Line conditioner and build-out for telephone systems

A method of making a transmission line conditioner device for installation on a voice-band transmission medium comprising the steps of:

• creating two component groups, each having in parallel an inductor and a capacitor wherein the component groups are each positioned in series with a respective input connection and a respective output connection;
• and
• encasing the component groups in a package so that the respective input connections and respective output connections are conductively accessible from outside of the package to create a transmission line conditioner device.

A method of conditioning a voice-band transmission medium comprising the steps of:

• placing a first end of a component group having two ends in conductive contact with a first conductor of the transmission medium, wherein the component group comprises an inductor and a capacitor connected in series circuit formation with respect to one another;
• and
• placing a second end of the component group in conductive contact with a second conductor of the transmission medium which is in parallel circuit formation to the first conductor, whereby the component group is connected across the parallel conductors, and whereby the transmission medium is conditioned to permit the transmission of high-quality voice-band signals and high-frequency digital signals.

A method of making an improved transmission line build-out device for installation on a voice-band transmission medium comprising the steps of:

• creating a component group having an inductor and a capacitor connected in series circuit formation with respect to each other, wherein the component group is conductively connected at one end to a first lead line having an input connection and an output connection and conductively connected at a second end to a second lead line in parallel circuit formation with the first lead line, the second lead line having an input connection and an output connection;
• and
• encasing the component group in a package so that the respective input connections and respective output connections of the first and second lead lines are conductively accessible from outside of the package to create an improved transmission line build-out device.
