Line Card Access Switch  
VE750 Series

HFC/FITL  
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/D devices are pin-for-pin compatible with  
Legerity’s L7583A/B/C/D devices.  
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.
