Glossary

server	A device that offers a specific service, such as database management, to a client.
SES	Severely Errored Seconds. Usually defined as a second during which a specific number of
	CRC errors was exceeded, or an OOF or other critical error occurred.
Set Command	A command providing write access to SNMP MIB objects.
(SNMP)
SF	Superframe. Also known as D4 framing, the T1 transmission standard that specifies
	12 frames to be used for frame synchronization and to locate signaling bits.
SLIP	Serial Line Internet Protocol. Protocol for serial operation on an internet.
SNMP	Simple Network Management Protocol. Protocol for open networking management.
Stat branch	Status branch of the DSU/CSU menu tree.
StEvnt	Status Event Register. Records the occurrence of certain alarm conditions.
subnet	A portion of a network, which may be a physically independent network segment, that
	shares a network address with other portions of the network and is distinguished by a
	subnet number. A subnet is to a network what a network is to an internet.
subnet mask	A number that identifies the subnet portion of a network address. The subnet mask is a
	32-bit Internet address written in dotted-decimal notation with all the 1s in the network and
	subnet portions of the address.

synchronous data T1

TCP/IP

Data transmission that is synchronized by timing signals. Characters are sent at a fixed rate.

A term for a digital carrier facility used to transmit a DS1 formatted digital signal at 1.544 Mbps. It is used primarily in North America.

Transmission Control Protocol/Internet Protocol. The dominant protocol suite in the worldwide Internet, TCP allows a process on one machine to send data to a process on another machine using the IP. TCP can be used as a full-duplex or one-way simplex connection.

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 a normal terminal user of the
	remote host.
time slot	One of the ways in which bandwidth can be specified for multiplexer channel groups. Time
	slots are specified by any number from one to twenty-four, with each time slot equal to
	64 kbps.
trap (SNMP)	A notification message to the SNMP manager when an unusual event occurs on a network
	device, such as a reinitialization.
TStat branch	Test Status branch of the DSU/CSU menu tree.
TX	Transmit. To send signals from a device.
TXC	Transmit Clock. V.24 circuit 114.
TXD	Transmit Data. Pin 2 of the EIA-232 interface that is used by the DTE to transmit data to the
	modem. Conversely, the modem uses Pin 2 to receive data from the DTE.
UAS	Unavailable Seconds. A count of one-second intervals when service is unavailable.
UDP	User Datagram Protocol. A TCP/IP protocol describing how messages reach application
	programs within a destination computer.
UL	Underwriter’s Laboratories, Inc. An organization which promotes product safety.
V.24	An ITU-T standard for a low-speed, 25-position, DCE/DTE interface.
