6. After connectivity has been re-established, reinstall network elements and variables that you
removed earlier (in Step 1 ).
7. If all the above-mentioned steps fail, then start the process of advanced troubleshooting as
described in the How to troubleshoot BTS? Section.
Troubleshooting a loss of Ethernet connectivity
When the CPE does not establish the Ethernet connectivity, perform the following steps to troubleshoot
the loss of Ethernet connectivity:
1. Verify that the connector crimps on the Ethernet cable are not loose.
2. Verify that the Ethernet cable is not damaged.
3. If the Ethernet cable connects the radio to a network interface card (NIC), verify that the cable is
pinned out as a straight-through cable.
