Circuit Pack LEDs

The bottom four LEDs on the TN1654 board are labeled SPAN LEDs. These

LEDs are under firmware control. If the facility is not administered, then the LED

is not lit. The LED is lit amber if the facility is running alarm free. If the facility is

detecting either a red alarm (loss-of-signal or loss-of-frame), a yellow alarm

(remote frame alarm) or a blue alarm (AIS signal) then the LED is lit red. The

SPAN SELECT switch on the TN1654 faceplate is for future use. Pushing the

switch will have no effect on the board. See

Figure 6-3 on page 6-13

for a view of

the faceplate on the TN1654 DS1CONV circuit pack.
