DESCRIPTION
The
subscriber
line
interface
kit
(L3000N/STLC3040) is a set of solid state de-
vices designed to integrate all the classical
BORSCHT functions (overvoltage protection ex-
ternal) and several additional features needed to
interface a telephone line.
The L3000N device is fabricated in B140II (140V
Bipolar) technology and is basically an analog
front end that drives the line via two output buffers
properly amplifying signal applied at its input by
the STLC3040. At the same time it provides back
to the STLC3040 an accurate image of the loop
current.
The STLC3040 device is fabricated in BiCMOS
(12V bipolar / 5V CMOS) technology. This device
interfaces the L3000N via a dedicated interface and
the C.O. backplane via a GCI compatible interface.
The STLC3040 processes the line current image
provided by the L3000N generating the transmit
signal and the proper voltage signal that will be
sent back to the L3000N in order to synthetize the
desired AC/DC impedances on the 2-wire side.
At the same time also the received signal on the
digital side is transferred into the line.
This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
