Perf branch Performance Report Branch of the CSU menu tree.
Payload Loopback. Loopback mode that loops the information received on the T1 network
PLB
interface back to the network after it has passed through receive and transmit framing
section.
An access point for data entry or exit.
port
POWER connector The power input connector on the CSU.
power-on self-test A test that checks most hardware components when power is applied to the device or a
reset is initiated.
PPP Point-to-Point Protocol. A protocol for packet transmission over serial links, specified by
Internet RFC 1661.
Performance Report Messages. Messages indicating the current state of a T1 line as
PRM
specified by ANSI-T1-403.
A set of rules that determines the behavior of devices in achieving and maintaining
protocol
communication.
Public Switched Telephone Network. A network shared among many users who can use
PSTN
telephones to establish connections between two points. Also known as dial network.
Test Patterns branch of the CSU menu tree.
Ptrns branch
A measure of the number of ones (marks, pulses) in relation to the total number of bits
pulse density
transmitted.
Quasi-Random Signal Source. A test pattern simulating a random pattern of digital ones
QRSS
and zeros used to simulate normal transmission.
Random-Access Memory. Read/write memory that is volatile and loses its contents when
RAM
power is removed.
A part of the device's memory that holds stored values.
register
Release branch of the CSU menu tree.
Rel branch
reset An initialization of the device that occurs at power-up or in response to a reset command.
RFC Request for Comments. One of the documents published by the Internet Engineering Task
Force that describe Internet protocols and policies.
RIP Routing Information Protocol. A protocol for exchanging routing information.
RJ48C An 8-position modular connector.
Repeater LoopBack. Loops the signal being sent to the network back to the DTE
RLB
Drop/Insert and data ports after it has passed through the framing circuitry of the device.
Rlpbk branch Remote Loopback Branch on the CSU menu tree.
A device that connects LANs by dynamically routing data according to destination and
router
available routes.
An Electronic Industries Association's standard for a low-speed, 25-position, DCE/DTE
RS-232
interface.
RS-232-like MIB 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.
RTS Request to Send. A signal from the DTE to the device, indicating that the DTE has data to
send. V.24 circuit 105.
