It is RED. It means that no either there is no physical connection to
the remote side, or otherwise both sides don't agree on the definitions.

Those three were not configuerd (have no span= entries in zaptel.conf, I

Or, to phrase it in layer 1 terms: CAS (for MFC/R2) or CCS (for ISDN)?

We're staying in layer 1 for the moment because the issue is the RED

An output of 'head -n 1 /proc/zaptel/*' after the fact might help us help
you. Did you re-run ztcfg after editing zaptel.conf ?

The TE412P supports R2 just as well.
