Abstract
A remote access system for a trader turret telephone switching network. A line status display is created at the remote site using the Internet as a data channel. A line command can be entered remotely using a “mouse” (or other graphical interface) and communicated back to the switching network via the Internet. A voice channel can then be established to the remote site via the public telephone switching network or via the Internet.
