I'm working on an issue that maybe someone else on the list has come across regarding ds0 service states. I might have even posted a question similar to this a long time back. Basically on some Hiper DSP's I'm getting some ds0's that are NOT in a "inService" state. It varies on which state they'll be in. Some are in maintenance mode, some are local out of service and others are remote out of service. And of course some are working properly and taking calls. If I busy the ds0's out (either soft or hard) and then restore them, they will come back to a normal "inService" state temporarily, and then eventually go back to one of the out of service states. I have more then 1 chassis at this site and it appears (have not thoroughly verified yet) that these issues do not occur on all the chassis. Infact it appears that possibly the only thing in common is that the cards that are experiencing this terminate into the same muxed DS3. The telco has no clue and is looking to me for answers. Anyone have any experience with this type of issue and could possibly offer some suggestions? Thanks in advance, Todd
