DCC Receive Data 3:
Bit-serial D1-D3 or D4-D12 data from macro 3 of the SONET/SDH framer to
an external LAPD controller device. The data on this pin is output with the
R1DCLK3 clock.

DCC Receive Clock 1:
A bit clock from the SONET/SDH framer for clocking the data on the
R1DATA1 pin into an external LAPD controller or similar device. The clock
edge used for output of the R1DATA1 signal is selectable via a control bit.
DCC Receive Clock 2:
A bit clock from the SONET/SDH framer for clocking the data on the
R1DATA2 pin into an external LAPD controller or similar device. The clock
edge used for output of the R1DATA2 signal is selectable via a control bit.
DCC Receive Clock 3:
A bit clock from the SONET/SDH framer for clocking the data on the
R1DATA3 pin into an external LAPD controller or similar device. The clock
edge used for output of the R1DATA3 signal is selectable via a control bit.
DCC Receive Clock 4:
A bit clock from the SONET/SDH framer for clocking the data on the
R1DATA4 pin into an external LAPD controller or similar device. The clock
edge used for output of the R1DATA4 signal is selectable via a control bit.
