Framer Register Architecture
(continued)
Bit 0—bit 4 in this register are set high when the receive framer comes out of the unavailable state, while bit 4—
bit 7 report detection of the receive test patterns. Bits 4 and 5 are cleared only after register FRM_PR70 bit 2 is set
to 0.
Table 95. Facility Event Register (FRM_SR7) (607; C07)
* It is possible for one of these bits to be set to 1, if the received line data is all zeros.
Bipolar Violation Counter Register (FRM_SR8—FRM_SR9)
This register contains the 16-bit count of received bipolar violations, line code violations, or excessive zeros.
Table 96. Bipolar Violation Counter Registers (FRM_SR8—FRM_SR9) ((608—609); (C08—C09))
Frame Bit Errored Counter Register (FRM_SR10—FRM_SR11)
This register contains the 16-bit count of framing bit errors. Framing bit errors are not counted during loss of frame
alignment.
Table 97. Framing Bit Error Counter Registers (FRM_SR10—FRM_SR11) ((60A—60B); (C0A—C0B))

Description
Out of Unavailable State.
A 1 indicates the receive framer detected ten consecutive sec-
onds that were not severely errored while in the unavailable state at the ET.
Out of Unavailable State at the ET-RE.
A 1 indicates the receive framer detected ten con-
secutive seconds that were not severely errored while in the unavailable state at the ET-RE.
Out of Unavailable State at the NT1.
A 1 indicates the receive framer detected ten consec-
utive seconds that were not severely errored while in the unavailable state at the NT.
Out of Unavailable State NT1-RE.
A 1 indicates the receive framer detected ten consecu-
tive seconds that were not severely errored while in the unavailable state at the NT-RE.
Test Pattern Detected.
A 1 indicates the pattern detector has locked onto the pattern spec-
ified by the PTRN configuration bits defined in register FRM_PR70.
Test Pattern Bit Error.
A 1 indicates the pattern detector has found one or more single bit
errors in the pattern that it is currently locked onto.
Receiving Pseudorandom Pattern.
A 1 indicates the receive framer pattern monitor circuit
is currently detecting the 2
15
– 1 pseudorandom pattern*.
Receiving Quasi-Random Pattern.
A 1 indicates the receive framer pattern monitor circuit
is currently detecting the 2
20
– 1 quasi-random pattern*.
