[Silver Telecom]

DESCRIPTION

The Silver Telecom Ag1110 comprises a single Subscriber Line Interface Circuit (SLIC) in a single-in-line (SIL) 13 pin format. The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost.

The SLIC is highly featured requiring a minimum of external components. Functions such as a relay driver, are provided on board along with precision loop feed resistors.

The Ag1110 has been designed to work in private systems where cost is a major concern and advanced public network signalling is not a requirement. The system interface has been designed for direct connection to popular codecs for both audio and signalling.

The Ag1110 is ideal for any application where high-density line interfacing is required, such as Computer Telephony Integration (CTI), Small Office Home Office (SOHO) and PABX.
