Disclosed is a provisioning tool and method for a communications network, particularly a broadband communications network which is arranged to provision a service for a user based on information available via another user connection; this facilitates provision. A radio receiver selects a transmission standard based on the type of its energy supply. The method includes forming sourcedrain regions by doping a second material with a second type of impurity different than the first type of impurity, wherein the second material has a smaller bandgap than the first material. In this manner, the particular length of each pit and land on the disc can be individually selected based on nominal symbol length, as well as other factors including radial and angular locations of the pits and lands on the disc.
