The Intelligent Telecom Automatic Protection Switches (APS) series are capable of making a clean switch between two inputs maintaining continuity synchronization for signals of T1 or E1 lines. It will prevent momentary malfunction of downstream equipment when cutting between two sources . Network operators will be able to increase the system MTBF and Quality of Service to their customers.

     Redundancy switching will be initiated automatically upon detection of any Loss of Signal, Loss of Frame, BER and AIS event registration. Based on relay architecture type of switching, the unit allows a loop thru function in case of a total system collapse, thus eliminating single point of failure conditions.
