Tried to configure WIC-1B-S/T-V3 on Cisco 2621XM but ISDN connection couldn't be established. Show ISDN status shows
"Layer 1 not active". But whenever a WIC-1B-S/T card is used the ISDN connection was sucessful. Cisco document says
the WIC-1B-S/T-V3 can be used If IOS 12.3(10) is used. We are curently running c2600-i-mz.123-26 ios and the issue still there.
Anyone who had experienced this before,Please assist in resolving this issue.
