Demarc Extension Services

When your ISP or carrier delivers a new circuit (T1, POTS, DSL, fiber, Ethernet, or other data line), the job isn’t finished until it’s fully integrated into your internal network. That’s where LMC Cabling excels. We specialize in professional demarc extensions—extending the demarcation point (demarc) from the carrier’s termination point to your telecom room, server closet, or preferred distribution location—ensuring fast, reliable, and compliant connectivity.

Whether it’s a single-site upgrade or coordinating multiple locations across Texas (or beyond), our experienced team handles demarc extensions with precision, minimizing downtime and eliminating surprises.

What Is a Demarc Extension? The demarcation point is the official handoff where your service provider’s responsibility ends and yours begins. We bridge that gap by:

• Running high-quality cabling (copper, fiber, or coaxial) from the demarc to your internal wiring infrastructure
• Terminating and testing connections for optimal performance
• Integrating the circuit into your LAN, WAN, or voice/data systems

Environments We Serve We’ve successfully completed demarc extensions in diverse commercial settings, including:

• Corporate offices & high-rise buildings
• Warehouses & distribution centers
• Educational facilities (schools, universities, campuses)
• Retail stores, shopping malls & strip centers
• Industrial plants & manufacturing sites
• Healthcare facilities & multi-tenant buildings
