TFRA08C13 OCTAL T1/E1 Framer
Framer Register Architecture
Remote End Alarm Register (FRM_SR2)
A bit set to 1 indicates the receive framer has recently received the given alarm. Interrupts from this register are
generated once at the beginning of the alarm condition. If the alarm is still present at the time of the read, the bit
will remain in the 1 state for the duration of the alarm condition. If the alarm condition is no longer present at the
time of the read, then the bit is cleared on read.

Remote Multiframe Alarm. A 1 indicates the receive framer detected a time slot 16
remote frame alarm in the CEPT mode.
Continuous Received E Bits. A 1 indicates the detection of a five-second interval con-
taining 991 E bit = 0 events in each second. This bit is 0 in the DS1 mode.
Received Sa6 = 8. A 1 indicates the receive framer detected an Sa6 code equal to 1000.
This bit is 0 in the DS1 mode.
Received Sa6 = A. A 1 indicates the receive framer detected an Sa6 code equal to
1010. This bit is 0 in the DS1 mode.
Received Sa6 = C. A 1 indicates the receive framer detected an Sa6 code equal to
1100. This bit is 0 in the DS1 mode.
Received Sa6 = E. A 1 indicates the receive framer detected an Sa6 code equal to
1110. This bit is 0 in the DS1 mode.
Received Sa6 = F. A 1 indicates the receive framer detected an Sa6 code equal to 1111.
This bit is 0 in the DS1 mode.
