Description Allied Telesyn's TurboStack Family provides a full-featured, managed stackable hub solution designed for both workgroup and department concentrator environments. The AT-TS12T hub comes with 12, the AT-TS24T with 24 10Base-T ports (Telco.) An additional modular port (pre-configured with AUI applique) provides seamless connectivity through a broad range of appliqus.The AT-TS12T and AT-TS24T hubs can function as standalone units, a stackable workgroup solution, or they can be configured as a departmental concentrator with up to eight units mounted into a chassis. The TurboStack utilizes integrated segment switching technology, providing full 10 Mbps dedicated bandwidth to each hub unit. In this configuration, 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) can eliminate network bottlenecks. Each hub unit is capable of storing up to 300 MAC addresses. They can be entered into the MAC address table in two different ways. First, the user can manually add or delete addresses. When a new piece of equipment is attached to the hub, its pre-defined MAC address will be recognized. In addition, the hubs can be configured to update their tables automatically through Learning Mode, as pieces of equipment are connected to it. If the hub is switched back to Static Mode, all addresses will be kept until the user either manually deletes them, or they are updated in Learning Mode again. 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. The AT-TS12T and AT-TS24T hubs support industry standard network management stations through their SNMP agent. Local management is provided through an ASYNC terminal/serial port (Omega Local), which also supports modem dial-up. In addition, the Omega Remote interface can be utilized in an in-band fashion through a Telnet session. Allied Telesyn's Simplified Icon Management (SIM) allows the stack to be represented as two icons: one for the stacked hubs, and one for the switch. Support for RMON minimizes repetitive tasks and console time by providing detailed network visibility.
