CHAPTER 3: Configuring the Hardware DIP Switches
3.1 Configuring DIP-Switch S1
DIP-switch S1 is where you configure the data rate, asynchronous or synchronous
data format, transmit clock source, and response to RDL request. Table 3-1
summarizes default positions of DIP-switches S1-1 through S1-8. Detailed
descriptions of each switch follow the table.

NOTE
When setting the IDSL Line Driver for SNMP management, the DTE rate
switches (S1-1, S1-2, and S2-1) must also be set to the ON position.

Use Switches S1-1 and S1-2 to configure the asynchronous or synchronous data
rate of the IDSL Line Driver. Each setting represents one synchronous data rate
and one asynchronous data rate.
