I have a router 2600 with two links, 1024K and E1 speed both works fine, my problem is that I have a new router 2801 and when I migrated the E1 interface on this router doesn´t work, on the console port I received messages %LINEPROTO-5-UPDOWN , Up an d Down, The firt probe was tested the two interfaces with link of 1024k,and both interfaces works fine, but If I conected E1 interface on any interfaces on 2800 fails. DCE device is a ONS 150E TyLink model. Both router using WIC 1T card
