No. 6,665,381 and entitled “SELF-CONTAINED DEVICE USING A SINGLE PHONE LINE TO RECEIVE PHONE CALLS AND FACSIMILES WHILE CONNECTABLE TO THE INTERNET”. 
     
    
     FIELD OF THE INVENTION  
       [0002]     The present invention relates to a self-contained device for using a single telephone line to receive telephone calls and facsimiles using distinctive rings. More particularly, the present invention relates to a self-contained device for using a single telephone line to receive telephone calls and facsimiles and recognize and use distinctive ring call waiting signals while being simultaneously connectable to the Internet.  
       BACKGROUND OF THE INVENTION  
       [0003]     Numerous innovations for telecommunication devices have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.  
         [0004]     A FIRST EXAMPLE, U.S. Pat. No. 4,639,553 to Kiguchi teaches a facsimile communication system wherein a call signal detecting device is for identifying call signals which are received over a network. Both an unsounding call signal and a sounding call signal are detected by a single detection circuitry, which is also responsive to off-hooking of an own station&#39;s telephone set. Detection of such signals is implemented by the measurement of a period which is performed by a processing unit, so that changes in the specifications of the signals to be detected can be accommodated merely by modifying a program of the processing system and not the hardware of the device.  
         [0005]     A SECOND EXAMPLE, U.S. Pat. No. 4,856,049 to Streck teaches apparatus for answering an incoming call over a single telephone line and for automatically switching the call between a telephone and a carrier signal-based device as appropriate. There is a three position switch for switching a telephone line connected thereto between first, second and third output positions thereof. The switch has the telephone operably connected to the second output position thereof and the carrier signal-based device connected to the third output position thereof. There is first logic having an input connected to the first output position of the switch and an output operably connected to switch the switch between the first, second and third output positions for answering an incoming call on the telephone line, for determining whether the incoming call is from a carrier signal-based device, for switching the switch to connect the second output position when an incoming call from a non-carrier signal-based device is detected, and for switching the switch to connect the third output position when an incoming call from a carrier signal-based device is detected. There is also second logic having an input connected to sense transmissions from the telephone and the carrier signal-based device and an output operably connected to switch the switch between the first, second and third output positions for switching the switch to the first position when a hang up by the telephone or the carrier signal-based device is detected. The preferred embodiment also senses a pickup by either device and automatically switches the switch to connect the device to the telephone line for outgoing transmission use. The preferred stand alone version also includes telephone answering capability for alerting a caller to its operation and for recording a message if the telephone is not answered.  
         [0006]     A THIRD EXAMPLE, U.S. Pat. No. 5,003,581 to Pittard teaches a control and switching unit used with at least two devices for transmitting information or voice communication over telephone lines. The control and switching unit is provided with a series of relay to ensure that only one of the devices receives or transmits information at anyone time. A timing circuit is utilized such that if one of the devices is a telephone, the second device would not be able to gain access to the telephone line if the telephone is ringing. Additionally, if the telephone is in use, the secondary device, such as a modem, could be selected and this secondary device would gain access to the telephone line after the use of the telephone has been discontinued.  
         [0007]     A FOURTH EXAMPLE, U.S. Pat. No. 5,036,534 to Gural teaches a subscriber&#39;s interface enabling the connection of otherwise incompatible telephone device systems (hereinafter “(Z)”) to a single telephone line, each telephone device system having devices such as: a computer modem (hereinafter “(F)”), an automatic answering machine (hereinafter “(A)”), and telephone sets (hereinafter “(T)”). When a ring signal is received from the central office, the interface allows a first device, such as (A) or (T) to answer the call, and monitors the communication between the calling party and the first device bearing in mind its various operating modes. Based on the monitored conversation, the interface determines if the call should be connected to a second device. If so, an actuating signal is sent to (F), whereupon when (F) becomes OFF HOOK, it is connected to the telephone line. If the first device is an automatic answering machine, its various operating modes include: outgoing message, incoming message, beeperless remote mode. If the first device is a remotely located telephone set, its various mode of operation include simple human voice signals and complex human voice signals.  
         [0008]     A FIFTH EXAMPLE, U.S. Pat. No. 5,392,334 to O&#39;Mahoney teaches a method for processing an incoming call on a telephone line in a computer system, wherein a telephony circuit detects a pick-up by a parallel device coupled to the telephone line while maintaining high voltage isolation. The telephony circuit performs hard line seizures to cause the parallel device to hang-up and soft line seizures to prevent a central office hang up after the parallel device hangs up.  
