Switch S1-8: Loopback Test Enable

Depending upon the setting of switch S1-8 the Model 2703 will either be continually in loopback mode, or loopback mode will be enabled by pressing and holding the front panel switch. Since the front panel switch is spring loaded–it returns to “Normal” operation when pressure is released–this DIP switch provides a way of leaving the Model 2703 in “unattended” loopback mode for remote test pur- poses.

S1-8	Setting
On	Continual “unattended” loopback mode
Off	Loopback activation by front panel switch
