New Zealand Telepermit
Polycom SoundPoint IP321, 331, and 335 VoIP Telephone PTC 220/08/063
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.
The Use of Voice Compression through the PSTN
Because of the extensive delay already experienced when calling cellular and international networks, some of which
is already caused by their use of voice compression technologies. Telecom Access Standards will only approve G711
voice technology for use on the PSTN. G711 is an ‘Instantaneous Speech encoding Technique’ whereas G729 and
all its variants are considered ‘Near Instantaneous’ introducing additional delay into the speech signal.
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 to be required.
Modification of this Polycom SoundPoint IP321, 331, and 335 VoIP Telephone for the New Zealand Network
All samples of Polycom SoundPoint IP321, 331, and 335 VoIP Telephones connected to the Telecom network shall
be equipped with the following software batch Rev 3.0.2.0917. Equipped with this software batch the IP telephone is
known to comply with the New Zealand speech transmission plan.
