Maybe its important to mention:
- Both LEDs of the E-1 card are blinking red
- Used cables for the RJ45 plug (CAT5): orange/blue
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

OK, I think I know where the problem is - there must be a cableing
problem with the Twinax connectors.
So there is my next question:
Which pin of Y01 is TX+ and TX-?
Which pin of Y02 is RX+ and RX-?
Greetings,
Holger

the led's keep blinking red all the time during OpenBSC operation, seems to be
a hfcmulti driver bug that doesn't set the LED's correctly.
