Framer Register Architecture
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 76. Facility Event Register (FRM_SR7) (Y07)
* 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 77. Bipolar Violation Counter Registers (FRM_SR8—FRM_SR9) (Y08—Y09)
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.

Out of Unavailable State. A 1 indicates the receive framer detected ten consecutive
seconds 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
consecutive 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 con-
secutive 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 con-
secutive 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
specified 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
Receiving Quasi-Random Pattern. A 1 indicates the receive framer pattern monitor cir-
cuit is currently detecting the 2
