Modem Configuration
Before installing the modems (one attached to the Switch Management
Module’s console port and one attached at the user end to the terminal/PC),
configure them by this procedure:
1. Connect them, one at a time, to the PC or terminal and issue the appro-
priate AT command, as described in the tables in this appendix.
Note that, in each case, the configuration string for the modem attached
to the switch is different than for the one attached to the PC or terminal.
2. Install the modems in the appropriate locations. Make sure the correct
modem is installed in each location, according to how it was configured.
The modems listed in this appendix have been tested and found to work
properly with the Switch Management Module using the initialization strings
shown.
