Abstract:

A system and method for automated monitoring of availability in xDSL access networks are disclosed. An xDSL access network with network availability monitoring generally comprises a measurement device in communication with a DSL access multiplexer (DSLAM) at a central office (CO), a broadband remote access server (BRAS) in communication with the DSLAM, a remote authentication dial-in user service (RADIUS) server in communication with the BRAS, and a data collector at a network operations center (NOC) in communication with the RADIUS server and the measurement device, the data collector being configured to retrieve data from the RADIUS server, the measurement device being configured to automatically establish a PPP session with the BRAS and the RADIUS server being adapted to collect data relating to the PPP session. The measurement device is preferably connected to the DSLAM via an xDSL loop terminating at a DSLAM monitoring port. In addition, the PPP session is preferably authenticated.
