摘要： Aspects of the present disclosure involve systems and methods for providing routing of a communication received at a telecommunications network based on a unique identifier. In particular, a telecommunications network may route one or more communications based on a dynamically updated trunk group identifier associated with an egress user. Thus, in addition to routing the communication based on a telephone number or Internet Protocol (IP) address associated with a user, the network may also route the communication based upon a dynamically updated trunk group identifier included in an updated routing function of the network.

摘要： A system and method for providing telecommunications special services to customers of a communications service provider includes receiving first communications signals from customer premise equipment. The first communications signals may be processed using a special services card to generate second communications signal. The second communications signal may be communicated to a line termination unit operating externally from a BBDLC. The second communications signal may be processed by the line termination unit to generate a third communications signal. The third communications signal may be communicated to a transport card operating in the BBDLC. By externally processing special services signals from the BBDLC, bandwidth of the BBDLC may be utilized more efficiently.

摘要： A method of selecting an optimum impedance for a loop start trunk line, comprising successively applying respective ones of a plurality of impedance settings to the loop start trunk line, for each impedance setting measuring the impulse response of the trans-hybrid echo path by applying audio test signals to obtain a time-domain trans-hybrid transfer function and deriving a frequency-domain spectrum representative of trans-hybrid loss, and then calculating figure of merit of the transfer function based on the power spectrum. Once all impedance settings have been tested, the optimum impedance is selected as the impedance setting associated with the highest calculated figure of merit.

摘要： System resources are pooled and allocated in an optimal manner to handling telephone voice traffic or to handling computer data traffic. A combination of mechanisms is used to achieve higher statistical multiplexing on a network interface by dynamically adjusting the multiplexing. The system: 1) Provides homogeneous access to DS0 trunk resource by both voice and data traffic, resulting in a larger resource pool. 2) Partially normalizes the class of service characteristics of data traffic to make it more predictable and can dynamically adjust the bandwidth such that requests for resources can be honored with a higher success rate, and 3) Maintains multiple qualities of service for multiple voice and data streams drawing from a single resource pool. Data traffic is normalized into flows, each of which has an assigned priority and bandwidth is allocation to each of the flows.

摘要： A method and apparatus are provided for the management of multiple-node networks to provide for efficient and rapid determination of an alternative connection path through the network to avoid a fault in the connection path. The present invention seeks to minimize the number of nodes affected by the alternative connection path by systematically seeking alternative, non-retracing connection paths from nodes neighboring the connection fault. Until an alternative connection is found, searches are conducted from nodes further from the connection fault. Optionally, the present invention may use a retracing path to establish a connection.
