MFD Multiframe Disable
This bit is used to enable or disable the multiframe structure on S/T interface:
0 : Multiframe is enabled
1 : Multiframe is disabled
DLP Digital Loopback
Setting this bit activates the digital loopback function. The transmitted digital 2B+D channels are
looped to the received 2B+D channels. Note that after hardware reset, the internal clocks will turn off
if the S bus is not connected or if there is no signal on the S bus. In this case, the C/I command ECK
must be issued to enable loopback function.
RLP Remote Loopback
Setting this bit to "1" activates the remote loopback function. The received 2B channels from the S
interface are looped to the transmitted 2B channels of S interface. The D channel is not looped in
this loopback function.

CNT together with VAL determine the time period T2 after which a TEXP interrupt will be generated:
T2 = CNT * 2.048 s + T1 with T1 = (VAL +1) * 0.064 s
The timer is started by setting the STT bit in D_CMDR and will be stopped when a TEXP interrupt is
generated or the D_TIMR register is written.
Note: If CNT is set to 7, a TEXP interrupt is generated periodically at every expiration of T1.
This register can be read only after the timer has been started. The read value indicates the timer's
current count value. In case layer 1 is not activated, a C/I command "ECK" must be issued in addition
to the STT command to start the timer.
