DATA Red (solid) The T1 is in red alarm or T1 sync loss has occurred.

Yellow (solid) The T1 is in test.

Green (solid) Layer 2 is up.

VOICE Red (solid) The T1 is down.

Green (blinking) The phone is off hook.

Green (solid) The T1 is up and the phone is on hook.

BATT Off AC has failed and no battery.

The only difference in the 604/608 TDM LEDs and the 612/616/624 TDM LEDs is in the

Voice LED. For the 604/608, the Voice LED is off if the T1 is down. For the 612/616/624,

the Voice LED is solid red if the T1 is down.
