Definitions
- the present invention relates to telecommunications, and more particularly, to a private branch exchange (PBX) and a method for operating the PBX to provide voice, FAX, and modem services utilizing a single telephone number.
- PBX private branch exchange
- a business person In the age of modern communications, a business person has typically two and often three telephone numbers. The first is for conventional voice communications, the second is for receiving F ⁇ X transmissions, and the third is for data communications via modem.
- the FAX transmissions In a typical office setting serviced by a PBX, the FAX transmissions are directed to a FAX server which is determined by the telephone number to which the FAX transmission is directed. Since the number of FAX lines that are reserved in any system is much smaller than the number of voice lines, FAX transmissions for a number of recipients are printed at the same FAX machine and are then delivered to the various recipients.
- FAX transmissions lack privacy. This lack of privacy can be a problem in many settings. For example, in communications between a lawyer and her client, a transmission to the client at his place of business may expose confidential material to the office personnel, and, in some instances, may even lead to a waiver of the attorney-client privilege.
- the FAX server can direct the FAX to the called party.
- This solution also requires the sender to insert information specifying the called party. There is no standard format for such called party identification information. Hence, the caller must be familiar with the particular system used by each recipient.
- PBX PBX system
- FAX FAX
- modem communications PBX system in which a single telephone number can be used for voice, FAX, and modem communications while providing the same level of privacy for FAX and modem communications as provided for voice communications.
- a PBX provides voice and FAX services (as well as modem services, if desired) utilizing only a single DID for each local voice line being serviced.
- FAX and modem servers can be connected to the PBX for directing FAX and data transmissions, respectively, to the intended called party.
- a PBX connects any of a plurality of incoming lines to any of a plurality of local lines with each local line being identified by a DID received in a call setup message on the incoming line.
- the PBX includes means for storing information associating a FAX line with each DID, means for identifying an incoming call as being either a FAX transmission or a voice call, and means for connecting the incoming call to the FAX line associated with that DID if the incoming call is identified as a FAX transmission. If the FAX line is connected to a FAX server that can route the received FAX transmissions to a destination provided in a FAX header, the present invention inserts the routing information associated with the DID into the header. Modem communications are handled in a manner analogous to FAX transmissions.
- Figure 1 is a block diagram of the preferred embodiment of a PBX call discrimination system according to the present invention.
- FIG. 1 is a block diagram of one embodiment of the present invention.
- PBX 10 includes a data collector 20, a call identifier 30, a plurality of FAX server ports 40, a plurality of modem server ports 50, and a plurality of telephone line extension ports 60.
- Preferably one DID is available for each called party on the PBX. Each DID may be associated with a voice call extension and a FAX line port, as well a modem line port, which are preassigned to each called party being serviced by the PBX.
- This information is stored by data collector 20.
- Data collector 20 is coupled to the incoming telephone lines 70 to receive the incoming call identification information contained in the call setup information associated with each incoming telephone call. This information includes the DID number identifying the called party.
- the manner in which the call identification information is received will, in general, be determined by the type of telephone service.
- the DID is received on the incoming line as a series of tones.
- the call setup information is transmitted in a separate channel from that used for the telephone connection.
- the incoming call may be either a FAX transmission, a data transmission, or a voice call.
- data collector 20 collects the called party information, and matches the particular DID with the associated FAX port extension, modem port extension, and voice call extension for the intended recipient of the transmission or call.
- the called party information and the extension information is collectively referred to as integration information.
- the incoming call is sent to call identifier 30.
- the manner in which call identifier 30 operates will, in general, depend on the type of telephone service.
- ISDN lines may utilize a protocol that identifies the call as being a voice, FAX or a data call. In this arrangement, the incoming ISDN line is routed based on the protocol.
- call identifier 30 includes circuits for detecting an audible tone associated with FAX and modem transmissions. The type of tone detected identifies whether the call is a FAX transmission or a data transmission. If no tone is detected, call identifier 30 assumes that the call is a voice call. If a voice call is identified, the call is routed in the conventional manner to the called party's preassigned telephone extension 60.
- call identifier 30 routes the call from PBX 10 to a FAX line on FAX server 80.
- FAX server 80 is coupled to PBX 10 at a plurality of FAX server ports 40.
- call identifier 30 routes the call from PBX 10 to a modem server 90.
