Abstract:
A system for generating a network analysis model is provided. The system comprises a text-based model definition file representing analysis flow and a hierarchical analysis tree; an analysis function block library comprising a plurality of analysis nodes in an analysis model definition, wherein each of the analysis nodes comprises at least one reusable analysis block; and a code generator that automatically generates code to implement the analysis model from the analysis function block library by parsing the model definition file.
Multijunction Unit Apparatus For Use In A Digital Network

Pacific Bell - San Francisco CA
International Classification:
H04L 900
US Classification:
380 50
Abstract:
Disclosed is an adaptive multijunction unit apparatus for multiplexing data streams between a master computer and a plurality of slave computers coupled through telephone system communication lines. The apparatus receives and processes both user data and network data which can include commands instructing the apparatus to change the operating modes of its various circuit components. For example, the adaptive multijunction unit apparatus can respond to commands to raise or lower its data transmission rate or to switch between dual channel and single channel data transmission. The apparatus includes a splitter/combiner function which copies data received from the master computer, onto output ports directed to multiple slave computers.

International Classification:
H04L 902 H04J 322 G06F 734
US Classification:
380 49
Abstract:
An apparatus for transferring digital data between time-domain multiplexed communication links of a telephone system which forms part of a computer network. A time-domain multiplexed communication link interface unit for transferring digital data between a first channel on a first time-domain multiplexed communication link and a second channel on a second time-domain multiplexed communication link of a multipoint communication network is disclosed. The multipoint communication network includes a plurality of network units with at least two of the network units comprising said time-domain multiplexed communication link interface units. The network units are coupled to telephone system communication links. The network units transmit and receive digital data in a frame mode in which the data is organized into frames on the communication links.

H04L 900 H04Q 1104
US Classification:
370 60
Abstract:
An apparatus for coupling data processing equipment to subscriber loops in a telephone system based computer network is disclosed. The multipoint communication network includes a plurality of network units with at least two of the network units comprising the apparatus in question. The network units are coupled to telephone system communication links. The network units transmit and receive digital data in a frame mode in which the data is organized into frames on the communication links. The network units also communicate with each other in a manner which allows the configuration and speed of the network to varied in response to the time of day and error rates observed on the telephone system communcation links.
A device includes a processor and a checksum module, wherein the checksum module calculates, for first data, an updated checksum that complies with Internet Engineering Task Force Request For Comments Number 1624 using twos-complement arithmetic. The processor replaces the original checksum with the updated checksum to update a data packet.
