DESCRIPTION
The LH1529FP and LH1529GP telecom switches consist of an optically coupled solid-state relay (SSR) and a bidirectional input optocoupler. The SSR is ideal for performing switch hook and dial-pulse switching while the optocoupler performs ring detection and loop current sensing functions. Both the SSR and optocoupler provide 3000 VRMS of input to output isolation.
