TruOps Common Language Equipment Identification:
CLEI™ Assignment Codes and CLFI™ Bank Codes

Common Language CLEI codes are developed for the assignable hardwired equipment provisioning process. There are two types of CLEI codes provided for assignable hardwired equipment: CLEI equipment codes and CLEI assignment codes (also known as logical codes, HECI or HECIG).

CLEI ASSIGNMENT CODES:  CLEI assignment codes identify assignable equipment entities such as mountings, slots and ports. Service providers rely on CLEI assignment codes for circuit design, circuit layout, assignment, and network inventory processes. Each CLEI assignment code and associated record provides configuration and wiring information for a targeted assignable equipment entity.

The TIRKS System requires CLEI assignment codes and records in order to create Function codes. Function codes are then used to satisfy a specific set of circuit-design requirements.

Example:  An OC-3, ATM-based, single-mode fiber interconnection cannot be provisioned to a customer unless TIRKS System Function codes have specified which manufacturers' equipment can provide this function, and CLEI assignment codes have identified the OC-3, ATM port and the slot by single-mode wiring.

Each CLEI assignment code uniquely represents an equipment item's critical capability. Improper representations of equipment configuration can occur when certain CLEI assignment codes are not developed. This coding analysis and code development must be performed before TIRKS System Function code work can be completed.

For OSMINE Services contracted work, both CLEI code and Function code teams work together closely to ensure that enough CLEI assignment codes can be created to meet the provisioning as well as network services, monitoring, and remote programming needs from downstream operations systems such as NSDB, NMA and TEMS.



CLFI BANK CODES:  In order to complete the OSMINE Services process, equipment vendors may need to request Common Language Facility Detail -- Line Interface Equipment (Bank) Codes, the standard identification for identifying facility terminating equipment within administration and planning systems.

The CLFI bank code provides a unique identification of equipment at a line interface. The interface equipment may consist of a plug-in circuit card, an equipment shelf/unit, or entire frame equipment, depending upon how a vendor packages the equipment.

CLFI bank codes are alpha or alphanumeric and are one to six characters in length. They normally appear within a client's facility database to supplement Common Language CLFI™ codes.

CLFI BANK CODE REQUESTS:  All vendor CLFI bank code requests must include product documentation. The customer must submit this documentation with a completed Common Language Products LS2 form.

Request Types:
  1. Request From TIRKS System to Match With Function Codes (Non-OSMINE Services)
    • New product/product version that is not currently CLFI bank coded
    • Secondary request for new interface on an existing CLFI bank-coded product. (No new product functions. Only used to add new facility interface.)

  2. Scheduled Request From TIRKS System to Match With OSMINE Services Work
    • A new product/product version that is not currently CLFI bank coded
    • Secondary request for new interface on an existing CLFI bank-coded product. (No new product functions. Only used to add new facility interface.)

All OSMINE Services-related Common Language Products would do CLFI bank coding on a scheduled basis. Scheduling between Common Language Products and OSMINE Services project managers must occur at least two weeks prior to request submission.

All CLFI bank code requests received from contracts signed after March 1, 2003 will follow the new "Charge Per Bank Code" model.

Unscheduled requests and requests to match up with Function codes will be worked only as time permits. Requests without vendor documentation are improper and will not be worked.
