Upon connection, the caller is prompted for a valid user ID and password. If a match is found in the Dial Access Security database, the caller is either passed through for immediate access, called back at a fixed location, or called back at the number requested. This feature provides a built-in security database for up to 40 users. Any one of the 50 passwords can then be verified at link negotiation, providing link security for the network manager and seamless operation for the user. This allows a central site manager to change remote users' modem configurations without having the modems returned or making time-consuming field support calls.
Configurations are password protected to prevent tampering.
The modems also offer a flexible scripting language which allows you to customize and automate security logon procedures, enhancing ease of use, flexibility, and convenience for the remote user. Both modems automatically redial and restore a dial connection lost due to poor phone conditions, eliminating the need to restart an aborted file transfer. If the leased line no longer supports data communications, the modem will automatically switch to the two wire dial backup line. In the event the leased line does fail and the dial backup line is in use, the modem will periodically sample the leased line to determine whether it has returned to a state sufficient for data transfer.
