Instead, I get > none. I think there may be somthing more systematic about this. A friend of mine (who has an ISDN line from CCL (the local cable TV company)) gets these CRC errors (but i4b otherwise works fine for him). My ISDN line is provided by BT, and I do not see CRC errors. With BISDN, it was notable that the CCL lines gave frequent TEI-Check-Request messages, wheras the BT line hardly ever used Check-Request except at startup. This was observed with an older i4b (before the recent lower-layer rework); if the CCL lines still behave oddly with the latest release, I will try to get hold of some more info.
