PTC General Warning
R
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.
The Use of IP Networks through the PSTN
R
Internet Protocol (IP) by its nature introduces delay into speech signals as each data packet is
formulated and addressed. Telecom Access Standards recommends that suppliers, designers and
installers using this technology for calls to or from the PSTN refer to ITU E Model requirements in the
design of their networks. The overall aim is to minimize delay, distortion and other transmission
impairments, particularly for those calls involving cellular and international networks, which already
suffer extensive delay.
Echo cancellation
R
Echo cancelers 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
³
64 ms to be required.
Important Notice
R
Under power failure conditions this appliance may not operate. Please ensure that a separate
