Rules & Regulations of the State of Tennessee
Title 1220 - Tennessee Public Utility Commission
Subtitle 1220-04 - Division of Public Utilities
Chapter 1220-04-06 - Ten Year Master Plan for Technology Deployment by Telephone Companies
Section 1220-04-06-.03 - FUNDAMENTAL SERVICE CAPABILITIES

(a) Intelligent Network Capability or Signaling System 7 (CCS #7) - This technology enables the telephone company to provide customer services such as caller ID, selective call forwarding, selective call blocking and data base access services as well as improved data transmission services for businesses. It will improve the network operations for local telephone companies which will result in greater cost savings and operating efficiencies in the future. Signaling System 7, which sets up a call faster and allows more customized services than its predecessor, is already in place in Tennessee's urban counties. The Plan accelerates deployment throughout the State.

(b) Integrated Service Digital Network (ISDN) - This will provide for simultaneous data, video and voice transmission over the same lines. This capability allows an order of magnitude increase in the digital transmission capacity compared to existing voice grade services and can support services such as high speed Fax, video and secure voice communication. Prior to adoption of the Master Plan, ISDN would have been implemented slowly beginning in 1992, with some areas of Tennessee not having ISDN capabilities within the next ten (10) years. The Plan accelerates deployment, making ISDN available statewide by 2000.

(c) Broadband - This encompasses high speed services requiring a fiber optic transmission system and broadband digital switches. This capacity includes transmission at forty-five (45) megabits per second and up, and supports such services as full motion interactive video, high definition television, and high speed data transmission. Broadband capacity is not currently available in some areas in Tennessee, but is expected to be available after 1995 under the Plan.
