Receive Slip Occurrence Indicator. One-clock-wide pulse for every slip of the
receive elastic store. Hardware version of SR1.4.
Receive CRC Error Indicator. One-clock-wide pulse for every multiframe that
contains a CRC error. Output forced to 0 during loss of sync.
Loss Of Transmit Clock Indicator. Real-time hardware version SR2.2
RFSYNC. Recovered frame-sync pulse.
PRBS Bit Error. A half-clock-wide pulse for every bit error in the received PRBS
pattern.
TDATA/RDATA
OUTB outputs an NRZ version of the transmit data stream (TDATA) prior to the
transmit line interface.
OUTA outputs the received serial data stream (RDATA) prior to the elastic store.
Receive CRC4 Multiframe Sync. Recovered CRC4 MF sync pulse.
Receive CAS Multiframe Sync. Recovered CAS MF sync pulse.
Transmit Current Limit. Real-time indicator that the TTIP and TRING outputs
have reached their 50mA current limit.
TPOS/TNEG Output. This mode outputs the AMI/HDB3 encoded transmit data.
OUTA outputs TNEG data.
OUTB outputs TPOS data.
