Bit 5/Transmit T3 Idle Signal Enable (T3IDLE).
When this bit is set high, the T3 Idle Signal will be
transmitted instead of the normal transmit data. The T3 Idle Signal is defined as a normally T3 framed
pattern (i.e., with the proper F bits and M bits along with the proper P bits) where the information bit
fields are completely filled with a data pattern of ...1100... and the C bits in Subframe 3 are set to zero and
both X bits are set to one. This bit is ignored in the E3 mode.
0 = transmit data normally
1 = transmit T3 Idle Signal
Bit 6/T3/E3 Line Loopback Enable (LLB).
See Figures 1A and 1B for a visual description of this
loopback.
0 = disable loopback
1 = enable loopback
Bit 7/T3/E3 Diagnostic Loopback Enable (DLB).
See Figures 1A and 1B for a visual description of this
loopback.
0 = disable loopback
1 = enable loopback
Bit 8/E3 Code Violation Enable (E3CVE).
This bit is ignored in the T3 mode. This bit is used in the E3
mode to configure the BiPolar Violation Count Register (BPVCR) to count either BiPolar Violations
(BPV) or Code Violations (CV). A BPV is defined as consecutive pulses (or marks) of the same polarity
that are not part of a HDB3 code word. A CV is defined in ITU O.161 as consecutive BPVs of the same
polarity.
0 = count BPV
1 = count CV
Bits 9 and 10/T3/E3 Frame Error Counting Control Bits 0 and 1 (FECC0 and FECC1).
