Does anyone know how to monitor * to see if they are receiving timing slips on a span connected to a T100P card? I am seeing b-channel restarts quite often and also getting "No D-channels available" warnings from time to time. Yesterday I had all the b-channels crash during a MeetMe Conference. Not good! This PRI is connected to an Avaya Definity PBX that is onsite and located in the same room as *. * is set to clock off the Definity. I am seeing no problems on the PRI from the Definity side. zaptel.conf is as follows: span=1,1,0,esf,b8zs bchan=1-23 dchan=24 defaultzone=us loadzone=us zapata.conf is as follows: switchtype=national overlapdial=yes signaling=pri_cpe group=15 channel => 1-23 usecallerid=yes callerid=asreceived musiconhold=default echocancel=yes echocancelwhenbridged=yes echotraining=yes Thanks.

Many PBXes have no support for this since their "default" role is to sync off of the telco PRI they're connected to. Now having said that, my Norstar MICS is set ClockMstr and the T100P is clocking off of it without any issues whatsoever (about 2 months now). It might be prudent to try letting the T100P not try to sync to the PBX and see if that helps. Also, have you run zttool to see if any clockslips or missed interrupts are being logged? Issuing a "make zttool" in the zaptel source directory will build it, but it requires libnewt, which may be difficult to obtain, depending on your distro. -A.

We've been running connected to our Definity G3si R6 via TN767 <--> TE410P and have had no problems. Our zapata.conf settings our just a little different, might give you something to try. We had some strange problems when set as you have above. switchtype = 5ess overlapdial = no signaling = pri_net
