NAME AND DESCRIPTION
RLOSC
RIR2.7
Receive Loss of Sync Clear. Set when the framer achieves
synchronization; will remain set until read.
RCLC
RIR2.6
Receive Carrier Loss Clear. Set when the carrier signal is
restored; will remain set until read. See Table 7-1.
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.
RBLC
RIR2.2
Receive Blue Alarm Clear. Set when the Blue Alarm (AIS)
is no longer detected; will remain set until read. See Table 7-1.
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.
