framing and balancing bit.
7.2.6.3 FAinfD_1fr
frame remains at binary "1" until the first B2 bit which is bit position 16. The pulse sequences are: Framing bit,
balancing bit, B2 bit, M bit, S bit, balancing bit. The TE should reflect the received F
transmitted frame.
This test checks if TE does not lose frame alignment on receipt of one IX_I4noflag frame which has no
