Hi,
What does the led OK for WIC-1B-S/T mean ? On my T0 connexion, it is sometimes green, at other times no light at all.
Is it a configuration mistake or a problem with the line ?

Hi,
Looking at this book
Page 12
Step 6
Check that the OK LED goes on, which indicates that the ISDN port has established a connection with
the central office switch.
Check/replace cable -- or it could be a TELCO issue

Hi,
According to google searches this is almost certainly a TELCO issue.
The only other thing I can think of is are using the correct
ISDN switch type.
For france there seems to be a couple
basic-net3 and vn3

Thanks !
I'll call our Telco.
I think the ISDN switch type is good since the same configuration is used in other center of the same company.
