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.

Dynamic Noise Reduction:
One of Polycom's signature features, Dynamic Noise Reduction (DNR) eliminates the unwanted background noise that plagues more traditional conferencing methods. This technology was first introduced in the 1980's and targeted noise reduction in long distance communications. DNR can cut down clatter by as much as 10 decibels and can be paired with similar systems. The Polycom systems that carry this feature provide the user with optimum microphone sensitivity while removing dynamic noise. DNR can really make a difference when conferencing with client's long distance, the level of professionalism will be much appreciated.

Analog is the original telephone technology, a system that converts air vibrations (like those created by the human voice) into similar electrical frequencies. Analog lines can support phones, fax machines, and modems and are typically found in homes or small office settings. Analog systems measure data in one continuous variable while digital breaks down and manipulates the data. One of the advantages of analog systems is that they dot not require a filter for band-limiting. Several SoundStation models operate on an analog system with features that are specifically designed for day to day communication.

Digital PBX:
A digital, private branch eXchange (PBX) system connects the internal telephones of a private business. The job of a PBX is to maintain and establish a link between two users, disconnect the users and meter the call. These systems are meant for use in the workplace, not at the level of public phone companies or service providers. Every telephone in the business is wired to the PBX system; this is why an access code is required to dial outside numbers. With a digital PBX system a business can drastically reduce the number of telephone lines they must lease from a national service provider.

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.
