Transceiver Labelling

Introduction
Each Motorola GSM transceiver will be
labelled with various number configura-
tions. The following information shows and
explains the common labelling titles.
Title Explanations
MSN
The Mechanical Serial Number (MSN) is an
individual number, uniquely identifying the
unit. The MSN will remain the same
throughout the units life, even if the main
board is replaced. Because the MSN is
unique to the unit, it is often used for
logging and tracking purposes by Motorola
National Service Centres on EPPRS. The
MSN is divided into the sections shown
below.
