Hi,
We currently have an Asterisk box (P4 2.4 Ghz, 512Mb RAM, 1 T100P, Zhone Channel Bank and 1 E100P) connected to an ISDN running without any problems. That machine is working for about 1 year.
Two days ago, we decided to switch that machine for two PowerEdge 600SC (HA) and we got some problems.
The running machine (P4 2.4Ghz) has an Intel motherboard with four 32-bit 3.3v PCI slots, which the T100P and the E100P are connected to. Great! No problem for almost a year.
Our PE 600 also has an Intel motherboard which only has one PCI 32-bit 3.3v slot and four 64-bit 3.3v PCI slots. First, we tried to get one of the PE 600 working, putting the Digium cards on it. We've put the T100P on the 32-bit slot (which is the slot 0) and the the E100P on the first 64-bit slot.
Searching for the T100P and E100P documentation, I've found only that the T410P works fine on 64-bit 3.3v PCI slots, but could not find any saying that wouldn't on the 64-bit 3.3v PCI slots.
After loading the module (wct1xxp) and starting the Asterisk, everything seems to be right. But after 3 or 4 calls, the problems begins. During the conversation, you can hear pop's on the call, and most cases, we lost the call. Looking at the messages file, the Asterisk reports:
PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 2.
Every time Asterisk reports this error message, that problem happens again. We've tried switching the card's slot, but did not work. Switching back to the old machine, everything works fine.
Some Info: PowerEdge 600SC with kernel 2.4.27 (non-SMP).
Zaptel.conf # Channel Bank span=1,0,0,esf,b8zs # E1 span=2,1,0,ccs,hdb3,crc4
Zapata.conf switchtype=euroisdn signalling => pri_cpe
Do you guys need more info? Any other log messages? thank you --oz
