Underground RUS cable supports how many conductor pairs?

Underground RUS cable is designed to carry many individual voice circuits in a single jacket. The number of conductor pairs in these cables varies widely because they’re made to serve different network sizes—from small rural setups to large distribution areas. In practice, underground RUS telephone cables come in multi-pair configurations spanning roughly twenty-five up to several thousand pairs, with a common range of 25 to 4200 pairs. This broad range lets a single cable meet the capacity needs of a network without requiring many separate cables or splices, which is why this range best fits the concept. Smaller, 1–2 or 2–5 pair cables aren’t typical for underground RUS multi-pair use, and an extremely broad figure like 6–3000 pairs doesn’t capture the standard family as well as 25–4200 pairs does.
