Description
The VoiceEdge™ family VE750 series of Line Card
Access Switches (LCAS), which includes the Le75181,
Le75282 and Le75183 devices, is a family of
monolithic solid-state switches that is designed to
provide both power ringing access and test access on
the analog line card. These devices, while not a pin-
for-pin
replacement
for
the
traditional
electromechanical relay (EMR) solution, provide the
equivalent switching functionality. The VE750 series of
LCAS is meant as a solid-state alternative to the
EMRs.
The Le75183A/B/C devices are pin-for-pin compatible
with Zarlink’s L7583A/B/C devices.
Zarlink also offers a range of compatible SLIC devices
and codec/filters that can be used with the VE750
series LCAS for complete line card solutions that can
be used worldwide in analog line card applications.
