Answering Calls Calls on
ISDN S/T and U Interfaces
When receiving a call either on the S/T
or on the U interface, the ARGUS
indicates this with the menus displayed
on the left. The number of the caller will
be displayed as well as the TON (type
of number) and NP (numbering plan).
Having ACCEPTed the incoming call, a
conversation can be held. In the end
one can press the CONT. softkey or the
handset button to finish the call (active
clearing). Should the user on the far
end finish the call, the message normal
clearing is put out.
In the end the ARGUS returns to the
main menu associated with the current
mode of operation.
