Abstract

In various embodiments, a management system may query connection devices for their capabilities and store the information in a data structure. In some embodiments, the data structure may be in a form of a Deducible Capability Numbering (DCN) number. In some embodiments, the DCN number may describe the capabilities of a connection device using a series of representative numbers. After connecting the connection devices, the management system may continue monitoring capabilities of the connection devices and line failures. The management system may reconnect connection devices based on their capabilities if a line failure occurs.
