1. A network system having STAR topology comprising:
- a hub site; and
at least one remote site;
wherein call control and management between the hub site and the remote site use Internet Protocol (IP) addressing and HDLC addressing at the link level for identification thereby allowing only a desired remote site to read data transmitted.

Abstract
A network system with a STAR topology allows single hop connectivity between sites. The system has a hub site and a plurality of remote sites. A first channel is used for sending data from the hub site to all of the plurality of remote sites. A plurality of second channels are used for transmitting data from each of the plurality of remote sites to the hub site and for transmitting data between the plurality of remote sites. In the system, call control and management between the hub site and the remote sites and between different remote sites use Internet protocol (IP) addressing for identification.

12. A network system having STAR topology and which allows on demand single hop connectivity between remote sites comprising:
-
a hub site;
a plurality of remote sites;
a first channel for sending data from the hub site to all of the plurality of remote sites;
a plurality of second channels for transmitting data from each of the plurality of remote sites to the hub site and for transmitting data between the plurality of remote sites;

15. A method for allowing a network system having STAR topology to perform on demand single hop connectivity between remote sites comprising the steps of:
-
providing a single hop server at a hub site of the network system;
providing a first remote modem at each remote site for continuously receiving data from the hub site and for transmitting data when required;
providing a second remote modem at each remote site that receives data from a second remote site for receiving data sent from a different remote site;
configuring the network so call control and management between the hub site and the remote sites and between different remote sites use Internet Protocol (IP) addressing for identification; and
configuring a direct channel between remote sites that are communicating to transmit the data.