         [0009]     A SIXTH EXAMPLE, U.S. Pat. No. 5,519,767 to O&#39;Horo et al. teaches a call-waiting feature that is supported on voice-and-data modems by causing voice-and-data modems to go into voice-only mode upon receipt of the modem clear-down signal. A first voice-and-data modem engaged in an initial voice-and-data call with a second voice-and-data modem responds to receipt of a call-waiting signal by generating a replica of the call-waiting signal on the user&#39;s audio channel. The first modem responds to a user request to pick up the waiting call by sending the modem clear-down signal to the second voice-and-data modem, going into voice-only mode, and transmitting a waiting-call acceptance signal. The initial call that is placed on hold is thus a voice-only call. While in a voice-plus-data picked-up waiting call, the first modem responds to a user request to reinstate the initial call by again sending the modem clear-down signal, going into voice-only mode, and transmitting a call-resumption signal. The first modem is thus in voice-only-mode when it is reconnected to the initial, voice-only, call. The reconnected initial call may now be reconverted into a voice-plus-data call in the convention manner.  
         [0010]     A SEVENTH EXAMPLE, U.S. Pat. No. 5,809,128 to McMullin teaches methods and apparatus for providing automatic redirection of an incoming voice telephone call from a caller to a subscriber proxy when an attempt by the caller to connect to a telephone link of a public switched telephone network (PSTN) is blocked due to the telephone link being occupied by a subscriber using the telephone link to establish communication between the subscriber&#39;s personal computer and a computer network. The subscriber proxy is connected to both the PSTN and the computer network, and produces audio interaction with the caller. The subscriber proxy also notifies the subscriber of the incoming call via the subscriber&#39;s computer. The subscriber&#39;s computer can optionally be used by the subscriber to control and interact with the incoming call by communicating with the computer proxy while the subscriber continues to occupy the telephone link.  
         [0011]     AN EIGHTH EXAMPLE, U.S. Pat. No. 6,005,924 to Krexner et al. teaches a fax and phone combination device. The combination device is coupled to an external phone. From a phone line, the combination device receives a call signal, a fax signal, and an information signal. The call signal precedes the fax signal and the information signal. The combination device comprises a fax, an internal phone, and a call signal processor. The call processor processes the call signal received by the combination device and produces a first ringing signal from the call signal. The first ringing signal is intended for the internal phone. The combination device further comprises a ringing signal generator for generating a second ringing signal that is intended for the external phone, and a switch coupled to the fax, the internal phone, and the call processor. A call pulse in the call signal causes the switch to switch the combination device in a simulated receiving mode. In the simulated receiving mode, the fax signal detector detects whether the fax signal is present. If the fax signal is present, the fax signal is routed to the fax. If no fax signal is present, the second ringing signal is routed to the external phone.  
         [0012]     A NINTH EXAMPLE, U.S. Pat. No. 6,067,353 to Szeliga teaches a method and related apparatus for detecting the presence of a call waiting signal on a telephone line, where the call waiting signal is embedded in various signals. The call waiting signal frequency is isolated from the various other frequencies. The isolated call waiting frequency is then biased so that only the positive voltage portions of the signal are allowed to pass. Each positive voltage pulse as well as the zero voltage pulses are then sampled to determine whether they are representative of a biased call waiting signal. Each time a determination is made, one is added to a count on an up-down counter. When the count reaches a predetermined number, a call waiting signal is detected on the telephone line. Preferably an alarm signals the presence of a detected call waiting signal to the user. A disconnect switch interrupts a modem so that a person using the modem on the same telephone line will have sufficient time to answer a detected incoming call.  
         [0013]     A TENTH EXAMPLE, U.S. Pat. No. 6,259,353 to Berger et al. teaches a transponder communication device that interrogates an operational test transponder that is permanently within a receiving range of the transponder communication device. In response thereto, the operational test transponder sends operational test information to the transponder communication device. The transponder communication device checks whether received operational test information is valid, and generates an error signal if the received operational test information is invalid.  
