Key Term Definitions
Acoustic Clarity Technology:
This Polycom patented technology allows you to enjoy instantaneous natural conversation. When paired with a full duplex speakerphone, echo is eliminated and both callers are able to speak simultaneously without experiencing voice dropouts. The voice clarity on conference systems that feature this technology is incredibly crisp and clear.
Full Duplex Operation:
The full duplex feature allows simultaneous flow of audio signals between your conferencing phone and that of the outside caller. Polycom systems carry a full duplex speakerphone, which can transmit and receive audio signals at the same time, in both directions.
When broken down into 2 parts, SIP and VoIP are acronyms for Session Initiation Protocol and Voice Over Internet Protocol. The SIP and VoIP features move voice traffic through IP networks instead of traditional circuit-switched networks. The most popular form of IP network is the internet, users can communicate online with applications such as Skype. SIP and VoIP have taken communication to a new level, allowing for innovative technologies to replace traditional, outdated methods. These protocols can be found in the Polycom SoundStation IP series.
Automatic Gain Control:
This adaptive technology is a standard feature in most electronic devices. Automatic Gain Control (AGC) takes the average output signal level and adjusts the gain to the appropriate level for input signal levels. For example, when a signal is too strong the AGC reduces its volume and when the signal is too weak the AGC increases the volume. In telephones the AGC is most commonly used when a conversation is recorded. The AGC will take the large signal from the local user and the small signal from the long distance user and produce a recording that is well balanced.
HD Voice Clarity:
High definition voice technology provides the user with crystal clear voice delivery and reception. Enjoy an improvement in overall audio experience during VoIP based communication. This wideband technology differs from standard telephony in that it doubles the sampling of sound stream and width of the sound spectrum. Think of the television industry and the difference between HD and non HD pictures. High definition in voice communication functions in the same way, the sound is simply clearer. When utilizing HD voice in VoIP applications you will experience minimal interference and background static.
With this technology you are able to enjoy echo free communication. With the cancellation and suppression processes, information is only sent across the line when someone is actually speaking. So when a person stops talking the signal is cut off, leaving no room for background noise to filter in and create an echo.
