Abstract
A system and method for moving voice telephone calls through a data network. More particularly, the system and method are directed to the efficient operation of a novel port card for installation in present and future versions of data switches. Together port cards and data switches form nodes. The port card receives and transmits out signals through respective ports connected to links between nodes. The method provides for voice data to be switched in a Ds0 switching matrix, which is resident on the port card.
