<p>Hi All,</p>
<p> I am facing problem with E1 line. I have installed Asterisk (1.4.20.1) on a system with Digium TE420 card (Zaptel- 1.4.10)</p>
<p> But every now and then I face problem of down E1's. The log show lot of entries like</p>
<p> "pri_dchannel: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 2"</p>
<p> This happens on a regular basis and the E1 becomes up after some time.</p>
<p> My zaptel.conf is as follows:</p>
<p> </p>
<p># Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)<br />span=1,1,0,ccs,hdb3<br /># termtype: te<br />bchan=1-15,17-31<br />hardhdlc=16<br /><br /># Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2"<br />span=2,2,0,ccs,hdb3<br /># termtype: te<br />bchan=32-46,48-62<br />hardhdlc=47<br /><br /># Span 3: TE4/0/3 "T4XXP (PCI) Card 0 Span 3"<br />span=3,3,0,ccs,hdb3<br /># termtype: te<br />bchan=63-77,79-93<br />hardhdlc=78<br /><br /># Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4"<br />span=4,4,0,ccs,hdb3<br /># termtype: te<br />bchan=94-108,110-124<br />hardhdlc=109<br /><br /># Global data<br /><br />loadzone = us<br />defaultzone = us</p>
<p> </p>
<p> Any advice what could be the problem..?</p>
<p> Thanks in advance !</p>
