If configured to operate as an Input Port
If the Slow-Speed Interface is configured to operate as an Input Port,
then this port can be configured to accept a DS3, E3 or STS-1 signal
(from external circuitry) and it will ADD this DS3/E3/STS-1 signal into the
Selected Ingress Direction Channel within the XRT94L31. In this mode,
the SSI_CLK will function as a Clock Input signal that can accept either a
34.368MHz, 44.736MHz or 51.84MHz clock signal (depending upon
which type of signal is being ADDed.
If configured to operate as an Output Port:
If the Slow-Speed Interface is configured to operate as an Output Port,
then this port can be configured to output (or DROP out) the Selected
Ingress Direction Channel within the XRT94L31.In this mode, the
SSI_CLK will function as a Clock Output signal which will be at either the
34.368MHz, 44.736MHz or 51.84MHz clock frequency (depending upon
which type of signal is being DROPed)
