Timeslot 31 CST Map Bits.
The selection of these bits results in a mapping of the transmit
PCM30 timeslot 31, from a specific CSTi timeslot; and similarly, maps receive PCM30 timeslot
31, to a specific CSTo timeslot. PCM30 timeslot 31 data is mapped to/from CST channel n
(n=0 to 31), where n is the BCD (Binary Coded Decimal) equivalent of 31C4 to 31C0 with 31C4
being the most significant bit.

CCS (CSIG=1 of register address Y03) and CST (TS31E=1 of register address Y06) must be
selected for these operations to be valid.
Timeslot 16 CST Map Bits.
The selection of these bits results in a mapping of the transmit
PCM30 timeslot 16, from a specific CSTi timeslot; and similarly, maps receive PCM30 timeslot
16, to a specific CSTo timeslot. PCM30 timeslot 16 data is mapped to/from CST channel n
(n=0 to 31), where n is the BCD equivalent of 16C4 to 16C0 with 16C4 being the most
