ABSTRACT:

BACKGROUND THE INVENTION
A line telephone stations, often referred to as “trader turrets”, are widely used in financial trading networks such as between banks, brokerage houses, and other types of financial institutions. Telephones of this type provide access to a large number of telephone lines, typically a hundred or more. A line is selected by depressing a single key. A trading room can include many telephone key stations so that many transactions can be completed simultaneously.
Each key telephone station in a trading room has voice channel access to other stations in the trading room and to a large number of outside lines of different types (public, private, four wire etc.) Normally each outside line is available at several stations so that any one of several traders can pickup an incoming call. A status indication is provided for each voice channel at each station where the line is available to indicate ringing, busy, hold, idle, conference, etc. The status line indications are supplied through a separate data channel for all the lines available at a station. This status information is invaluable to the operator since it provides an overall picture of the trading activity. A major obstacle to providing remote turret interconnections to a trading room, however, is the difficulty in providing the necessary data channel information of line status to the remote location.
SUMMARY OF THE INVENTION
The system according to the invention provides both a voice channel and a data channel to a remote trader turret via public networks. The voice channel is preferably established using the public telephone network. The data channel is established via the Internet. The World Wide Web (WWW) is used to supply graphical information via the Internet to provide a line status display at the remote site. The channels on these two public networks are coordinated to provide remote access to the trading room switching network. With this arrangement a trader can engage in trading activities from a home office or while traveling.
Alternatively, the Internet can be used to provide a voice channel so that the Internet provides both the data channel and the voice channel.
To set up the system, the remote operator contacts the office web site by giving the necessary passwords and by then identifying the remote site for the Internet connection and the telephone number of the remote location. The office equipment supplies a screen display via the Internet giving the status of all the lines accessible to the particular trader. When the remote operator wishes to take an incoming call shown to be ringing on the remote screen, the remote operator uses a mouse to “click” on the ringing screen indication. The office system connects to the calling party and then dials the remote trader via the public telephone system to connect the parties. A similar procedure is used for placing a call from the remote location. The remote operator “clicks” on the display indication for the desired party. The office system calls the remote party on the public telephone system and then connects to the party being called.
The remote operator can use a personal computer with a high speed modem for connection to the Internet plus an ordinary telephone connection. For mobility, a laptop type computer could be used and the modem could be connected via a cellular telephone network. The remote access according to this invention does not match the speed or flexibility of the trader turret system at the office, but does provide the much needed access to the system when working at home or while traveling.
