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.
The Use of IP Networks through the PSTN
• 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
• 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 ≥ 64 ms
to be required.
Important Notice
• Under power failure conditions this appliance may not operate. Please ensure that a
separate telephone, not dependent on local power, is available for emergency use.
• No “111” or other calls can be made from this device during a mains power failure.
