摘要： A data communication method and circuitry which uses a compatible subset of a standard high level data link control (HDLC) protocol to control link level communication between a digital terminal and a switch. The use of the subset of HDLC protocol reduces the complexity of the digital terminal design while maintaining communication compatibility with a switch which uses either the standard HDLC protocol or the subset of HDLC protocol.

摘要： A communication method and digital multi-customer data interface for interconnecting a number of customer terminals to a main packet switching network of a local area data transport system that provides data communication services such as interactive video text service between data service vendors and customers. The digital multi-customer interface utilizes a main processor, control circuit, and multi-customer protocol controller to implement the protocol functions for the communication of packets and control information over individual serial transmission paths. The multi-customer protocol controller comprises a control processor and a formatter circuit for synchronously communicating packets for a plurality of customer terminals via customer line units and customer lines. The control processor performs byte-to-packet and packet-to-byte functions between the main processor and the formatter circuit. The formatter circuit is shared in common by all of the customer lines and performs the functions of assembling and disassembling data bytes from and to individual data bit signals, performing error cyclic redundancy checks and generations, performing flag recognition and generations, and performing bit stuffing and unstuffing. The control circuit handles communication of all control and status information between the main processor and the customer line units. The control buffer periodically transmits the control information received from the main processor to all of the customer units and receives back from them status information which is stored for later use by the main processor.

摘要： A duplex time-space-time switching network is shown in which there is a multiple crossover of voice information from one rail to another rail in a large digital switching system. The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in the originating and terminating time switching stages but remain segregated throughout the space switching stage.

摘要： Signals from line circuits requesting service are transferred to a T1 channel via a Pulse Amplitude Modulated (PAM) bus. The number of line circuits which can be served by a T1 line is not limited by the capacity of the T1 line since the probability of all line circuits requesting service at the same time is extremely low. A processing unit detects requests for service and assigns them a slot in a memory which defines the scanning sequence for insertion of line circuit signals in the T1 channel.
