Configuring the Modem

Configuring the Modem

You configure the modem using the three sets of DIP switches on the bottom of the modem.

,

IMPORTANT

It is important to follow the three steps described below, in the order shown, to ensure that you configure your modem properly using the modem DIP switches:

1.Use DIP switch 3 (SW3) to configure the modem for your host DTE interface and network topology. Using SW3, you select the modem to operate in high-speed fast-poll or low-speed (FSK) mode.

2.If you set SW3 for FSK mode in step 1, use DIP switch 2 (SW2) to configure the modem for either Bell 202T or ITU-T V.23 compatibility. Otherwise, you can use the modem in fallback mode.

3.Use DIP switch 1 (SW1) to select the modem’s transmitter output level and receiver dynamic range. The SW1 settings apply for both high-speed fast-poll and low-speed (FSK) modes.