         [0014]     AN ELEVENTH EXAMPLE, U.S. Pat. No. 6,259,692 to Shtivelman et al. teaches a telephony call-waiting system for clients having a computer with a video display unit (PC/VDU) and a public-switched telephony network (PSTN) telephone connected to the PSTN by a single line, keeps a status indication of the client&#39;s Internet connection status and, during periods of time the PC/VDU is connected to the Internet, alerts the client by an alert signal over the Internet connection of any waiting PSTN calls. In a preferred embodiment the client&#39;s PC/VDU is adapted to provide an audio and/or visual alert event when an alert signal is received, and to provide for a user-initiated response to an alert, accepting or rejecting a call. In the event a call is accepted, provision is made for connecting the accepted call to the client&#39;s PC/VDU as an IP call. In some embodiments several calls may be dealt with at the PC/VDU, and features are provided such as caller-ID on the client&#39;s VDU. Several ways of accomplishing the call-waiting system are taught.  
         [0015]     The distinctive ring feature is a service offered by telephone providers. In use, the switching system sends more than one type of ring signal to the telephone line of the user. The distinctive rings may advantageously be used to identify the intended recipient of the call, thus allowing users to decide whether or not to answer the call. As an example, a first distinctive ring may consist of one long ring, indicating a call to a number associated with one member of a house hold. A second distinctive ring consisting of a short ring may indicate a call to the number advertised as a business fax line, and a third distinctive ring consisting of two short rings may indicate a call to a second member of the house hold.  
         [0016]     Systems offering the “distinctive ring” feature generally discuss one of two modes of use of that feature. The first mode is audio only use of the feature, in which the audible ring signal of the telephone is the only cue to the user as to the identity of the intended recipient of the call. This teaches away from the use of a visual cue such as a flashing LED to convey the distinctive ring information. The second mode of use is use of the distinctive ring feature to do fax/phone switching.  
         [0017]     These teach away from the use of a stand alone device to provide the distinctive ring feature along with the capabilities needed to allow a single telephone line to function in conjunction with Internet service. Crucially, they all fail to teach that a stand alone device may provide distinctive ring functionality to an on-line computer user, even though the telephone line may be in use by a modem.  
         [0018]     Furthermore, even though previous innovations may be suitable for the specific individual purposes to which they are addressed they would not be suitable for the purposes of the present invention as hereinafter described.  
       SUMMARY OF THE INVENTION  
       [0019]     ACCORDINGLY, AN OBJECT of the present invention is to provide a self-contained distinctive ring detection and utilization device for using a single telephone line to receive telephone calls and facsimiles and recognition of distinctive rings while being simultaneously connectable to the Internet that avoids the disadvantages of the prior art.  
         [0020]     ANOTHER OBJECT of the present invention is to provide a self-contained device for using a single telephone line to receive telephone calls and facsimiles while being simultaneously connectable to the Internet that is simple to use.

Additionally, the present invention switches between voice and fax calls, automatically and without any intervention from the user. In addition the present invention also permits the user to receive both call an faxes while not on line.  
         [0024]     To achieve the combined functions, the present invention integrates a micro-processor which coordinates general functionality. Tone detection circuitry, which provides extremely narrow and selective detection range and detects the appropriate tones.

     DETAILED DESCRIPTION  
       [0111]     The present invention makes use of the distinctive ring signal and/or distinctive ring call waiting signal offered as a feature by many telephone service providers, to allow simultaneous use of the Internet and the call waiting features. For purposes of this patent application, it will be understood that the terms “distinctive ring signal”, “distinctive call waiting tone”, and the like are used interchangeably herein. In addition, “Internet Service Provider”, “ISP”, or just “service provider” and the like are used interchangeably herein.  
         [0112]     In general, when a user is on-line, they will be enabled by the device of the invention to receive distinctive rings/call waiting signals and then decide, either manually or automatically, whether they wish to break off their Internet session or ignore the telephone call.  
         [0113]     Referring now to the Figures, in which like numerals indicate like parts, and particularly to  FIGS. 1 and 2 , the self-contained device of the present invention is shown generally at  10  for using a single telephone line  12  to receive telephone calls and facsimiles for transmission respectively to a telephone/answering machine  14  and a facsimile machine  16  while being simultaneously connectable to the Internet by a computer  18  that has a modem  19 .  
         [0114]     The self-contained device  10  comprises a single housing  20  that has a back wall  22 .  
         [0115]     The self-contained device  10  further comprises a power supply input  24 . The power supply input  24  is on the back wall  22  of the single housing  20  and is connected by a cable  25  to an AC transformer  26  for connecting to an AC power source  28 .  
