COMSPHERE 3900 Series Modems

NMS	Network Management System. A set of diagnostic and
	configuration management tools for a data communication
	network, consisting of software programs and dedicated computer
	hardware.
off-hook	A telephone or modem is being used.
on-hook	A telephone or modem is not being used.
Originate mode	The modem is in a state where it is ready to transmit a call. In a
	dial network, it is the modem that makes the call. In a leased-line
	network, it is one of two sides of the network that is selected to be
	the originating modem.
parity	A way of checking data accuracy by counting the number of bits
	that have a value of one.
PBX	Telephone switching equipment (Private Branch Exchange)
	dedicated to one customer. A PBX connects private telephones to
	each other and to the public dial network.
permissive interface	A dial modem operating mode characterized by a fixed output
	power level of ±9 dBm.
phase jitter	A rapid or repeated shifting of the relative phase of a signal
	resulting in unwanted distortion.
physical address	The diagnostic address of a control modem derived from its
	location in the carrier: its carrier and slot number.
point-to-point line	A line or circuit connecting two stations.
poll list	A list containing the network management addresses of
	downstream modems.
power-up self-test	A test that checks most hardware components when the modem is
	powered-on.
product code	A three-digit code indicating the modem's highest VF data rate.
protocol	The rules for timing, format, error control, and flow control during
	data transmission.
PSTN	Public Switched Telephone Network. A network shared among
	many users who can use telephones to establish connections
	between two points. Also known as dial network.
Quick Configuration	An informative display screen available from the modem's
display	Top-Level display. It provides such information as network
	position (control or tributary), network management address, DTE
	mode (Asynchronous or Synchronous), Line mode (Leased
	Answer, Leased Originate, or Dial), and the modulation scheme
	used by the modem.
