    摘要: A system and method for accessing a number of communication lines by one or more testing devices are disclosed. Each of the communications lines is coupled through the system and includes a first termination at a first telecommunications termination site and a second termination at a second telecommunications termination site. The system includes a number of line access devices, each of which is coupled to at least one of the communication lines terminating at the first telecommunications termination site and at least one of the communication lines terminating at the second telecommunications termination site. One or more monitoring busses are defined by a number of relays, one or more of which is coupled to one of the line access devices. A test device interface, which is selectively coupled to the bus, provides bi-directional connectivity between the selected communication line and a selected testing device coupled thereto. An activated one or more of the relays couples a selected one of the communication lines to a selected one of the testing devices via the test device interface. A single or multiple patch capability provides for manually establishing cross-connections between selected communication lines and for redirecting communication line connections to selected testing devices. The test access system and method accommodates various high speed digital transmission line protocols. The transmission lines coupled through the system may comprise high speed digital transmission lines characterized by transmission rates on the order of tens, hundreds or thousands of megabits per second (Mbps).

    摘要: A system and method for accessing a number of communication lines by one or more testing devices is disclosed. Each of the communications lines is coupled through the system and includes a first termination at a first telecommunications termination site and a second termination at a second telecommunications termination site. The system includes a number of line access devices, each of which is coupled to at least one of the communication lines terminating at the first telecommunications termination site and at least one of the communication lines terminating at the second telecommunications termination site. The system further includes a test device interface, signal direction circuitry, a communications device that facilitates remote access to the test access system by a remote processing unit, and a control device. The control device controls the signal direction circuitry to couple a selected communication line to a selected testing device coupled to the test device interface in response to a control signal received from the remote processing unit. The control device may also control the signal direction circuitry to couple a first selected line access device with a second selected line access device so as to establish a cross connection between the first and second selected line access devices. The test access system provides testing, monitoring, and cross connecting of high speed digital transmission lines, such as digital transmission lines characterized by transmission rates on the order of tens or hundreds of megabytes per second

The system includes a number of line access devices, each of which is coupled to at least one of the communication lines terminating at the first telecommunications termination site and at least one of the communication lines terminating at the second telecommunications termination site.

An activated one or more of the relays couples a selected one of the communication lines to a selected one of the testing devices via the test device interface. One or more signal paths defined as passing through the relays, test device interface, and a portion of the line access devices define untapped point-to-point connections. The testing access system and method of the present invention accommodates various high speed digital transmission line protocols. The transmission lines coupled through the system may comprise high speed digital transmission lines characterized by transmission rates on the order of tens or hundreds of megabits per second (Mbps).

    摘要: An enhanced MAU (EMAU) is provided which can be used in token ring networks in place of existing MAUs, yet permits each station on the network to be selectively connected to any one of a plurality of different token ring trunk cables. Each EMAU also includes an internal processor and internal coupling units (ICUs) which connect the processor to each of the trunk cables. Each ICU provides the processor a dedicated presence on each of the trunk cables in the same manner as a conventional station. In addition, the processor includes all of the hardware and software necessary to control the ICUs and to communicate over each cable in the same manner as a station. Accordingly, the processor may take full advantage of all fault protection, control and management procedures built into the token ring operating protocol.

    摘要: An enhanced MAU (EMAU) is provided which can be used in token ring networks in place of existing MAUs, yet permits each station on the network to be selectively connected to any one of a plurality of different token ring trunk cables. The EMAU uses the conventional trunk coupling units (TCU) of an MAU, which permit a station to be connected in the ring or to be bypassed, but adds to each TCU a multi-switch device which permits the TCU to be connected to one of a plurality of ring trunk cables while providing a bypass across the station in the remaining ring trunk cables. In addition, the EMAU provides sensing of the input and output signal for each station, which permits the EMAU to monitor the address produced by each station during the normal ring polling process which occurs during neighbor notification operation of the token ring network. Each address is then stored in a location associated with the physical location of a station. Sensing of the input and output signal is also utilized to perform a peak amplitude comparison between the two, to derive signals indicative of the input-output operability of each station.
