Remove the card for two to three seconds and then reinstall it. If the failure
continues, you must replace the card. Use the following procedure to replace
the card:
1 Locate the node of the bad card:
a Open the ITG ISDN IP Trunks application in MAT.
b In the upper part of the IP Telephony Gateway - ISDN IP Trunk
window, click on the site name. All the cards in the node are listed
in the lower part of the window.
c Locate the card to be replaced in the lower window by card TN.
2 Disable the bad ITG card in LD 32 by using the DISI command.
3 If the card that is to be replaced is an 8-port NTCW80AA card,
disconnect the T-LAN Ethernet cable from the faceplate of the bad
card. Label the cable to identify that it is the T-LAN Ethernet
connection so that you can later reattach it to the replacement card.
If the card that is to be replaced is an 8-port NTCW80CA or a 24-port
NT9061AA card, disconnect the T-LAN Ethernet cable from the I/O
cable. Label the cable to identify that it is the T-LAN Ethernet
connection so that you can reinstall the cable on the replacement card.
