Good luck with it.
I think I am lucky! ;-)
We resolved the problem changing the Mother board to one with an Intel chipset. The first one had Via chipset.
1) At first, we changed the mother board by another with Intel chipset. This one can set udma2 (or udma3) from BIOS. It is set up to udma2.
# ChannelBank 1 - T1 span=1,0,0,esf,b8zs fxoks=1-24
# ChannelBank 2 (Empty) - T1 span=2,0,0,esf,b8zs fxoks=25-48
# Empty - T1 span=3,0,0,esf,b8zs fxoks=49-72
# Telco E1/PRI span=4,0,0,ccs,hdb3 bchan=73-87 dchan=88 bchan=89-103
The messages "HDLC Bad FCS" and "HDLC Abort" stopped!
2) After that, we set up span 3 and 4 (3rd and 4th ports on the card) as E1.
We are going to use 2 E1s/PRI (different Telcos) and 2 T1s (channelbank).
[...] # Telco1 span=3,0,0,ccs,hdb3 bchan=... dchan=... bchan=...
# Telco2 span=4,0,0,ccs,hdb3 bchan=... dchan=... bchan=...
-> The jumpers were set to E1 and the channels were also correct.
-> After each modification it was necessary to reboot and take off the power cable for modifications to take effect.
What timing/clock configuration do you recomend us? Zero for everyone?
span=1,0,0,esf,b8zs # T1 ChannelBank1 span=2,0,0,esf,b8zs # T1 ChannelBank2 span=3,0,0,ccs,hdb3 # E1 Telco1 span=4,0,0,ccs,hdb3 # E1 Telco2
By the way, could you explain in a better way what does these timing options (0, 1, 2) mean?
