    Apparatus and method for displaying the condition, status, and activity of a cable modem}
    BACKGROUND OF THE INVENTION Field of the Invention The present invention generally relates to a cable modem operating status display and a method for displaying conditions or conditions of a cable modem, and more particularly to providing data desired by a cable modem user in an intuitive, easily read and understood format. Relates to a cable modem display and method.
    Many home and business computer users typically use a modem to access the Internet through a public telephone network, using home or work telephone lines. Public telephone networks provide dedicated circuits from modems to servers located on the Internet service provider side. The server acts as a gateway to the Internet. However, the bandwidth of typical home and business telephone lines is relatively small, which limits the rate at which information can be received from the Internet. Although higher speed phone line connections are possible and many times faster than regular phone lines, these phone lines do not provide the desired data rate.
    As an alternative to telephone line use, the Internet can be connected via coaxial cables using a cable modem. Coaxial cable offers greater bandwidth than available telephone lines and is widely used by existing television subscribers. After all, the trend is toward the use of cable modems.
    Because cable modems are being adopted by a large part of the population, they can simplify the use of modems, including simplifying the means by which the status and operation of cable modems can be understood while providing all the status information desired by the user. There is a need. In addition, as many cable modems are configured to be used as external cable modems, which generally mean the outside of a computer, it is also important that the cable modem has an appearance that satisfies the user.
    Conventional cable modems sometimes use a light indication on the modem to provide information about the status and operation of the modem. However, conventional cable modem states or conditions during modem display do not provide a mix or compilation of the most useful information. In addition, current cable modem designs are generally unintuitive, difficult to understand, and provide less information in a visually less satisfying way than the user can hope for. For example, most external modems and cable modems include status indicator lights that are used to demonstrate operation, such as transmission status indicators and reception indicators, often labeled "TX" and "RX." These lights usually illuminate one color while data is being transmitted or received, and sometimes the length of the light is related to the actual transmission or reception operation. However, since only one color is used, they indicate only one information state.
    The technical problem to be solved by the present invention is to provide information that is suitable for use in connection with a general home and work computer, which is relatively inexpensive, most useful or frequently used by a user, and is easy to use and easy to read and understand. The present invention provides an apparatus and method for displaying the condition, state and operation of a cable modem that provides information on the state of the modem using an intuitive presentation that produces a satisfactory visual effect.

    1, an embodiment of a cable modem 100 connected to a general purpose computer 104 and connected to a cable head-end server (hereafter server 102) via a coaxial cable 108 is shown. The server 102 is preferably operated by an internet service provider and later linked to the internet 106. In general, Internet service providers act as point of reference (POP) and provide high speed data services. Computer 104 typically includes a bus coupled to a network controller, such as an Ethernet card, or other means for connecting to cable modem 100. Ethernet controllers are widely available from many manufacturers. The computer 104 is shown in FIG. 1 for illustrative purposes only, and devices other than the computer 104 may be coupled to the cable modem 100. The cable modem 100 may be configured as an external or internal cable modem.
    The cable modem 100 shown in FIG. 1 includes a cable modem condition-status-operation display 110, a CPU or microcontroller 114, a random access memory (RAM) 118, a read only memory (ROM). Modem chip 116, memory buffer 112, and network controller 120, which also include some processor functionality. The cable modem 100 transmits or receives digital data, or converts digital data into analog data before transmission and converts analog data into digital data after reception. The configuration of the cable modem 100 shown in FIG. 1 is provided merely as an example, and other configurations may be used.
    In a preferred embodiment, at least four status indicators 122-128 are used, preferably at least two of which may emit two or more colors of light. The four status indicators 122-128 are assigned one status indicator 122-128 for each of the following conditions: (a) reception status, (b) transmission status, (c) service status and (d) It is desirable to provide information on the call state. The status indicators 122-128 may be used on other modems, but are preferably identified on the cable modem 100, preferably accompanied by text, respectively, received, transmitted, serviced, and busy. Preferably, the reception indicator 122 and the transmission indicator 24 can be dimmed with at least two colors. In the preferred embodiment, of course, other colors may be chosen, but the two colors are green and yellow.
