Glossary

GSM defines two major categories of
logical channels:

TCHs Traffic CHannels, for speech or
user data

CCHs Control CHannels, for control
signalling.

-> Physical Channel -> Channel
Combination

Logical RU

A unit which can be referred to, but is not
a single physical unit. There are three
different kinds of logical RUs:

1. Buses

2. Antennas

3. Environment

LOS

Loss Of Signal

LVF

Low Voltage Filter

MADT

Mean accumulated downtime

Main RU

A main replaceable unit is a replaceable
unit that contains one or more processors,
to which software can be downloaded
from the BSC.

MHS

Modification Handling System

Ericsson trouble report database

MMI

Man-Machine Interface

Managed Object

MRT

Mean repair time

Mobile Station

MTBF

Mean Time Between Failure

MTBCF

Mean Time Between Catastrophe Failure

NCS

National Colour System

NMS

Nominal Power

The nominal power is the power level
defined when configuring the transceiver.
