TLDR
The Asynchronous Packet Manager (APM) as mentioned in this paper is an interface for transferring data in a first format between a data terminal equipment and a combination data and telephone switching system in a properietary packet format.Abstract:
The Asynchronous Packet Manager is the interface for transferring data in a first format between a data terminal equipment and a combination data and telephone switching system in a properietary packet format. A microprocessor accepts data from a universal asynchronous receiver transmitter and forwards the data to a mini packet receiver transmitter, when it is formatted into mini packets and converted to an alternate mark inversion signal and sent to the switching network.read more

Method and apparatus for reordering frames
Brian Gallagher,Miklos Sandorfi +1 more
TL;DR: In this paper, a frame prioritization circuit forwards frames received by a selected port to a frame handler for processing and a frame routing circuit routes frames processed by the frame handler to at least one of the ports associated with at least a destination node.
Patent
Hardware interface to a high-speed multiplexed link
TL;DR: In this paper, a link interface to a high-speed asynchronous multiple-xed ATM telecommunication link includes a data segmenter for forming ATM cells out of data frames, and a data assembler and state memory for assembling data frames out of received multiplexed (interleaved) ATM cells.
Patent
Protocol-to-protocol translator for interfacing disparate serial network nodes to a common parallel switching network
TL;DR: In this paper, the authors propose a combination of a serial line switching apparatus and an ALLNODE parallel switching network to enable serial message data to be switched and routed to various destinations.
Patent
Multi-media serial line switching adapter for parallel networks and heterogeneous and homologous computer system
TL;DR: In this paper, the authors propose a serial line switching apparatus for performing either parallel or serial communications among multiple nodes over switching networks, which can adapt standard and proprietary serial interfaces using either optical or electrical transmission media to interface to the parallel switch.
Patent
Reliable message transmission with packet-level resend
TL;DR: In this paper, a method for communication over a network includes receiving from a host processor a descriptor defining a message including message data to be sent over the network, and responsive to the descriptor, generating a sequence of packets each containing a respective portion of the message data.

Data switching system and method
TL;DR: In this paper, a high speed data bus is time division multiplexed into multiple logical timeslot channels and each of these channels is dynamically allocated to multiple endpoints within the data communication system.
Patent
Alternate Mark Invert (AMI) transceiver with switchable detection and digital precompensation
TL;DR: In this paper, a high-speed digital transceiver is provided for use in a PBX environment comprising twisted-pair wire cables interconnecting like transceivers, each transceiver being operative to exchange voice, data and control information in a packetized format over a common twistedpair cable.
Patent
Programmable feature card
TL;DR: In this paper, a signal processor with parallel input/output (I/O) data ports and a signal interface for converting the PBX signal format to a processor compatible format is presented.
Patent
Digital modem for multiple telephone circuits
TL;DR: In this article, a modem for exchanging information between a plurality of remote DTE's and a majority of local master DTEs is disclosed having multiple line interface and DTE interface circuits.
Patent
Simultaneous voice and data communication and data base access in a switching system using a tone bus or broadcast mode
TL;DR: In this paper, a combined telecommunications and data communications system operates by partitioning data wherein the PCM speech transmission data field is used to contain both digitized speech and other data in the same channel within a frame.
