Hello,
As currently preparing for CompTIA Network +, I was watching the episode which discussed various WAN Technologies.
I have a doubt about DSH (Digital Signal Hierarchy).
When we subscribe to DS plans where they promise to give us a fixed, constant and a dedicated speed/bandwidth of connection, is that because of a seperate wire that runs into our house which ISP brings via configuring the router for the first time?
This photo is of the router that is there in my home. That Grey with RJ-45 jack, do we get fixed bandwidth/speed because of that wire or is it because of something else?
Because in Cable Broadband, bandwidth is shared right?
I'm just a little confused here. Does Cable Broadband is the same as that of a Set Top Box?
Also does that Grey Wire which comes in our house runs over electric poles like that shown in the pic below?
Thanks.

Hey @Atharva-Bet another good question, you most likely have a cable connection(I am not sure however) to your home which is a shared bandwidth. The DSH is a channelized signal multiplexing technology that businesses use to have a predictable dedicated bandwidth that can be purchased in fractions up to the maximum offered by the providers network. These are rarely used in home environments and require expensive dedicated hardware.

Usually, a cable connection to your service provider will be a coaxial cable connecting to the cable modem.
I think you mentioned you have a DSL connection. They are providing you a guaranteed service level. This can be DSL or cable depending on your service provider.
The grey wire to your house from the outside maybe outdoor and weather rated phone cable designed to have a think outer jacket so it's weather resistant and stops rodents from chewing through the cable as well.
