Glossary

TDM	Time Division Multiplexer. A device that enables the simultaneous transmission of
	multiple independent data streams into a single high-speed data stream by
	simultaneously sampling the independent data streams and combining these samples to
	form the high-speed stream.
TMp	Trellis Multipoint. Paradyne's proprietary high speed, fast poll multipoint modulation
	scheme.
Top-Level menu	The very top of the menu tree that displays modem status and all Top-Level menu
	branches.
training	A process where two modems try to establish a connection over the VF line.
trellis-coded modulation	A modulation scheme developed by Paradyne which uses Forward Error Correction for
	multipoint and high-speed point-to-point applications.
tributary modem	Tributary modems in a network receive data from the control modem, as well as from the
	network management system in the network.
UL	Underwriter's Laboratories, Inc.
UNIX Dial	A factory preset configuration area containing the configuration options most often used
	in a UNIXr dial network.
upstream modem	A device connected ªcloserº to the host computer.
USOC	Universal Service Ordering Codes.
V.22	A CCITT standard for modems operating full-duplex over dial networks at 1200 bps.
V.22bis	A CCITT standard for modems operating full-duplex over leased lines or dial networks
	at 2400 bps.
V.27bis	A CCITT standard for modems operating over leased lines at 2400 or 4800 bps.
V.29	A CCITT standard for modems operating over leased lines at 4800, 7200, or 9600 bps.
V.32	A CCITT standard for modems operating full-duplex with asynchronous or synchronous
	data over leased lines or dial networks at 4800 or 9600 bps.
V.32bis	A CCITT standard for modems operating full-duplex with asynchronous or synchronous
	data over leased lines or dial networks at 4800, 7200, 9600, 12,000, or 14,400 bps.
V.32 terbo	A modulation that adds the 19,200 bps and 16,800 bps data rates to the V.32bis data
	rates. It is a Paradyne proprietary modulation, not a CCITT standard.
V.34	A CCITT standard for modems operating full-duplex with asynchronous or synchronous
	data over leased lines or dial networks at 28,800, 26,400, 24,000, 21,600, 19,200, 16,800,
	14,400, 12,000, 9600, 7200, 4800, 2400 bps.
V.42	A CCITT standard for error control protocol.
V.42bis	A CCITT standard for data compression.
V.54	A CCITT standard for local and remote diagnostic loopback tests.
