ABSTRACT:
A method and switch appratus for transporting an ATM layer OAM cell across a FUNI are disclosed. The method broadly includes generating a DXI (FUNI) frame from the ATM layer OAM cell by using certain bits of the five byte ATM overhead as bits in the two byte DXI (FUNI) header, using the forty-eight byte ATM OAM cell payload as the payload for the DXI (FUNI) frame, and providing an indication in a predetermined bit field of the two byte DXI header that the forty-eight byte payload is an ATM OAM cell. Preferably, the predetermined bit field includes the previously reserved second lsb of Octet 1 of the DXI frame header, and the previously reserved third lsb of Octet 2 of the DXI frame header, which are set to values of "0" and "1" to indicate an ATM OAM cell, and to "0" and "0" to identify "regular" data.
