The STCR-register bits are used to enable or disable the synchronous transfer utility and
to determine the sub time slot bandwidth and position if a PCM-interface time slot is
involved.

Channel Type A (B); these bits determine the bandwidth of the channel and
the position of the relevant bits in the time slot acoording to the table below.
MTXB6
Interface Select Transmit for channel B.
0… selects the PCM-interface as the output interface for synchronous
1… selects the CFI-interface as the output interface for synchronous
number at the interface selected by ISXB according to tables 16 and 17:
MTXB6..0 = MA6..0.
1… enables the P transfer of the corresponding channel.
0… disables the P transfer of the corresponding channel.
