Loop Service "REQTYP" (requisition type) provided on the LSR is "AB".

In a Verizon FTTP (Fiber to the Premises) overlay area (where FTTP is built in parallel to the existing copper network), CLECs requesting a move from an existing FTTP based service to a UNE Loop where copper or other UNE facilities are available, will require a dispatch of a Verizon technician to install a Network Interface Device (NID) at the CLEC's customer's premises. When a CLEC determines that a line being moved is served on FTTP, an LSR requesting a new loop will be required. Once the new loop has been provisioned, a second LNP LSR can be submitted requesting the migration of the end user's telephone number, if desired.

Provide the correct Network Channel (NC), Network Channel Interfaces (NCI) and Secondary Network Channel Interface (SECNCI) codes. Services cannot be provisioned unless the correct NC/NCI codes are provided.
  • These codes identify the physical and electronic characteristics of the circuit and need to correspond with the "TOS" entered on the LSR.
  • NC/NCI and SECNCI codes are Telcordia standard and are located at, Telcordia Technologies, Inc.
  • Verizon Business Rules provides product specific codes.
Facilities are provided subject to the availability on a first-come first-serve basis in the requested central office. If facilities are not available when requested, the CLEC will be notified by a jeopardy report. In response to the jeopardy report, the CLEC may choose to cancel the order or postpone the date until facilities are available.

The Access Collocation Terminal (ACTL) is the 11th character of the CLLI code assigned to every collocation arrangement.
  • It is a required field for ordering a Loop Service.
  • The ACTL must be verified by the CLEC prior to issuing an order to determine if it is collocated in the end user's serving wire center.
  • The CLEC can verify the ACTL by checking the 11th character against the CLLI code assignments maintained in their records.
  • The first 8 characters of the CLLI code define the Verizon wire center in which the collocation arrangement exists.
  • Codes are Telcordia standard and are located at, Telcordia Technologies, Inc.
When requesting a new or move of a network interface device (NID), review Verizon's Business Rules for appropriate usage and values of the NIDR field.

When placing an order it is essential to format the circuit information correctly according to the specific Verizon Business Rules.

Provide Collocation in central office 48 hours prior to Loop Service being installed.

The term "Hot Cut" is used to describe the near-simultaneous disconnection of a Verizon working loop from a port on one carrier's switch, and the reconnection of that loop to a port on a different carrier's switch, without any significant out of service period. Additional ordering information can be found in the UNE Order Samples.

Service conversion times generally occur between 8:00 A.M. and 8:00 P.M Monday through Friday.
  • The time zone applies to the end user location.
  • Any scheduling after 8:00 P.M. requires additional negotiation and charges.
  • Premise visits are also required on the installation of new and additional Loop Services by a Verizon Technician.
  • Access information should be indicated on the service order.
If no access information is provided visits will be conducted between 8:00am-5:00pm

Common Language Circuit Identification (CLCI) is an industry standard method of assigning circuit numbers. There are two standard formats for circuit number identification, Serial Number and Telephone Number format. The Serial Number format should be used when the circuit cannot be immediately identified as a telephone number. The Telephone Number format will be used only on those circuits that are directly connected to dial tone.

The Voice Local Service Provider (LSP) and the Data LSP should use a different PON/Version number on the LSRs for Line Splitting orders.

The CLEC reports the intended use of the Subloop (i.e., voice, ADSL, 2-wire HDSL or 4-wire HDSL) on the appropriate fields of the LSR. The CLEC provides Verizon with the appropriate NC/NCI codes on the LSR. The NC/NCI codes can be found in the Verizon Business Rules.

Verizon Business Rules provide complete explanations of how to populate order forms with valid entries.

The Conversion of Special Access to Unbundled Loop process is located in the Conversion Guidelinespdf file.

CLEC to CLEC Migration -
In the Order process:
  • Submit an LSR using the "ACT" of "V" and the "LNA" of "V".
  • Directory Listings are not required. If the DL Form is used, the "Donor" CLEC is responsible for disconnecting the old listings. NOTE: If establishing a NON-PUB listing the change does not become effective until the "Donor" CLEC removes the old listing(s).
  • Multiple EATNs can be combined on one LSR under the following conditions:
    • Same Address
    • Same End User
Telecommunications Service Priority (TSP) is available to Business and Government end users. It is not valid on Residential Accounts. It is ordered by populating the "TSP" field with an authorization code. A TSP Authorization Code is assigned to the end user by the Office of Priority Telecommunications. A separate unique TSP Authorization Code is required for each service or circuit ID. Separate codes are required for each segment or location of a multi-point circuit. It is the responsibility of the end user to obtain the code and provide to their local service provider.

