## Title
Media terminal adapter (MTA) initialization process display by use of an embedded caller name and caller identification

## Abstract

Systems and methods are disclosed for a media terminal adapter (MTA) that gathers and reports steps of an initialization process as well as other information. The MTA tracks each completed step via a state machine and subsequently converts the steps and other information into an FSK format. FSK data is then provided to either a Type 1 or Type II caller identification telephone, or other caller identification box that includes a caller identification display, or a coupled handheld display device. Additionally, the MTA may also convert the completed steps into an audio wave file that is then transmitted to a connected telephone or an internal speaker.

## Background
FIELD OF THE INVENTION
This invention relates in general to telephony systems over broadband, more specifically broadband over coaxial cable, and more particularly, to the field of enabling a media terminal adapter initialization process display by use of an embedded caller name and caller identification.
DESCRIPTION OF THE RELATED ART
Broadband communications systems, such as satellite and cable television systems, are now capable of providing many services in addition to broadcast audio/video signals over their existing systems. Some advanced services in a broadband communications system along with providing conventional cable television signals are telephony services, such as high-speed data and telephone. To support these services, cable modems and media terminal adapters are used in the subscriber's premises and have typically been coupled to coaxial cable in a communications network (CN). U.S. Pat. No. 6,161,011 to Loveless, the disclosure and teachings of which are incorporated herein by reference, shows an example of a hybrid fiber/coaxial (HFC) communications network that could be used to implement the present invention.
FIG. 1 is a block diagram of a communications system that is suitable for transmitting voice and data signals in a cable communications system. A technician or a customer installs a media terminal adapter (MTA) 110 at a customer's premises and then initializes the MTA with a central office 120 over a communications network 123, where the communications network may comprise fiber optical cable and coaxial cable as opposed to a traditional public switched telephone network (PSTN). The MTA 110 performs several steps during the initialization process. At any time, the MTA 110 may fail during initialization with a cable modem termination system (CMTS) 115 that is located in the central office 120. If a customer has a connected computer 125, a web page associated with the initialization process and the MTA 110 may be viewed to determine what state in the initialization process the MTA 110 is currently and where in the initialization process the MTA 110 may have failed. However, many times a customer is not connecting a computer but rather just connecting a telephone 130. In this case, the technician or customer is unable to determine the point of failure in the initialization process and therefore effectively troubleshoot initialization of the MTA 110.
Thus, there exists a need for a remote method and system to determine the progress of the MTA's initialization and the point of failure, if a failure occurs, without requiring a computer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Preferred embodiments of the invention can be understood in the context of a broadband communications system. Note, however, that the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. All examples given herein, therefore, are intended to be non-limiting and are provided in order to help clarify the description of the invention.
The present invention is directed towards enabling a media terminal adapter (MTA) to report steps of an initialization process between the MTA and a CMTS as well as other information. More specifically, the MTA generates all or various steps of the initialization process or other information, such as the firmware and/or software version, and then transmits the information to a display on a connected telephone. A Type 1 or Type II caller identification telephone, or other caller identification box, which includes a display for caller identification name and number, is then used to receive and display the information. A handheld receiver is another option for displaying information generated by the MTA or information received from the CMTS, if a Type 1 or Type II caller identification telephone or other caller identification box is not available. The handheld receiver may be physically connected to the MTA through a connector or by using infrared (IR) technology. Furthermore, the MTA may also generate audio steps of the information that can then be audibly heard by a technician or a customer by either a connected telephone or a speaker included in the MTA.
FIG. 2 is a block diagram of a communications system 200 including an MTA 205 that is coupled to a Type 1 or Type II caller identification telephone 210, or caller identification box, that is suitable for use in implementing the present invention. The telephone 210 includes a display 215, which can either be part of the telephone or a separate display, that is traditionally used for displaying caller identification information, date and time information, or any received caller messages. In accordance with the present invention, the display 215 via the telephone 210 also is capable of receiving and displaying information from the MTA 205. Information may include steps of the initialization process such as passed, failed due to a stated reason, or passed with errors, for example. Additional information may be the firmware and/or software load versions of the MTA 205. It will be appreciated that the information is configurable and can include messages from just key steps of the process to every step of the process along with other programmable information or data coming from either the MTA itself or from the CMTS.
