The status on SDR is synchronized to SDX. Each time-slot on SDR carries the
corresponding LD bit during the last 20 bits of the slot.

The data on SDX is interpreted as follows:
NOP:
PDOW:
RANGE:
LOOP:
SY:
"0":
The 2B1Q data is coded with the bits TD2, TD1, TD0:
Data Sheet
RANGE activates the range function which attenuates the received U-
First bit of the time-slots with transmission data. For synchronization and
The no-operation-bit is set to ’0’ if none of the control bits (PDOW,
RANGE and LOOP) shall be changed. The values of the control bits of the
assigned line port is latched. The states of the control bits on SDX are
ignored, they should be set to ’0’ to reduce any digital cross-talk to the
analog signals.
The NOPQ bit is set to ’1’ if at least one of the control bits shall be
changed. In this case all control bits are transmitted with their current
values.
If the PDOW bit is set to ’1’, the assigned line port is switched to power-
down. Otherwise it is switched to power-up.
signal
’1’= RANGE function is activated (short line)
’0’= RANGE function is deactivated (long line)
LOOP = ’1’ activates the loop function, i.e. the loop is closed. Otherwise
the line port is in normal operation.
bit allocation on SDX, SY is set to ’1’ on SDX and ’0’ on SDR.
Reserved bit. Reserved bits are currently not defined and shall be set to
’0’. Some of these bits may be used for test purposes or can be assigned
to a function in later versions.
