17.2.9
Table 191 describes the bit functions of each (30 registers in total, one register for each PCM 30 channel) of the
Receive CAS Data Registers in the MT9072. Each register is repeated for each of the 8 framers. Framer 0 is
addressed with Y=0, Framer 1 with Y=1, Framer 2 with Y=2 and so on up to Framer 7 with Y=7 (where Y represents
the 4 most significant address bits (MSB) A11-A8).
A (0), (1) or (#) in the “Name” column of these tables indicates the state of the data bits after a reset (RESET, RSTC
or RST). The (#) indicates that a (0) or (1) is possible.
17.2.10
Table 191 describes the bit functions of each (32 registers in total, one register for each timeslot) of the Timeslot
Control Registers in the MT9072. Each register is repeated for each of the 8 framers. Framer 0 is addressed with
Y=0, Framer 1 with Y=1, Framer 2 with Y=2 and so on up to Framer 7 with Y=7 (where Y represents the 4 most
significant address bits (MSB) A11-A8). In addition, a simultaneous write to all 8 framers is possible by setting the
MSB address to Y=8 (1000). Note that timeslots 0 to 15 are accommodated by addresses Y90 to Y9F respectively,
and timeslots 16 to 31 are accommodated by addresses YA0 to YAF respectively.
A (0), (1) or (#) in the “Name” column of these tables indicates the state of the data bits after a reset (RESET, RSTC
or RST). The (#) indicates that a (0) or (1) is possible.

For these functions to be valid, CAS mode must be selected (CSIG=0 register address Y03).

Receive Alternate Digit Inversion. the data received on DSTo timeslot n from the
received PCM30 link timeslot n has every second bit inverted. If zero, this bit has no effect
on channel data.
Micro Port Data Receive. Setting this bit freezes the receive data for a given channel
After putting the freeze the data (Y09).
not used.
Receive Channel Associated Signaling (CAS) Signaling Bits for Channel 1 to 30.
Bits for n=1 to 15 correspond to channel 1 to 15 and are received on the PCM30
link in timeslot 16 in bit positions one to four in frame n.
Bits for n=17 to 31 correspond to channel 16 to 30 and are received on the PCM30
link in timeslot 16 in bit positions five to eight in frame n -16.
