What type of E1 adapter do you use? If you use an accurate clock source, Work and Set values should be similiar (I have Set Value 1024, Work value 1023, and I've used Nateks E1 SDH Mux with High-Stability Stratum oscillator when calibrating). See http://bs11-abis.gnumonks.org/trac/wiki/isdnsync
The observed difference of "Work Value 1104" and "Set Value 1082" should be no problem. From my measurements a difference of about 100 of those values means about 0.1 ppm. And 0.1 ppm is good enough that most phones should see the BS-11 and the offical networks.
I guess there is some other problem, I would also check if bs11_config shows that the TRX is loaded. And maybe start with a configuration file which uses only one TRX.
Best regards, Dieter
Hi,
thanks for your replies. It was a problem with the old misdn stack. Seems to work fine now :)
Best regards, Martin
