Crosspoint converter

Converts a serial number for Crosspoint systems, and back.

What the Crosspoint format is for

Crosspoint systems expect a badge number whose 24 least significant bits are rearranged according to a fixed permutation. The converter applies this permutation to the number entered, as well as the reverse operation to recover the original number.

The calculation is done in your browser: no number is sent to a server. Always check the result with a known badge before a roll-out.
