Glossary
A theoretical means of describing visible light that is determined by comparing its hue with a heated
light temperature
black-body radiator. The lamp's color temperature is the temperature in kelvins at which the heated
black-body radiator matches the hue of the lamp.
Long Term Reference Picture.
LTRP
M
Media Access Control. A hardware address that uniquely identifies each node of a network.

MXE
P
An easily compressible video frame type. A video frame is compressed using different algorithms that
P-frame
allow varied amounts of data compression. These different algorithms for video frames are called
picture types or frame types. The three major picture types used in the different video algorithms are I,
P, and B.
Presentation-in-picture. Data or graphics content sharing through an external monitor known as
PiP
presentation-in-picture (PIP) format for space-constrained offices. You can toggle the position of the
PiP between center, left, or right locations on the screen. PiP is not present on the CTS 3000 or
CTS 3200 series.
Power over Ethernet.
PoE
The primary codec is the primary unit; it communicates with secondary units, sends and receives
primary codec
packets on the uplink network. It contains an onboard Gigabit Ethernet switch. For example, in a
CTS 3000 or CTS 3200 system, the primary codec controls two secondary codecs as well as many
system components and the graphical user interfaces. In a Cisco TelePresence 1000, it controls all
system functions.
Printed circuit board.

R
Request for Comments. Document series used as the primary means for communicating information
RFC
about the Internet. Some RFCs are designated by the
Cisco TelePresence System Release 1.6 Administration Guide
