Abstract
The instant invention allows control of voice transmission from end user to end user by common channel signaling without the repeated conversion delays encountered by entering and exiting the standard voice network and an ATM network. The control is accomplished in parallel over the standard public switch telephone network while the voice “data” is transported over an ATM “data” network. Each ATM node has with it a co-located PSTN voice switch. A pair of control links are used to communicate between the two co-located ATM and TDM switches.
