I just noticed today a large number of channels locked out on 3 modem cards. One of them had all but the last one and a D-channel left enabled! The others were 1/3 to 1/2 dead, all the modems locked out in pairs. This has probably been going on a while, but since we reboot everything on Sundays, I just happened to be looking at these chassis late enough in the week to see the problem today. Just now having access to TCM and looking at the inventory, I can see that the problem is happening on only (and all) of our hw 0.54.0 rev DSP cards. We are running 2.0.51 software. All our other cards are rev .49 and .53, none of which seem to be having this problem. Has anyone else seen this? Is there a cure? I can swap out these three cards with spares, but I have these and another 6 cards (in a new, as of yet unused chassis) at that rev, throwing them out isn't an option. thx, -- Aaron Nabil - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
