trap
A Simple Network Management Protocol ( SNMP ) trap is a message which is initiated by a network
element and sent to the network management system. See the Cisco TelePresence System Message
Guide .
triple system
A Cisco TelePresence System featuring three display screens.
TFTP
Trivial File Transfer Protocol. Simplified version of FTP that allows files to be transferred from one
computer to another over a network, usually without the use of client authentication (for example,
username and password).
TIP
Telepresence Interoperability Protocol. The TIP Specification provides a protocol for interoperability
between videoconferencing products, including streaming of audio, video, and data to and from
videoconferencing products.
This feature adds TIP 7 support to the CTS and CTMS 1.7 release. The main purpose of the feature is
for CTS and CTMS to operate in a strict TIP V7 mode when communicating with devices advertising
TIP V7 support. This feature adds the ability to differentiate between MUX and TIP modes of operation
to help with the strict adherence to the TIP V7 specifications as well as improving debugging and other
operational processes. This feature adds the ability for the CTS to be configured for operation in a
TIP-only mode and configured with a set of media features typically not used in Cisco-only
deployments. This helps the CTS and CTMS inter-operate with third-party TIP devices.
TIP allows only endpoints with Restricted media settings to join Cisco TelePresence meetings. TIP
endpoints are expected to be able to send restricted media and to drop endpoints that can only transmit
un-restricted media. See the
Telepresence Interoperability Protocol for Developers home page on
Cisco.com.
U
UDI
Unique device identification.
V
VGA
Video Graphics Array port and cable for Cisco TelePresence. A CTS endpoint initiates a presentation
at any point by plugging the VGA Auxiliary cable into the CTS endpoint presenter's laptop, which
automatically shares from the presenter’s laptop. The last participant in the meeting to plug in their
laptop with the VGA cable shares their presentation using
PiP . See the Cisco TelePresence System User
Guide for more information about sharing presentations.
virtual machine
A virtual machine (VM) is a software implementation of a machine (a computer, for example) that
executes programs like a physical machine does. A system virtual machine provides a complete system
platform which supports the execution of a complete operating system (OS). See the
Cisco TelePresence System Commercial Express Installation Guide on Cisco.com for more
information.
VLAN ID
The identification of the virtual LAN, which is used by the standard IEEE 802.1Q. Being on 12 bits, it
allows the identification of 4096 VLANs.
