-Z Display Current Authentication Credentials

A diagnostic aid when modem registration fails after it has previously been able to successfully register. It shows the current values for the ASN (sequential) and ARN (random) authentication numbers.

Zero values imply that the user has inadvertently reset the modem’s credentials, usually by reloading the IP Address.

Non-zero values imply that the carrier has for some reason reset the IP Address being used, or that the modem and MDIS have gotten out of synch due to registration protocol issues under marginal coverage conditions (quite unlikely). The credentials must be forced to match. In the former case, the carrier must be asked to rest the IP address. In the latter case, both the user and the carrier must reset the IP Address
