CFI Sub-Timeslot Position CSCR
If a timeslot assignment is programmed in the control memory (CM), the used control
memory code defines the channel bandwidth and the subchannel position at the PCM
interface (refer to chapter 5.4.2). The subchannel position at the configurable interface
however is defined on a per port basis in the Configurable interface SubChannel
Register CSCR.
The subchannel control bits SC#1 … SC#0 specify separately for each logical port the
bit positions to be exchanged with the data memory (DM) when a connection with a
channel bandwidth as defined by the CM code has been established:

Table 37 shows the effect of the different subchannel control bits SC#1 … SC#0 on the
CFI ports in each CFI mode:

Note: In CFI mode 1:SC21 = SC01; SC20 = SC00; SC31 = SC11; SC30 = SC10
If for example at CFI port 1 a 16 kBit/s channel shall be switched to (or from) a CFI bit
position 5 … 4 from (or to) any 2 bit sub-timeslot position at the PCM interface, a CM
code defining a channel bandwidth of 16 kBit/s and defining the subchannel position at
the PCM interface must be written to the CM code field of the involved 8 bit CFI timeslot
(i.e. 0111, 0110, 0101 or 0100). In order to insert (or extract) bit positions 5 … 4 of the
selected 8 bit CFI timeslot, SC11 … SC10 have to be set to 01. Once fixed to this value,
all timeslot connections programmed on CFI port 1 are performed on bits 7 … 0 for
