This is a list of rules for TIF NS:
1.
An arbitrary number of DN and DN Blocks can number substitute to the same DN. This DN, called
the NSDN, cannot substitute to anybody. The only exception is called a subscriber pair.
2.
Subscriber pair: Two DNs that number substitute to each other. Nobody else can number substitute
to either DN in this pair.
3.
DN Blocks can number substitute to a DN. However, nobody can number substitute to a DN Block.
4.
The default subscriber type is public. If subscriber type st has never been explicitly set on a record,
the record is public.
5.
Only DN and DN Blocks with the public subscriber type can be linked to a private DN through
TIF NS. Likewise, only private DN and DN Blocks can linked to a public DN.
6.
Subscriber type is set when the NSDN is defined and TIF NS is created. It cannot be changed while
the TIF NS relationship persists.
7.
There are two ways a DN or DN Block can be removed from TIF NS.
• Directly, if it has an NSDN. It may be updated with ‘nsdn none’. This is to be performed on
each DN in the case of a subscriber pair.
• Indirectly, if it does not have an NSDN. All the DN and DN Blocks that substitute to it have
been updated with ‘nsdn none’.
8.
A DN cannot be deleted while other records refer to it by TIF NS.
9.
A DN or DN Block with NSDN is limited to having one NE (sp, rn, vms, grn).
10.
A DN or DN Block with two NE (sp, rn, vms, grn) and ASD, cannot have NSDN. They cannot
substitute to another number.
