The 7702BPX-LB and 7703BPXA-LB L band 2 x 1 protection switches provide automatic changeover functionality to provide bypass protection for RF signals from 950MHz to 2250MHz.
7703BPXA-LB 已经内置了 VistaLINK® 技术，可通过 SNMP 进行远程控制和监测。这就提供给用户有能力在本地或远程配置和监测模块状态，如输入选择、能量水平和开关限值。
When used for automatic changeover, the 7702/7703BPXA-LB has a MAIN input and a STANDBY input. It will automatically switch to the Standby input when the Main input power is weak or lost. Switch back to the Main input when the signal is re-established, may be configured to happen manually or automatically. The 7702/7703BPX-LB may also be configured to operate manually as a 2:1 switch, which may be controlled locally or remotely via GPI or SNMP (7703 model only)
The 7702BPX-LB and 7703BPXA-LB 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.
