Demarc Extensions FAQs for San Antonio
Do you install Demarc Extensions across all parts of San Antonio?
Share the exact address and scope. We confirm qualified coverage, licensing, travel, and availability for the San Antonio project before scheduling.
What is the typical turnaround time for a Demarc Extensions quote in San Antonio?
We first review the address, plans, photos, access requirements, and requested schedule. A firm price is issued only after the scope is verified through sufficient documentation or a site survey.
What is a demarc extension?
A demarc (demarcation point) is where the telephone or internet service provider's wiring ends on a property (usually the MPOE in the basement or utility room). A demarc extension connects that carrier handoff to your company's server room.
Can you extend fiber optic carrier circuits?
Yes. We run armored single-mode fiber with SC/UPC or LC/APC terminations from the telco demarcation cabinet directly to your network firewall or SFP+ switch port.
