idle code

In a T3 circuit, an idle code consists of a sequence of 1100 over the entire payload bandwidth.

in-band

Signaling (dialing, diagnostics, management, configuration, etc.) over the same channel used for data.

IP

internet protocol. A protocol which provides for transmitting blocks of data between hosts identified by fixed-length addresses.

LAN

local area network. A privately owned network that offers high-speed communi- cations channels to connect information processing equipment in a limited geo- graphic area.

local loopback (LL)

A type of test used to verify the operation of the local terminal equipment, the CSU, and the connection between the two. The signal from the DTE is looped back by the CSU and is sent back to the DTE.

loopback

The technique for testing the processing circuitry of a communications device. May be initiated locally or remotely via a telecommunications circuit. Device being tested will echo back received test data. The results are compared with the original data.

LOS

loss of signal. Defined as a line state in which no pulses are received for 175 bit positions.

M13

DS1/DS3 multiplexer that combines up to 28 DS1 channels into one DS3 chan- nel. Uses two-stage, bit synchronous TDM.

Mbps

Megabits per second (one million bits per second).
