L9310 Line Interface and Line Access Circuit

Full-Feature SLIC, Ringing Relay, and Test Access Device

Applications

Introduction

■ Pair Gain

The Agere Systems Inc. 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 applications. The L9310 is

optimized for European Access applications and

North American access where per-line testing and

GR-909 longitudinal balance are required.

■ Digital Loop Carrier (DLC)

■ Central Office (CO)

■ Fiber-in-the-Loop (FITL)

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.

Features

SLIC

■ 5 V and battery operation

■ Optional automatic battery switch

■ 15 operational and test modes

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.

■ Appropriate for 46 dB longitudinal balance applica-

tions

■ Minimal external components required at all inter-

faces

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.

■ Ultralow power dissipation

■ Software/hardware adjustable dc parameters and

supervision thresholds

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^REFSLIC output.

■ Meter pulse compatible

■ Ground start/ground key compatible

Solid-State Ring Relay

The integrated solid-state switch offers power ringing

access. Impulse noise is minimized, thus eliminating

the need for external zero-cross switching circuitry.

■ Low impulse noise

■ Current-limited switches/thermal protection

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.

Line Test Matrix

■ Single-ended or differential measurements

■ Current or voltage sense

■ ac or dc measurements

■ Dedicated analog input and output