         [0116]     The self-contained device  10  further comprises a facsimile jack  30 . The facsimile jack  30  is on the back wall  22  of the single housing  20  and is for connecting to the facsimile machine  16 .  
         [0117]     The self-contained device  10  further comprises a telephone/answering machine jack  32 . The telephone/answering machine jack  32  is on the back wall  22  of the single housing  20  and is for connecting to the telephone/answering machine  14 .  
         [0118]     The self-contained device  10  further comprises a modem jack  34 . The modem jack  34  is on the back wall  22  of the single housing  20  and is for connecting to the computer  18 .  
         [0119]     The self-contained device  10  further comprises a telephone line jack  36 . The telephone line jack  36  is on the back wall  22  of the single housing  20  and is for connecting to a telephone outlet  38 . If a caller ID device  40  is used, the caller ID device  40  is connected between the telephone line jack  36  and the telephone outlet  38 .  
         [0120]     The self-contained device  10  further comprises a power supply  41 . The power supply  41  is contained in the single housing  20  and communicates with the power supply input  24 . The power supply  41  includes a 5 volt voltage regulator  43 .  
         [0121]     The self-contained device  10  further comprises a micro-processor  42 . The micro-processor  42  is contained in the single housing  20  and makes most of the functional decisions. A typical example of the micro-processor  42  is Microchip PIC 16C54.  
         [0122]     The self-contained device  10  further comprises tone detectors  44 . The tone detectors  44  are contained in the single housing  20 , communicate with the micro-processor  42 , and include a fax tone detector  44   a  and a call waiting tone detector  44   b.    
         [0123]     The self-contained device  10  further comprises distinctive ring filter  44   c . Distinctive ring filter  44   c  is contained within the single housing  20  of self-contained device  10 , and may be an independent device, a part of micro-processor  42  or a part of tone detectors  20 . Filter  44   c  may also be a software implementation running on micro-processor  42  within self-contained device  10 . Such a software implementation may be modified and programmed via download from either a telephone line or from an attached computer, or may be modified and programmed by means of hardware on single housing  20 : mode/function buttons, etc. Filter  44   c  recognizes distinctive ring signals received by tone detector  44 .  
         [0124]     Filter  44   c  may utilize DSP, digital signal processing, in the preferred embodiment of the invention. One advantage of DSP is that it in turn facilitates the use of pattern recognition algorithms to compensate for dropped out signal. Such pattern recognition may in turn utilize look up tables and/or fuzzy logic. An example of the functionality of fuzzy logic and look up tables, may be a case in which a user has two distinctive rings programmed, the first distinctive ring being a single short ring signal and the second distinctive ring being a long signal followed by a short signal. Should a ring signal be corrupted by the dropping of a portion of the long ring, it will be received as two short signals. Ordinarily, this would be unrecognizable. However, by the use of fuzzy logic, the two entries on the look up table can be compared and the stand alone device may correctly deduce that the two short signals are more likely to be the second distinctive ring and less likely to be the first distinctive ring.  
         [0125]     The fax tone detector  44   a  detects a fax tone when the self-contained device  10  is in a mode to detect the fax tone. A typical example of the fax tone detector  44   a  is LM567 (National Semiconductor) or NJM567 (New Japan Radio).  
         [0126]     The call waiting tone detector  44   b  is a tone detector with switched capacitor or digital signal processing (DSP) detection that detects a call-waiting tone and also discriminates between the call-waiting tone and modem noise present at that time. The call waiting tone detector  44   b  has selectable frequencies for different tones in other countries. A typical example of the call waiting tone detector  44   b  is Teltone M982- 02 .  
         [0127]     The self-contained device  10  further comprises telephone line isolation and input amplification and filtration  45 . The telephone line isolation and input amplification and filtration  45  are contained in the single housing  20  and communicate with, and between, the tone detectors  44  and the telephone line jack  36 .  
         [0128]     The self-contained device  10  further comprises a tone select  46 . The tone select  46  is contained in the single housing  20  and communicates with the tone detectors  44 .  
         [0129]     The self-contained device  10  further comprises a display and ring buzzer  48 . The display and ring buzzer  48  are contained in the single housing  20  and communicate with the micro-processor  42 . The micro-processor  42  generates tone for the display and ring buzzer  48 .  
         [0130]     The self-contained device  10  further comprises a ring voltage generator  50 . The ring voltage generator  50  is contained in the single housing  20  and communicates with, and between, the display ring buzzer  48  and the facsimile jack  30 .  
