Telecommunications Equipment Research and Manufacturing Competition Act of 1991

Telecommunications Equipment Research and Manufacturing Competition Act of 1991 - Amends the Communications Act of 1934 to authorize any Bell Telephone Company (BTC), through an affiliate of such company, to manufacture and provide telecommunications equipment, except that no BTC may engage in such manufacturing with an unaffiliated BTC or affiliates thereof.

Allows such manufacturing or provision to be conducted only through an affiliate that is separate from any BTC. Requires the Federal Communications Commission (FCC) to prescribe regulations to ensure that: (1) such manufacturing affiliate maintains separate accounts and records from its affiliated BTC which identify all financial transactions with the BTC; (2) neither a BTC nor any of its non-manufacturing affiliates carry out sales, advertising, installation, production, or maintenance operations for a manufacturing affiliate, except under specified conditions, such affiliate incurs debt entirely separate from and without recourse against the affiliated BTC; (4) such affiliate shall not be required to operate separately from any other affiliates of its BTC; (5) if an affiliate of a BTC becomes affiliated with a manufacturing entity, it shall be treated as a manufacturing affiliate of the BTC; (6) such affiliate shall make available any telecommunications equipment manufactured by such affiliate to any purchasing carrier, so long as each such purchaser does not manufacture such equipment or agrees to make available to the BTC or any of its affiliates any telecommunications equipment manufactured by such purchasing carrier or any of its affiliates for use with the public telecommunications network by such carrier or any of its affiliates; and (7) such affiliate shall not discontinue or restrict sales to other local exchange telephone companies of any telecommunications equipment until arrangements are made to provide to them the specifications, plans, and tools to allow them to arrange for the manufacture of such equipment by another entity.

Directs the FCC to require that each BTC maintain and file with the FCC complete information with respect to the protocols and technical requirements for connections with and use of its telephone exchange service facilities. Prohibits a BTC from disclosing any such information to its affiliates unless such information is immediately so filed. Requires any two or more carriers providing regulated telephone exchange service in the same area to notify each other of the deployment of telecommunications equipment.

Requires the FCC to ensure that manufacturers in competition with a BTC's manufacturing affiliate have access to information with respect to the protocols and technical requirements for connection with and use of its telephone exchange service facilities required for such competition that such BTC makes available to its affiliate.

Requires the FCC to prescribe regulations to require any BTC which has a manufacturing affiliate to: (1) provide to other manufacturers of telecommunications equipment and customer premises equipment that is functionally equivalent to equipment manufactured by BTC affiliates opportunities to sell such equipment to such BTC which are comparable to opportunities the BTC provides to its affiliates; (2) not subsidize its manufacturing affiliate with revenues from its regulated telecommunications service; and (3) only acquire equipment from its manufacturing affiliate at the open market price.

Allows a BTC and its affiliates to engage in close collaboration with any manufacturer of customer premises or telecommunications equipment during the design and development of hardware and software relating to such equipment.
