It works with balanced or unbalanced G.703 equipment. Unbalanced interfaces use only one tran***it, one receive, and one ground lead in contrast to balanced interfaces, which use a pair of tran***it and receive leads.
The RackNest 2/14 has a snap-type terminal block for the line interface and a 25-pin connector for a digital interface.

You can hot-swap power supplies during operation with no effect on the modems and their data tran***ission. th 2- or 4-wire twisted-pair cable.
