• R 900C Read number of errors in last backend optical PRBS readback
• W 9100 Start transmitting for PC optical PRBS test
• W 9104 Read VMEDATA sequences from PC optical PRBS
• R 910C Read number of errors in last PC optical PRBS readback
• W 9200 Read VMEDATA*10000 bits from optical PRBS from DCFEB
• W/R 9204 Select or read DCFEB fiber for test
• R 9208 Read number of error edges in last DCFEB optical PRBS test
• R 920C Read number of bit flips in last DCFEB optical PRBS test
• W/R 9300 Select or read PRBS type for all optical tests: 1 PRBS7 2 PRBS15 3 PRBS23 4 PRBS31
• W 9400 Initiate N*10000 bit copper OTMB PRBS test (RX to OTMB and TX from OTMB)
• R 9404 Read number of TX enable PRBS enables sent by OTMB
• R 9408 Read number of good 10000 bits sent by OTMB
• R 940C Read number of bit errors in last OTMB PRBS test
• W 9410 Reset OTMB PRBS error counter
