Abstract
Abstract A system and method automatically configures protocol layer parameters in terminal and carrier equipment. The system includes a terminal equipment having an automatic configuration program. The automatic configuration program controls the operation of the terminal equipment and sends a series of probe to the carrier equipment. Each probe is constructed to test a specific parameter value, and to restrict a set of potential values for the parameter. The automatic configuration program receives answers back from the carrier equipment, which may accept or reject, or not respond to the probe. Based on the the probe, any previous probes, the answer, any previous answers, and the set of values for the parameter, the automatic configuration program constructs another probe in accordance with another value of the parameter. This other value is determined by restricting the set of potential values that may be used to configure the parameter. The automatic configuration program thus, tests a plurality of the applicable parameter values for a parameter and iteratively narrows the set of potential values until the parameter value is established, or some error condition is encountered the prevent configuration of the parameter. This process is repeated for additional parameters, and then successive protocol layers.
