The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be
determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Modifications to this product not authorized by Cisco could void the FCC approval and negate your authority to operate the product.

The Cisco Unified Videoconferencing 3515 MCU supports devices that can send and receive video
streams, as well as those that cannot send but only receive video streams. This means that terminals
without a video camera or video capturing capabilities can participate in a conference as voice-only
participants while benefiting from seeing the other participants.

About Cisco Unified Videoconferencing 3515 MCU Topologies
The Cisco Unified Videoconferencing 3515 MCU can work in a centralized or cascaded topology. This
section describes these two options.
Centralized Topology

Cascaded Conferences
The Cisco Unified Videoconferencing 3515 MCU allows you to combine two or more conferences
resulting in a larger conference with many more participants. This is called cascading. Cascading creates
a distributed environment that helps reduce the drain on network resources. In addition, the processing
resources required by the
participating MCUs. Costly telephone or ISDN line usage can be further reduced with the mediation of
a gateway.
OL-17012-01
Cascading occurs when one conference with “x” number of participants invites another conference with
“y” number of participants. The two conferences effectively become one large conference. The
bandwidth required across a cascaded conference link is only that of one audio/video stream between
the two conferences. This is significantly less than the accumulated bandwidth of all the participants.

Physical Description
Each Cisco Unified Videoconferencing 3515 MCU unit internally contains two cards:
• Signaling and audio card (MCU—the upper card)
• Video processing card (EMP—the lower card)
The two cards work together to perform audio and videoconferencing, but each card requires a unique
IP address. The cards communicate with each other using IP as the backbone.
Note For correct operation, the EMP card must register with the MCU.
This section provides a physical description of the Cisco Unified Videoconferencing 3515 MCU12 and
Cisco
Unified Videoconferencing 3515 MCU24 units.
The Cisco Unified Videoconferencing 3515 MCU unit has a 10/100BaseT Ethernet port on the front
panel that uses an RJ-45 connector to connect to the network. There is an asynchronous, 9-pin serial-port
that you can use with a hyperterminal program to configure and monitor the module.
Figure 2-1 shows the front panel of the Cisco Unified Videoconferencing 3515 MCU unit. Ta b le 2-1
