DESCRIPTION
• Silver Telecom “design-in” assistance.
The Silver Telecom Ag1160 comprises a
single Subscriber Line Interface Circuit (SLIC)
in a 21 pin dual in line (DIL) 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.
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 Ag1160 has been designed to work with
loop lengths of up to 3.0km (800R including
telephone). Its performance to regulatory
standards allows use in public and private
network applications.
The Ag1160 has integral dc/dc converter and
ringing generation thus providing all the line
The Ag1160 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).

Data Sheet
Codecs require information about the transfer
characteristics of the SLIC with which they are working.
Some codecs require a .CIR netlist. A .CIR netlist can
be obtained by contacting either Silver Telecom or your
local representative, to allow certain Codec
programming coefficients to be generated.
If a simple (non-programmable) Codec is being used
contact Silver Telecom for an Ag1160 version with an
alternative impedance.
2.3 Network Balance Impedance.
The network balance impedance, Zb, of the SLIC is set
to 600R for the standard Ag1160. For countries where
the network balance impedance is 600R e.g. North
America, no external adjustment is required. For
countries where an alternative network balance
impedance is used the Codec filter characteristics can
be programmed to give the required matching. The
.CIR netlist may be needed to allow the Codec
programming coefficients to be generated.

5V RINGING SLIC
If a simple (non-programmable) Codec is being used
contact Silver Telecom for an Ag1160 version with an
alternative impedance.
2.4 Tip & Ring Polarity Reversal.
The Ag1160 can reverse the battery voltage polarity at
Tip and Ring via the F/R pin.
If F/R is held at logic 1 (forward) the d.c. voltage at Tip
is positive with respect to Ring. If F/R is taken to logic
0 the voltage polarity is reversed. The F/R pin should
not be left floating, and if not used should be tied high
as shown in Figure 4.
2.5 On Hook Transmission.
The Ag1160 is capable of on-hook transmission. This
means analog signals can be transmitted from VIN
through Tip and Ring and onto the line even when no
loop current is flowing. This can be used when

The phone goes off hook, and SHK is detected at point A
(leading edge). RM must be switched low in <500ms
(point B), and the ringing cadence should be removed
from F/R..
As long as the telephone is off hook, SHK will remain high.
