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. 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.
Australia Warning
This equipment will not operate when mains power fails.
Restriction of Hazardous Substances (RoHS)
All Polycom products comply with the requirements of the EU Directive Restriction of Hazardous Substances
(RoHS) 2002/95/EC. Statements of compliance can be obtained from TypeApproval@polycom.com.
