Traffic manager, gateway signaling and provisioning service for all packetized networks with total system-wide standards for broadband applications including all legacy services
First Claim
1. In a telecommunications network of the type including a transport medium linking a plurality of nodes formed by one or more items of network equipment interconnected via virtual connections for transporting packetized data to and from network nodes in response to a signaling request, the improvement comprising:
- a provisioning manager coupled to the network for configuring the virtual connections and for monitoring the performance and operational status of the virtual connections and items of network equipment;
a signaling manager coupled to the nodes via the transport medium for setting up, modifying and tearing down virtual connections between network nodes in response to the signaling request; and
a traffic manager coupled to the signaling manager and to the provisioning manager for controlling the traffic loading of the network according to virtual connection attributes specified by the provisioning manager.

Abstract
Broadband integrated services are performed via digital, channelized or optically coded networks by a system which organizes, interfaces, provisions, loads and controls, in real time, the transport of grouped or organized information (such as packetized cell data) through interface access devices and packet switches that are compliant with domestic and international communication standards. A packet core network includes multiple packet switches and interface access devices coupled to an existing narrowband or broadband network. A signaling manager, a provisioning manager and a traffic manager perform all broadband and narrowband routing, port provisioning and connecting functions for all network devices. A set of software interface modules for each equipment vendor allows the provisioning manager, the signaling manager and the traffic manager to impose control demands and make network management decisions on a real time basis via an application protocol interface. Bit error rate caused by the disparity between low speed (such as TDM) networks and high speed (such as OCR) networks is substantially reduced by synchronizing the overall network and all switching components to a primary reference clock that has an accuracy of 1×10−11 second per month or better.

12. In a telecommunications network of the type including a transport medium linking a plurality of nodes formed by one or more items of network equipment interconnected via virtual connections for transporting packetized data to and from network nodes, the improvement comprising:
-
a plurality of external reference clocks coupled to the network, each external reference clock providing a reference clock signal as a timing input to one or more items of the network equipment for synchronizing the transfer of packetized data though the network equipment; a primary reference clock for providing a primary reference clock signal, the primary reference clock signal being coupled as a common timing input to each of the external reference clocks for synchronizing the reference clock signals with the primary reference clock signal; and wherein the external reference clocks each comprise an external Stratum 1 clock having a free-run accuracy of 1×
10−
