If you are not yet connected to the fiber, it is preferable to wait until the installation of fiber is effective in your business before proceeding with the installation of the Service Line Pro.

Once you have made an appointment for the installation of fiber, it will be necessary to make a second appointment for the installation of the product. The Service Line Pro requires technical expertise, and therefore a second technician will need to come to your building to perform the installation.
