TRANSMIT INTERNATIONAL AND NATIONAL DATA
Bit 1 of timeslot 0 in all frames is known as the international bit. When TCR.4 = 1, the transmitted
international bit is sourced from TINR.7. When TCR.4 = 0, the transmitted international bit is sampled at
TIND during the first bit period of each frame. The international bit positions in all outgoing frames
except 13 and 15 are replaced by CRC4 code words and the CRC4 multiframe alignment signal when
CCR.3 = 1.
