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.

from your modem. Do not dial the area code digit or '0' prefix.
This equipment should not be used under any circumstances that may
constitute a nuisance to other Telecom customers.
