Compaq Armada 7400 Reference Manual page 173

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 speeds for which it is designed.
Telecom will accept no responsibility should difficulties arise in
such circumstances.
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.
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:
(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.
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.
