Bernard,

I use ntt as I am working in Tokyo with 2 ISDN lines.

Regarding the calls, I can ping from the 2504 (spoke1) now as I changed the
ISDN line used by the 2523 (hub) but I still cannot ping from the 2523.

Here is the debug. Note that the TEI given automatically by the ISDN switch
change after clearing the lines. Moreover, I receive a TEI=77 which I don't
know at all! Do you know why all this happen?

hub#clear int bri0
hub#
1d04h: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BRI0, TEI 79 changed to
down
1d04h: %ISDN-6-LAYER2UP: Layer 2 for Interface BR0, TEI 78 changed to up
hub#deb ppp authe
PPP authentication debugging is on
hub#sh deb
