Glossary

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.
self-test	A test that checks most hardware components when power is applied to the device or a
	reset is initiated.
SES	Severely Errored Seconds. For T1 data, seconds with 320 or more CRC6 errors or errored
	frame alignment signals.
SLIP	Serial Line Internet Protocol. A link layer protocol being used over serial lines by IP.
SNMP	Simple Network Management Protocol. A generic internet network management protocol
	that allows the device to be managed by any industry-standard SNMP manager.
subnet	An IP addressing standard in which a portion of the host address can be used to create
	multiple network addresses that are logically a subdivision of the network address.
subnet address	The subnet portion of an IP address. In a subnetted network, the host portion of an IP
	address is split into a subnet portion and a host portion using a subnet address mask. This
	allows a site to use a single IP network address for multiple physical networks.
subnet mask	An integer used with the IP address of the host to determine which bits in the host address
	are used in the subnet address.
synchronous	Data transmission that is synchronized by timing signals. Characters are sent at a fixed
	rate.
TCP/IP	Transmission Control Protocol/Internet Protocol. Refer to IP.
TDM	Time Division Multiplexer. A device that enables the simultaneous transmission of multiple
	independent data streams into a single high-speed data stream.
Telnet	Virtual terminal protocol in the Internet suite of protocols. Allows the user of one host
	computer to log into a remote host computer and interact as the user for that host.
time slot	The allocated DS0 channel slot when DS0 channels are combined to form an aggregate
	bit stream.
TM	Test Mode. An EIA-lead standard for V.24 circuit CT 142; an output signal (DCE-to-DTE).
trap (SNMP)	A notification message to the SNMP manager when an unusual event occurs on a network
	device, such as a reinitialization.
TX	Transmit. To send signals from a device.
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).
T1	A wideband digital interface operating at 1.544 Mbps.
UAS	Unavailable Seconds. A count of 1-second intervals when service is unavailable.
UDP	User Datagram Protocol. An Internet protocol.
