• 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.
