Demarc Extensions

What Are Demarc Extensions?

Demarc extensions are when a technician installs or activates the wiring that runs from the demarcation point to the tenant’s network room. This process occurs when organizations need new communication services or want to make upgrades to their existing services or OSP.

Types of Demarc Extensions

Types of Demarc Extensions

Demarc extensions can vary from simple to complex depending on the organization’s specific communication needs. A simple demarc extension would involve running wiring from the telco closet to an enterprise business’s equipment room, while more advanced projects may involve expert project management and support testing and turning up new circuits to ensure they’re working properly.

Securing a Demarc Space

Securing a Demarc Space

The demarc point is where an enterprise business houses its most important connectivity point. A network outage can potentially result in your organization losing thousands of dollars in revenue, so securing and maintaining it effectively is critical. 

Ensure only authorized users are able to access your demarc point. Keep all critical infrastructure in a secured, closed area and make a record of all personnel who access the space. When specialized work is needed, such as demarc extensions, only outsource work to a reliable, experienced technician.


Frequently Asked Questions

Our experts answered the most common questions we hear about demarc extensions.

Can TailWind help me extend my fiber circuits into the building from where the carrier drops the services?

Yes, TailWind can complete any fiber extensions, trenching, or other tasks needed to bring the service from the services carrier’s drop point to your preferred endpoint.

Can Tailwind run cables throughout my office or retail space?
Absolutely! TailWind will send a low-voltage technician to your site to determine the costs based on your needs for the specific location.
What is a demarcation point?
A demarcation point, often referred to as a demarc point or demarc, is the physical point where the public switched telephone network (PSTN) ends and an organization’s telecommunications network begins. For example, if a building’s demarc point is located on the ground floor and the business needs to connect offices on the 10th floor to the network, a technician will need to extend the demarc point to the private network several floors above.
What are the 3 main types of demarcs?

The three main types of demarc points for enterprise businesses include: 

  • Network Interface Devices - NIDs are the most basic and common type of demarc. They are weatherproof, non-digital boxes regulated by the FCC. The boxes serve as surge protectors and contain a test jack, wiring termination, and circuit protection.
  • Smartjacks - Smartjacks are also commonly referred to as intelligent NIDs or INIDs. They use a circuit board to strengthen the signal, and unlike basic NIDs, they don’t require tenants to run a DSL through their buildings.
  • Optical Network Terminals - ONTs use fiber optic cables to provide a faster, stronger signal. They use power provided by an external source and often come with backup batteries if a power failure occurs.
How much does a demarc extension usually cost?
As with many network services, the cost of demarc extensions will vary depending on how far your location is in relation to the demarcation point. Generally, extension costs begin at $300 for a small business and can be completed in one day.
