Common Language
Facility Detail -- Line Interface Equipment:  
CLFI Bank Codes

Common Language Facility Detail - Line Interface Equipment (Bank) Codes are the standard identification for identifying the termination of a facility. These codes are part of the Common Language Network Identification product line.


CLFI BANK CODE DESCRIPTION:  Common Language Facility Codes (CLFI Codes) provide definition and identification of a facility. When used with CLFI Bank Codes, they provide a complete end-to-end description of a facility.

CLFI Bank Codes can be found within the facility administration of the TIRKS® System and FEPS. In the F-1 module of the TIRKS System, CLFI Bank Codes provide a unique identification of the line-interfacing equipment. The interface equipment may consist of a plug-in circuit card, an equipment shelf/unit, or an entire frame of equipment, depending upon how a vendor implements interface functionality.

CLFI Bank Codes are assigned to plug-in circuit cards (e.g., DS1s, DS3s, T1, T3, OC-Ns), shelf(s)/unit(s) (e.g., add/drop multiplexers, Ethernet, optical network units, terminal shelves), and/or frames by being associated with a Common Language Equipment Code (CLEI™ Code) in the E-1 catalog.

By invoking a TIRKS System Function Code to assign a facility, the CLFI Bank Code provides the link between the F-1 and the E-1 inventory module. CLFI Bank Codes normally appear within a client's facility database (F-1 module) to supplement CLFI Code information.

Whenever an interface rate or signal type is part of the equipment name provided by the vendor, that rate/signal type will be included in the description of the CLFI Bank Code.

CLFI BANK CODE REQUESTS:  Requests can be submitted via the Bank Code Request Form. Product documentation is requested with each vendor submitted request.
