1. A telecommunications network, comprising:

  • a plurality of central office switching systems coupled by local links to customer terminals;

    trunks interconnectiion the central office switching systems, for carrying communications switched to and from the local links via the central office switching systems;

    an interoffice signaling network comprising a signaling transfer point for carrying call set-up related signaling messages in a first protocol between the central office switching systems; and

    an interface coupled to the signaling transfer point of the interoffice signaling network and for coupling to an open-access, non-proprietary internetwork connecting spaced dissimilar networks and using transmission control protocol/internet protocol (TCP/IP) to link the dissimilar networks;

    wherein the interface performs two-way protocol conversions between the first protocol and TCP/IP to enable communication of call set-up related signaling messages for the telecommunications network over the internetwork.
