Which Continuum controllers support RAS via modem connection?
Not all Continuum controllers support modem connection.
The access point for a remote site is the controller that is configured with a modem that is used to establish a communication link with the remote CyberStation.
Only the following Continuum controllers can act as access points for remote sites.
CX9900, CX9940, CX9680, CX9640, CX9200, CX9924.
Note that other controllers communicating with the access point controller via ethernet can fully participate in RAS communications as the access point controller will route messages to/from its peers.
