Special Conditions for this User Guide
● PTC General Warning
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.
● Echo Cancellation
Echo cancellers are not normally required in the Telecom PSTN because geographic delays are
acceptable where CPE return loss is maintained within Telepermit limits. However, those private
networks making use of Voice over IP technology are required to provide echo cancellation for all
voice calls. The combined effect of audio / VoIP conversion delay and IP routing delay can cause the
echo cancellation time of 64 mS or more to be required.
