Getting the source slot: nbcsStswGetSrcSlot
This function returns the source space/time slot(s) map to the destination space/time slot(s) from
the offline connection page directly from the hardware device. It operates in either of the two
modes, unicast or map mode controlled by the parameter
For space switch (found in NSE devices) operating in unicast mode, the inport mapped to the
given outport in time instance (first element pointed to by
pointed to by
map mode, the entire connection map is returned to the buffer supplied by the user via
The order in the array is as follows: inport0[0]…inport0[N-1] inport1[0]…inport1[N-
1]…inportM[0]…inportM[N-1] where M = frame size - 1 and is 1079 in TeleCombus/SBI
column or 9719 in SBI DS0/CAS mode and N = total number of ports, i.e., 12 for NSE-8G or 32
for NSE-20G. The only two valid access modes are NBCS_STSW_UNICAST and
NBCS_STSW_MAP.
