The right-hand panel (three columns of black jacks) is for combining various phones lines into combinations to be sent out on given Cat5 cables. The data sheet is pretty interesting for someone like myself with primarily RJ45/8P8C/Ethernet/whatever experience. In fact, ASO from the model number means Advanced Small Office. It appears that this was quite the powerful thing for a premise with multiple phone lines.typically a small office. You have a Leviton Distribution Panel, 47606-ASO: I guess no one actually looked at the picture and instead rapidly dived into debating loosely relevant things. Wired will always out perform wireless, regardless of how much bandwidth the wireless is capable of. If you are near a wireless network that is using the same channel as you, your devices are also competing with devices on that other network for air time. Now multiply that by the number of devices on your network. Device: Hey access point, are you still there? Access Point: Yep, still here. Once joined, the device will call out to the access point every few seconds. When a wireless device comes on the network, it must join an access point. Wireless also has a lot of extra traffic over a switch due to control traffic. But we also have the added interference from nearby wireless networks from your neighbors, hotspots, some TV and streaming device radios, the wifi toaster, etc. So now we start having higher latency due to wait times, collisions, and re-transmits. All the devices can hear all the others, but only one can transmit at a time. Latency goes down because there can now be multiple conversation going on at the same time. So if device1 needs to talk to device2, that traffic does not interfere with the conversation between device3 and device4. Switches know what device is on what port. This caused both computers to stop talking and wait a period of time and try again. There was also a lot of collisions, which is when more than one computer tried to talk at the same time. Bandwidth stayed the same but latency went up due to wait times. Since only one computer at a time can talk, everyone else had to wait until the line was clear before they could talk. A packet came in one port and was repeated on all the other ports. In the early days we used hubs where all the computers plugged into the switch. The job will get done faster with the wheelbarrow because there is more capacity per trip. The wheelbarrow holds more than the bucket, that is the bandwidth. You walk at the same pace while carrying a bucket or pushing a wheelbarrow. You can either use a 5 gallon bucket or a wheelbarrow to move the dirt to the garden. Let's say you are building a garden in the back yard and have two yards of dirt delivered to your driveway. Latency is how long it take to get from here to there. Speed is a combination of latency and bandwidth. Bear with me a bit while I talk about some networking concepts and history.
