I have a cisco 1841 with a t1 wic. the isp confirmed that it went down today but said it came up around 9:30 am. things did come back up but they have been horrible ever since, slow, cant connect often, etc. here is a post of my sho int s0/0/0. as you will see i have a bunch of crc output on the serial interface. i dont see where the clock source is. any help is appreciated.
