This was a wiring job I recently did for a new office renovation. I worked with AT&T to bring dedicated fiber internet access with POTS lines for the phones. (They needed POTS lines as they intended to bring over their existing phone
system.) There are 5 offices, a conference room and a common area and I brought 3 cable runs to each of them.
Hard to see but all wire is pulled through bridal rings, making future upgrades much easier. Be good to your future self (or the next poor schmuck tasked with fixing it).
Ethernet makes for good phone line so I was able to use it with their existing phone system. Later we can easily upgrade them to a VOIP phone system where the phones are powered over the ethernet wire (POE) and they won’t need to daisy-chain the VOIP phones to their computers because of all of the extra ports they’ll have in their offices. It’s also nice to have all of the ethernet wire CAT6 rated as opposed to CAT5 or CAT5e. Building wiring is rarely touched so when it’s used for technology, you want to future-proof it. CAT6 is may be more than what they need now but it will be ready for the increased demand for bandwidth in tomorrow’s technology.
I was very happy with how this turned out.
