US Patent 11917260 Transparent clock functionality in regenerative taps

Within a regeneration device, regenerate a first input signal having a first timestamp and an inadequate signal-to-noise ratio and bypass a second input signal having a second timestamp and having an adequate signal-to-noise ratio. With a central processing server coupled to the device, obtain, from a delay tracking database, a first delay associated with a first signal path for the first input signal and a second delay associated with a second signal path for the second input signal. With the server, cause to be sent downstream the regenerated first input signal together with the first timestamp and the first delay, and the non-regenerated second input signal together with the second timestamp and the second delay.
