	    DESCRIPTION
		"
		    The S/UNI-JET supports both M23 and C-bit parity DS3 framing 
                formats. This format can be extended to support direct byte map-
                -ping or PLCP mapping of ATM cells.
                
                Adm ---- M23 Operation:
                    The C bits are passed through transparently in M23 framer only
                mode except for the C-bit Parity ID bit which toggles every M fra-
                -me.
                    In M23 ATM applications, the C bits other than the Parity ID 
                bit are forced to logic one.
                
                Plcp ---- C-bit Parity Operation:
                    The C-bit Parity ID bit is forced to logic one. 
                    The second C-bit in Msubframe 1 is set to logic one. The third 
                C-bit in M-subframe 1 provides a far-end alarm and control (FEAC) 
                signal. The FEAC channel is sourced by the XBOC block. The 3 C-bits
                in Msubframe 3 carry path parity information. The value of these 3 
                C-bits is the same as that of the P-bits. The 3 C-bits in Msubframe
                4 are the FEBE bits. The 3 C-bits in M-subframe 5 contain the 28.2 
                Kbit/s path maintenance datalink. The remaining C-bits are unused 
                and set to logic one.
