MF Channel Subscriber Address Register
MFSAR: MFTC1 MFTC0
The exchange of monitor data normally takes place with only one subscriber circuit at a
time. This register serves to point the MF handler to that particular CFI time slot.
MFTC1 … 0:
SAD5 … 0:
CFI time slot encoding of MFSAR derived from MAAR:
MFSAR: MFTC1 MFTC0 SAD5
MAAR:MA7 selects between upstream and downstream CM blocks. This information is
not required since the transfer direction is defined by CMDR (transmit or receive).
MAAR:MA0 selects between even and odd time slots. This information is also not
required since MF channels are always located on even time slots.

bit 7
MAAR:
MF Channel Transfer Control 1 … 0; these bits, in addition to
CMDR:MFT1,0 and OMDR:MFPS control the MF channel transfer as
indicated in table 32.
Subscriber address 5 … 0; these bits define the addressed
subscriber. The CFI time slot encoding is similar to the one used for
Control Memory accesses using the MAAR register (see figure 48).
