Product Description
Network Interface Device (NID) is a physical device that is used for the interconnection of Inside Wire (IW) not owned or controlled by CenturyLink™ to CenturyLink's distribution network. The NID includes any means of interconnection of customer premises wiring to CenturyLink's distribution plant, such as a cross-connect device used for that purpose.
When located at the Minimum Point of Entry (MPOE), the NID contains terminations and a protective ground connection that protects the end-user's IW against lightning and other high voltage surges. These protective ground connections are also referred to as "protection", "protector blocks", or the "protector field". The NID is capable of terminating media such as twisted pair cable. When accessing a NID located beyond the MPOE, you may connect to the customer premises wiring without restriction from CenturyLink. When CenturyLink owns the intra-building cable beyond the MPOE, you may interconnect at the MPOE using the Multi-Tenant Environment-Point of Interconnection (MTE-POI) process and the Sub-Loop Intra Building Cable (IBC) product.
There are three standard configurations for NID deployment:
- Simple NID - Simple NID's are available as modular or non- modular
units. The modular NID is divided into two components, one containing
the over-voltage unit (protector) and the other containing the
end-user's IW termination with a modular plug which connects the
IW to the distribution plant or dial tone source. The non-modular
NID is a protector block with the IW terminated directly on the
distribution facilities.
- Smart NID - A Smart NID is a terminating and protecting device
that permits you to isolate the CenturyLink Sub-Loop facility from the
IW for testing purposes, and may have additional features that
not currently used by CenturyLink. If deployed in the CenturyLink network,
CenturyLink will make the same features and functions available to you.
- Multi-Tenant Environment (MTE) NID - The MTE NID is divided into two components: one containing the over-voltage unit (protector) and the other containing the terminations of the IW. The MTE NID may be located externally or internally to the premises served. Requests to move the MTE-NID must be authorized by the building owner or their authorized agent.
There are two kinds of NID offerings:
- Unbundled NID
- When you elect to use CenturyLink's NID features to terminate your facilities, you will order the Unbundled NID.
- An Unbundled NID is a CenturyLink owned NID that you may wish to access for the purpose of terminating your facility. CenturyLink will allow you to use all features and functions of the CenturyLink NID, including any protection mechanisms, test capabilities, and any other capabilities now existing or as they may exist in the future.
- Pursuant to generally acceptable work practices, and provided IW re-termination is required to meet service requirements of either your or CenturyLink's end-user, you or CenturyLink may remove the inside wire from the NID and connect that wire to your or CenturyLink's NID.
- Stand-Alone NID
- This offering is for the purchase and installation of a NID to be owned and maintained by the CLEC. Three configuration types are available. The configuration types are Simple, Smart and MTE. At your request CenturyLink will install a stand alone NID at your designated premises.
- Once you have issued an order for a Stand-Alone NID, CenturyLink will dispatch to the designated location and install the NID. CenturyLink will bill you a time and material charge to install the NID and following the installation the NID becomes your inventoried property.
- The Stand-Alone NID allows you to terminate your Loop facilities to premises IW. Additionally, if you elect to deploy your own NID, you may connect your NID to the CenturyLink NID by placing a cross-connect between the two. When you are ready to connect your Stand-Alone NID to the CenturyLink NID and you wish to have CenturyLink perform this connection, you must submit an LSR via IIS.
If a standard Unbundled Network Element (UNE) includes a NID (e.g., and unbundled local loop), when you order the UNE, there is no need to separately identify or order the NID. You will automatically receive access to the NID, and all features and functions, at no additional charge.

Availability
The NID is available where facilities exist throughout CenturyLink QC.
Terms and Conditions
In an MTE, you must first determine who owns and controls the IW. If CenturyLink owns and controls the IW then you will need to establish an MTE-POI and order the appropriate Sub-Loop which will include the NID.
If the building owner or end user customer owns and controls the IW then the following provisions which will include the NID.
You can use the existing CenturyLink NID to terminate your drop or cable if space permits, otherwise a new NID or other technically feasible interconnection point is required. If you install your own NID, you may connect your NID to the CenturyLink NID by placing a cross-connect between the two. When you provision a NID to NID connection, you will isolate the CenturyLink facility in the NID by unplugging the modular unit. If you require a non-modular unit to be replaced with a modular NID, CenturyLink will perform the replacement for the charge described in your Interconnection Agreement. If you are a Facility Based provider providing your own NID, the CenturyLink facility currently in place, including the NID, will remain in place. At no time should you remove the CenturyLink Loop facilities from the CenturyLink NID.
CenturyLink will allow you to connect your Loops directly to the CenturyLink NID field containing the terminations of the IW not owned or controlled by CenturyLink. Where CenturyLink does not own or control the IW, you and the owner of the premises shall determine the procedures for access to the CenturyLink NID.
Pursuant to generally acceptable work practices, and provided IW re-termination is needed to meet service requirements of either your or CenturyLink's end-user, you or CenturyLink may remove the inside wire from the NID and connect that wire to your NID or CenturyLink's NID.
You may enter the subscriber access chamber or end user's side of dual chamber NID enclosures for the purpose of NID to NID connections.
When you access a CenturyLink NID, or if you physically connect your NID (or equivalent) to the CenturyLink NID and make cross-connections necessary to provide service, you should employ generally accepted best engineering practices and comply with industry standards. At MTE NIDs, you will clearly label the cross-connect wires you use to provide service. See CenturyLink's Standard MTE Terminal Access Protocol for detailed information. CenturyLink will label its terminals when a technician is dispatched for work at the MTE NID. CenturyLink will not dispatch a technician for the sole purpose of labeling an MTE NID.
All services connected through a protector field in a CenturyLink NID and located inside a building will interface on an industry standard termination block. It will then extend, via a cross connection, to the premises IW. All services that are connected through a protector field in a CenturyLink NID and that are attached to a building will interface on industry standard lugs or a binding post type of termination. It will then extend, via a cross connection, to the end-user's premises IW.
At your request, CenturyLink will allow you to connect your facility directly to the protector field at a CenturyLink NID that has unused protectors, and that are not used by CenturyLink or any other Telecommunications provider to provide service to the premises. If you access the CenturyLink protector field, you will access the distribution side of the protector field only where spare protector capacity exists. In such cases, you will only access a CenturyLink NID protector field in cable increments appropriate to the NID. If 25 or more metallic cable pairs are simultaneously terminated at the MTE NID, additions must be in increments of 25 metallic pairs. In all cases, telecommunications cables entering a CenturyLink NID must be terminated in compliance with Federal Communications Commission (FCC) 88-57, section 315 of the National Electric Safety Code and section 800.30 of the National Electric Code. Other types of Protector Field access may be available. Refer to your Interconnection Agreement for further information.
After determination of ownership of intra-building cable, which is obtained by submitting a MTE Point of Termination Form to CenturyLink, you will need to complete and submit the CLEC Access at CenturyLink Protector Field Application to request access at the protector splice or access to the protector field.
