1. A telecommunications system for updating and synchronizing data between a master intelligent node and at least one standby intelligent node, said telecommunications system comprising:

  • bulk transfer means within said master and standby intelligent nodes for transferring data stored within a master memory within said master node to a standby memory within said standby intelligent node, said bulk transfer means transferring substantially contiguous, configurable-sized portions of said data;

    a master index manager within said master intelligent node for allocating an index associated with the location of a stored data element in said master memory, said index being a master starting memory address within said master memory of a given one of said configurable-sized portions of said data;

    a master data transfer function within said master intelligent node for receiving said index from said index manager and said data element;

    a buffer within said master intelligent node for storing said given configurable-sized portion of said data, beginning with said stored data element;

    a standby data transfer function on said standby intelligent node, said buffer being forwarded to said standby data transfer function, said given configurable-sized portion of said data being copied into said standby memory by said standby bulk transfer means starting at the location in said standby memory associated with a standby starting memory address; and

    a standby index manager within said standby intelligent node, said standby bulk transfer means receiving said standby starting memory address from said standby index manager.
