9.3 Programming the MSC Protocol
The MSC protocol configuration is identical to the QMC configuration with the exception
of the time slot assignment tables. Figure 9-3 shows the addition of the L bit needed for the
MSC configuration. Note that it is possible to have up to 32 channels coming from any
permutation of the time slots.

As the L bit (bit 11 of a time slot assignment table entry) is
taken from the original channel pointer field, the addressing
capability of the QMC is reduced from 6 bits (64 channels) to
5 bits (32 channels) for receive and transmit.
