Sec. 51.335  Notice of network changes: Confidential or proprietary 
          information.

    (a) If an incumbent LEC claims that information otherwise required 
to be disclosed is confidential or proprietary, the incumbent LEC's 
public notice must include, in addition to the information identified in 
Sec. 51.327(a), a statement that the incumbent LEC will make further 
information available to those signing a nondisclosure agreement.
    (b) Tolling the public notice period. Upon receipt by an incumbent 
LEC of a competing service provider's request for disclosure of 
confidential or proprietary information, the applicable public notice 
period will be tolled until the parties agree on the terms of a 
nondisclosure agreement. An incumbent LEC receiving such a request must 
amend its public notice as follows:
    (1) On the date it receives a request from a competing service 
provider for disclosure of confidential or proprietary information, to 
state that the notice period is tolled; and
    (2) On the date the nondisclosure agreement is finalized, to specify 
a new implementation date.
