Abstract
A method and apparatus for the non-disruptive addition of one or more nodes to an active inter-nodal network is provided. A telecommunications switching system includes a plurality of nodes interconnected by an inter-nodal network which carries packetized information among the nodes. A host which issues various control instructions is connected to at least one node in the system. When one or more new nodes are to be added to the system, the two nodes adjacent to the location selected for the new node are instructed to begin a synchronized routine for simultaneously beginning to temporarily operate in a special loop back mode of operation which allows telecommunications traffic to continue to travel on the inter-nodal network while the new node or nodes are being physically connected into the system. Thereafter, a sequence of instructions provides for a synchronized routine for both neighbor nodes to return to open operating mode from loopback mode simultaneously. The instruction sequences are issued by a host and a master node of the system for implementing the non-disruptive addition of the new node or nodes to the system.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
