Pair Gain, what is it?
Pair Gain is a term used by Telstra to describe technologies that are used to generate extra telephone services in areas where there are not enough copper pairs to provide everyone with the services that they require. Please note that Telstra refers to RIMs as “Large Pair Gain” whilst the technologies covered in this section are normally referred to as small or medium pair gain systems. Pair Gains works when it typically takes one or more phone lines and provides more subscriber services than there are actually lines.
