New Zealand Telepermit
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.
