HP Compaq Presario,Presario 1700 Reference Manual page 166

Some parameters required for compliance with Telecom's Telepermit requirements
are dependent on the equipment (PC) associated with this device. The associated
equipment shall be set to operate within the following limits for compliance with
Telecom's Specifications:
1. There shall be no more than 10 call attempts to the same number within any 30
minute period for any single manual call initiation, and
2. The equipment shall go on-hook for a period of not less than 30 seconds
between the end of one attempt and the beginning of the next attempt.
Where automatic calls are made to different numbers, the equipment shall go on-
hook for a period of not less than 5 seconds between the end of one attempt and the
beginning of the attempt.
The equipment shall be set to ensure that calls are answered between 3 and 30
seconds of receipt of ringing (S0 set between 2 and 10). This ensures the following:
1. 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.
2. caller identification (which occurs between the first and second ring cadences)
is not destroyed.
This equipment does not fully meet Telecom's impedance requirements.
Performance limitations may occur when used in conjuction with some parts of the
network. Telecom will accept no responsibility should difficulties arise in such
circumstances.
This equipment should not be used under any circumstances which may constitute
a nuisance to other Telecom customers.
This equipment shall not be set to make automatic calls to the Telecom 111
Emergency Service.
