Study Notes

A demarcation point (dmarc) is a physical location where a wide area network (WAN) provider's network connects to a client's internal network.
The dmarc could be a box provided by an internet service provider (ISP) and located at a customer's home.
In companies, the dmarc is usually a specific location inside the building.
The location of the dmarc is important for troubleshooting network issues, as problems on the provider side or the customer side can be distinguished.
Customer premises equipment (CPE) refers to the client's own equipment, such as routers, which are connected to the network on the customer side of the dmarc.
The provider may use specialized equipment, such as a smartjack or Network Interface Unit (NIU), at the dmarc location for remote troubleshooting.
The smartjack is a more advanced system that provides monitoring and diagnostics, allowing the provider to determine if issues are on their side or the client's side.
The client may not have physical access to the smartjack but can view it through windows and see alarm notifications and status lights for connectivity information.
