The IQASI82 monitors two ASI streams simultaneously for errors automatically switching from main and backup inputs depending on error criteria. Alarm management flexibility is provided by user defined criticality of alarms from TS Loss to PID monitoring and basic ETSI TR101290 alarms.
External GPI I/O, RS-232 and relay ports can also control functionality, allowing upstream triggering and or automated control via a third-party system.
IQASI82 can be used in conjunction with RollCall Network management system for advanced alarm monitoring and control.
Simultaneously monitors two MPEG-2 DVB ASI Transport Streams (TS)
Compliant with ETSI TR101290 specification and ATSC TS streams packet, burst and byte modes
Multiple switching methods, including near-seamless (between co-timed Identical streams) and non-seamless switching, manual or automatic
Transport stream monitoring and user selectable alarms, including:
Catastrophic failures such as no TS, loss of synchronization or low signal level
User-defined maximum and minimum data rates for each Transport Stream
Monitoring PIDs from a customer specified list up to a maximum of 64 (32 per input)
Alarm monitoring and logging via RollCall interface or SNMP
