Product Description
The CentreCOM Micro Hubs are twisted pair hubs intended to connect eight IEEE 802.3 10Base-T network segments through one unit. Each hub has one twisted pair port specifically designed with an uplink (cascading) capability supporting a Media Dependent Interface (MDI/MDI-X) crossover switch. Four hubs can be cascaded together to form an independent workgroup containing as many as 26 nodes. To form an independent workgroup, the micro hubs are equipped with a Backbone Enable/Disable Switch to separate (or reconnect) all connected or cascaded nodes from the backbone ports.These micro hubs utilize the latest IC and Surface Mount Technology (SMT), which increases functionality and reliability. Additionally, these hubs are small in size, yet they provide the complete functionality of large hubs including packet regeneration and network partitioning. The packet regeneration results in a higher performance network by regenerating preamble, retiming the data packets and extending collision fragments to ensure collision enforcement by all nodes. Each segment automatically detects the polarity of the receive pair and reverses should the pair be incorrectly installed. The IEEE defined link integrity test function continually monitors the receive pair to ensure link continuity. It also includes a partitioning capability where each segment automatically disconnects itself after repeated collisions are detected. The hubs supports jabber lock-up protection on all interfaces, preventing transceiver lock-up resulting from packets that exceed the maximum packet length.Electronics:
