Line Card Access Switch
VE750 Series
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/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.
