The 7780BPX-DS3 provides automatic changeover functionality for bypass protection of DS3 and E3 signals. Main and Standby inputs are provided, each with individual signal power measurement. If the power level of the Main input drops below the user-adjustable threshold, changeover to the Backup input will occur automatically. The switch may be configured to remain on the Backup input until the user sets the switch back to the Primary input, or the switch may be configured to automatically switch back to the Primary input once it has been detected that the signal has been restored. The switch may also be configured for manual switching operation, or switching via GPI or SNMP command. The 7780BPX-DS3 is VistaLINK® enabled for monitoring and control over SNMP. A card edge menu system is also provided for full local monitoring and control. This high-density product occupies only 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.
