I have the same problem with two PCs and ISDN, both of them with 2.2 kernels
(2.2.12 and 2.2.14). One of them has a Teles 16.3 ISA, and the other has a
Billion ISA.

I have another PC, kernel 2.0.35 and a Teles 16.3 ISA, and works OK.

All of them have mtu 1500

Could it be a problem of 2.2 kernels??????

Regards
