Abstract

Example methods and apparatus to trigger maintenance and upgrades of access networks are disclosed. An example method comprises obtaining a first value representing a number of unassigned ports associated with a first digital subscriber line access multiplexer (DSLAM), obtaining a second value representing a projected number of ports associated with the first DSLAM needed to satisfy at least one of anticipated, projected or pending service requests, and determining whether to automatically submit a preventative maintenance trouble ticket for the first DSLAM based on the first and second values.

comparing the computed capacity gap to a second threshold to determine whether to automatically flag the first digital subscriber line access multiplexer for a capacity upgrade.

9. A method as defined in claim 8, wherein computing the capacity gap comprises:

computing a first sum of the first and third values; and

subtracting the second value from the second value.

10. A method as defined in claim 8, wherein the second threshold comprises the first threshold.

11. A method as defined in claim 8, wherein the third value represents the number of bad ports or potentially bad ports associated with the first digital subscriber line access multiplexer and a number of bad loops or potentially bad loops associated with the first digital subscriber line access multiplexer.

12. An apparatus comprising:

a trouble ticket system;

a loop facility assignment and control system to provide a first value representing a number of unassigned ports associated with a first digital subscriber line access multiplexer;

a capacity-planning server to provide a second value representing a projected number of ports associated with the first digital subscriber line access multiplexer needed to satisfy at least one of anticipated, projected or pending service requests; and

an availability analyzer to compare a first ratio of the first and second values to a first threshold to determine whether to automatically submit a maintenance trouble ticket for the first digital subscriber line access multiplexer to the trouble ticket system, the submitted trouble ticket identifying that one or more bad ports associated with the first digital subscriber line access multiplexer are to be investigated.

13. An apparatus as defined in claim 12, wherein the loop facility assignment and control system is to provide a third value representing a number of bad ports or potentially bad ports associated with the first digital subscriber line access multiplexer, and wherein the availability analyzer is to compute a capacity gap for the first digital subscriber line access multiplexer based on the first, second and third values and to compare the computed capacity gap to a second threshold to determine whether to automatically flag the first digital subscriber line access multiplexer for a capacity upgrade.
