Further to my post last month, I've done the following but still have problem in getting the linkset up.. 1. Installed two trixbox PC with trixbox 2.8.0.3 (Dahdi version 2.2.0-4 and Asterisk version 1.6.0.10-5). 2. Each trixbox is equipped with a Sangoma A101 card (No echo cancellation hardware) configured with Sangoma Wanpipe driver version 3.5.11. 3. Configured both cards as E1 and TDM as voice protocol. 4. Connect both cards with a crossover cable (1-4,2-5 / 4-1,5-2) 5. Setup the following configuration files: TRIXBOX 1 - /etc/dahdi/system.conf span=1,1,0,ccs,hdb3,crc4 bchan=1-15,17-31 dchan=16 echocanceller=mg2,1-15,17-31 loadzone=us defaultzone=us /etc/asterisk/chan_dahdi.conf [channels] echocancel=no echocancelwhenbridged=no group=1 signalling=ss7 ss7type=itu ss7_called_nai=national ss7_calling_nai=national linkset=1 pointcode=1 adjpointcode=2 defaultdpc=2 networkindicator=national sigchan=16 cicbeginswith=1 channel=1-15 cicbeginswith=17 channel=17-31 ss7_internationalprefix=00 ss7_nationalprefix=0 TRIXBOX 2 - /etc/dahdi/system.conf span=1,1,0,ccs,hdb3,crc4 bchan=1-15,17-31 dchan=16 echocanceller=mg2,1-15,17-31 loadzone=us defaultzone=us /etc/asterisk/chan_dahdi.conf [channels] echocancel=no echocancelwhenbridged=no group=1 signalling=ss7 ss7type=itu ss7_called_nai=national ss7_calling_nai=national linkset=1 pointcode=2 adjpointcode=1 defaultdpc=1 networkindicator=national sigchan=16 cicbeginswith=1 channel=1-15 cicbeginswith=17 channel=17-31 ss7_internationalprefix=00 ss7_nationalprefix=0 With both setup, I've ran dahdi_scan on both machines and got the following result on both machines: [trixbox1.localdomain ~]# dahdi_scan [1] active=yes alarms=OK description=wanpipe1 card 0 name=WPE1/0 manufacturer= devicetype= location= basechan=1 totchans=31 irq=0 type=digital- syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=HDB3 framing_opts=CCS,CRC4 coding=HDB3 framing=CCS Visually, I can see both cards status LED is showing green which means good connection.
