Overview

Baluns are miniature adapters for connecting mixed cable types or devices with mis-matched interfaces. They enable carrier and large-enterprise customers to standardize on twisted-pair wiring, even though some equipment may have unique E1 terminations (see diagrams below).

The Model 465 has the 1.6/5.6 coax connectors used extensively in telephone exchange sites. The balun has two interfaces, so both the TX and RX coax signals can be carried over a single length of twisted-pair cabling (which is much less costly than any kind of coaxial cable).
