Description
Applications
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-

LCAS is meant as a solid-state alternative to the
EMRs.
