Tex. Utilities Code § 60.163: INFRASTRUCTURE SHARING.

(a) The commission shall adopt rules that require a local exchange company to share public switched network infrastructure and technology with a requesting local exchange company that lacks economies of scale or scope, to enable the requesting company to provide telecommunications services in each geographic area for which the requesting company is designated as the sole carrier of last resort.

(b) The rules governing the sharing:

(1) may not require a local exchange company to make a decision that is uneconomic or adverse to the public;

(2) shall permit, but may not require, joint ownership and operation of public switched network infrastructure and services by or among the local exchange companies that share infrastructure; and

(3) shall establish conditions that promote cooperation between local exchange companies.
