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.
Echo Cancellation
Echo cancellers are not normally required in the Telecom PSTN because
gegraphic 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 or more to be required.
Compliance with New Zealand Law
The Ministry of Economic Development (MED) Radio Spectrum Management
(RSM) requires that Polycom Asia Pacific PTE limited have an approved
Supplier Declaration of Conformity (Sdoc) listing the EMC, the electrical safety

Note: Telecom Access Standards has not seen the EMC or the Radio Spectrum
test reports used by Polycom Asia Paciific limited to prove MED RSM
conformity.
