Ethernet LAN Termination
For proper operation, each end of the Primary and Redundant BTS
Ethernet Local Area Networks (LANs) 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 Tri–axial Terminators 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
Panel of each BTS Frame. Refer to Figure 2-3. Ensure terminators are
installed on all the uncabled External LAN Connectors.
