Allied Telesyn AT TS12TR

Allied Telesyn AT TS12TR ... contains 12 10Base-T ports. An additional modular port (pre-configured with AUI appliqué) provides seamless connectivity through a broad range of appliqués.

The AT-TS12TR can function as standalone units, as a stackable workgroup solution, or as a departmental concentrator with up to eight hubs mounted into a chassis. The TurboStack can also utilize integrated segment switching technology, providing a full 10 Mbps dedicated bandwidth to each hub. Up to six hubs can be connected to a switch via a segmented backplane chassis. High-speed uplink ports for 100Base-TX (AT-TS90TR) and ATM (AT-TS95TR) eliminate network bottlenecks. Each hub has the capacity to store up to 300 MAC addresses. If entered into the MAC address table as follows: First, the user can manually add or delete addresses. When a piece of equipment is attached to the hub, its pre-defined MAC address is recognized. In addition, the hubs can be can automatically update the MAC table through Learning Mode, as equipment is connected to the hub. If the hub is switched back to Static Mode, all addresses are kept either until the user manually deletes them, or until the addresses are updated in Learning Mode. Secure and reliable data transactions are provided through Intrusion Prevention. In Static Mode, the MAC addresses of equipment that try to access the network are identified: unapproved addresses are blocked. If an intrusion is recognized, the port can be auto-partitioned, with an SNMP trap sent to the network manager. Redundant Links, Redundant SNMP management and hot-swap capabilities of the hubs increases network uptime and yield cost savings.
