Patent number: 5452297Abstract: Pulse Code Modulation (PCM) signal streams are converted into Asynchronous Transfer Mode (ATM) cells for switching and transmission across a telecommunications network. Each cell carries one PCM sample of up to 48 different voice connections, the voice connections being selected from the PCM data streams because they have a common destination. The cells are transmitted over ATM virtual paths, each path transmitting one cell every 125 .mu.s. The ATM signals are switched by units for switching cells (cell switching), while keeping their payload contents intact, and by units for switching the signals for individual voice connections between cells of an ATM signal (cell remapping). Advantageously, ATM transmission systems interface with PCM systems without adding appreciable delay and without requiring additional buffering. Advantageously, new voice paths can be established most of the time by using available slots in the cells of existing virtual paths.Type: GrantFiled: December 20, 1993Date of Patent: September 19, 1995Assignee: AT&T Corp.Inventors: Thomas L. Hiller, Ronald A. Spanke, John J. Stanaway, Jr., Alex L. Wierzbicki, Meyer J. Zola

Patent number: 4873717Abstract: A call coverage arrangement in which coverage personnel are informed of the switch-hook status of covered terminals by way of a single two-part indicator on the coverage terminal. The two-part indicator indicates switch-hook status for any one of a number of covered terminals. The first part of the indicator identifies the covered terminal and the second part defines the switch-hook status of the identified terminal. The arrangement is flexible in providing coverage for additional terminals and in providing coverage via forwarding from any termianl, since there is no need to assign and dedicate status indicators to particular terminals.Type: GrantFiled: June 14, 1988Date of Patent: October 10, 1989Assignee: American Telephone and Telegraph Company, AT&T Bell LaboratoriesInventors: Wayne A. Davidson, John P. Ernst, Marybeth Herkes, Ram Kuppuswami, Timothy A. Satalich, John J. Stanaway, Jr.
