For the modem with approval number PTC 211/00/092:
v The grant of a Telepermit for a device in no way indicates Telecom
acceptance of responsibility for the correct operation of that device under
all operating conditions. In particular the higher speeds at which this
modem is capable of operating depend on a specific network
implementation which is only one of many ways of delivering high quality
voice telephony to customers. Failure to operate should not be reported as a
fault to Telecom.
v In addition to satisfactory line conditions a modem can only work properly
if:
– it is compatible with the modem at the other end of the call, and
– the application using the modem is compatible with the application at
the other end of the call - e.g. accessing the Internet requires suitable
software in addition to a modem.
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. a) 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 b) 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.
2. 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 next attempt.
3. The equipment shall be set to ensure that calls are answered between 3
and 30 seconds of receipt of ringing:
a. 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.
b. Caller identification information (which occurs between the first and
second ring cadences) is not destroyed.
4. The pulse dialing option is not compatible with the Telecom Network and
must not be used.
This equipment shall not be used in any circumstances which may constitute
a nuisance to other Telecom Customers.
