Front Panel Features
The unit contains six LEDs for a quick visual indication to the
status of the circuit, two bantam-type bridging jacks for trans-
mission path testing, a DB-9 connector with a female RS-232
interface for craft terminal access, and test points for measuring
span current. A description of each is provided below.
