Ethernet LAN Termination
For proper operation, each end of the primary and redundant BTS
Ethernet Local Area Networks (LAN) must be terminated with a
50–ohm load. For a BTS consisting of a stand–alone or an expansion
frame, this is done by placing 50–ohm triaxial terminations on the LAN
A and B external IN and OUT connectors.
Check the LAN A and B external IN and OUT connectors on the I/O
plate of each frame (see Figure 2-3) and be sure terminations are
installed on all the uncabled external LAN connectors.
