Voice bridge for relay center

A voice bridge for a relay center, the voice bridge comprising:

• (a) a first telephone line;
• (b) a modem capable of receiving and transmitting data signals over the first telephone line;
• (c) a terminal having a keyboard and a display, the terminal converting the data signals received by the modem into readable characters and projecting the characters upon the display, and the terminal transmitting data signals that are entered upon the keyboard through the modem;
• (d) a telephone that connects with a second telephone line, the telephone being positioned in such proximity to the keyboard and the display that an operator may read the characters exhibited on the display and voice any message formed by the characters into the telephone and the operator may transcribe any vocal message received on the telephone into the keyboard;
• (e) means for detecting data signals on the first telephone line to discriminate voice signals from data signals on the first telephone line;
• (f) first means responsive to the detecting means for switching the first telephone line from a first mode not connected to the second telephone line to a second mode connection with the second telephone line so that in the second mode voice signals are passed through the first and second telephone lines;
• and
• (g) second means for switching, the second means for switching disconnecting the telephone from the second telephone line when the voice signals of a sufficient pre-selected level are transferred between the first and second telephone lines.

• (e) a detector connected to the first telephone line detecting data signals on the first telephone line and discriminating voice signals from data signals on the first telephone line;
• and
• (f) a switch connected and operated by the detector to switch the first telephone from a first mode not connected with the second telephone line to a second mode connected with the second telephone line so that in the second mode voice signals from the second telephone line are passed to the first telephone line.

• and
• (g) a second switch connected to disconnect the telephone from the second line when voice signals of a sufficient level are transferred from the first telephone line to the second telephone line.

A method of forming a voice bridge in a relay center, the method comprising the steps of:

• (a) receiving data signals over a first telephone line;
• (b) converting the data signals into readable characters and projecting the characters upon a display;
• (c) reading and voicing any messages formed by the characters into a telephone that connects with a second telephone line;
• (d) detecting data signals received over the first telephone line to discriminate between voice signals and data signals on the first telephone line;
• and
• (e) switching the first telephone line from a mode that receives data signals and does not pass the data signals to the second telephone line to a mode where voice signals on the first telephone line are connected to the second telephone line when voice signals are being received on the first telephone line.

• (f) detecting the level of voice signals on the first telephone line;
• and
• (g) disconnecting the telephone from the second telephone line when the voice signals of the first telephone line are of a sufficient pre-selected level.
