Abstract: Techniques for dynamically managing capabilities on network monitoring devices are provided. A client application interface associated with a client device for a user to manage network capabilities on network monitoring devices may be provided. An indication of the user renting a first network capability from the client device may be received. The first network capability may be enabled on a first network monitoring device associated with the user.

Abstract: A testing apparatus and method of extending the life of a testing apparatus may comprise a chassis including a case having a testing module receptacle receiving a plurality of testing modules comprising at least one processor module and a plurality of test modules, each having the same physical footprint, including respective racking mechanisms and inter-module interface connectors; and a backplane with connectors connecting with a respective inter-module connector, and bus-work interconnecting the respective modules through the inter-module interface connectors and the backplane connectors. The backplane may comprise a battery and display connector. The chassis may comprise a display mounting receptacle configured to receive a display unit having a display connector configured to interface with the backplane display connector. A battery receptacle may receive a battery unit, such as a rechargeable battery.

Abstract: A fault-location operating system for use with transmission networks using repeaters with loopback capabilities. A plurality of bidirectional transmission links L.sub.i, for i=1 through N, are used for transmission of data between the terminals. A test control unit is connected at the first terminal to the first end of the first transmission link L.sub.1, and controls transmission of control signals across the first transmission link L.sub.1. A plurality of repeaters R.sub.i, for i=1 through N-1, are used for interconnecting the plurality of bidirectional links. Each repeater R.sub.i is connected to the first end of one transmission link L.sub.i and to the second end of another transmission link L.sub.i+1. Each repeater includes a first circuit for repeating data transmitted from the one transmission link L.sub.i for transmission on the other transmission link L.sub.i+1, and a second circuit for repeating data transmitted from the other transmission link L.sub.
