This object controls whether this modem can be managed remotely, offering enable(5), disable-local(8), or disable-local-and-remote(9), with the important caveat that once management is disabled at both local and remote units, it cannot be re-enabled from the remote side afterward. Admins must set this carefully, since choosing disable-local-and-remote(9) can permanently lock out remote management of that unit going forward. For example, an admin planning to manage a remote modem later should avoid setting mdmRemoteAccessMode to disable-local-and-remote(9), since that would require physical local access to ever restore remote management.
