Demarc Extension Services

INC Installs can help get your organization online by providing a demarc extension, a routine service needed by many businesses. With INC’s national installation network, we can perform demarc extensions nationwide at multiple jobs at locations across the country or at a single location of your choice.

A demarc extension is the process of connecting your organization’s network to a data line–such as a T1, DSL, or POTS–provided by the telephone company or another vendor. The “demarcation point” (or “demarc” for short) is the spot at your location where the vendor terminates their circuit. Beyond this point it is your responsibility to connect your network to that demarcation point. The demarc cabling must be extended to reach a wiring closet or some sort of data distribution system in order to integrate with your network. Depending on your needs and the layout of the site, services for a circuit extension can vary greatly. INC has experience performing demarc extensions in many environments, including warehouses, offices, schools, shopping malls, and high-rise buildings.

INC can provide a simple extension for your IT department to work with or a full-service network integration. Our solutions are always custom-tailored to the needs of our clients. Here are some examples of our most common services:

Simple Demarc Extensions

INC runs cable (typically UTP Cat5e) from the Minimum Point of Entry (MPOE) or Telco Closet to an equipment room or the Main Distribution Frame (MDF). Cable runs are neatly arranged and concealed as much as possible with mounting hardware provided by INC. Cables are tested and neatly labeled. Once INC has extended the demarc to a wiring closet, your IT department can take over for the rest of the network.

Horizontal and Backbone Distribution Systems

INC can take a demarc extension a step further and install a distribution system for a network. It is often necessary to create structured-cabling solutions for larger networks. Our technicians can connect the Main Distribution Frame (MDF) to Intermediate Data Frames (IDF) using either 4-pair, 25-pair, 50-pair, 100-pair, 200-pair, or fiber optic cable. INC can design both a horizontal distribution system (to connect the IDF to individual workstations) or a backbone distribution system that utilizes multiple vertical distributions, such as a in a high-rise building or a particularly long hall.

Test and Turn Up Circuits

When a customer purchases a new dedicated-circuit T1 line, the vendor will provide a start date on which the circuit goes live. Test signals are then sent to ensure proper communication. INC has extensive experience in working with telephone companies from the client’s side in order to make sure your new circuit is working properly.

Pre-Configured Router Installation

For certain applications, a client may need the installation of a router configured to receive data from a certain source. INC can readily incorporate the installation of such a router with a demarc extension.

What is a demarcation point?
The demarcation point is the electrical spot where your service providers cabling meets your on-premises wiring. The spot dictates who is responsible for installation or maintenance of the cabling or hardware. For example if the problem happens downstream from the demarc, then it is the responsibility of inside wiring to fix the problem. If it happens upstream, it is the service providers problem.

What is the MPOE or minimum point of entry?
The MPOE is the physical spot where the service providers delivers their services in a building. It can be at the telco closet, but doesn’t always have to be at the telco closet.

Where can I find the demarcation point?
The demarcation point maybe inside in a shared telco closet (MDF) or it maybe on the outside of the building in a weatherproof box. You must locate the network interface device (NID) or smartjack. The smartjack is an advanced version of a NID known as an intelligent network interface device and provides diagnostic insight to the service provider.
