Seth there are issues with downgrading Hiper DSP's off of v.92 code. The procedure is listed in the release notes for TCS 4.5. If you do not follow the procedure you will ruin your card and it will have to be repaired by Commworks. If you don't have the release notes use the following procedure. Downgrading Code You may find it necessary to revert back to Total Control 1000 Release 4.3 code on either the DSP multispan card or the HiPer DSP card. Follow these steps to revert back: 1 Flash to Total Control 1000 4.3 compatible code. (Previous versions are not usable until the card successfully loads/boots 3.1.x code.) 2 Before you upload the code you must log into the console, or telnet, and enter the following commands: chdev mdm1 at-re1 3 After the prompt returns, initiate the code download as usual and reboot when it is completed.

We've run into a busy signal problem with one of our cards after upgrading it. It didn't have this problem at 2.0.19, but it does at 3.5.12, so I'd like to downgrade to 2.0.19 and then work my way back up, if that's possible.

before sending it to repair try to upload the firmware again... sometimes it works...

I have a HiperDSP card in a TC chassis that appears to have failed over the weekend. The RN/FL light was red, and the FOURTH utilization bar LED from the bottom was AMBER. I moved the card to another slot, and it worked OK for 2 days, and failed again. I left the card unplugged overnight, and plugged it back into the same slot this morning. It is now working again. But obviously something is wrong.

I know that a red RN/FL is no good, but does the 4th utilization bar being amber mean anything? Any tests or settings I should check while the card is in an operational state?

Not ever having a DSL go bad on me, what is the best course of action -- attempt to have Commworks repair it, replace it with a used card, ??? Card is about 2.5 years old.

Thanks,

Scot
