Introduction
The Number Assignment Module (NAM) is
a section of memory that retains informa-
tion about the phoneÕs characteristics, such
as the assigned telephone number, system
identification number, and options informa-
tion.
Two methods are available to program the
NAM using the keypad: Test Mode and
User Mode.
Regardless of the method used, the NAM
must be programmed before the phone can
be placed into service. This chapter covers
the NAM Programming steps for Easy
NAM Programming which is the preferred
programming method
User Mode Programming
User Mode NAM programming requires a
special key sequence to enter, but can be
accomplished through the telephone keypad
without the use of any specialized hard-
ware.
The telephone number can be changed up to
fifteen times, after which the phone must be
reset in Manual Test Mode using the 32#
command (erasing all repertory memory
and initializing counters).
Some models may be available with a ÒUser
Mode NAM Programming ManualÓ which
describes the entry key sequences and the
programming steps for User Mode NAM
programming.
User Mode NAM programming steps are
different from Test Mode NAM program-
ming steps, and do not include all of the
option bits available in Test Mode NAM
programming.
Access to User Mode NAM programming
can be disabled by Test Mode NAM
programming step 11, bit C7. Detailed
description on Test Mode NAM Program-
ming can be found in the TDMA ST7797
Level 2 and Level 3 Service Manual.
The following page describes the step by
step procedure for Easy NAM Program-
ming, which is the preferred programming
method.
