Cisco TelePresence Multipoint Switch Release 1.1 Administration Guide
OL-12586-02
Chapter 8 Interoperability with Legacy Video Conferencing Devices
Prerequisites
• CUVC participants will not experience the spatial audio generated by CTS. CUVC participants hear
all Cisco TelePresence participants mixed together in G.711.
• CUVC as an SCCP conference resource managed by Unified CM is not a supported option.The
CUVC must be defined as a SIP trunk (and optionally an H.323 gateway) to Unified CM.
• CTS participants hear CUVC participants mixed together in G.711; audio will be heard from the
same segment as that which is showing the CIF video.
• CTS and CUVC participants are not able to share slides or documents using H.239. Use another
application for document sharing between CTS and CUVC, such as MeetingPlace or WebEx.
• Far End Camera Control (FECC) is not available to CTS participants during an interoperability call.
• Each interop conference uses one CTMS port and one CUVC port for each conference because each
meeting utilizes a port for the cascade link. For example, CTMS normally can support 48 segments,
and CUVC-3515-24 can support up to 24 participants. During interop meetings, CTMS supports a
maximum of 47 segments and CUVC supports a maximum of 23 participants.
• Encryption is not supported for CTMS, Release 1.1, including interoperability calls.
Prerequisites
Interoperability between traditional video conferencing devices and CTS requires three components:
• CTMS
• Cisco Unified Communications Manager (Unified CM)
• CUVC MCU
The software and hardware requirements for Cisco TelePresence Interoperability are as follows:
CUVC Software and Hardware Requirements
• CUVC MCU Release 5.5.0.0.54:MP or later
• CUVC EMP Release 5.5.2.0.2:EMP or later
For additional information about configuring CUVC, refer to the Configuration Guide for the Cisco
Unified Videoconferencing 3545 MCU Release 5.5.
Unified CM Software Requirements
• Unified CM Software Release 6.0 or later
For additional information about configuring Unified CM for Cisco TelePresence System, refer to the
Cisco Unified Communications Manager Installation Guide for the Cisco TelePresence System.
For information about configuring Unified CM, refer to Cisco Unified Communications Manager
Version 6.0 and Cisco Unified Communications Manager Version 6.1.
CTS Endpoint Software Requirements
