Preface

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.

Severity 1 (S1)—An existing network is “down” or there is a critical impact to your business operations.
You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operations are negatively affected by inadequate performance of Cisco products. You and
Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired while most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Chapter 1 Cisco Unified Videoconferencing 3545 MCU Functionality

Port Capacities of the 3545 MCU

The Cisco Unified Videoconferencing 3545 MCU can be configured to support a wide range of audio
and/or video ports.

The Cisco Unified Videoconferencing 3545 MCU supports switched High Definition video service
types. HD services enable Voice Activated single-screen displays at up to 2 Mbps, and offer resolutions
of 1280 x 720 pixels (720p) and 1920 x 1080 pixels (1080p).

HD service types also enable you to set a minimum downspeeding bandwidth rate which is common to
all endpoints participating in a conference.

Cisco Unified Videoconferencing 3545 MCU conferencing includes two types of cards:

• Cisco Unified Videoconferencing 3545 MCU—An MCU card that is responsible for the signaling

and the audio. When working alone, this card can only do audio conferencing of 96 audio ports. It
can be mixed and matched with up to four EMP cards to create a 96 flat port video bridge. The
Cisco Unified Videoconferencing 3545 MCU card has no video capabilities.

• Cisco Unified Videoconferencing 3545 EMP Enhanced Media Processor (EMP)—A video

processing card that can support 36 standard rate video ports (up to 384 Kbps) or 24 high rate video
ports (up to 2 Mbps).
