Paradyne 3910 Time Division, Multiplexer TDM, TMp, Top-Level menu, Training, Tributary modem

COMSPHERE 3900 Series Modems

Time Division	A device that enables the simultaneous transmission of multiple
Multiplexer (TDM)	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.
USOC	Universal Service Ordering Codes.
upstream modem	A device connected ªcloserº to the host computer.
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.
VF	Voice Frequency. The part of the audio frequency range used to
	transmit voice sound (usually 300 Hz to 3400 Hz). This band is
	used by the modem for its modulated signal.
XOFF	A character that tells the DTE or modem to stop transmitting data.
XON	A character that tells the DTE or modem to start or resume
	transmitting data.
