remote defect indication. An alert to a failure at the far end of
an ATM network. Unlike FERF (far-end remote failure), the
RDI alarm doesn't indicate the specific circuit with failure.

The duplication of hardware or software within a network to
endure fault-tolerant or back-up operation.
An algorithm that performs forward error correction (FEC) in
order to compensate for error bursts in data transmission.

A reference to how a user defines the external alarm condi-
tion (input) at their site, such as a temperature sensor, that
results in an action (output) such as a fan. When the STA-
TUS/CONTROL connectors on the Alarm module are con-
nected to an external device that is triggered remotely, a sig-
nal is sent, indicating a fault condition, which is displayed by
either Closed or Open on the Remote Input Status field.
A device that receives data on one communication link and
transmits it, bit by bit, on another link as fast as it is received
without buffering.
request for comment. Draft RFCs on particular topics are cir-
culated through the Internet community to gain feedback
from engineers and programmers on proposed TCP/IP stan-
dards about the Internet. The Internet Engineering Task Force
meets three times a year and either adopts what becomes a
standard RFC, or discards it.
The right button on a computer mouse. Clicking the right
mouse button on many computer screens brings up a menu
different from the drop-down options, or is more comfortable
for some users.
routing information protocol. A set of rules based on dis-
tance-vector algorithms that measure the shortest path
between points on a network. Each router maintains a rout-
ing table or database with this information and periodically
broadcasts it to neighboring routers.
registered jacks. An RJ-11 is a six-conductor modular jack
typically wired for four conductors, the most common tele-
phone jack in the world. The male connects a telephone,
modem, or fax machine to a female RJ-11 jack in the wall or
floor. The RJ-45 is an eight-pin connector used for transmit-
ting data from a data PBX, a modem, a printer, or a print
buffer over telephone wire.
