At moment, I think the cable are properly connected, since I check out TE405P card, actually two ports indicate green. TE110P indicate Green. And GSM Gateway LAY1 indicate Green, but LAY2 indicate blinking green. I am tying to process the following work according to http://www.cadvision.com/blanchas/Asterisk/DahdiT1trunk.html And may I have some general ISDN questions: according to dahdi_tools, I would be able to check configuration from TE405P card. It has following configurations : Current Alarms: No alarms. Sync Source: T4XXP (PCI) Card 0 Span 1 IRQ Misses: 0 Bipolar Viol: 0 Tx/Rx Levels: 0/ 0 Total/Conf/Act: 31/ 31/ 0 1111111111222222222233 1234567890123456789012345678901 my question is what is meaning of each of configuration mentioned above?
