A method and system enable optimization of trunk group design in a public switched telephone network (PSTN). A community of interest, including two end offices connected by a direct trunk and at least one tandem switch, is identified using out-of band signaling data collected from the PSTN. An application server interfaced to the PSTN determines whether traffic in the community of interest passes through the tandem switch during a predetermined time period. When traffic passes through the tandem switch, the application server further determines whether the direct trunk between the end offices experienced an overflow condition during the same predetermined time period. When the direct trunk did not experience an overflow condition, an exchange code associated with the traffic passing through the tandem switch is designated as a misrouted code. The misrouted code is flagged so that associated traffic is redirected through the direct trunk.

The present application discloses an automated digital subscriber line performance control system comprising a computer system including a logic module to evaluate performance of a plurality of DSL lines and to automatically select a set of DSL lines from the plurality of DSL lines, a line profile database responsive to the computer system, the line profile database providing a plurality of line profiles in response to a request from the computer system, and a digital subscriber line access multiplexer coupled to the computer system. The digital subscriber line access multiplexer is configured to measure a performance parameter of a plurality of physical DSL lines and to change a profile for at least one of the plurality of DSL lines. The set of DSL lines has degraded performance characteristics based on historical performance data.

A system, computer readable medium, and method for multi-tiered data access. The method includes the steps of determining a first search parameter and a second search parameter in response to an operator initiated command, determining a physical location of a data unit corresponding to the first search parameter, identifying a data member corresponding to the second search parameter, and outputting the data member to an operator interface device.

A system and method are described for selecting a service state using a configurable abstraction layer. A comparison is made between network parameters of a Network Performance Layer and network services of a Service Layer. Once network parameters are within a threshold for providing a given service, a state change can be made in the configuration parameters to suit the provided service.

A method and system for managing performance data of communication lines, such as digital subscriber lines, is disclosed. The method includes receiving from a remote user device an identifier for a particular communications line at a web server; initiating a real-time performance analysis of the line at a network end of the line; receiving real-time performance data and converting the real time performance data to analyzed data; receiving field performance data from the user device; and converting at least one of the field performance data and the real-time performance data from a web-based format to a mainframe format; and sending the converted data to a mainframe for storage corresponding to a file associated with the identifier.

Access to network elements of a telecommunications network is integrated through a common access point by an integrated access application which receives a request for communication with a network element. An element management system (EMS) group, including at least one EMS server, associated with the network element is identified. The at least one EMS server is queried to identify an active EMS server and to determine whether the active EMS server has an available connection sufficient to support the request. When the active EMS server has the available connection, the request is sent over the available connection. When the active EMS server does not have the available connection, the request may be buffered and, after a predetermined time, it is again determined whether the active EMS server has the available connection. When the request is sent, it may be multiplexed with other requests over the same available connection.
