Designate Modem Manager Server(s)
As with many of VTScada's services, it is possible to designate a workstation other than the primary configuration server to manage the Modem Manager Service.
In a multi-server application, the Modem Manager is configured to run on one workstation that was designated as its server. This can be any workstation that is licensed to operate as a server. It is prudent to spread services out, to distribute the load across workstations for larger applications.
You should have at least two servers: one as the primary Modem Manager server and the other as a backup server in the case that the primary Modem Manager server fails. Using a network device that shares the same modem between two servers may have unintended side effects.
