3162-A2-GB20-40
August 2000
A part of the device’s memory that holds stored values.
An initialization of the device that occurs at power-up or in response to a reset command.
Request for Comments. One of the documents published by the Internet Engineering Task
Force that describe Internet protocols and policies.
Routing Information Protocol. A protocol for exchanging routing information.
An 8-position modular connector.
Repeater LoopBack. Loops the signal being sent to the network back to the DTE
Drop/Insert and data ports after it has passed through the framing circuitry of the device.
A device that connects LANs by dynamically routing data according to destination and
available routes.
An Electronic Industries Association’s standard for a low-speed, 25-position, DCE/DTE
interface.
RFC 1659, which defines objects for managing RS-232-type interfaces (e.g., RS-422,
RS-423, etc.) and supports synchronous data ports and management communication
ports on the device.
Request to Send. A signal from the DTE to the device, indicating that the DTE has data to
send. V.24 circuit 105.
Receive. To obtain transmitted signals.
Receive Clock. V.24 circuit 115.
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.
Shared Diagnostic Control Panel. A feature that allows carrier-mounted devices to share
the same diagnostic control panel.
A test that checks most hardware components when power is applied to the device or a
reset is initiated.
A device that offers a specific service, such as database management, to a client.
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.
A command providing write access to SNMP MIB objects.
Serial Line Internet Protocol. Protocol for serial operation on an internet.
Simple Network Management Protocol. Protocol for open networking management.
Status Event Register. Records the occurrence of certain alarm conditions.
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.
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.
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.
