Tenneco Gas and Tenneco Inc. have discrete Information Services departments with separate computer services organizations; however, Tenneco Gas supports all telecommunication functions. Tenneco Gas has standardized intelligent desk-top terminals for a major portion of its business information strategy. The data communication application requirements have spawned a variety of networks that range from departmental high-speed bus architecture networks to star networks providing Personal Computer (PC) connectivity for host processing systems and, finally, to switched networks interfacing external databases. The evolution from analog to Integrated Services Digital Network (ISDN) telecommunication services became a reality for Tenneco during the summer of 1988. Early in May 1988, the local exchange carrier, Southwestern Bell Telephone Company, migrated Tenneco, as well as other customers, from a No. 1AESS analog switching system to a No. 5ESS digital switching system. Through the course of the summer, Tenneco completed the conversion of approximately 2,200 multi-button analog telephone sets and associated lines to ISDN sets with full-featured basic rate interfaces.
