Framing Bit Counter. This eight bit counter will be incremented for each error in the
received framing pattern. In ESF mode the ESF framing bits are monitored. In D4 mode Fs
bits may be monitored as well as Ft bits. See - Section 15.5 Framing Bit Counter. The count
is only active if the 3VJET is in synchronization.
