Line Card Access Switch
Overview
The Le75181A VoiceEdge Line Card Access Switch(LCAS), is a monolithic solid-state switch that is designed to provide both power ringing access and test access on the analog line card. This device, while not a pin-for-pin replacement for the traditional electromechanical relay (EMR) solution, provides equivalent switching functionality. The VE750 series of LCAS is meant as a solid-state alternative to the EMRs. |