When disconnecting a Loop Account and retaining the directory listings as a separate Fictitious Listing, the account will be modified to be a Standalone Directory Listing account. To establish a Standalone Directory Listing please see Ordering Directory Services - Directory Listing.

Loop Share is a product where a VLEC purchases a UNE Loop from Verizon (DSL qualified), and uses the loop to provide voice traffic from the VLEC's voice switch (via a Co-location arrangement) and data traffic from the DLEC's data switch (via a Co-location arrangement). The following information is needed to order Loop Share:

  • For the "REQTYP" (requisition type), "ACT" (activity), "SLI" (sub-loop indicator) and "LNA" (line activity) for Loop Share see the chart below.

  • NC/NCI codes are Telcordia standard and are located at Telcordia Technologies, Inc.

  • The Loop Share is billed to the voice provider, who is considered to be "owner" of the DSL-capable UNE loop

  • The second character of the "TOS" (type of service) for Loop Share must be "F."

  • When migrating to Loop Share the existing DLEC must be the same for all circuits. Only the VLEC will be allowed to place the migration order. For migration from existing data, the VLEC will be prohibited from changing the "CFA" {Connecting Facility Assignment (SECLOC Details)} information. The "CFA" information is derived from the CSR.

  • The "APPTIME" (appointment time) is only valid for Line Share and Loop Share orders when inside work is requested at the end user's premises.

  • The voice CLEC and the data CLEC are responsible for maintaining a cross referenced list of the circuit ID (CLS format) associated with the Loop Sharing arrangement. This is important as either the voice or data provider may call in troubles on this shared loop.

  • The LSR will carry applicable USOC's/IOSCs for services requested on DSL Premise Services (DSLPS) for Line Sharing and Loop Sharing.

     UNE-Loop Re-grades (Analog to Digital or Digital to Analog)

  • Applicable to CLECs requesting re-grade of existing UNE-Loops without change of service provider.

  • The service address provided on the LSR should match the service address on the customer service record. See Order Activities and Pre-Order Transactions for Loop Service table above for Pre-Order information.

  • A Desired Frame Due Time (DFDT) must be specified on the LSR and will be honored within normal business hours if dispatch is not required. When dispatch is required, an all day appointment will be given. (East only)

  • Interactive eWPTS users can determine if dispatch is required via eWPTS. (East only)

  • Non-interactive eWPTS users will be contacted by the RCCC. (East only)

  • If dispatch is required, Verizon requests CLECs to notify RCCC of "Go / No-Go" decision no later than start of business on the due date in order to allow Verizon to prevent dispatch on possible "No-Go" orders. (East only)

  • If CLEC meetpoint remains the same and outside facilities change (e.g. UDLC to copper), Verizon frame and installation technicians will coordinate a cutover time to minimize an out-of-service condition. (East only)

  • The RCCC will turn up the re-graded loop to the CLEC upon provisioning completion. (East only)

  • Requests to "throw back" to previous service condition will not be honored. A separate LSR will be required to reverse re-grades after provisioning is complete.

  • Network Loop Modifications are not currently supported on analog to digital (or digital to analog) UNE-Loop re-grades. (East only) DSL conditioning, however, as it currently exists today, can be done on a re-grade from an analog to digital loop.

  • The following chart is a brief guide to identify which UNE Loops are eligible for re-grade. More detailed information can be found in the Business Rules.

Type of Re-grade



REQTYP = "AB", ACT = "C", LNA = "C", CI. = "E"

REQTYP = "AB", ACT = "C", LNA = "C"

Existing Analog to Digital (TXNU to ARDU)

TOS 2nd and 3rd character = "22" or "23"

TOS 2nd and 3rd character = "2F"

Existing Digital to Analog (ARDU to TXNU)

TOS 2nd and 3rd character = "1-"

TOS 2nd and 3rd character = "1F"

     Line Partitioning (Verizon East) allows a DLEC to add their DSL to an existing resold line. There is no business relationship between the DLEC and Reseller. The Reseller can migrate the voice if the data exists. Line Partitioning is only available with a signed commercial agreement between the DLEC and Verizon. Please contact your account manager to obtain this agreement.
