Completing the T1 Configuration (ISDN PRI)
To complete the T1 ISDN PRI installation:
1 Return to the Digital Line Cards tab.
2 From the Select Device Type list, select ISDN PRI Channel List.
3 Click Apply.
4 Wait approximately 30 seconds for the status of each channel to change
from Ready to Idle.
While you are waiting, you may click Apply to refresh the list of channels
and to see the updated status. If you have connected the Telephone
company's T1 line to the T1 Digital Line Card or if you have connected a
loopback connector to the T1 card, the Nominal status light on the front
panel of the T1 board should now turn on (solid green). If the Nominal
status light does not turn on and you have the telephone company's T1
line connected, disconnect the T1 line and connect a loopback connector.
If the Nominal light now turns on, contact the telephone company for
assistance with the T1 line. If the Nominal light does not turn on, contact
3Com Technical Support.
The T1 card contains these status lights:
CF — Carrier Fail (when lit, indicates red alarm or blue alarm)
■
RA — Remote Alarm (yellow alarm)
■
LB — Loopback, when lit indicates that the card is in loop-back testing
■
mode. This light is not used to indicate any of the red, blue, or yellow
alarms.
