RX Receive. To obtain transmitted signals.
RXC
Receive Clock. V.24 circuit 115.
RXD
Received Data. Pin 3 of the EIA-232 interface that is used by the DTE to receive data from
the modem. Conversely, the modem uses Pin 3 to transmit data to the DTE.
SDCP
Shared Diagnostic Control Panel. A feature that allows carrier-mounted devices to share the
same diagnostic control panel.
self-test A test that checks most hardware components when power is applied to the device or a
reset is initiated.
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 (SNMP) A command providing write access to SNMP MIB objects.
SLIP
Serial Line Internet Protocol. Protocol for serial operation on an internet.
SNMP
Simple Network Management Protocol. Protocol for open networking management.

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

device, such as a reinitialization.
TStat branch Test Status branch of the CSU menu tree.
T1 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.
TX
Transmit. To send signals from a device.
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.
