OctelNet addressing scheme design rules
When designing OctelNet addressing schemes, the following rules must
be observed.
n The mailbox length must be greater than or equal to 3 digits.
n The additional digits must be less than or equal to the mailbox
length.
n The number of digits in the prefix plus the additional digits must
be greater than or equal to the mailbox length.
n In multiple addressing schemes, no two prefixes can contain the
same first digits, if the sum of the additional digits and the
number of digits in the prefix is the same in each case. For more
information, see “Examples” on page 5-6.
Note: This rule applies to addressing schemes across all
OctelNet nodes in the organization.
