APPLICATIONS
General telecom switching
- On/off hook control
- Dial pulse
- Ring current detection
- Loop current sensing 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.
