Abstract
A METHOD FOR COLLECTING CALLING NUMBER IDENTIFICATION
DATA (CNID) INTO A PERSONAL COMPUTER WITHOUT THE
NECESSITY OF MAINTAINING THE PC IN A POWERED STATE
ABSTRACT
A method for collecting information from a telephone line and passing the collected information to a computer when the computer is in a powered up state. The informa-tion is either present between ringing signals or any dialing tones sent after the telephone is taken off-hook.
The method requires that the ringing of the telephone or the off-hook of the telephone be detected. After one of these is detected, the information from the telephone line is demodulated. Next, the state of the computer must be determined. If the computer is powered down or the required software is not operational, the informa-tion retrieved from the telephone line is stored. The computer is continually checked for a powered up and operational conditional. When the PC is operating, the information is then transferred to the computer.

2~37~ 6 A METHOD FOR COLLECTING CALLING NUMBER IDENTIFICATION
DATA (CNID) INTO A PERSONAL COMPUTER WITHOUT THE
NECESSITY OF MAINTAINING THE PC IN A POWERED STATE
CROSS-REFERENCE TO REL~TED APPLICATIO~S
The present application is related to the following co-pending U.S. patent application beiny assigned to the same assignee, entitled:
"AN APPARATUS TO COLLECT CALLING NUMBER IDENTIFICA-TION DATA (CNID) INTO A PERSONAL COMPUTER WITHOUT THE
NECESSIT~ OF MAINTAINING THE PC IN A POWERED STATE", "(Attorney Docket No. 92-1-304)".
FIELD OF THE INVENTION
The present invention relates to a PC accessory card and to customer premises telephone call management product. More particularly, to the instructions executed by an accessory card that receives Caller Identification (CID) data for incoming calls and DTME data for outgoing calls. The hard~Jare consists of an accessory card, which includes a microprocessor and an external wall-plug power supply. The accessory card attaches to a standard tele-phone line with CID service via an RJ-11 type connector.
CID data is collected for further processing by the accessory card.
BACKG~OUND OF THE INVENTION
CID data is sent from a telephone company central office over a standard telephone line to the subscriber.
This data is sent as a burst of Bell 202 1200 baud asynchronous data between the first and second occurrence of ringing voltage. The most common CID device marketed to subscribers is a free-standing LED or LCD display unit. This unit provides a display of the data and perhaps a limited storage of incoming call data. How-ever, these units provide no means to export the data.
A CID device that attaches between the CID telephone line and a PC's serial or parallel port is also currently , , . .
. .
2 ~
available. This device demodulates the CID Bell 202 data and sends it into the PC for further processing. How-ever, this device does not collect and store information while the PC is turned off. Incoming call data, i.e.
calling number and time of call, can be used in a number of ways by the PC user.
Prior to the present invention, PC-based computer CID data collection while the PC is powered down was not supported. The user of a CID-to-PC interEace device was required to leave the host PC constantly turned on to have around the clock call data collection. However, it is undesirable to leave a PC operating when unattended due to energy consumption and wear and tear on electro-mechanical parts such as hard disk drives, as well as, insurance policies that may prohibit operation of major office equipment when unattended. It follows, that there was no means to upload that information to the PC when the PC was powered up and display that information in a graphical, user friendly manner.
Therefore it is the objective of the present inven-tion to provide a method of collecting CNID data for in-coming calls and DTMF data for outgoing calls and trans-fer the data to a computer. The CNID method must collect CNID data even when the computer to which the device is attached, is turned off.
SUMMARY OF THE INVENTION
In order to accomplish the object of the present invention there is provided a method for collecting information from a telephone line and passing the col-lected information to a computer when the computer is ina powered up state. The information is either present between ringing signals or any dialing tones sent after the telephone is taken off-hook. The method requires that the ringing of the telephone or the off-hook of the telephone be detected. After one of these is detected, the information from the telephone line is demodulated.
Next, the state of the computer must be determined. If the computer is powered down or the required software is ' "' ` " ' .~, .
not operational, the information retrieved from the telephone line is stored. The computer is continually checked for a powered up and operational conditional.
When the PC is operating, the information is then trans-ferred to the computer.
A line interface detects ringing, an off-hook condi-tion, and receives the information from the telephone line. If the computer is turned off, the information is temporarily stored in a local memory. A sequence of in-structions is also stored in the memory. Connected tothe memory and the line interface means is a micro-processor. Under direction of the sequence of instruc-tions, the microprocessor receives the information from the line interface and stores it in the memory if the computer is in a powered down state. When the computer is in a powered up state, the information is transferred from the microprocessor to the computer through a com-puter interface. If any information was stored in the memory, the microprocessor retrieves that information from the memory before sending it to the computer. Power partitioning supplies independent power to the line interface, the memory and the microprocessor, thereby allowing them to operate while the computer is turned off. The computer interface receives its power from the computer.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention is part of a hardware and software package that comprises a complete single-line call management system. The hardware consists of a PC
card that is designed for personal computers. As shown in FIG. 1, the present invention uses a power and hard-ware partitioning scheme. The general environment is a personal computer with monitor, keyboard, and mouse 101, the card 102, and standard telephone line with CNID
service 103. Extension telephones (not shown) are moni-tored for outgoing call Dual Tone Multi-Frequency (DTMF) (tone dialing) activity and on-hook/off-hook status. It is important to emphasize that the power to most of the internal card circuitry is not sourced from the PC's main power supply, but rather from a plug-in power supply 105.
