摘要: A terminal for a telecommunications system provides access to one or two high-speed synchronous transmission lines by both low-speed transmission lines and subscriber lines. A core module includes interfaces to the high-speed lines, a time slot interchanger, an interface to the low-speed transmission lines, processors and overhead circuitry for supporting the terminal. An access module includes a plurality of line shelves connected to subscriber lines, each line shelf includes a pair of processors and for time slot assignors. A multi-link serial bus connects the time slot interchanger to the access module and to the low-speed interface and provides close coupling between the processors in the core module and the line shelves. The processors cooperate to groom subscriber information from said subscriber lines to and from time slots in said high-speed feeder line and said low-speed transmission line. Subscriber information may also be groomed between time slots of the high-speed feeder line and the low-speed transmission lines and between time slots within each subscriber line.

摘要: A control method and apparatus for an electronic system having a plurality of functional elements, both intelligent and non-intelligent, interconnected by a plurality of time-division multiplexed serial data links, wherein information is normally conveyed in time slots on the data links. Control information is exchanged between the elements by using one or more of said time slots as control channels for all control information. The format of the control information is compatible with both the intelligent elements and non-intelligent elements. The control information format includes a plurality of bits for providing command data, a plurality of address bits, a valid bit to indicate that the information being transmitted is a valid message, an interrupt bit to signal a microprocessor in an intelligent device to interrupt and service the message, and a parity bit for error checking.