    The reception status indicator, hereinafter, the reception indicator 122, is used to provide information regarding the cable modem 100 connection status to the channel for data reception, and the data reception operation of the cable modem 100. When the cable modem 100 is not in operation, it may be desirable that the status display 110 is not dimmed. During modem initialization, the reception indicator 122 is preferably intermittently dimmed by a green light source to indicate that the cable modem 100 is searching for a reception channel. The flashing rate is preferably about 1 Hz with a 50% duty cycle, although other desired or actual flashing rates and duty cycles may be used. It is understood by the user that the green light blinking means that the cable modem 100 is performing a normal operation requiring a wait. When scanning is complete, the reception indicator 122 does not blink and remains dimmed by the green light source as long as the cable modem 100 is connected to the selected channel. The continuous green state of the receive indicator 122 is understood by the user easily and intuitively to mean that the cable modem 100 is connected to the receive channel and is ready to receive. When data is received, the status indicator may be used with any desired or actual color, blink rate and duty cycle, but preferably with a second color, preferably at a rate of about 1 Hz with a 50% duty cycle, preferably It will be desirable to be intermittently dimmed by yellow. In other cases, the blinking of yellow to illuminate the reception indicator 122 illuminated by the green light source is easily and intuitively understood by the user to indicate normal data reception operation.
    Transmission status indicator, hereinafter transmission indicator 124 is used to provide information regarding the initialization status of cable modem 100 and data transmission operation of cable modem 100. If the cable modem 100 is not in operation, the status display 110 may not be dimmed. During modem initialization, the transmit indicator 124 is preferably intermittently dimmed by the green light source to indicate that the cable modem 100 is ranging. The blink rate is preferably about 1 Hz for a 50% duty cycle, although other desired or actual blink rates and duty cycles may be used. Blinking green is understood by the user to be easy and intuitive that the cable modem 100 is performing a normal operation that requires a wait. The transmit indicator 124 is continuously dimmed after ranging is complete. The continuous green state of the transmit indicator 124 informs the user that the cable modem 100 is ready to send data. When data is transmitted over the coaxial cable 108, the transmit indicator 124 is preferably first flashed at a rate of about 1 Hz at 50% duty cycle, although other colors, blink rates and duty cycles may also be used. It is preferred that the color is intermittently dimmed by two colors, preferably yellow. Preferred yellow does not signal what the display of red flashing can signal. Thus, it is readily and intuitively understood by the user that the yellow blink dimming the transmission indicator 124 illuminated by the green light source in other cases indicates normal transmission operation.
    The service indicator 126 is used to indicate the status of the modem registration initialization process. During the registration process, the service indicator 126 may be used with other colors, blink rates and duty cycles, but preferably by a selected color, preferably green, flashing at a rate of about 1 Hz with a 50% duty cycle. Intermittent dimming is preferred. Blinking green is easily and intuitively understood by the user to indicate that the cable modem 100 is performing routine functions that require a short wait. The service indicator 126 will be illuminated continuously when this process is complete. This is easily and intuitively understood by the user to indicate that the cable modem 100 is ready for operation. The service indicator 126 is not dimmed unless the cable modem 100 is in operation.
    Busy indicator 128 preferably has only one red light source. This light source is not normally dimmed. When the cable modem 100 attempts to transmit data but cannot transmit data because the channel is temporarily busy, of course other colors, blink rates and duty cycles can also be used, but preferably have a duty cycle of 50%. The red light source flashes at a rate of 1 Hz. This blinking stops when transmission is restored. The blinking of red light is easily and intuitively understood by the user to indicate a problem.
    In another embodiment shown in FIG. 2, the status display 100 includes six status indicators 122-132, preferably at least three of which can emit two or more colors of light. The status indicators 122 to 132 are assigned to (a) power state, (b) reception state, (c) transmission state, (d) service state, e) it is desirable to provide information regarding call status and (f) message status. The indicators may of course also use other textual notations, but preferably are preferably identified on the cable modem 100, accompanied by the text power, receive, transmit, service, busy and message, respectively. Thus, in addition to the receive indicator 122, the transmit indicator 124, the service indicator 126, and the busy indicator 128 described above, a power indicator 130 and a message indicator 132 are provided.
    The power indicator is used to identify whether the cable modem 100 is on or off. Preferably, a light source capable of emitting two different colors of light is used in power indicator 130. The colors used are preferably red and green. When the cable modem 100 is off, the light source is not dimmed. When cable modem 100 is turned on, power indicator 130 is powered on cable modem 100 but cable modem 100 is performing a self-diagnostic routine and is not yet operational. In order to show, red flashes intermittently, preferably at a rate of about 1 Hz with a 50% duty cycle. The blinking of red light is understood by the user to be easy and intuitive that the cable modem 100 is not yet in operation, meaning that the user must wait. In other alternative embodiments, other colors, blink rates, and duty cycles may be used. When the diagnostic routine is completed, if the cable modem 100 is in operation, the power indicator 130 emits green light to indicate the operating state of the cable modem 100. The power indicator 130 remains dimmed with green light while the cable modem is operational. Green light is easily and intuitively understood by the cable modem 100 user to indicate an operational state or condition.
