comprises an active traffic channel.
^SLCC:
End of current list
RING
Incoming call is signalled.
^SLCC: 1,1,4,0,0,1,''1234567'',129
The incoming call had a traffic channel assigned
from the start.
This second identical display is triggered by the traf-
fic channel assignment.
Since the traffic channel was already indicated in the
previous URC, both instances of the URC contain
identical information.
