The infrastructure will need to be completely overhauled and standardize. Depending on the condition of the telephone network will depend on what needs to be done. At the very least, there will be hopes that all subscribers will have access to SDSL services with rollout of Fiber optic being for any future upgrades. This means the conventional copper telephone lines, and coaxial lines will be replaced with fiber optic which will also carry telephone communications. Inside the home, all telephone lines will be replaced with RJ45, and run to a communications closet. From there, the LAN will connect to a router or network server. That device will either plug into an RJ45 (WAN) where there’s fiber or Tx connections, and a modem for DSL and cable. DSL and cable will eventually be upgraded to fiber optic.
There will be two options for telephony communications. The first will be SIP/VOIP solutions for terristrial lines, and 4G+ for cellular lines. Since telephone is an essential service, the carrier(s) must provide an affordable option, and this will be based on what a single person will get from GBI as if that was the only income they have. All phones must have a slot and tray system for their SIM 1, and any SD card expansion capabilities. This is the kind of tray that needs a SIM eject tool. If there are dual SIM, the second SIM must be eSIM. These two requirements will make it almost impossible for any basic phone to qualify for NSC compliance.
For terrestrial lines, all POTS phones will be sought to be phased out. Any current phones left for sale will be sold out, but any new inventory must meet and comply with SIP standards. In addition, there will be ATAs that would be for sale. The phone will plug into the ATA, and the ATA will plug into the LAN connection. This will apply to POTS phones, fax machines and legacy elevators. As time goes on, the goal will be to have SIP only phones. When using an ATA, the subscriber can log into the ATA, and first thing they should do is change the admin password to reduce the chances of hacking. They will then enter the number as the UID, SIP Server will be sip.tel.ka, and the password will be found on the control panel of the telephone line. Any number ending in 0 will be a fax only line. If there will be no fax, then the last number will be 1-9.
For cellular, the carriers will no longer be able to sell basic or KaiOS phones. The reason is simple and that is the smartphone does so much more, and integral to the modern infrastructure that is to be rolled out into Kaldus. There are a number of reasons why, but the main reason is convenience for the subscriber. Especially if someone is living on a limited income, a smartphone will be able to function like a very basic computer to get their essential needs done including contact management, email, web browsing, and using various apps for the government, and companies they associate with. If someone has a computer, most basic phones will not function as a modem for a notebook PC, and therefore less functional. 2FA-Authenticator App is also only available on a smartphone.
