Telephone console LEDs
Telephones and attendant consoles have some alarm LEDs that must be checked out.
Attendant console LEDs
The console has two red LEDs, labeled “ALM” and “ACK”. The ALM LED lights steadily when
there is a major or minor alarm at the server. The ACK LED lights steadily if the alarm has been
successfully reported to INADS. If the server is unable to report the alarm to INADS, the LED
flashes; this signals the attendant to call INADS and report the alarm.
Terminal alarm notification
Terminal Alarm Notification is an optional feature that displays several types of alarms on
telephones with administered feature buttons or the attendant console. A maximum of 10 digital
and/or hybrid telephones may be used.
When an alarm occurs, the green status LED associated with the assigned button is in a steady
state. The LED may be turned off by pressing the button associated with the LED. If the LED is
off and the alarm has not been resolved by the time maintenance reschedules testing, the green
status LED resumes its steady state.
DS1 Converter circuit pack LEDs
Eleven LEDs provide an indication of the state of the Figure 67: TN1654 DS1 Converter circuit
pack LEDs and the T1/E1 facilities. The top group has the standard red, green and yellow
LEDs. The red LED indicates an alarm condition and the green LED indicates testing in
progress. The four SPAN LEDs indicate the status of the T1/E1 facilities. The four STATUS
LEDs currently are unused and remain off.
