primary codec
The primary codec is the primary unit; it communicates with secondary units, sends and receives
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.
PCB
Printed circuit board.
R
RFC
Request for Comments. Document series used as the primary means for communicating information
about the Internet. Some RFCs are designated by the
IAB as Internet standards.
S
scheduled meeting
Multipoint TelePresence meetings are scheduled by end users using Microsoft Exchange or IBM
Domino clients in the same manner that a
point-to-point meeting is scheduled. Scheduled meetings
require no CTMS administrator interaction. CTS Manager is a required component for scheduled
meetings. It provides the interface between Microsoft Exchange or Lotus Domino and the CTMS,
allowing the appropriate resources on the CTMS to be reserved for the
multipoint meeting .
screen resolution
The fineness of detail that can be presented in the image on the CTS main display screen.
Recommended screen resolution for Cisco TelePresence is 1024 x 768.
SD
Standard definition display.
secondary codec
Codecs that assist the primary codec in the large Cisco TelePresence 3000/3200 systems. Secondary
codecs process audio and video signals and send them to the primary codec, which multiplexes the
signals into separate, single RTP streams.
Self View
Enables you to see yourself on the main display before your meeting starts.
single system
A Cisco TelePresence System featuring a single display screen.
SHA
Secure Hash Algorithm. A set of cryptographic hash functions designed by the National Security
Agency (NSA) and published by the NIST as a U.S. Federal Information Processing Standard. The
three SHA algorithms are structured differently and are distinguished as SHA-0, SHA-1, and SHA-2.
SIP
Session Initiation Protocol. Protocol designed to signal the setup of voice and multimedia calls over IP
networks.
SNMP
Simple Network Management Protocol. Network management protocol used almost exclusively in
TCP/IP networks as a means to monitor and control network devices, and to manage configurations,
statistics collection, performance, and security. See the
Cisco TelePresence System Message Guide .
SOAP
Simple Object Access Protocol. XML-based protocol to let applications exchange information over
HTTP.
spirit level
Spirit level or bubble level is an instrument designed to indicate whether a surface is level or plumb. A
spirit level is included with the CTS 1300 camera kit.
