New Zealand Telecom Warning Notice
1. The grant of a Telepermit for any item of terminal equipment indicates only that Telecom has accepted that
the item complies with minimum conditions for connection to its network. It indicates no endorsement of the
product by Telecom, nor does it provide any sort of warranty. Above all, it provides no assurance that any
item will work correctly in all respects with another item of Telepermitted equipment of a different make or
model, nor does it imply that any product is compatible with all of Telecom’s network services.
This equipment is not capable under all operating conditions of correct operation at the higher speed which it
is designated. 33.6 kbps and 56 kbps connections are likely to be restricted to lower bit rates when
connected to some PSTN implementations. Telecom will accept no responsibility should difficulties arise in
such circumstances.
2. Immediately disconnect this equipment should it become physically damaged, and arrange for its disposal or
repair.
3. This modem shall not be used in any manner, which could constitute a nuisance to other Telecom
customers.
4. This device is equipped with pulse dialing, while the Telecom standard is DTMF tone dialing. There is no
guarantee that Telecom lines will always continue to support pulse dialing.
Use of pulse dialing, when this equipment is connected to the same line as other equipment, may give rise
to ‘bell tinkle’ or noise and may also cause a false answer condition. Should such problems occur, the user
should not contact the Telecom Faults Service.
The preferred method of dialing is to use DTMF tones, as this is faster than pulse (decadic) dialing and is
readily available on almost all New Zealand telephone exchanges.
5. Warning Notice: No ‘111’ or other calls can be made from this device during a mains power failure.
6. This equipment may not provide for the effective hand-over of a call to another device connected to the
same line.
7. 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:
For repeat calls to the same number:
· 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
· 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.
For automatic calls to different numbers:
· The equipment shall be set to ensure that automatic calls to different numbers are spaced such
that there is no less than 5 seconds between the end of one call attempt and the beginning of
another.
· For automatically answered incoming calls:
· The equipment shall be set to ensure that calls are answered between 3 and 30 seconds of receipt
of ringing.
8. For correct operation, total of the RN’s of all devices connected to a single line at any time should not
exceed 5.