         [0131]     The jacks  30 ,  32 ,  34 , and  36  are operatively connected so as to allow transmission of analog or digital information therebetween, thus allowing transmission of such information/data between the telephone line  12  and the various devices attached to the self-contained device  10 . Micro-processor  42  is further able to direct incoming calls by means of the jacks  30 ,  32 ,  34 , and  36  to such attached devices. Finally, micro-processor  42  and/or filter  44   c  is/are able to control the operation of display/buzzer  48 .  
         [0132]     Referring now to  FIG. 3 , the method of use of distinctive ring will now be discussed. The steps in this process are as follows: 
    STEP 1: Action is initiated when self-contained device  10  detects a ring signal.     STEP 2: Filter  44   c  then identifies the specific distinctive ring of the ring signal.     STEP 3: Microprocessor  42  thereafter uses the distinctive ring signal to determine and display the recipient of the incoming call by means of the distinctive ring.    
 
         [0136]     This basic process may be employed in any of the embodiments of the invention discussed below, at the step of detecting a ring signal and using display/ring buzzer  48  to convey the information regarding intended recipient to the user. The enhancements this offers will be further discussed in reference to each of the following embodiments.  
         [0137]     In the preferred embodiment and best mode presently contemplated for carrying out the invention, microprocessor  42  will display using display  48  the distinctive ring signal. This signal may, in one embodiment, be a sequence of rings offered by the telephone service provider as part of the distinctive ring package. Such rings may be distinguished by length of ring, number of rings, pattern, length of silences within the rings, tone and/or other qualities. Display/buzzer  48  may have a visual component such as a light or LED which lights up (or “flashes”, however, this use of the word “flash” should not be confused with the telephone control “flash” used to switch lines). Thus the LED or light provides the same ring information as the distinctive ring, for example by means of length of lighting up, number of flashes, pattern, length of periods between flashes, color and/or other qualities.  
         [0138]     Ring buzzer  48  may be used in alternative embodiments either with the LED/light display or by itself. This buzzer may directly mimic the sounds produced by the distinctive ring signal itself, or it may provide other more easily distinguished patterns.  
         [0139]     The distinctive ring information detected and recognized by the stand alone device  10  of the invention may be used in addition during the “determination” steps described below. In particular, the distinctive ring may be used in one alternative to route incoming calls automatically based on whether the distinctive ring identifies a call that is coming to a “facsimile recipient” or a “voice recipient” or a “modem recipient”. This function may be carried out based upon information provided during the set-up of the device. In further particular, in yet another alternative embodiment the distinctive ring may be used to answer or ignore incoming calls based upon the distinctive ring and information provided during the set-up of the device.  
         [0140]     Referring now to  FIGS. 4A-4D , the method of use of the device will now be discussed. 
    STEP 1: Ascertain that the self-contained device  10  is connected to the AC power source  28  by illumination of a power light on the front of the single housing  20 .     STEP 2: Log online.     STEP 3: Ascertain that the computer  18  is online by illumination of a modem light on the front of the single housing  20 .     STEP 4: Ring and flash a call light when the self-contained device  10  detects a call waiting signal.     STEP 5: Determine if call is to be answered.     STEP 6: Lift the handset of the telephone connected to the self-contained device  10 , if answer to STEP 5 is yes.     STEP 7: Flash automatically the telephone line  12  and connect to the caller, placing automatically the Internet provider on hold.     STEP 8: Hang up the telephone once finished with the call.     STEP 9: Reflash automatically the telephone line  12  and connect the computer  18  back to the Internet provider.     STEP 10: Determine if the service provider has logged off the computer  18 . It is not unusual for the Internet service provider to disconnect within a short period.     STEP 11: Reconnect if answer to STEP 10 is yes.    
 
         [0152]     It will be seen that during STEP 4 of the method of  FIG. 4 , the distinctive ring may be employed either by the buzzer or by the call light to indicate to the user the identity of the intended recipient. During STEP 5, determination of whether the call should be answered or not, the user may profitably employ this information in manually determining whether or not to temporarily suspend the Internet session by means of the abilities offered by self-contained device  10 . In this embodiment, the distinctive ring information is sent to the user by means of display/buzzer  48  in order to allow the user to make the decision how to handle the call.  
