Demarc Extension Services

Cascade Communication Services provides professional demarc extension services to help your organization get connected quickly and reliably.

A demarc extension connects your organization’s internal network to a telecommunications service—such as T1, DSL, or POTS—provided by a phone company or other vendor. The demarcation point (or “demarc”) is where the provider’s service ends and your responsibility begins. To integrate this service with your network, cabling must be extended from the demarc to your building’s wiring closet or data distribution system.

Demarc extensions vary based on building layout and infrastructure needs. At Cascade Communication Services, we have extensive experience installing demarc extensions in a wide range of industries, including offices, warehouses, schools, and shopping centers.

From basic demarc extensions to full-scale network integrations, our services are tailored to fit your organization’s specific needs. Here are some examples of our most common services:

Simple Demarc Extensions

We run cable from the Minimum Point of Entry (MPOE) or Telco Closet to an equipment room or the Main Distribution Frame (MDF). Cables are tested and neatly labeled. Once we have extended the demarc to a wiring closet, your IT department can take over for the rest of the network.

Horizontal & Backbone Distribution Systems

Cascade Communications can take a demarc extension a step further and install a distribution system for a network. For larger networks, it is often necessary to create structured-cabling solutions. 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. We can design both a horizontal distribution system (to connect the IDF to individual workstations) or a backbone distribution system that utilizes multiple vertical distributions.
