Function
Transmit Signaling Marker
Marks the transmit time slots which are defined
by register TTR1-4 of every frame transmitted
on port XDI. In 4096 kbit/s mode, XSIGM is
active only during the channel phase which is
selected by RC0.SICS.
T1 mode/CAS-BR:
If CAS-BR is selected by FMR1.SIGM = 1, the
robbed bit of each channel every six frames is
marked, if marker is enabled by setting
XC0.BRM = 1.
Transmit Multiframe Synchronization
This port defines the first frame of the multiframe
on the transmit system interface port XDI.
Note: A new multiframe position has been
settled at least one multiframe after pulse XMFS
has been supplied.
If this input is not used, it has to be connected to
V
internally.
SS
. In this case multiframe start is generated
