  • High capacity advanced 8YY mass calling event network architecture
    Patent number: 7609823
    Abstract: A telephone network voting system is configured to process a large number of calls. The system receives telephone ballots cast by voters by dialing an 8YY telephone number. The telephone ballots are received by network edge switch (NES) from a local exchange carrier (LEC), and sequentially received calls are routed to a repeating sequence of segmentation databases (SDs). The SDs are configured for routing calls in a sequentially received series of 8YY calls to a repeating sequence of said NCPs. Switches are mapped to NCPs to minimize congestion on A and AA links. Call announcements are stored in disk cache.
