What is the cost of a demarc extension?

June 5th, 2018

This cost varies with the carrier. Some carriers do it by the hour, others have a pre-set fee. It could also depend on whether the T1 is already installed, or if it is requested before the install. The carrier will add more fees if the line is already installed, so be sure to specify where you want to "plug in" before your installation is scheduled.
