NAME AND DESCRIPTION
Receive Level Bit 1. See
Receive Level Bit 0. See
Transmit Elastic Store Full. Set when the transmit elastic
store buffer fills and a frame is deleted.
Transmit Elastic Store Empty. Set when the transmit elastic
store buffer empties and a frame is repeated.
Transmit Elastic Store Slip Occurrence. Set when the
transmit elastic store has either repeated or deleted a frame.
Jitter Attenuator Limit Trip. Set when the jitter attenuator
FIFO reaches to within 4 bits of its limit; useful for debugging
jitter attenuation operation.
Receive Pulse Density Violation. Set when the receive data
stream does not meet the ANSI T1.403 requirements for pulse
density.
Transmit Pulse Density Violation. Set when the transmit data
stream does not meet the ANSI T1.403 requirements for pulse
density.
