Re: Verizon Public Notice of Network Change(s), 47 C.F.R. §§ 51.325 - 51.335 Copper Retirement ID No. 2019-03-A-MD

Dear Ms. Dortch:

Pursuant to Sections 51.325 – 51.335 of the Commission’s rules, Verizon hereby submits the attached: Certification of Public Notice of Network Change under rule 51.329(a); Public Notice of Copper Retirement under rule 51.333; and Certification of Public Notice of Copper Retirement under rule 51.333.

Specifically, Verizon is providing notification of the replacement of copper distribution and loop facilities with fiber-to-the-premises facilities at all remaining locations in the Aberdeen, Allentown, Annapolis, Arbutus, Armiger, Baden, Bel Air, Baltimore – Downtown, Edmondson, Frankford, Hamilton, Liberty, Madison, University, Wolfe, York Road, Bowie, Brooklyn, Brandywine, Bryans Road, Brunswick, Bradley, Wood Acres, Wildwood, Beltsville, Chase, Owen Brown, Snowden River-RSU, Berwyn, Clinton, Clarksville, Crofton, Central Avenue, Catonsville, Cockeysville, Hunt Valley, Damascus, Dundalk, Dorrs Corner, Edgewood, Elkridge, Parkway, Ellicott City, Essex, Fork, Friendship, Frederick, Chapel Hill, Galesville, New Glenwood, Germantown, Gaithersburg, Havre De Grace, Hagerstown, Chillum, Hyattsville, Riggs Road, Indian Head, Jarrettsville, Laurel, Landover, Lanham, La Plata, Lexington Park, Manor, Mayo, Marlboro, Muirkirk, Mount Airy, North Point, Odenton, Piney Orchard, Oakdale, Owings Mills, Oxon Hill, Parole, Pikesville, Parkville, Poolesville, Perry Hall, Montrose, Randallstown, Reisterstown, Colesville, Norbeck, Northwood, Silver Spring, Suitland, St. Margarets, Severna Park, Temple Hills, Church Road, Woodlawn, Waldorf, White Marsh, Wheaton, and Winters Run, MD wire centers. Upon completion, Verizon will provide services available over its fiber optic network.

The majority of customers served by copper at these locations purchase “plain old telephone service.” Following transition to fiber, Verizon will continue to offer these Marlene H. Dortch September 3, 2019 Page 2 of 2

customers the same POTS over fiber at the same price as they received on copper facilities, with no change in the underlying features and functionalities in their service.

There may be one or more obsolete, narrowband services (such as certain DS0 level services) that are incompatible with or unavailable over fiber. If so, we will work closely with those customers to address their particular needs.

Please contact me should you need any further information.

Sincerely,

All of Verizon’s copper retirement notices may be viewed on Verizon’s website at http://www.verizon.com/about/terms-conditions/network-disclosures

Description of the planned network change(s): Verizon intends to retire the copper facilities at all remaining locations in the ninety-seven (97) wire centers listed above. Verizon has deployed or plans to deploy its fiber-to-the-premises network in these areas and intends to provide services over a fiber network infrastructure. Updating our network from copper to fiber benefits our customers because of fiber’s resiliency and reliability, especially in inclement weather. Fiber also provides our customers with expanded capabilities to grow with current bandwidth demands for their home or business.

Description of reasonably foreseeable impact(s) of the planned change(s): After the retirement of the copper facilities, Verizon will: (1) no longer offer services over copper facilities; and (2) cease maintaining the copper facilities. To help ensure an orderly transition, Verizon may require customers and interconnecting entities to migrate services off of copper facilities well before the copper retirement implementation date.
