Data/Fax Rack Mounted Modem Card Configuration Guide 7

Chapter 2 – Hardware Settings

Setting DIP Switches

The MT5600-V92 modem card contains sixteen DIP switches. How a switch operates depends on whether the

modem is in synchronous or asynchronous mode (DIP switch #12).

Factory defaults are set to use the MT5600BR-V92 to dial up a remote installation where the call is answered

automatically. Your communications software may require different settings. For the correct DIP switch settings,

check your software’s documentation.

Before you install modem cards in the card cage, verify that the DIP switch settings are correct for your

application (dial-up or lease line).
