Configuration Status Display

This article describes a technique for representing the configuration status of a wiring concentrator of the sort used for in-plant ring networks.

The wiring concentrator can be thought of as a junction box, or distribution panel, through which a main trunk is wired. For this application, the concentrator is more than a passive patch panel; active elements and control logic are assumed. Individual branch circuits called lobes are provided off the main trunk. Each lobe is in series with the main trunk and is provided with shunt (bypass) circuitry to permit its logical insertion into, or removal from, the trunk.

In addition, the trunk itself is provided with reconfiguration capability, either automatic or manual, through the use of an alternate trunk wired through the wiring concentrator. Appropriate wrap or bypass controls in the concentrator permit trunk reconfiguration.

This type of wiring concentrator can exist in one of several states, depending on the status of its lobe bypass and trunk wrap control circuits. These states are as follows (Fig. 1): a) Normal

b) Lobe Bypassed

c) Front-End Wrapped

d) Front-End Wrapped with Lobe Bypassed

e) Back-End Wrapped

f) Back-End Wrapped with Lobe Bypassed

g) Shunted

h) Isolated

i) Isolated with Lobe Bypassed.

Given the existence of an in-plant ring network and the presence of one or more wiring concentrators of the type described above, how can the status of a concentrator be displayed, simply and unambiguously, for the benefit of network operation and maintenance personnel?

The representation format proposed here is based on a segment oriented liquid crystal display (LCD) or light-emitting diode (LED) device. Assume, for purposes of discussion, that the wiring concentrator supports four lobes. Then the readout proposed would consist of the overlay and segmented display shown in Fig. 2. The overlay is glass, and the a...
