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: 3 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. 3 Caller identification information (which occurs between the first and second ring cadences) is not destroyed.
