[c-nsp] VWIC-2MFT-E1, Serial Up/Down problems in Cisco2611XM

[Oliver Boehmer (oboehmer)]

Hi Ganbold,

the error message "E1T1_MODULE-3-LINEFLAP: Interface Serial0/2:0
receiving 
excessive error" says why the router takes down the line. Take a look at
the errors in "show controller e1" (or "show controller t1" if you use
T1) and check them. This could either be a telco issue or a clocking
issue.
