4.1 Operation Modes
DS-1010 has four Operation Modes with Mode 0 being the default Operation Mode:
Mode 0: Normal Active Bypass
If DS-1010 receives heartbeat signals within the TIMEOUT time period, the switching mode
remains or is changed to Active Switching Mode. If DS-1010 does not receive heartbeat signals
within the TIMEOUT time period, it will change to or remain in Bypass Switching Mode. By default
(without any heartbeat), DS-1010 will remain in Bypass Switching mode.
Mode 1: Normal Active Inline
If DS-1010 receives heartbeat signals within the TIMEOUT time period, the switching mode
remains or is changed to Bypass Switching Mode. If DS-1010 does not receive heartbeat signals
within the TIMEOUT time period, it will change to or remain in Active Switching Mode. By default
(without any heartbeat), DS-1010 will remain in Active Switching mode.
Mode 2: Manual Active Inline
DS-1010 is always in Active Switching Mode.
Mode 4: Manual Active Bypass
DS-1010 is always in Bypass Switching Mode.
Mode 5: Manual Passive Bypass
DS-1010 is in passive bypass, where the optical switch is close in bypass mode.
