DESCRIPTION
The LH1529A and LH1529B telecom switches consist of an
optically coupled solid state relay (SSR) and bidirectional
input optocoupler. The SSR is ideal for performing switch
hook and dial-pulse switching whilst optocoupler performs
ring detection and loop current sensing functions. Both the
SSR and optocoupler have an isolation test voltage of
5300 VRMS.
