Abstract
A method for having a modem use the call waiting feature by placing the data connection on hold while the user uses the telephone is invented. A device which can detect the call waiting signal and upon detection display a message on the user's monitor that there is an incoming call waiting for him\her to answer is invented. A "Line Monitor" will be placed between the incoming telephone line and the modem. When there is a data connection, and a person attempts to contact the modem user by telephone, the device will intercept the call waiting signal and place a message on the users screen.
If the user decides to answer the incoming call, the user will then type a command and both modems are placed on hold for a predetermined amount of time. Then the user can pick up the telephone and respond to the call. When the user is finished with the telephone call he\she will then hang up and another command is entered to re-establish the modem connection.
If the user decides to answer the incoming call, the user will then type a command and both modems are placed on hold for a predetermined amount of time. Then the user can pick up the telephone and respond to the call. When the user is finished with the telephone call he\she will then hang up and another command is entered to re-establish the modem connection.

Specifications The followi~ a st~n(l~rd ~ waiting procednre (voice).
User-l is connected to user-2(Fig.l). When user-3 tries to connect with user-l, a switching machine recognizes that user-l is already connected to another user(Fig.2). In this case the switching m~chin~ will send user-l a signal informing him that another user is trying to contact him. User- 1 can then:
1. Accept the interrupting call by ~ign~ling back. Then the connection between user-l and user-2 is disconnected temporarily. User-l and user-3 are then connected (Fig.3). When user-l and user-3 finish the conversation, user-l will signal the switching machine, telling it that he is done. Then the switching machine will reconnect user-l with user-2 (Fig.4).

Th~ followi~ th~ st~n(l~rd mndem connection.
User-A connects with user-B. A continuation signal is tr:3n~mitted back and forth be-tween the two modems conril",il~g that the other carrier is there. When the continuation code is not sent by the modem of user-A then the modem of user-B hangs up. The h~n(l~h~k~ code must be sent back and forth continuously.
The following is the st~n(l~rd ~ll-w~itir~ proce~llre (modem).
User-A is connected to user-B (Fig.S). When user-3 tries to connect with user-A, the switching machine recognizes that user-A is already connected to another user (Fig.6). When the switching machine sends the signal, the modem automatically accepts the call, which then disconnects the two modems temporarily. The continuation carrier that is supposed to go back and forth is not sent anymore and user-A and user-B are completely disconnected. Then user-A's telephone (voice) begins to ring. When user-A picks up the telephone, he is connected to user-3 (Fig.7).
If user-A adjusts his initi~li7~tion string (by typing *70, after "ATDT"), all inlellupling calls are autom~tic~lly rejected by the co-l-pu~elized switching m~chin-o.

User-A is connected to user-B (Fig. 8). The h~n(l~h~ke code is being sent back and forth now.
The "Line Monitor" (LM) is monitoring the data being transferred back and forth on the line.
User-3 tries to connect to user-A (Fig.9). The switching m~chin~ will then send a signal to user-A not knowing whether there is a modem or a telephone there. User-A's "Monitoring De-vice" should translate this signal into a message to be displayed on the screen of the computer connected to the modem, informing the user there is an incoming call.
User A can then:
a) type a command which tells the modem to send a different code than the original code sent back and forth. This code will tell user-B's modem not to send a h~ndsh~ke code or to expect a h~ml~h~ke (but receive one if one comes in) for a while. It will also tell user-A's modem not to send and NOT to receive a h~nd~h~k~, code. While the two modems are on hold, user-A can pick up his telephone and talk to user-3 (Fig. 10). When he is done user-A can then type an-other command that will tell the modem to send the continuation code to user-B. User-B's mo-dem will then receive the continuation code and User-A and user-B are reconnected (Fig. 11).
b) type a command which tells the device to ignore this incoming call.
Th~, follow;r~g nt-,eds to be don~, to perform thi~ k A device that can translate the signal into a message on the screen must be designed.
A command must be created that will activate and disable sending the second h~nd~h~ke code.
A user need~ to do the following to ll~e thi~ filnction The device that can translate the call-waiting signal into a message on the screen must be avail-able.
The user's software must be updated to be able to use the command to activate the "hold"
mode.
~138565 Components of the "Line Monitor"
The T in~ Monitol h~ 4 rn~in con~onPnts:
Filter- allows all data to pass directly to the modem except the call-waiting signal Translator- takes the call-waiting signal from the filter and sends a digital message to the com-biner Combiner- combines the digital message from the translator with the data going to the modem Switch- switches the line between the modem and the telephone Feeder- sends the continuation code to the modem to which it is connected to ensure continu-ity The telephone line comes from the wall jack to the Line Monitor, and from the Line Monitor to the modem. A telephone must be plugged into the Line Monitor.
While the user is on-line with the modem, the Line Monitor monitors the data flowing on the telephone line. When it detects a call-waiting signal it inlelcep~ it then feeds it to the transla-tor. The translator then translates the signal to a digital message and then sends the digital mes-sage to the combiner. The combiner interleaves the message with the data flowing on the tele-phone line. The user will then receive a message on her monitor stating there is an incoming call-waiting for her to answer. Also prompting the user to push "Y" if the user wants to receive the message, or "N" if the user does not want to receive the message. If the user types "N", the Line Monitor will ignore the incoming call-waiting signal. If the user types "Y" the modem will send a signal to the other modem (that has another Line Monitor) telling it to "Please Wait".
The filter at the other end will receive this signal (see note below) and tell the feeder to send the continuation code to the modem it is connected to. The first user's Line monitor will then send the continuation code to itself, then the switch will then connect the telephone. Now the two modems believe they are still connected to each other, and the user's telephone will then ring and he\she can the pick up the telephone and speak with the caller.
When he\she is finished with the call, he\she can then hang up the telephone. The Line Monitor will then do the following:
- switch the line from the telephone to the modem - send a signal to the other user's Line Monitor telling it to stop sending the continua-tion code to itself - stop sending the contin~1~tion code to itself - send the continuation code over the line to the other modem Both modems are now back on-line.
5 ~ 5 NOTE:
There maybe different ways of assuring continuation. These should be investigated.
Regardless of the continuation code, we suggest the following control method:
The "Line Monitor" should have a circuit which detects the "Please Wait" signal and produces a local continuation signal of the same format used during the usual communication between the two modems.This is necessary to insure that the party which is asked to wait can be put on hold until the modem to modem communication is resumed.
