Description

ANIC is a chip set PSB4451 to interface analog voice signals to digital terminals such as DSL transceivers. Its technology and design make it especially suitable for the use throughout the world for applications such as
• DAML (Digital Added Main Line) interface between a central office and digital line transceivers,
• PBX trunks,
• Universal DLC (Digital Loop Carrier) systems.

The ANIC chip set PSB4451 is an ideal analog front end to convert digital information into analog signals and vice versa for communication via telephone lines.

Reliability in digital processing is much better than in analog communications. The new design of the ANIC chip set PSB4451 has transferred processing that was previously done on the analog side to the digital part. Digital filters ensure great precision and virtually no fluctuation.

The use of digital filter processing in combination with software algorithms ensures excellent transmission performance and adaptability. The ANIC chip set is programmable to adapt to different countries' requirements. Coefficient sets can be downloaded to the ANIC chip set PSB4451 to comply with specifications throughout the world.
