    摘要: A mechanized system distributing the access, test and communication functions to the point of testing, typically the centralized switching facility serving the telephone loops and equipment to be tested. Computer (200) stores information about each subscriber loop in the geographical area served by a system. Front-end computers (220,221) interact with computer (200) to retrieve pertinent data regarding loops to be tested. Each switching facility in an area includes a loop testing system (e.g., 160) that implements the required functions. The communication functions residing in front-end computers (220,221) and loop testing systems (160,161) are coupled via a data communication network (140) in a manner that allows any front-end computer to communicate with any loop testing system. Users of the system control access and test from consoles having the capability of establishing independent communication paths over the national dial network for interactive tests on loops accessed through standard test trunks. Microprocessor-based circuitry is utilized for numerous system tasks such as signal generation, digital signal processing and controlling sensitive analog measurements. Signal generation includes digital generation of analog waveforms. Signal processing techniques incorporate various digital filters to analyze sample sequences derived from, for example, dial pulses and coin telephone signals. Sensitive analog measurements of loop characteristics are effected with a magnetic current detector that operates over broad current and frequency ranges. Frequency dependent measurements are converted to DC using synchronous demodulation techniques to enhance resolution.

    摘要: The system and method of the invention enable any channel of a multi-channel communication link to be used for transmission of a control signal to a system component by a system controller. The system component, connected to the system controller by the multi-channel communication link, automatically locates the one or more signaling channels carrying the control signal(s) and then establishes communication with the system controller in accordance with the control signal(s). If no signaling channels are located after a predetermined number of attempts or after a predetermined period of time, the system component may, if particular conditions are met, reset itself before continuing to search for the signaling channel(s).

    摘要: A communications system that is arranged to transport so-called connection oriented messages via respective virtual circuit connections is enhanced so that it also transports so-called connectionless messages via a predefined virtual circuit connection that is common among those data modules which participate in the connectionless message service. In particular, each module which participates in the connectionless message service is assigned, in addition to a primary address that is used in conjunction with associated channels numbers to transport respective connection oriented messages, a common address and a channel number that is used solely for transporting connectionless messages. In this way, the communications system processes connectionless messages as though they were connection oriented messages.

    摘要: Multi cast techniques are employed to provide host computer elements access to multiple redundant servers of a communication network in such a way that the hosts need not know which of the servers is active. In one embodiment, the servers provide a gateway function between an Ethernet LAN and an external network. The Ethernet LAN comprises one or more hosts connected to one or more switches, the switches connected to corresponding servers defining an active/standby pair. The servers are connected to an external network by corresponding active/standby links. The hosts send messages directed to a multicast address to at least one of the switches. The switches forward the messages on ports according to a multicast routing topology having been determined by performing IGMP “snooping” of messages issued from the servers. Both the active and standby servers receive the messages; and the active server sends the messages to the external network. In case the active server fails or is removed from service, the standby server is promoted to active server and assumes the role of the formerly active server without necessitating any communication to the hosts to inform them of the change in status of the active server.
