™ Le75181 A „ „ „ „ „ Voice Solution DESCRIPTION Central office DLC PBX DAML HFC/FITL Ringing Access Switch VE750 Series The VoiceEdge™ family VE750 series of Line Card Access Switches (LCAS) 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 pinfor-pin replacement for the traditional electromechanical relay (EMR) solution, provide the equivalent switching functionality. The VE750 series LCAS is meant as a solid-state alternative to the EMRs. The Le75181A/B device is pin-for-pin compatible with Legerity’s L7581A/B device, and the Le75181C device is pinfor-pin compatible with Legerity’s L8581A device. Legerity 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.
