DESCRIPTION
The SLIC KIT (L3000N/L3092) is a set of solid
state devices designed to integrate many of the
functions needed to interface a telephone line. It
consists of 2 integrated devices ; the L3000Nline
interface circuit and the L3092 control unit.
The kit implements the main features of the
BORSHT functions:
- Batteryfeed (balancemode)
- Ringing Injection
- SignallingDetection
- HybridFunction
The SLIC KIT injects the ringing signal in bal-
anced mode and requires a positive supply volt-
age of typically + 72V to be availableon the sub-
scriber card.
The L3000N/L3092 kit generates the ringing sig-
nal internally, avoiding the requirement for expen-
siveexternal circuitry. A low level 1.5Vrms input is
required. (This can be provided by the combo).
A special operating mode limits the SLIC KIT
power dissipation to 50mW in on-hook condition
keepingthe on/off hookdetectioncircuit active.
Through the Digital Interface it is also possibleto
set an operatingmode that allows measurements
of loop resistanceand thereforeof line lenght.
This kit is fabricated using a 140V Bipolar tech-
nology for L3000N and a 12V Bipolar I
2
L technol-
ogy for L3092.
Both devices are available PTH application
(FLEXIWATT15 and DIP28) or SMD application
(PowerSO-20 andPLCC28).
This kit is specially suitable to Private Automatic
Branch Exchange (PABX) and Low Range C.O.
Applications.
This isadvanced information on anew product now in development or undergoing evaluation. Details are subject to change without notice.
