Dear Experts,
One of my customer is using Avaya Definity system version2.1. We have a total of 7 SSC port cabinets with 5 DS1 boards
in it. for past couple of days D channel of all DS1 show out of service. Initially we though that the issue might be with service provider. Service provider checked and confirmed that there is no issue from their end. Also CLAN link is up but unable to Ping the Clan. We have tried the below steps for trouble shooting.
• We tried by replacing the CLAN card, but even after replacing the CLAN card there was no ping response
• Tried by replacing the Ethernet adapter for CLAN
• Checked for the connectivity with onsite network switch, the connectivity was present
• Tested the connection to Avaya via term Port on cabinet. Avaya Definity system was accessible
• Tried deleting and adding the CLAN, but still the issue was not resolved
• Added new CLAN in another cabinet with new IP address but there was no ping
• Replaced the DC power supply.
• Refitted the motherboard connector for CLAN, but no ping response. Also changed the back plane interconnecting cable for Port network 1
• Tried rebooting the system, after reboot all DS1 and CLAN came up in service for around 30 minutes or so. after that first Ping response stopped and after few minutes D channel of all DS1 gone out of service. After that it never came up.
• Created a local unmanaged network to check the ping , but no ping response
• Swapped the control cards like Netconnect, tone/clock, etc. but no ping response
• Replaced the motherboard connector for CLAN.
• Checked all the associated program for CLAN and PRI signaling and synchronization, but still D channel is out of service
• Checked by replacing the DS1 card, but still the same.
• Created a local managed networks but still no ping response
• Changed SSC port cabinet, but still the issue is same.
Need your help as to how to troubleshoot the issue
Regards
