Product Emission Class

The Sonus SBC 1000/2000 system is a Class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

Emission Class Levels

Various national agencies (in the United States, the Federal Communications Commission (FCC)) govern the levels of electromagnetic emissions from digital devices. Electromagnetic emissions can interfere with radio and television transmission. To reduce the risk of harmful interference these agencies have established requirements for manufacturers of digital devices.

The manufacturer of a digital device must test and label a product to inform an end-user of the maximum emission level from the product when used in accordance with its instructions. The emissions levels encountered are classified as Class A or Class B. A system that meets the Class A requirements can be marketed for use in an industrial or commercial area. A system that meets the more stringent Class B requirement can be marketed for use in a residential area in addition to an industrial or a commercial area.

The end user is generally held responsible for ensuring that the system is suitable for its environment as stated in the above paragraph, and bears the financial responsibility for correcting any harmful interference.


Modifications or changes made to this device, and not approved by Sonus Networks, may void the authority granted by the FCC, or other such agency, to operate this equipment.
