HXU-359 List 1

October 27, 2000

DDS

Digital Data Service

DS1

Digital Signal Level 1

DSU/CSU

Digital Service Unit / Channel Service Unit — Converts digital
data frames

DSX-1

Digital System Cross-connect frame

Errored Seconds

ESF

Extended Superframe

EXZ

Excessive Zeroes

FCLT

Facility Loopback

GND

Ground

HDB3

High Density Binary 3 — An E1 line code.

HDSL

High-bit-rate Digital Subscriber Line

HXU

HiGain Multiplexer Unit

LBO

Line Buildout — Software-configured LBO allows selection of
correct cable length for a particular location.

LINE

One or more SONET sections, including network elements at
each end, capable of accessing, generating, and processing
Line Overhead.

LOF

Loss of Frame — An LOF occurs when the OOF state exists for
a specified time in milliseconds.

LOP

Loss of Pointer — An LOP occurs when a specified number (8,
9, or 10) of consecutive invalid pointers or consecutive new
data flags are received.

LOS

Loss of Signal — An LOS is generated when the synchronous
signal level drops below the threshold at which a BER of 1 in
103 is predicted. It can occur due to a cut cable, excessive
attenuation of the signal, or equipment fault.

LSS

Loss of Sequence Synchronization

MDF

Main Distribution Frame

Multiplexer (MUX)

A device for combining several channels to be carried by one
line or fiber.

NDU

Network Doubler Unit
