A standard for modems operating full-duplex with asynchronous or synchronous data
over leased lines or dial networks at 4800 or 9600 bps.
A 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.
CCITT standard for error control protocol.
CCITT standard for data compression.
CCITT standard for local and remote diagnostic loopback tests.
A path for electrical transmission between two or more points. Also called a circuit, line,
link, path, or facility.
A letter, figure, number, punctuation, or other symbol.
A way to check the accuracy of data transmission by sending to the monitor (displaying)
all the characters being transmitted.
A screw lock tab installed over a circuit card's latch release tab to prevent the unit from
being removed without a tool. It is used on SDUs, modems, and filler panels.
One of two modem operating modes. When in Command mode, the modem accepts
commands instead of transmitting or receiving data.
A combination of a compressor at one point in a communication path for reducing the
volume range of signals, followed by an expandor at another point for restoring the
original volume range. Usually its purpose is to improve the ratio of the signal to the
interference in the path between the compressor and expandor.
One of five areas within the Configure branch containing modem settings. Configuration
areas include Active (Operating), Active (Saved), Customer 1, Customer 2, and Factory.
Modem software that sets specific operating parameters for the modem. Sometimes
referred to as straps.
An outlet on equipment and cables that provides a connection.
The modem transmits a carrier signal constantly, regardless of RTS.
The diagnostic interface between a network management system and a network device.
A control modem polls downstream tributary modems across the analog channel.
The modem's transmitter turns on and off in response to RTS. This mode is used by
multipoint tributary modems.
A user-defined configuration area containing customized configuration options for a
specific application.
