Network Interface Device

Why Verizon?

Verizon takes it commitment to provide unbundled elements to CLECs seriously. For quality and reliability, when you need unbundled network elements, trust Verizon.

A NID (Network Interface Device) is the point of demarcation between the Unbundled Network Element (UNE) loop and the end user's inside wire. NID access enables a Local Service Provider (LSP) to be connected to the Verizon NID to provide a connection to a LSP's end user's inside wire.

The NID, as a UNE, is offered as a Verizon NID to LSP NID arrangement. The NID provides a facilities-based LSP the connection of its NID and the wiring of a Verizon NID (NID to NID) for the purpose of accessing the end user's inside wire (see diagram section under Technical Specs).

This arrangement provides access to a Verizon-owned NID for use by the Local Service Provider (LSP)  in provisioning its loop services. For a Verizon NID to LSP NID arrangement, Verizon dispatches a technician to remove the jumper wires that connect the Verizon network protector chamber to the end user chamber in the Verizon NID housing. The technician then runs a jumper wire from the end user chamber of the Verizon NID housing to the LSP NID. The LSP's technician can also run the jumpers from the Verizon NID in the customer side of the NID housing to the LSP's NID.

In the case of a non-modern NID housing (a NID housing without separate network protector and customer NID chambers), a Verizon technician would be dispatched to establish a new modern NID housing (a NID housing with separate chambers). The Verizon technician could then run a jumper wire from the NID in the end user chamber of the Verizon housing to the LSP NID. The LSP technician could also run the jumper after the Verizon technician has installed the modern NID housing.

In the case of a multi-tenant building, with landlord-owned House & Riser, the NID would be the punch blocks (board) that make up the cross-connection facility, usually located in the basement. The F1 facility provider, either Verizon or the LSP, performs the cross-connect to the landlord-owned House & Riser.

In the case of a multi-tenant building with Verizon-owned House & Riser, the LSP would need to subscribe to Verizon House & Riser Service if the LSP could not position its own facilities at the end user's premise (apartment). Pending an effective FCC order, House & Riser service is currently only available in New York.


Non-recurring charges are billed on a time and materials basis to cover the costs when a Verizon technician is used to connect the Verizon NID to the CLEC NID or install a new NID housing. One Universal Service Order Code (USOC) identifies access to a Verizon NID in a Verizon NID to CLEC NID service arrangement. A “TC Not Ready” charge is assessed if, upon dispatch of a Verizon technician to establish a NID to NID arrangement, the CLEC NID is not prepositioned and ready for use, or if the Verizon technician cannot gain access to the end user's premise. Recurring rates for both the 2- and 4-wire NIDs apply.

Pricing and applicable USOCs may vary by state jurisdiction and pursuant to individual carrier interconnection agreements. See your federal and state tariffs for detailed information.
