The Silvertel Ag1171 is a single Subscriber Line Interface Circuit (SLIC) in a 14 pin single
in line (SIL) format. The combination of features and packaging offers extremely efficient
use of board area, saving significant system size and cost, minimising time to market for
Telephony Systems developers.
The Ag1171 has been designed to work with loop lengths of typically 1.0km (470R
The Ag1171 has integral dc/dc converter and ringing generation thus providing all the line
powering requirements from a single supply. The Ag1171 requires a minimum of external
components, making it ideal for low line count, short loop length applications, such as WLL
Terminal (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and
Internet Telephony (VoIP).
