Data Sheet
surge resistor (25R typically). Alternatively a Teccor
F1250T or F0500T fuse may be used without a surge
resistor.
For ITU-T K20 power cross protection, a PTC
thermistor (eg. type JH330L) of 30R is suitable. The
lightning protection is provided by steering diodes
connected to 0V and upgrading D1 to a Tranzorb
device (Motorola or STM 1.5KE82A). For lightning and
power cross protection, D1 should be upgraded further
(General Semiconductor or Semitron 5KP75). Just one
Tranzorb is needed per linecard.
5.0 Approvals.
It can be seen from the Electrical Characteristics given
on subsequent pages that the SLIC has been designed
to meet the equipment standards of as many major
public telephone authorities as possible.
It is the responsibility of the equipment design authority
to ensure that their system meets the requirements of
the relevant regulatory bodies. Every effort is made to
ensure that Silver Telecom products are compliant with
the latest standards.

6.0 A Typical Application.
The Ag1160 has been designed to interface to any
Codec and is shown in a typical application in Figure 5.
The Codec which has been chosen to illustrate the use
of the Ag1160 is the Motorola MC14LC5480.
The status outputs from the SLIC are passed to the
micro-controller. These signals can then be processed
as necessary by the system software.
The audio signals which are on the 4 wire side of the
connection are coupled by 100nF capacitors to avoid
d.c. level problems between the two devices.
The Ag1160 provides for a 2 wire impedance and a
network balance impedance of 600
. For other
impedances a DSP codec can be used which can be
programmed using applications information available
from the codec manufacturer. The necessary transfer
function parameters for the Ag1160 are available from
Silver Telecom.
