Glossary

multiplexing	A method for interleaving several access channels onto a single circuit for transmission
	over the network.
node	A connection or switching point on the network.
non-latching	A non-latching loopback can only be initiated or terminated by the 56 kbps network service
loopback	provider.
NS	No Signal. A network-reported condition.
OOF	Out Of Frame. An error condition in which frame synchronization bits are in error. A
	network-reported condition.
OOS	Out of Service. A digital network trouble signal.
PAD	Packet Assembler/Disassembler.
point-to-point circuit	A data network circuit with one control and one tributary device.
protocol	The rules that govern how devices exchange information on a network. It covers 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.
reset	A reinitialization of the device that occurs at power-up or in response to a reset command.
RIP	Routing Information Protocol. Specifies the routing protocol used between DSUs.
RLSD	Receive Line Signal Detect. See CD.
router	A device that makes decisions about the paths network traffic should take and forwards
	that traffic to its destination. A router helps achieve interoperability and connectivity
	between different vendor's equipment, regardless of protocols used.
RS-232	An EIA standard for the 25-pin DCE/DTE interface. Same as EIA-232.
RTS	Request to Send. An EIA-lead standard for V.24 circuit CT 105; an input signal
	(DTE-to-DCE).
RXC	Received Clock. An EIA-lead standard for V.24 circuit CT 115; an output signal
	(DCE-to-DTE).
RXD	Received Data. An EIA-lead standard for V.24 circuit CT 104; an output signal
	(DCE-to-DTE).
SDLC	Synchronous Data Link Control. A standard data link protocol.
synchronous	Data transmission that is synchronized by timing signals. Characters are sent at a fixed
	rate.
TDM	Time Division Multiplexer. A device that enables the simultaneous transmission of multiple
	independent data streams into a single high-speed data stream.
TM	Test Mode. An EIA-lead standard for V.24 circuit CT 142; an output signal (DCE-to-DTE).
TXC	Transmit Clock. An EIA-lead standard for V.24 circuit CT 114; an output signal
	(DCE-to-DTE).
TXD	Transmit Data. An EIA-lead standard for V.24 circuit CT 103; an input signal
	(DTE-to-DCE).
V.35	ITU-T standard for a high-speed, 34-pin, DCE/DTE interface.
WAN	Wide Area Network. A network that operates over long distances and spans a relatively
	large geographic area (e.g., a country).
