Repeaters

There are desktop and rackmount department concentrator chassis
available to hold from two to eight AT-3600 series hubs. Since the
department concentrator chassis connects hub modules across a
backplane, a fully populated department concentrator behaves as a single
hub in the network topology.
The AT-3624TRS repeats 10BASE-T signals according to IEEE 802.3 hub
specifications. In an eight-slot department concentrator, up to 181 ports
may be monitored (seven Slaves containing 24 10BASE-T station ports
each and one Master containing 12 10BASE-T station ports and one AUI
network port).
Attention
The AUI network ports on the seven Slaves in an eight-slot department
concentrator cannot be used because they reside on the back panel of the
hub and are blocked by the backplane.
You can expand the number of ports by stacking multiple AT-3624TRS
hubs through the backplane connector, making a single logical hub.
Controllers
The AT-3624TRS repeater uses an ATI proprietary multiple port repeater
controller to retime and regenerate signals and communicate with the
network management software. The port status for each of the ports is
indicated by an LED display.
AT-3624TRS Port Configurations
Network Port
The AT-3624TRS repeater has an AUI port, as shown in Figure 16, located
on the back panel. This port may be used to connect the hub to the
network in the standalone configuration. In a managed hub, the Master’s
AUI port may be used for the network connection. In a non-managed hub
configuration, if you are using a two- or three-slot chassis, one AUI port is
used for the network connection and the remaining AUI port(s) may be
used for station connections.
