Support Manual

This equipment shall not be used in any manner which could constitute a nuisance
to other customers.
The setting and features discussed below influence how your modem reacts with
the telephone network. If changes from the default values are made, then it is
possible that unwanted signals or interference may be generated; your modem
might dial wrong numbers or suffer from a reduced level of performance. We
strongly recommend that the settings are not changed under any circumstances
or the Permit/Telepermit may become invalid.
Initialization
Many communications programs react to the default settings when started.
This is usually achieved by the ATZ command and initializes your modem
for correct operation. Many programs are developed for worldwide use and
generally use the ATZ command; however, some programs have built-in modem
configuration utilities and these should not be used unless you can confirm that
they are compatible with Australian and New Zealand requirements.
If your program does not use the ATZ command to initialize, but instead sends a
complex string of characters, then it must be configured to send the correct string
for Australia and New Zealand. The correct initialization string is (spaces should
not be entered; they are to make it easier to read):
AT &F T /N6 S6=3 S7=45 % L=7 &Y0 &W0
Once you have entered this command string, it is written to the internal memory of
the modem and the default configuration.
Dialing
The modem supports both pulse and tone dialing in Australia and only tone
dialing in New Zealand. New Zealand users please note that if pulse dialing is
selected, then wrong numbers will be dialed, as the reverse numbering scheme is
not supported. There are several dial string modifiers referred to in the main users’
manual, and we suggest that they be used with caution to avoid problems when
making calls.
Automatic Answering
To conform with Austel and Telecom New Zealand requirements when
configuring your modem for auto-answering, please do not set the SO register to
values less than 2 or greater than 10 (Note: ATSO-O will disable auto-answering).
Pre-configured software should be checked and changed as necessary. These
settings ensure:

A person calling your modem will hear a short burst of ringing before the
modem answers. This confirms that the call has been successfully switched
through the network.

Caller identification information (which occurs between the first and second ring
cadences) is not destroyed.
