Maintenance Connectionsbbbbbbbbbbbbbbb
Common types of console terminals are used for both switch and local DEFINITY
LAN Gateway maintenance, allowing the same baud rates and parity to be used.
Although a local maintenance terminal is optional, it does need to be available for
installation and troubleshooting.  A remote maintenance terminal may also be
used.
