hello ok, lets try it again: do the oml and rsl settings have to be identical? for example: one bts is set to port 0, ts 1, tei 25. the cfg entry would be "oml e1 line 0 timeslot 1 sub-slot full" and "rsl e1 line 0 timeslot 1 sub-slot full", right?
the cited link is useless, i kno it already, doesnt answer my question. what i wanted to know is why we have 2 types of settings (oml and rsl) which are identical, cause that told the openbsc.cfg. why do we need 2 settings that configure the same? or was the assumption above wrong?

why is it so difficult to understand that two different LAPD connections (on different SAPI) can either co-incide on the same E1 timeslot or run on different ones? Some BTSs support this (like Ericsson RBS2000), and OpenBSC supports it, too. Also, if you use A-bis concentrators, you might have even more than two LAPD connections on the same timeslot.