The plug-in power supply 105 is a low cost transformer-rectifier-capacitor unregulated DC power supply.
The present invention differs from existing CNID
devices in that it provides a method for collecting incoming and outgoing call data (Call Logging) even when the PC is not turned on. This feature is called Sleeping Call Collection (trademark of AG Communication Systems Corporation). The unique means of powering the card with external power also enables other card call management software features to operate independently of whether the PC is "on" at the moment.
Referring to EIG. 2, the interfaces to the card con-sist of an external power pin jack 201, telephone line RJ-11 connection 202, and the card edge connector 203.
Externally sourced power is locally regulated to 5V on the card and a well defined power-on-reset signal is generated to reset the card's own microprocessor at initial power--up 204. DC isolation and lightning/power cross protectlon are provided for the telephone line 205.
The portion o* the card's circuitry that deals with .. . .
. . , . ~
: ~ .
- 2V9762~
interfacing to the PC 206 receives 5V power (VCC-PC) ~rom the PC and is not powered when the PC is off. For the balance of the card's circuitry, a user option is pro-vided with jumpers that can be configured to power the card exclusively from the PC 207, receiving PC 5V power for all circuitry and using the PC's power-on-reset 208.
This ~umper setting does not enable Sleeping Call Collection.
The analog portion of the card 209 contains an FSK
demodulator to decode incoming CNID signals, an off/on hook sensing circuit to determine telephone line status, and a DTMF generator and decode;r. The digital portion of the card 210 contains the microprocessor, ROM, and RAM.
Additional detail on the power scheme can be had by referring to co-application: "AN APPARATUS TO COLLECT
CALLING NUMBER IDENTIFICATION DATA (CNID) INTO A PERSONAL
COMPUTER WITHOUT THE NECESSITY OF MAINTAINING THE PC IN A
POWERED STATE", "(Attorney Docket No. 92-1-304)".
Assuming that the power and reset jumpers are set for Sleeping Call Collection, the card is installed in the PC. The external wall-plug power supply is attached to the card and plugged into an AC receptacle. Finally, the CNID-equipped telephone line is attached to the appropriate RJ-ll connector. The card is ready for the initial installation of the software. With the PC booted up and operating, the installation routine is executed and some of the software is downloaded into RAM 210. Now the card is ready to receive CNID data for incoming calls as well as DTMF data for outgoing calls from the attached telephone or any extension. While the card is powered from the external wall-plug power supply, it executes its internally stored program, thereby allowing the card to continue to receive CNID and DTMF data collection of out-going calls even when the PC is not powered.
When the PC is powered-up additional software is executed by the PC. Once the PC starts executing this software, any incoming call results in a "pop-up" window;
if CNID data is present, the pop-up window displays the telephone number of the originating telephone. In the , .
2 ~ 9 ~ G 2 ~
case when the Pc is not turned on, a Quiet Call counter indicator is created. When the PC is s-ubsequently turned on, the number of calls received is displayed. By open-ing a window, the user can get details about calls re-ceived during the powered down time.
Referring to Fig. 3, a flow chart showing the logi-cal execution of the software executed by the accessory card's microprocessor is shown. As an overview, the accessory card's software continually checks to see if its call information storage buffer contains any informa-tion or if an incoming or outgoing call is beginning.
Once either of these is detected, the accessory card determines if the PC is powered up and the appropriate software is running. If the PC is operating, thèn the call information is uploaded to it. If the PC is not operating, the call information is stored in the acces-sory card's buffer. The microprocessor then continually checks for an incoming call, outgoing call~ or the PC
reaching its operating state.
If the PC and related software are switched on while the accessory card based buffer contains information to upload to the PC, then that information will immediately begin to be passed from the accessory card's buffer to the PC. The number of stored calls that have been uploaded will be shown on the associated user interface on the PC screen. The number of unanswered calls will be shown in the Quiet Call Counter indicator in the user interface. The Quiet Call Counter indicates to the user, without pulling up the main associated user interface, whether any incoming calls occurred which were not an-swered since the the main associated user interface was last invoked. This allows the user to simply glance at the PC screen after an absence from the associated phone to tell how many calls, if any, were received while he/
she was out.
With that overview and still referring to FIG. 3, three possible loops are evident. The first loop, BOX
301 to BOX 301, is the idle state. This loop is executed whenever there are no incoming or outgoing calls or call ~ U ~3 r7 ~ ~ 6 information stored in the buffer. If calling information is received and the Pc is not operating, the second loop, BOX 301, 302, 304 and 305, is executed. Once any calling information is received and the PC was not operating, the mieroproeessor eontinually executes BOX 301, 302, and 30 as its idle loop. If, however, the PC is on and the re-lated PC based software is operational, an alternate loop BOX 301, 302 and 303, is executed.
In summary, the present invention uses a powering scheme and circuit partitioning to enable a PC card to perform data colleetion and eal:l management funetions independently of the on/off status of the host PC. A
microproeessor on the PC eard exeeutes a set of instrue-tions allowing it to collect and store any call informa-tion. The microprocessor transfers the information tothe PC once the mieroproeessor determines that the PC and its software are operating.
Although the preferred embodiment of the invention has been illustrated, and that form deseribed, it is readily apparent to those skilled in the art that various modifieations may be made therein without departing from the spirit of the invention or from the scope of the appended elaims.
