RL1
RIR2.7
Receive Level Bit 1. See Table 5-1.
RL0
RIR2.6
Receive Level Bit 0. See Table 5-1.
TESF
RIR2.5
Transmit Elastic Store Full. Set when the transmit elastic
store buffer fills and a frame is deleted.
TESE
RIR2.4
Transmit Elastic Store Empty. Set when the transmit elastic
store buffer empties and a frame is repeated.
TSLIP
RIR2.3
Transmit Elastic Store Slip Occurrence. Set when the
transmit elastic store has either repeated or deleted a frame.
JALT
RIR2.2
Jitter Attenuator Limit Trip. Set when the jitter attenuator
FIFO reaches to within 4 bits of its limit; useful for debugging
jitter attenuation operation.
RPDV
RIR2.1
Receive Pulse Density Violation. Set when the receive data
stream does not meet the ANSI T1.403 requirements for pulse
density.
TPDV
RIR2.0
Transmit Pulse Density Violation. Set when the transmit data
stream does not meet the ANSI T1.403 requirements for pulse
density.
