QUAD 5V RINGING SLIC
• Four highly featured SLICs in a 72 pin
SIMM or 56 pin DIL format.
• Integral DC-DC converter. No battery
voltage supply needed.
• Highly integrated with on board ringing
• Tip/Ring polarity reversal, On-Hook
Transmission for caller line ID.
• “Soft Shutdown” over current and
thermal protection provides fail-safe

• Simplified protection in “on-premise”
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.
• Silver Telecom “design-in” assistance.
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
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 (800Ω 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).
