Detecting Incoming Voice, Data, or Fax Telephone Calls

      Disclosed is method to support connections with voice
telephones, facsimile transmitters, and data modems, providing access
through a single telephone number to an intelligent communication
system having voice, fax, and data services.

      The Figure is a block diagram of an intelligent communication
system 1, providing access for subscribers over an access line 2
having a single telephone number, through the PSTN 3 (Public Switched
Telephone Network), to various sources of data, such as a voice
telephone 4, a facsimile transmitter 5, and a computer 6 sending and
receiving digital data through a modem 6a.  These types of data may
also be provided by wireless devices 7 and 8 connected to the PSTN 3
over a wireless network 9.  Communication system 1 includes a voice
switch 10, a number of adapter units 11, which may be, for example,
IBM* 9291 or 9295 adapter units, a call processing unit 12, a voice
server 13, a fax server 14, and a data server 15.  The call control
processing unit 12 is used, along with the tone detector in switch
10, to correctly route each call to an appropriate server 13, 14, or
15.  This processing unit 12 interacts with the servers through a
Local Area Network 16 (LAN) or other communications facility.

      When an incoming call arrives from a fax machine 5, the
standard fax tone is detected, so that the call is routed to the fax
server 14.  Optionally, a Common Channel Signalling (CCS) link 16 to
call control processing unit 12 provides the calling number, which is
stored at th...