         [0153]     There is an additional use of the distinctive ring made possible by the invention. The handling of the incoming call may be determined automatically based upon the identity of the intended recipient. For example, the user may program the device during set-up so as to automatically suspend Internet access in accordance with the invention when the distinctive ring identifies an incoming call as being intended for a business recipient, however, the self-contained device  10  may automatically ignore the incoming call if intended for a family-member&#39;s personal reception, and may request user input in the determination if the incoming call is intended for a facsimile reception.  
         [0154]     The method of operation of the self-contained device  10  when used with the facsimile machine  16  can best be seen in  FIGS. 5A-5B  and  6 A- 6 G, and as such, will be discussed with reference thereto. Note that in the following embodiment of  FIG. 5 , the distinctive ring signal may be used to provide users with call recipient information, even though the routing of fax versus voice recipients (discussed in reference to  FIG. 4 ) may not be utilized. 
    STEP 1: Listen for a fax tone any time there is an incoming call regardless if the incoming call is answered by either picking up the telephone, the answering machine, or in a call waiting call.     STEP 2: Determine if the incoming call is a voice.     STEP 3: Ignore the incoming call, if answer to STEP 2 is yes.     STEP 4: Determine if the incoming call is a fax, if answer to STEP 2 is no.     STEP 5: Ring immediately the facsimile machine  16 , if answer to STEP 4 is yes.     STEP 6: Transfer the incoming call to the facsimile machine  16 , if STEP 5 is carried out.    
 
         [0161]     The method of installing the self-contained device  10  can best be seen in  FIGS. 7A-7E , and as such, will be discussed with reference thereto. 
    STEP 1: Connect the cable  25  into the power supply input  24 .     STEP 2: Plug the AC transformer  26  into the AC power source  28 .     STEP 3: Illuminate a power light on the front of the single housing  20 , which indicates that the self-contained device  10  is operational.     STEP 4: Disconnect the telephone cord of the computer  18  from the telephone outlet  38 .     STEP 5: Plug the telephone cord from the computer  18  into the modem jack  34 .     STEP 6: Plug the telephone into the answering machine.     STEP 7: Plug the cord of the answering machine into the telephone/answering machine jack  32 .     STEP 8: Plug one end of the telephone cord into the telephone line jack  36 .     STEP 9: Plug the other end of the telephone cord into the telephone outlet  38 .     STEP 10: Determine if the self-contained device  10  is being used with a facsimile machine  16 .     STEP 11: Plug the facsimile cord into the facsimile jack  30 . if answer to STEP 10 is yes.     STEP 12: Set the facsimile machine  16  to answer automatically and proceed to     STEP 14, if STEP 11 is carried out. The facsimile machine  16  will only respond to an incoming call when the self-contained device  10  transfers the incoming call to the facsimile machine  16 . The facsimile machine  16  will no longer answer when the telephone rings.     STEP 13: Proceed to step 14, if answer to STEP 10 is no.     STEP 14: Set the answering machine to answer on two rings.     STEP 15: Ascertain that call waiting is not disabled.

         [0217]     During set-up of certain alternative embodiments of the invention, the user may in addition wish to direct the invention as to handling of incoming calls based upon recipient identity. Thus, the “Internet suspension” operation, STEP 7 of  FIG. 4  may be enabled in certain cases and not in others, while the set-up operations of the self-contained device  10  may direct the methods of ringing/flashing the buzzer/call light  38  during STEP 4 of  FIG. 4 . In addition, STEP 5 of  FIG. 4 , in which the determination as to whether a call is to be answered or not is made, may be designated automatically based upon the distinctive ring signal received.  
         [0218]     This additional set-up may be carried out in hardware (for example, by means of buttons on the self-contained unit  10 ) or may be carried out by means of software on a personal computer, with the settings generated by the personal computer then downloaded to the self-contained device  10 . Note that the setting information may then be present in self-contained device  10  even when a computer is turned off, disconnected, broken or otherwise unavailable during an incoming call. This facet of the self-contained operation is felt to be a marked improvement over devices teaching use of a personal computer to handle incoming distinctive ring information.  
         [0219]     The disclosure is provided to allow practice of the invention by those skilled in the art without undue experimentation, including the best mode presently contemplated and the presently preferred embodiment. Nothing in this disclosure is to be taken to limit the scope of the invention, which is susceptible to numerous alterations, equivalents and substitutions without departing from the scope and spirit of the invention. The scope of the invention is to be understood from the appended claims.
