24. Using the Modem s Auto Connect Feature Your SM9256D modem can emulate a leased line connection over the Public Switched Telephone Network PSTN Using the DL command you can configure the modem to work similarly to the always connected functionality used with leased lines This feature is useful in environments where a leased line is not available or is cost prohibitive In certain environments this feature is more robust in recovering from network failures When the DL command is used your SM9256D modem automatically dials the first of four telephone numbers you have stored using the amp Zn x command If the call fails or is disconnected your modem waits a user defined number of seconds before redialing the number If the redialing attempt fails to make a connection for example if the number dialed is busy or the called modem does not answer your modem automatically dials the next number stored with the amp Zn x command The modem repeats this round robin method until a dialed number results in a data connection Storing Telephone Numbers Before you use the amp Zn x command store up to four telephone numbers in your modem s nonvolatile memory These are the telephone numbers your modem automatically dials when it executes an DL command In the command amp Zn x is a decimal number from 0 to 3 that corresponds to a location in the modem s nonvolatile memory and x is a dial string up to 31 characters long The following
