Abstract:
A telecommunications system for a telecommunications network including a plurality of carriers connected to a plurality of subscriber telecommunications devices and apparatus for determining carrier preference and automatically scheduling, each of said devices including means for establishing and using network system parameter information and means for identifying in-coming transmission sources; connected to each of the carriers, central means for controlling network system parameters, for receiving periodically changing out-going transmission rate data from each of said carriers, for determining which of the plurality of devices is affected by changing network system parameter information, for establishing contact silently with system parameter change affected devices through said means for identifying in-coming transmission sources, and for downloading to the means for establishing and using network system parameter information of a currently contacted device at least changes in system parameter information affecting the currently contacted affected device; and an out-going transmission rate database means for determining carrier preference when placing an out-going transmission and automatically scheduling least-cost routing among the plurality of carriers, wherein said system parameter information includes current and future out-going transmission rate data, the system comprising:each of said devices having a system clock and said central means including means for synchronizing said system clock to network clock most current network system parameters and said periodically changing out-going transmission rate data from each of said carriers.
