Automatic Multiple Dialing Attempts

Most communication software can be configured to make automatic dialing attempts to a telephone number that is busy or not answering (automatic redial function). The maximum number of all attempts that can be made in one sequence must not exceed the numbers shown in the following table. If your program makes continuous automatic dialing attempts or more than the number in the table, and it cannot be changed, an alternative program must be used or automatic dialing disabled. There is no limit for manually initiated dialing attempts.

	Number of	Pauses between	Pauses between
	attempts per	attempts	sequences
Country/region	sequence	(seconds)	(minutes)

Australia	10	3	30
New Zealand	10	60	60

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.