    The message indicator 132 signals that an e-mail message has been received and is available for download. If no message has been received, the message indicator 132 is not illuminated. If the message has been received, the message receiver 132 starts blinking. Any color, blink rate and duty cycle may be used, but the message indicator 132 is preferably illuminated by flashing green light at a rate of about 1 Hz with a 50% duty cycle.
    3 shows an embodiment of a cable modem 100 with two additional status indicators 134 and 136. The additional status indicators 134, 136 may be placed in front of the cable modem 100 or anywhere in the cable modem 100 housing. For example, FIG. 6 shows a rear view of the cable modem of FIG. 4, including a link indicator 132 and an Ethernet indicator 134. In alternative embodiments, link indicator 132 and Ethernet indicator 134 may be included in display 110. However, the user of the cable modem 100 is usually referred to by the link status indicator or the Ethernet operational status indicator until any problem is identified with reference to the marking on the front of the cable modem 100 including the six status indicators shown in FIG. You will not need the information provided. Thus, these status indicators are located on the back of the cable modem 100 housing in the embodiment shown in FIG. Known cable connector 138, display switch 142 for turning the display on the front of the cable modem on and off, known RS-232C port 144, reset button 146, Ethernet operational status indicator 148, link status Numerous shapes are shown on the back of the cable modem housing, including indicator 150, Ethernet jack 152, and known power connector 154. The shapes or the arrangement order or position of the elements are not strict in the present invention. Other configurations may be used, and shapes may be removed or added from what is shown here.
    4 to 11 generally show a perspective view of the cable modem from all sides. 4 shows a front perspective view of an embodiment of the cable modem of the present invention. In the embodiment shown in FIG. 4, the status indicators are placed under the status indicator cover 156, which is preferably made of a right angle plastic material which is desirable to prevent the status indicators 122-132 from being visible if they are not illuminated. 5 shows a front view of the cable modem of FIG. FIG. 6 shows a back view of the cable modem of FIG. 4 described above. 7 and 8 show the cable modem of FIG. 4 from both sides, and FIGS. 9 and 10 show top and bottom perspective views of the cable modem housing. FIG. 11 shows a front view of the cable modem housing of FIG. 5 with status indicators 122-132 illuminated and viewed through the rectangular status indicator cover 156.
    In general, the status indicators may be illuminated by any known light source using any desired or practical colors. However, preferred means for dimming the status indicators include the display of status indicators in a location, such as a computer screen, and the use of LEDs in status indicators placed over the housing of the cable modem 100.
    It is well known to generate the desired colors in a computer monitor or the like, and any known means for doing so may be used. It is desirable that the status indicators be relatively small so that the status indicators do not occupy a significant portion of the screen being displayed, so that the user can use most of the screen for other functions. It is well known to provide status indicators that occupy only a small portion of a computer monitor or screen, and any means for building such a display can be used.
    With regard to the use of LEDs, it is desirable to use two color LEDs for status indicators that can be illuminated by one or more colors. For example, in one embodiment of the cable modem 100 display, the receive indicator 122 and the transmit indicator 124 each include LEDs that can emit both green and red light. Simultaneous emission of green and red light results in yellow dimming. A reception indicator 122 comprising two color LEDs capable of emitting both green and red light is used as follows. During initialization while the cable modem 100 is searching for a receive channel, the LED will intermittently emit green light at the desired speed and duty cycle. When scanning is completed successfully, the LED will emit green light continuously. When data is received, the LED will intermittently emit red light at the desired frequency or blink rate in addition to the green light that is still emitting. Thus, the LED emission of red and green light results in yellow illumination of the reception indicator 122 when data is received.
    The present invention also includes a method for providing information about a condition and status of a cable modem 100 to a cable modem 100 user, the method comprising: (a) a cable modem 100 receiving channel; Causing the first status indicator to emit a first color intermittently to indicate that it is scanning (b) the first status indicator to indicate that the cable modem 100 is connected to the selected channel.
