APPLICATION NOTE 388

Hitless Protection Switching with 1+1 Redundancy


Abstract: This application note discusses how to connect various Dallas Semiconductor T1/E1/J1 single-chip transceivers (SCTs) or line interface units (LIUs) for 1+1 redundancy. It contains a simple hardware design without relays and software register settings for specific devices. A designer can use these drawings to implement an operational system quickly.
