L9310 Line Interface and Line Access Circuit
Full-Feature SLIC, Ringing Relay, and Test Access Device
Introduction
The L9310 is a combination full-feature, ultralow-
power SLIC, solid-state ringing access relay, and line
test matrix. It is part of a pin-for-pin compatible family
of devices designed to serve a wide variety of appli-
cations. The L9310 is optimized for European
Access applications and North American access
where per-line testing and TA-909 longitudinal bal-
ance are required.

Description
The L9310 electronic line interface and line access
circuit (LILAC) provides all the functions that are nec-
essary to interface a codec to the tip and ring of a
subscriber loop, integrating the battery feed and ring-
ing access relay and line test access in one low-
power, low-cost package.
The L9310 requires a 5 V and battery supply to oper-
ate. Included is an automatic battery switch. The bat-
tery feed offers forward and reverse battery, on-hook
transmission, ground start, ground key, and meter
pulse operational modes. It also has a low-power
scan and a disconnect mode.
In all operating states, this IC is designed for minimal
power dissipation. This device is designed to mini-
mize the number of external components required at
all interfaces.
The dc template, current limit, and overhead voltage
and loop supervision threshold are programmable via
an applied voltage source. The voltage source may
be an external programmable voltage source or
derived from the V
REF
SLIC output.
The integrated solid-state switch offers power ringing
access. Impulse noise is minimized, thus eliminating
the need for external zero-cross switching circuitry.
The L9310 provides line test capability. The differen-
tial or single-ended ac and dc line voltage or current
may be measured by the L9310.
