Network Management Control Bus

The H4TU-C provides a Network Management Control Bus on pin 7 of the card-edge connector. This allows the various Management System protocols to manage the H4TU-C through the HMU-319. Whenever the H4TU-C is under management, the MNGD message displays periodically on the front-panel display.

Some H4TU-C-319 features are affected when it is under management. Consult the management unit practice for further information (see “Appendix D - Product Support” on page 66).

Fuse Alarm

Pin 10 on the card-edge connector is a Fuse Alarm that is driven to -48 Vdc whenever its onboard fuse opens. It emulates the function of the Fuse Alarm output from pin 10 on normal, high-density (HD) repeaters. Pin 10 is connected to pin 5 of the 1184 Alarm Card (slot 1 in the HD shelf) and causes the 1184 Fuse ALM LED to light when the pin 10 signal is activated. Its normally floating output must never be driven above ground or below -80 V. It can sink a current of 10 mA. The H4TU-C does not support the BPV function (Pin E) of normal HD repeaters.
