DESCRIPTION
The Ag1460 has integral dc/dc converter and
ringing generation thus providing all the line
powering requirements from a single supply.
The SLIC requires a minimum of external
components.
The Silver Telecom Ag1460 series comprises
four
individual
single
Subscriber
Line
Interface Circuits (SLICs) in a 72-pin SIMM or
56 pin DIL format.
The combination of
features and packaging offers extremely
efficient use of board area, saving significant
system size and cost, maximising time to
market for Telephony Systems developers.
The system interface has been designed for
connection to all popular codecs of both the
audio and signalling connections.
The Ag1460 has been designed to work with
loop lengths of up to 3.0km (800
Ω including
telephone), with both resistive and complex
line
impedances.
Its
performance
to
regulatory standards allows use in public and
private network applications.
The Ag1460 is ideal for low line count, short
loop length applications, such as ISDN
Terminal Adaptors, Internet Telephony (VoIP),
Computer Telephony Integration (CTI), Digital
Loop Carriers (DLC), Wireless Local Loops
(WLL) and Small Office Home Office (SOHO).
