Bits 0 to 4: T1/E1 Drop Port A Select Bits (DPAS0 to DPAS4).
Bits 8 to 12: T1/E1 Drop Port B Select Bits (DPBS0 to DPBS4).
These bits select which of the 28 T1 ports or 16 E1 ports (if any) should be output at either Drop Port A or Drop
Port B. If no port is selected, the LRDATA, LRCLKA, LRDATB, and LRCLKB output pins will be forced low.
