching interval in Auto Switched Mode is now configurable. Contact Customer Support for details.
•The video call rate is now restored to a higher rate once net problems are overcome.
•The Active Speaker indication now switches after 1 second only.
•Improved unit and web user interface stability, especially on high loads.
For information about all available features and benefits, see the data sheet for Cisco Unified Videoconferencing 3500 MCU at http://www.cisco.com/en/US/products/hw/video/ps1870/products_data_sheets_list.html.
Limitations and Restrictions
•When you enable High Definition Continuous Presence (HDCP) on either the Cisco Unified Videoconferencing 3515 MCU24 or the Cisco Unified Videoconferencing 3545 MCU, each EMP registered to the MCU automatically reserves 8 ports for HDCP from its available total of 24 ports.
When HDCP is enabled, only 12 ports are left available for SCCP partitioning on the first EMP. When SCCP port "spanning" over all EMPs is required, select the SCCP "All" formatting option. This option disables all non-SCCP protocols including HDCP functionality.
•The number of prefixed services defined in the MCU should not exceed 30. Defining a higher number of MCU prefixed services may prevent you from properly saving the MCU configuration to file.
•Subconferencing is not supported for SCCP services.
•The 4CIF picture size is supported for H.263 only.
Using Bug Toolkit
Known problems (bugs) are graded according to severity level. These release notes contain descriptions of the following:
•All severity level 1 or 2 bugs.
•Significant severity level 3 bugs.
•All customer-found bugs.
You can search for problems by using the Cisco Software Bug Toolkit.
Before You Begin
To access Bug Toolkit, you need the following items:
•Cisco.com user ID and password
Step 1 To access the Bug Toolkit, go to http://tools.cisco.com/Support/BugToolKit/action.do?hdnAction=searchBugs.
Step 2 Log in with your Cisco.com user ID and password.
Step 3 To look for information about a specific problem, enter the bug ID number in the "Search for Bug ID" field, then click Go.
For information about how to search for bugs, create saved searches, and create bug groups, click Help in the Bug Toolkit page.
The caveats in Table 1 describe possible unexpected behavior in the latest Cisco Unified Videoconferencing 3500 MCU releases. These caveats may also be open in previous releases. Bugs are listed in order of severity and then in alphanumeric order by bug identifier.

The following sections list caveats that are resolved but that may have been open in previous releases.
Bugs are listed in order of severity and then in alphanumeric order by bug identifier. Because defect status continually changes, be aware that this document reflects a snapshot of the defects that were resolved at the time this report was compiled. For an updated view of resolved defects, access the Bug Toolkit (see the "Using Bug Toolkit" section).
Table 2 lists the caveats that were resolved in Release 220.127.116.11.54.

In the "Enabling and Disabling High Definition Continuous Presence" section of the Configuration Guide for the Cisco Unified Videoconferencing 3545 MCU Release 5.5 (http://www.cisco.com/en/US/docs/video/cuvc/5_5/mcu/3545/configuration/guide/basic_v5_5.html#wp1054554), this information was omitted:
Note High Definition Continuous Presence is disabled by default. After enabling it, you must change service prefix 81 to 720p resolution. Enabling HDCP alone results in the service limiting the resolution to 4CIF.
