Various standardized numbers have also been created for special services, for
example, area code 800 for toll-free service, and 911 for emergency service.
A special numbering plan is also used within the MERLIN LEGEND
Communications System to identify individual telephones, adjuncts (for example,
fax machines), trunks, and other features and aspects of the system. Depending
on the number of extensions and the needs of your company, you can choose
from three different numbering plans that allow 2-digit numbers, 3-digit numbers,
or customizable variable-length numbers, respectively.
