The 7702BPX-LB-B50 L band 2 x 1 protection switches provide automatic changeover functionality to provide bypass protection for RF signals from 950MHz to 2250MHz. The 7702BPX-LB-B50 occupy one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
Intelligent auto switching with input power detection
User definable threshold levels on 7703BPXA-LB version
Maintains switch state and RF channel on loss of power to card or frame
Supports automatic or manual control via GPI or SNMP on 7703BPXA-LB
Switch state indication via GPO
Card edge LEDs indicate active input channels, output channel and power levels below threshold
Fully hot swappable from front of frame
Wide operating frequency range, 950MHz - 2250MHz
Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK® capable on 7703BPXA-LB version
