Controls on PC Board

The MT202TD circuitry is on a single printed circuit (PC) board.

This board contains one 8-position DIP switch (numbered 1-8),

an analog loopback test switch, and a digital loopback test

switch. The factory default setting is for 4-wire, full-duplex

operation in normal mode. If you are using the modem in a 2-

wire configuration or using one of the test modes, you must

change the switch positions. Refer to page 19 for switch

setting and function information.