- Modem server 90 is preferably coupled to PBX 10 at a plurality of modem server ports 50.
- the call identifier 30 detects FAX or data tones when the incoming call is being answered by the called party.
- an incoming call is directed to an extension as a normal call, but when the called party answers, the call identifier 30 determines the type of call by monitoring for FAX or data tones. If a voice call is detected, the call is connected in a normal fashion. If a FAX or a data call is detected, the PBX intercepts the call and routes it to the proper device or server with the integration information. Moreover, as an option, the PBX can play a pre-recorded announcement to signal to the called party that a FAX or a data call has arrived and is being routed to the proper device. Instead of a voice announcement, this notification can be done in the form of text display if the called party uses a display telephone.
- call identifier 30 is not used and the PBX provides additional features.
- the PBX configures a feature code for the subscriber/called party.
- the subscriber can inform the PBX of the type of call by using the feature code.
- This feature code allows the PBX to automatically connect the call to the predefined FAX or data handling destination while avoiding a call transfer.
- the feature code can, for example, be a button, identified as a "FAX" button, on the subscriber's telephone. Thus, when the subscriber presses the "FAX" button, the call is immediately connected to the FAX handling destination. A call transfer is not acceptable because the call may be dropped during the time needed for the transfer.
- the activation of call redirection by call identifier 30 can be configured in a switch (e.g., a PBX switch or a central office switch.
- the activation of call redirection without call identifier 30 can also be configured in a switch.
- the integration information is provided from data collector 20 to FAX server 80 and modem server 90, respectively. This information may be provided via a data link 100; however, any means that is compatible with the particular servers may also be used for this purpose.
- FAX server 80 receives the integration information (i.e., called party information and the extension of the FAX server port preassigned to the called party) at approximately the same time it receives the FAX transmission routed from call identifier 30. Accordingly, FAX server 80 is informed that the incoming FAX transmission being received on a particular FAX server port 40 is intended for a particular called party. Additionally, upon recognizing the called party information received from data collector 20, FAX server 80 can then direct the incoming FAX transmission to the desired called party.
- the manner in which the integration information is delivered to the servers will, in general, depend on the type of server. For example, if the FAX server is capable of extracting the integration information from the FAX header, then data collector 20 will insert the information into the FAX header in the format expected by the server. In this case, the integration information is provide in the header rather than by data link 100.
- FAX server 80 may also utilize a FAX mail system which routes the FAX transmission directly to the called party's computer. Such a system drastically reduces breaches of privacy discussed above with reference to conventional FAX systems servicing multiple users.
- a FAX E- mail system may be programmed to notify the called party via his computer that a FAX transmission is being received for him at a preassigned, secured FAX machine.
- modem server 90 receives integration information from data collector 20 via data link 100 while receiving a data transmission directed to a DID. The data transmission is routed to one of the modem server ports 50 from call identifier 30. Modem server 90 then directs the data transmission received on a particular modem server port 50 identified in the integration information to the desired called party's computer.
- the subscriber can determine or change the FAX or data handling destination. This is done by entering a telephone number associated with the desired FAX or data handling destination.
- the desired FAX or data handling destination can be identified by either a local or a outside telephone number.
- the subscriber enters a special code number for changing handling destinations and then enters the desired telephone number.
- commands for changing the handling destination can be provided through a voice mail system. In this situation, the new telephone number is still communicated directly to the PBX such that the PBX can change the routing path for that subscriber.
- the redirection is configured in a switch (e.g., a PBX switch or a central office switch).
- the above described PBX provides a call discrimination system in which voice and FAX, or voice and modem are provided utilizing only a single DID for each called party serviced by the PBX.
- the PBX receives incoming calls and is able to discriminate or identify whether that call is a voice call, a FAX transmission, or a data transmission, and then routes that call to a preassigned voice, FAX, or data line, respectively.
- Conventional FAX and modem servers are able to receive the transmissions and to direct the transmissions to the intended called party based on the information provided to them by the PBX's data collector.
- the present invention reduces the number of DIDs which must be provided by the PBX and is capable of providing the same level of privacy for FAX and modem transmissions as is provided for voice communications.
- the PBX limits the need for the sender and called party to have the same FAX and modem protocols, since the translation of the integration information to the format expected by the server is accomplished by the data collector which "knows" the type of server connected to the PBX.
