15.1. Scope
15 EEPROM LAYOUT (BASE UNIT)
The purpose of this section is to describe the layout of the EEPROM (IC9) for the TCD725 Base Unit.
The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of the
base e.g. crystal frequency adjustment at address 0000 and 0001, some are set by the user configuration e.g. ringer volume
at address 0210, and some are set during normal use of the phone e.g. meter pulse billing at address 1040..015F.

at address 0210, and some are set during normal use of the phone e.g. meter pulse billing at address 1040..015F.
15.2. Introduction
The base unit uses a 32k bit (4096 x 8) serial EEPROM (IC9) for storing volatile parameters. All parameters are set up before
the base leaves the factory. Some of these are vital for the operation of the hardware so a set of default parameters is
programmed before the actual hardware fine-tuning can be initiated. This document lists all default settings with a short
description.

description.
In the tables below values in a range that are similar are not repeated; i.e. Address 00 to 01 contains the value 00 simply means
that the value 00 is repeated in all addresses in the range. All values in this document are in hexadecimal notation.
