The Two-Digit numbering plan is the factory setting. This plan is designed for
systems with fewer than 50 stations at businesses that do not anticipate a need
for more than 50 stations in the next one or two years.
Figure 2-19 shows the numbers automatically assigned by the system.
Two-Digit Numbering Plan
The numbers in the figure are arranged in blocks according to the first digit. The
type of equipment, jack, or feature to which they are assigned is indicated in the
block.
Each of the first 58 station jacks is assigned a 2-digit extension number
beginning with 10 and ending with 67. The rest of the stations (68-144) are
assigned 4-digit extension numbers 6800-6885. Extra adjuncts are assigned as
extensions 6900-6985.
