For Users in New Zealand
• This equipment shall not be set to make automatic
calls to the Telecom ‘111
’ Emergency Service.
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
minimise delay, distortion and other transmission
impairments, particularly for those calls involving
cellular and international networks, which already
suffer extensive delay.
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 ³ 64 mS to be
required.
