Buying Guide

Match pair count to your PBX

Most small to medium systems use 25-pair cables for a single trunk block; confirm your punchdown or RJ21 block requirements before buying

Choose the right conductor type

Solid 24AWG copper conductors offer lower resistance and better longevity for fixed PBX runs compared with stranded alternatives

Verify connector orientation and type

Check whether your equipment expects a straight or 90° 50-pin RJ21 plug to avoid awkward routing or adapter needs

Prefer Cat3 for legacy voice lines

Cat3-rated 25-pair cable is standard for analog and low-speed digital voice; it balances cost and adequate performance for PBX signaling

Consider cable length and installation

Measure end-to-end distances and add slack for terminations; choose pre-terminated lengths that minimize field terminations when possible
