Hi, I've been playing with Dahdi and OpenBSC (I have an old T100P card) and something I'm a little confused about is what is the proper configuration for system.conf? Does dahdi itself take care of the hdlc/lapd signalling (in which case I'd expect the signalling channel to be set as dchan in /etc/dahdi/system.conf) or is openbsc taking care of the hdlc/lapd signalling (in which case I'd expect the signalling channel to be set as clear)? Thanks, Gus Bourg
Dahdi takes care of the signalling, in a manner of speaking. For OpenBSC, the signalling channel should be a "dchan". Matthew Fredrickson Digium, Inc. On Mon, Feb 7, 2011 at 1:17 PM, Gus Bourg <gus@bourg.net> wrote:

Normally you'd do HDLC inside DAHDI and do LAPD inside OpenBSC. This is what happens if you do 'dchan=1'. -- - Harald Welte <laforge@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
