Nothing is more frustrating for T1 buyers than hidden costs that pop up during and after an installation. The kingpin of hidden costs is by far the dreaded DMARC Extension. Hidden costs regarding DMARC extension are often the result of multiple carriers coming together to deliver a service and poorly communicating with each other on what it will take to complete the job. Often, a clear view of what additional parts and pieces are needed to deploy a T1 isn't known until the eleventh hour when the LEC is installing the access loop, which is the last piece of a T1 install. The blame is often placed on the sales rep for not clearly defining these costs upfront, or the ISP for not putting these costs in the price quote. Finger pointing all around may occur, but in the end, the buyer will lay out additional dollars to keep the install moving forward. This article covers what an extended DMARC is, when it is needed, and what costs are associated with it should it happen on your T1 install.
