Abstract: Blocked traffic is monitored in a telecommunications network. Respective switch data is collected from each of the switches including respective routing tables and trunk performance parameters for a current time period. Final trunk groups are identified for each respective switch in response to the respective routing tables. The number of circuits within each final trunk group is determined. The total usage of each of the final trunk groups is determined in response to the respective trunk performance parameters. A blocking value for each of the final trunk groups is determined. A network portrayal is generated wherein each of the switches is depicted according to one of a plurality of ranges of aggregate blocking values for each respective switch. A plurality of switch portrayals is generated wherein each switch portrayal depicts each final trunk group within a respective switch according to a plurality of ranges of blocking values.

Abstract: Trunks in a telecommunications network are monitored. Out-of-service data is gathered from each respective switch corresponding to a current time period for a plurality of trunks connected to the respective switch. Switches that have at least one out-of-service trunk are detected in response to the gathered data. A first plurality of graphic elements is displayed via a web page corresponding to respective switches, wherein each switch detected as having an out-of-service trunk is displayed with a distinguishing visual characteristic. One of the first graphic elements is manually selected for a selected switch. Second graphic elements are displayed for respective trunk groups corresponding to the selected switch, each second graphic element having a respective size proportional to a current number of call attempts directed to the respective trunk group during the current time period and having a color indicative of a health index of the respective trunk group.
