Incoming call is signalled.

Display is triggered by the incoming call, but the cur-

rent status of the call at the time of display already

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.
