Description

The ringing FlexiSLIC™ PBL 387 71/1 Subscriber Line

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

cuit for use in short loop applications. The PBL 387 71/1

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 71/1 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 71/1 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, ground key and

ring-trip detection functions. The PBL 387 71/1 is

compatible with loop start and ground start signal-

ling. 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 terminating impedance and balance impedance

is programmable 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 71/1 SLIC is packaged in a surface mount

28-pin SOIC package.
