DESCRIPTION
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
components.
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).

Ringing Mode. Sets bias conditions during ringing. Must be set
to logic 1 during ringing. Must be set to logic 0 within 500ms of
Ring Trip detect and during normal Off Hook condition.
Audio Out. This is the analog output signal (from Tip and Ring)
to the Codec. Must be ac coupled with typically 100nF.
Balance Impedance. Connect programming components
between ZB and VIN on Ag1460P only.*
Analog Supply. Each pin must be connected to +5VPWR with
10Ω resistors. Decouple each with 100uF (16V) capacitors.
Switch Hook. Indicates Off-Hook when at logic 1. Must be
de-bounced
Terminal Impedance 1. Connect programming components
between ZT1 and ZT2 on Ag1460P only.*
Terminal Impedance 2. Connect programming components
between ZT1 and ZT2 on Ag1460P only.*
Audio In. This is the analog input signal from the Codec (which is
output on Tip and Ring). Must be ac coupled with typically
100nF.
Forward/Reverse. A logic 0 will reverse the Tip and Ring voltage
polarities. F/R is toggled to produce the ringing output.
Slew Rate Capacitor. A capacitor is fitted between this pin and
GND to control the battery reversal and the ringing slew rate.
220nF is recommended.
Loop Off. A logic 1 removes the loop current from the line.
Connect to logic 0 for normal operation.
12, 17, 40, 45 TIP (A) Tip. Connects to the subscriber line Tip.
13, 16, 41, 44 RING (B) Ring. Connects to the subscriber line Ring.
DC-DC Supply. +5V input for the integral DC-DC converter.
14 +5VPWR Decouple to GNDPWR with 220uF (10V) low impedance
capacitor.
15 GNDPWR DC-DC Ground. Internal ground for the DC-DC converter.
42
PD
Power Down. A logic 1 powers off the DC-DC converter.
Connect to logic 0 for normal operation.
43 GNDA Analog Ground. Normally connected to system ground.
*On Ag1460 these pins are used for internal connection, and must be left unconnected.
