A service is provided to cell phone subscribers to improve reachability. A home location register node maintains state information on a subscriber's cell phone status. Cell phone status information includes: off; on, registered and available to receive calls; on, registered but busy participating in an ongoing call; on, registered but temporarily unavailable; and on, registered but unattended. Temporarily unavailable is further qualified: poor reception location, high interference, cell throughput saturation, intentional user disposition. Long term unavailability may also be inferred and indicated depending on the device and/or system status. When a call to a subscriber's cell phone cannot be completed or is not answered, the service annunciates the reason to the calling party. The calling party can then make a more informed decision as to when to reattempt the call and is more likely to reattempt the call. The service is provided in conjunction with call forwarding to landlines phones and/or voicemail.

A technique for qualification of loops for new digital subscriber line services (DSL) involves use of an expert system, such as a neural network. A database of loop characteristic information and performance data enables the expert system to train or learn how to predict performance for future loops. In response to data characterizing a new loop to be qualified, the trained expert system predicts digital subscriber line performance for the new loop. Typically, the prediction enables classification of service capacity for the new loop into one of several classes corresponding to levels of DSL service offered through the network. The database for use by the expert system is updated as each newly qualified loop is brought into service and actual performance for that loop is known.
