black screen codes
System status information messages that appear on the main display screen before your meeting starts
and while the screen is still black. For example, “Please wait, you are the first meeting participant.”

BPDU
Bridge Protocol Data Units. Data frames that exchange information about bridge IDs and root path
costs. A bridge sends a BPDU frame using the unique MAC address of the port as a source address, and
a destination address of the Spanning Tree Protocol (STP) multicast address 01:80:C2:00:00:00.
C
CCP
The Conference Control Protocol (CCP) is an interface between the CTS and the CTMS that controls
the following elements of a Cisco TelePresence conference:
•
Locks a meeting.
•
Sets the switching policy.
•
Sends end meeting notifications.
•
Obtains the roster list.
•
Requests to meeting to be extended.
•
Sends black screen messages. See
black screen codes
.
•
Allows you to specify default outbound http proxy route.
CIF
Common Intermediate Format. A video standard that provides 352x288 pixels, or picture elements, of
video resolution.
Cisco CTI Manager
CTI Manager is required in a cluster for applications that use TAPI or JTAPI Computer Telephony
Integration (CTI). The CTI Manager acts as a broker between the CTI application and the Cisco Unified
Communications Manager Service. It provides authentication of the application and enables control or
monitoring of authorized devices. The CTI application communicates with a primary CTI Manager and,
in the event of a failure, will switch to a backup CTI Manager. The CTI Manager should be enabled
only on call processing subscribers, thus allowing for a maximum of eight CTI Managers in a cluster.
Cisco recommends that you load-balance CTI applications across the various CTI Managers in the
cluster to provide maximum resilience, performance, and redundancy.
Cisco Unified
Communications
Manager
Cisco Unified CM. Application that extends enterprise telephony features and capabilities to packet
telephony network devices such as IP phones and multimedia applications. Open telephony application
interfaces make possible services such as multimedia conferencing and interactive multimedia response
systems.
codec
Contraction of coder-decoder. Integrated circuit device that typically uses pulse code modulation to
transform analog signals into a digital bit stream and digital signals back into analog signals.
CTS device
Cisco TelePresence System (CTS) device: CTS 500, CTS 1000, CTS 1100, CTS 1300, CTS 3000
series, CTS 3200 series.
