Hello all,

What is the reason for change interface state?
And sometimes the router hanging and disconnect with E1 sites, then I must do reload the Router.

Start with physical layer and check cable. You then want to make sure the line settings and config match on both sides. If the other side is a provider, you will need to work with them to confirm. Other final things you can try is trying different E1 port/module, or software upgrade.
