A UC500 running 12.4(22)YB1 (IOS in Early Adopter package 7.1.1) and with a T1/E1 VIC installed, will experience the following problem when trying to configure the Voice Card:
UC520(config)#card type t1 0 2
To configure card type command install HWIC T1E1 license first.
Please use:license install <filename>
This is a software issue documented by the following bug report:
CSCsz85550 license requested when entering card type T1 (VWIC-2/MFT1-T1/E1) uc520
The workaround is to upgrade the IOS to an image with the fix. To obtain an image with the fix, please open a case with TAC. Support information can be found on:
