Switch SW1-1 through SW1-8

Switch SW1-1 Line Coding: HDB3 (default)

Use Switch SW1-1 to control the Network Line Coding options. Set
these options to be the same as the Line Coding given to you by your
Service Provider. If you are using two Model 2707s together as short
range modems, set both units to HDB3.
