Description

The ringing FlexiSLIC™ PBL 387 73/1 Subscriber Line

Interface Circuit (SLIC) is a 90 V bipolar integrated cir-

cuit for use in short loop applications. The PBL 387 73/1

SLIC has been optimized for low power consumption,

low total line interface cost and for a high degree of

ﬂexibility in various applications.

The PBL 387 73/1 SLIC supplies a balanced, sinewave

or trapezoidal ringing signal of up to 81 V_Peak(85 V

DC supply) to the subscriber line across a load of up

to 5REN. The PBL 387 73/1 supplies programmable

constant current to the subscriber loop, sourced from

the talk battery. The On-Hook line voltage of 43 V to

56 V is derived from the battery. All battery switching

is internal to the device and is automatic. To further

reduce power consumption the automatic gain control

for the ring signal (AGC-R) keeps the level always

adjusted to the maximum, that can be sourced from the

available battery.

The SLIC incorporates loop current and ring-trip

detection functions. The PBL 387 73/1 is compatible

with loop start and ground start signalling. Two-

to four-wire and four- to two-wire voice frequency

(vf) signal conversion is accomplished by the SLIC in

conjunction with a standard codec. The line terminat-

ing impedance and balance impedance is program-

mable and may be complex or real for worldwide

compliance.

Longitudinal balance speciﬁcations and other device

characteristics are in compliance with Telcordia (Bell-

core) and ITU-T requirements.

Tip and ring voltages are UL-1950 compliant;

i.e. no two-wire line voltage exceeds 56 V. The

PBL 387 73/1 SLIC is packaged in a surface mount

28-pin SOIC package.
