WSR-88D DCU BITE Packets

RCP8 generates this BITE packet when the WSR-88D DCU pedestal interface has been enabled. The identification byte is selectable to avoid conflicts with other BITE packets. The S number after each table entry is the numbered status variable that is driven by the respective bit. Most bits in the BITE packet are copies of their DCU counterparts (with their original word and bit numbers shown in parenthesis). However, S110 ... S119 are supplied by RCP8.
