TFRA08C13 OCTAL T1/E1 Framer
Framer Register Architecture
The following status registers are dedicated to the NT1 and the NT1 remote end (NT1-RE) interface. The alarm
conditions to evaluate errored seconds and severely errored seconds are defined in Table 32 and the NT1 and
NT1-RE enable registers, FRM_PR16—FRM_PR18. The thresholds are defined in registers FRM_PR11—
FRM_PR13.

Register (FRM_SR6) (Y06)

NT Errored Second. A 1 indicates the receive framer detected an errored second at the
network termination (NT).
NT Bursty Errored Second. A 1 indicates the receive framer detected a bursty errored
second at the NT.
NT Severely Errored Second. A 1 indicates the receive framer detected a severely
errored second at the NT.
NT Unavailable State. A 1 indicates the receive framer has detected at least ten consec-
utive severely errored seconds. Upon detecting ten consecutive nonseverely errored sec-
onds, the receive framer will clear this bit. ITU Recommendation G.826 is used resulting
in a ten-second delay in the reporting of this condition.
NT-RE Errored Second. A 1 indicates the receive framer detected an errored second at
the exchange termination remote end (ET-RE).
NT-RE Bursty Errored Second. A 1 indicates the receive framer detected a bursty
errored second at the ET-RE.
NT-RE Severely Errored Second. A 1 indicates the receive framer detected a severely
errored second at the NT-RE.
NT-RE Unavailable State. A 1 indicates the receive framer has detected at least ten
consecutive severely errored seconds. Upon detecting ten consecutive nonseverely
errored seconds, the receive framer will clear this bit. ITU Recommendation G.826 is
used resulting in a ten-second delay in the reporting of this condition.
