Connect the DTE To connect the DTE to the modem, you can use two DB25 to 8-position modular adapters and an 8-pin RJ45-type modular cable instead of an RS-232 cable with DB25 connectors. Because of the large number of cables required for typical 3821 Plus installations, the slimmer modular cable is recommended. - Page 9 Selecting Configurations Using the SDCP The SDCP’s Liquid Crystal Display (LCD) consists of two 16-character lines which display modem status, control functions, and configuration options as well as indicating your location in the Top-Level menu tree.

- Page 10 Selecting Configurations Using AT Commands When using AT commands, the following criteria must be met: Make sure the asynchronous DTE’s communication software is configured for 10-bit character format (for example, 8 data bits, no parity, and 1 stop bit). Make sure the DTE (RS-232D) cable is attached to the DTE connector at the rear of the COMSPHERE 3000 Series Carrier, and to the correct serial communications port on the asynchronous DTE.
