Russian Compliance – SoundStation IP 5000
Ministry of Information Technologies & Communication of the Russian Federation –
Declaration of Conformity. DoC # -5454. Expiry 26 September 2014.
New Zealand Telepermit
Polycom SoundStation IP 5000 Handsfree VoIP Conference System (PTC 220/10/039).
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 CODEC and Optimum Packet Size for transmission through the Public Switched Telephone Network (PSTN)
Because of the extensive delay already experienced when calling cellular and international networks,
Telecom Access Standards recommends the use of 20mS or less packet length when passing packets
through the PSTN. The use of G.711 codecs and 20mS or less packet length is critical to maintaining delay
times which comply with PTC220 requirements (<50mS).
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.
