1. Scope
The purpose of this document is to describe the layout of the EEPROM (IC103) for the Base Unit.
The EEPROM (IC103) contains hardware, software, and user specific parameters. Some parameters must be set during
production of the handset / base unit and some are set by the user when configuring the handset or during normal use of
the phone, e.g. re-dial stack.
production of the handset / base unit and some are set by the user when configuring the handset or during normal use of
the phone, e.g. re-dial stack.
EEPROM LAYOUT (BAE UNIT)
2. Introduction
Both the Handset and the Base Unit use a 32768 bit serial EEPROM (IC103) for storing volatile parameters. All hardware
specific parameters must be set up before the handset or base unit leave the factory. As some of these parameters are vital
for the operation of the hardware, a set of default parameters must be programmed before the actual hardware fine tuning
can be initiated. This document lists all default parameters with a short description. Those addresses that are included in
the base unit menu factory reset are checked in the ‘Menu reset’ column.

can be initiated. This document lists all default parameters with a short description. Those addresses that are included in
the base unit menu factory reset are checked in the ‘Menu reset’ column.
If a memory area contains the same value the notation “start-addr - end-addr value..value” is used. As an example refer to
handset EEPROM (IC103) address 02-0B. The value is designated as FF..FF meaning that all addresses in this area
contains the value FF.
handset EEPROM (IC103) address 02-0B. The value is designated as FF..FF meaning that all addresses in this area
contains the value FF.
Note that variables that are treated as words by the software are stored with least significant byte first in the EEPROM
(IC103). Example: to store 0x2A30 in Ring Det Low Cnt, 0x30 is stored in address 2E and 0x2A in address 2F.

In the layout table, adjustment parameters are marked with “(adj)”. Refer to 3.1.2 for a description of the adjustment param-
eters. Note that adjustment parameters are not allowed to be equal to 0xFF, if so they will be reprogrammed by the
default programming.