FIG. 3 is a block diagram of the MTA that is suitable for use in the system of FIG. 2. A coaxial F connector 310 connects the MTA 205 to the communications network 123. A tuner 315 then receives and filters data intended for the MTA 205 and routes the data to a processor 320. If the data is intended for a coupled computer, the processor 320 routes the data to either an Ethernet connector 335 or a USB connector 340 depending upon the application. If the data is telephony data, the data is routed to a telephony digital signal processor (DSP) 345 for further processing, such as code decoding, packetization, echo cancellation, or other telephone signal processing. The telephony data is then routed to a connected telephone 210 via a subscriber line interface chip (SLIC) 350. The telephone 210 is typically connected to the MTA 205 with CAT-3 or CAT-5 wiring and an RJ11 telephone jack 355. The MTA 205 also includes a power supply 360 for powering the telephony DSP 345 and the SLICs 350 as well as memory 325, such as SDRAM and Flash memory, for system storage purposes.
In accordance with the present invention, the MTA 205 also includes a state machine 365 coupled to the processor 320 for tracking steps completed in the initialization process. A frequency shift keying (FSK) converter 370 converts the data received from the state machine and other information that may be generated by the MTA 205 or received from the CMTS 115 into ones and zeros that can be provided to the telephone 210, where FSK data is then interpreted and displayed in a readable format. Additionally, during the initialization process, the processor 320 activates the SLIC 350, which is the connection point between the MTA 205 and the telephone 210, during the initialization process. Conventionally, the SLIC 350 is inactive until such time as the initialization process is complete and communications have been established between the MTA 205 and the CMTS 115.
FIG. 4 is a block diagram of an MTA 400, which is a modified MTA 205 of FIG. 3, in accordance with the present invention. The MTA 205 of FIG. 3 may also include a wave file generator 405 that accommodates data generated by the state machine 365. More specifically, depending upon the steps completed as noted by the state machine 365 or other received information, a wave file generator 405 generates an embedded audio file using an audio format (e.g., .wav, .mp3, etc.) that may be transmitted to a speaker 410 included in the MTA 400. Alternatively, the audio file can be provided to the telephone 210 for hearing through the handset. In this manner, the wave file generator 405 can be used in conjunction with or as an alternative to the display on a caller identification telephone or box. Additionally, an IR transceiver 415 may also be coupled to the processor 320 for communicating IR signals that correspond to the initialization. The IR signals can then be transmitted to or received from an IR handheld device 420 for display.
In a first implementation of the present invention, information can be displayed on the telephone 210 by enabling the function via a management information base (MIB) object. More specifically, in accordance with the present invention, certain events are included in a MIB table, which is stored in memory 325, that correspond to the initialization process and other information. When the processor 320 receives a response from a state machine 365 indicating that a step is complete, the processor 320 retrieves a corresponding MIB from memory 325 and converts the step into an FSK format via an FSK device 370. FSK data is then provided to the display 215 via the telephony DSP 345 and the SLIC(s) 350. Additionally, when the processor 320 receives information about the firmware version, for example, the information is provided to the FSK device 370 for conversion and then to the telephone 210 for display.
In a second implementation, a specific digit string corresponding to the initialization steps is stored in a digit map. A technician or customer can then determine which step has been completed at any time throughout the initialization process by picking up a telephone handset, dialing the specific digit string, and hanging up the telephone handset. Once the handset is hung up, the processor 320 accesses the last completed step from the state machine 365, converts the step into FSK data, and then provides the information to the display 215. Furthermore, in a third implementation, the specific digit string can be used with the handset off the hook. Similar to the above embodiment, the handset is removed from the hook and the digit string is entered. The data is then retrieved from the state machine 365 and provided to the display 215 even while the handset remains off-hook.
It will be appreciated that each of the methods may be used singly or in conjunction with one another. For example, there may be a MIB associated with each reporting selection: 1) a first MIB to enable the display of the initialization process via the caller identification mechanism and uses FSK data to display on the telephone display; 2) a second MIB to enable the audio annunciation of the initialization process via an audio file that is heard from either the telephone 210 or from the MTA 205; 3) a third MIB to enable the transmission of the initialization process to the handheld transmitter/receiver 420; and 4) a fourth MIB to set the digit string used for starting and/or stopping the initialization process reporting. As mentioned, the reporting may include all, some, none of the steps, or other displayable information.
Accordingly, systems and methods have been provided that enables an MTA to gather and report information to a connected telephone display, an IR or wired handheld display device, or a speaker It will be appreciated that further embodiments are envisioned that implement the invention, for example, using all software or adding modes for additional features and services.
