After upgrading bandwidth from 128 Kbps to 256 Kbps, serial interface showing "Serial0 is up, line protocol is down" , is there any chance of issue with Framing config mismach or what all possibilities can be.
Kindly help me out to resolve the same issue....

Hi Rajesh,
I assume your topology is something like this:
router ---- Telco CSU/DSU ----- Telco network/Internet
If the Telco increased just the bandwidth, I would expect that they didn't change the framing...
What is your original configuration and what did you change after the upgrade?
