The Tower will have a sensible and easy to distinguish numbering system. However, it would provide for a number of wasted numbers. Essentially, from the range 07-42, there will be some numbers that would be used, but most of them will be empty. I will address those in a little bit. For the Tower, each apartment will have the subscriber number that is their apartment number. The SRo?s will have a preceding 0 in front of their apartment number as the subscriber number. Therefore, 701 will have the subscriber number of 0701
Apartments of just a few units, or those under 20 will get a partial bloc of numbers. In example, block 10 will have 01-20 already taken, but 1021-1040 can be used for a 20 unit apartment building. This will not make sense when compared to the apartment number, but it would fill up those numbers that would otherwise be wasted. This will start to fill up those numbers that would have been reserved for the apartment building, but would have otherwise not be available when doing things in a conventional way.
Buildings with more than 80 units will get a block of numbers. One example might be 00 to where a tenant’s number might be 0001-0080. This will take up most of a block, but will make sense for the perspective of distributing numbers around. While these numbers will not coordinate with the apartment number like the Tower, it will be a way to provide a telephone number to an apartment, and possibly include telephone services for the tenants that may not otherwise have a stable telephone services. Each building will have an fsp-sip SSID?, and each apartment’s phone will connect to this SSID. This will mean the phone will work as long as the buildings internet service is active. If the only way they receive email is through their phone, and that is good enough, then the tenant does not have to acquire an ISP? to make use of the phone line.
