Lost MDD Timeout? MDD Message timeout ?
Hey people i keep getting these on my logs T202.0 Lost MDD Timeout.. and T203.0 MDD message timeout any idea on why thats happens... Happens when i reboot my modem and i lock onto 783 Hz and takes a long time to boot up, when i lock onto 729 Hz these logs wont show up and my modem boots up normal???
That's a pretty common message, it's more of an informative note in the log than a warning. The MDD (Mac Domain Descriptor) is transmitted every two seconds on the downstream channels, and part of the process involves fragmenting the MDD if it's large. The MDDs often get dropped, and if too many of them are dropped, the modem's MDD timer expires and it begins looking for them again.
What may be happening is that one of the DS channels that Charter is using is not in the same fiber node, or not set up as a primary channel, and when the modem tries to lock onto that channel (783 for example), there is no MDD being transmitted (or an improper one) and the MDD timer expires and the modem moves on and searches for an MDD on the next available downstream.
Thanks you were alot of help..
