Numbering with Blocks
Fig. 3.65:
Numbering with blocks (shared numbering plan)
Each system is assigned one (or more) number ranges. For example:
• System 1: Number range 200.0.299
• System 2: Number range 300.0.399
• System 3: Number range 400...499
With this method all the systems in the same region can be reached under the
same regional prefix, which is why subscribers no longer have to dial it.
