G

T-Carrier

Atime-division, multiplexed digital transmission facility, usually operating at an aggregate data rate of 1.544 Mbps.

telnet

A remote terminal application that enables you to log on to a remote computer on the same IP network. You can work from the PC as if it were a terminal attached by a hard-wired line to the remote computer. The application uses the Telnet Internet protocol.

transmitter

In 64K mode, the transmitter inserts the frame bit, with a fixed pattern of 101100.

TRAP

A mechanism by which a device automatically sends an alarm for certain network events to a management station. The management station can initiate a polling sequence to the device to determine the cause of the problem.

U

UAS (Unavailable Seconds)

Number of seconds elapsed after 10 consecutive SES events are received (ESF framing only).

V

V.35

A CCITT standard for the trunk interface between a network access device and a packet network. It defines signaling for data rates greater than 19.2 Kbps.

V.52

Terminal emulation standard. CCITT standard (1976) for various loopback tests that can be incorporated into modems for testing the telephone circuit and isolating transmission problems. Operating modes include local and remote digital loopback and local and remote analog loopback.

V.54

A CCITT standard for loop test devices in modems. It defines local and remote loopbacks.
