Hello Holger,

I can't help with Linux (I use Windows), however I noticed
this in mISDN (hfc_multi.c) a while ago:

  case 1: /* HFC-E1 OEM */
  /* 2 red blinking: NT mode deactivate
   * 2 red steady:   TE mode deactivate
   * left green:     L1 active
   * left red:       frame sync, but no L1
   * right green:    L2 active
   */

So I would guess that there is a synchronisation problem which is not
related to the TEI setting. Maybe there is something wrong with the
wire connection. If you can see the signal sent from the E1 card at
the BS-11 and there is also a signal sent from the BS-11, than probably
the signal from the BS-11 is not received by the E1 card so it could
not synchronize on it.

Best regards,
  Dieter
