The TSX-1620 is a high-speed stand-alone Token Ring switch with the ability to
transparently switch packets among its various attached ring networks at full line
rate (4 or 16 Mbps) and with minimal latency. The TSX-1620 provides source
routing functions while using store and forward switching technology. The TSX-
1620 also provides virtual networking capability, allowing you to configure
logical rings that include multiple physical rings attached to the front panel ports
(e.g., physical rings inserted in ports 1, 2, 5, and 8 could all be assigned to a single
virtual ring network, and would communicate as if they actually were on the
same physical ring). Using this capability, 4 and 16 Mbps devices can be placed on
separate physical rings (each port automatically determines the speed of the ring
to which it is connected), allowing the 16 Mbps devices to operate at full speed,
and the switch can treat both rings as a single logical ring network. Broadcast
discovery packets can be confined to a virtual subset of the attached rings, thereby
reducing overall traffic on the switch.
The TSX-1620 is an 8 port switch which is expandable to 16 ports, with STP/UTP
and 4 or 16 Mbps on each port via front panel RJ-45 connectors. The device is
IEEE 802.5 compliant with support for IEEE 802.1d spanning tree, and supports
SNMP, including MIB II.
Using the TSX-1620 User’s Guide
Your SPECTRUM Portable Management Application (SPMA) for the TSX-1620
consists of a number of different applications, each of which provides a portion of
the overall management functionality. Each of these applications can be accessed
from the icon menu (if you are using a management platform) and from the
Stand-alone Launcher or the command line (if you are running in stand-alone
