I have a problem XOT.
Xot - CCL when configuring the connection was fine.
However, CCL was down for 2 weeks.
CCL operate after the connection has not been ordered XoT.
CCL has a serial port connection, the router did not came out.
Router that is connected in the Street was PVC.
Finally reboot the router and then connect it again became the CCL.
What's the problem?
