COMMUNICATION SYSTEM
 2N - NETSTAR is a communication system that integrates
well-proven ISDN technologies with advanced GSM and VoIP
communication networks.
 The implementation capacities of the 2N - NETSTAR system
cover a wide range of customer applications for
interconnection of communication channels into a single
converged network, including transition from the ISDN to
multiple provider‘s GSM networks via ISDN and VoIP
interconnections to three-way interconnection of ISDN, GSM
and VoIP networks with a capacity that is sufficient for large
corporations.
 The transition between networks is based on a powerful
dynamic Least Cost Router (LCR), which automatically
chooses the most efficient route to the required destinations .
