Protection Switch
The ARG FLEX 2400 is a fully managed, high availability protection switch and distribution amplifier with different interfaces including SDI, ASI, Telecom E3, DS3, RF (L-Band), STM-1 and Gigabit Ethernet.
The ARG FLEX 2400 can be programmed to switch on loss of signal and pre-determined signal deterioration such as bit error rate, frame loss or loss of synchronization and a manual switchover is possible via a front panel key, or forced by GPIs on the rear panel.
