Bell Compatible Operation Bell compatible mode should not be used. Nearly all modems use CCITT mode because Bell mode is limited to a maximum speed of 300 or 1200 BPS, and some network interference problems may arise due to line signaling requirements. Parallel Telephones If you find that you regularly experience line noise or other interference when using your modem, we suggest disconnecting other telephones from the line. Some telephones may place a load across the telephone line when not in use, which adversely affects the performance of your modem. If disconnecting parallel telephones reduces the interference, then it may be necessary to have the telephone(s) repaired or replaced. Warning: (New Zealand users only) Please note that operation of this modem on the same line as telephones or other equipment with audible ringing devices, or automatic ringing detectors, may cause "bell tinkle" or false tripping of the ringing detector. If this occurs, do not contact Telecom Faults Service. Also, please note that the power consumed from the telephone line by this modem may not provide for the effective transfer of a call to or from other equipment connected to the same line. Connecting to Other Equipment There are two telephone line sockets in your modem, marked LINE and PHONE. The telephone line is connected to the LINE socket, and other equipment, such as the telephone, is connected to the PHONE socket. Please note that Austel permitted/NZ Telepermitted equipment only may be connected to the PHONE socket. Miscellaneous There are many commands referred to in the main user's manual. Incorrect use of some of these commands may render your modem inoperative or severely degrade its performance. Generally, it is best not to change any setting unless you are an experienced user. Should you accidentally alter any settings, and are unsure how to undo the changes, it is best to completely re-initialize your modem by giving the AT&F command (the only time you should use this command) and then manually enter the initialization string of point A. This will reset your modem to the correct settings for Australia and New Zealand. Voice Features If your new modem is fitted with voice features, then it is illegal in Australia and New Zealand to use it with software that allows recording of telephone conversations. (It can be used as an answering machine, mail box center, telemarketing system, and so forth, but it cannot be used to record a "live" conversation between telephone users.) If your software supports telephone conversation recording (perhaps called Two-way Recording), then this feature must be disabled in the program configuration.
