Sec. 51.309  Use of unbundled network elements.

    (a) Except as provided in Sec. 51.318, an incumbent LEC shall not 
impose limitations, restrictions, or requirements on requests for, or 
the use of, unbundled network elements for the service a requesting 
telecommunications carrier seeks to offer.
    (b) A requesting telecommunications carrier may not access an 
unbundled network element for the exclusive provision of mobile wireless 
services or interexchange services.
    (c) A telecommunications carrier purchasing access to an unbundled 
network facility is entitled to exclusive use of that facility for a 
period of time, or when purchasing access to a feature, function, or 
capability of a facility, a telecommunications carrier is entitled to 
use of that feature, function, or capability for a period of time. A 
telecommunications carrier's purchase of access to an unbundled network 
element does not relieve the incumbent LEC of the duty to maintain, 
repair, or replace the unbundled network element.
    (d) A requesting telecommunications carrier that accesses and uses 
an unbundled network element consistent

with paragraph (b) of this section may provide any telecommunications

network element or a combination of unbundled network elements with 
wholesale services obtained from an incumbent LEC.
    (f) Upon request, an incumbent LEC shall perform the functions 
necessary to commingle an unbundled network element or a combination of 
unbundled network elements with one or more facilities or services that 
a requesting telecommunications carrier has obtained at wholesale from 
an incumbent LEC.
    (g) An incumbent LEC shall not deny access to an unbundled network 
element or a combination of unbundled network elements on the grounds 
that one or more of the elements:
    (1) Is connected to, attached to, linked to, or combined with, a 
facility or service obtained from an incumbent LEC; or
    (2) Shares part of the incumbent LEC's network with access services 
or inputs for mobile wireless services and/or interexchange services.
