I am in the process of selecting hardware to implement a communications server. The server will be a Unix based platform connected to a LAN and will have a model pool attached to allow employees to dial-in. To improve security, it has been decided that a callback should be required before system access will be granted. I have been investigating the use of the Microcom HDMS system which appears to have a reasonable callback strategy; however, we have had poor results with the AX/9624c connecting to non-Microcom modems, if the unit is configured for MNP class 6 communications ( required for 9600 bps operations). Does anyone know how to configure this modem to communicate with other brands of modems and to properly fall back to 2400 bps or 1200 bps when necessary? Does anyone know of an alternate solution for a modem pool w/callback support? I have grown fond of the Telebit modem but its callback directory permits only a limited number of entries. So maybe, a separate callback unit would be the best solution. I would appreciate any suggestions - even commercials.
