Purpose

On the international level, point codes (PC) are structured according to the ITU-T standards.  14 bits of information formatted as:

•   3 bits - Zone
•   8 bits - Area/Network
•   3 bits - Network-Signalling Point

On the national level, the point codes are formatted according to whatever standard the country chooses to use.  Most countries use either the ITU-T or ANSI national standards.

The ANSI point code is 24 bits of information formatted as:

•   8 bits - Network
•   8 bits - Cluster
•   8 bits - Member

The ITU-T national point code is 14 bits of information interpreted as a single identifier:

•   14 bits - Structureless point code

Quite often, in protocol analyzers for example, other formats are used.  Two other commonly used representations are:

•   decimal - all bits as a single decimal number
•   hexidecimal - all bits as a single hexidecimal number

This document provides a javascript point code converter tool to easily compute between the different standards and point code styles.
