[Asterisk-Users] Motherboard failure with 2 Digium TE405P car ds

Wed Apr 20 21:54:27 MST 2005

Have you tried using a CSU/DSU between each of the T1's on that system?

The problem could be a voltage issue on any of the 7 T1's running into
that box.

If you have the 7 CSU/DSU's it might be worth while to try running all
7.  If not, try 1 at a time and see if the CSU/DSU notices any problems
with each.

Seems odd, though I would suspect the boards.

Have you tried higher end boards, like compaq proliant servers?

For this particular server all telco equipment is in a climate
controlled room kept at 66 degrees F and they are all on APC SmartUPS
rackmount power battery backups, Also all of these connections had
previously been connected to other Digium cards in the last year with no
issues.

Check the telco equipment you are plugging into (PBXes) with the
crossovers.. Unless they are all on the same power grid and protected I
would blame them. my two cents...
