Clock refers to the JVT clock that must be present for
the unit to operate. Temperature alarm is reported if the
unit's operating temperature exceeds 93°C.
BUSY1, BUSY2 (yellow)
The BUSY1 and BUSY2 LEDs indicate the current
signaling status of the Line 1 and Line 2 respectively.
Steady on condition indicates a busy (off-hook) state.
Blinking LED indicates a ringing state.
