DataNET Hub Operation

DNH Links

Figure 1-4. DNH Links

Figure 1-4 shows the individual links that connect three DataNET hubs and several end devices.

The inter-hub links travel across twisted-pair copper or fiber-optic cables. The link data rate is 2.048Mbps for both cables. The DataNET hub soft- ware auto-detects the type of medium used on each DataNET port, and configures the hub accordingly.

Each connection between a DataNET Hub (DNH) and another device consists of two links. One link connects to the DNH ‘A’ Hub, and one link connects to DNH ‘B’ Hub. Both links can carry network traffic in normal operation. In the event that one link becomes unusable for any reason, the DNH will transparently and automatically re-route traffic on the re- maining redundant link.

DNH and Maxum Com Boards

An Advance Network Gateway or Maxum Analyzer that has an Advance Network Communication Board/DataNET (ANCB/DN) can connect to a DataNET hub via any of the eight down-stream ports. The ANCB/DN within these devices functions identically to a DNH.
