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.
