TRS - Telecommunications Relay Service: A national and international program that provides functional equivalency of access to public switched telecommunications network services by persons who are deaf, hard of hearing, or speech disabled. In the U.S., the Federal Communications Commission (FCC) sets minimum required standards for TRS operations, and requires and certifies that each state meet these legal standards. The FCC mandated rules for TRS in response to Title IV of the Americans with Disabilities Act of 1990 ( ADA ) and its impact on Title 47, Code of Federal Regulations, Part 64. Each state is independently responsible for acquiring and administering its own TRS.

ULTS – Universal Lifeline Telephone Service: This PUC program advances the PUC policy of assuring access to telephone service to every California residents by allowing a discount on monthly bills to eligible low-income subscribers.
Unbundled: The separation of a service into its distinct elements, e.g., the provisions of natural gas to residential or industrial customers is now split into the transportation of natural gas via pipeline to the utility and the delivery of the gas from the utility to the user.
Uncollectibles: An amount of money that the utility cannot collect from the customer due to nonpayment of bills; estimated as a percentage of total revenue and treated as an expense item.
Undercharge: Any transportation charge below the filed tariff rate, the accepted reduced rate, or that is prescribed by the Commission in one of its MRTs. The PUC may impose and collect form the carrier a fine that equals the amount of the undercharge.
UNE-P - Unbundled Network Element Platform: Refers to the combination of infrastructure elements - including unbundled loops, switches, and transport elements - that CLECs must acquire to provide local telephone service to customers. By reducing the cost and time of provisioning service, UNE-P enables CLECs to provide local service in regions normally serviced by ILECs. A CLEC utilizing a UNE-P does not have to lease space in the ILEC central office but instead leases the network elements necessary to provide service from the ILEC. The UNE-P CLEC usually leases a copper loop, a port on the ILEC switch, and a connection to the CLEC's point-of-presence.
UNE Revenues: Revenues received from telecommunications carriers for Unbundled Network Elements.
UNEs – Unbundled Network Elements: Equipment of an incumbent telecommunications carrier that a competitor leases in order to provide service in the incumbent's service territory.
