1.2 STHI Overview
The STHI is an SNMP compliant intelligent hub that provides basic
management functionality including port and station control, statistical
error and trap tracking, and enhanced beacon recovery for a Token Ring
LAN. Its front panel TCU (Trunk Connector Unit) ports allow for network
connections to either active stations or passive Multi-Station Access Units
(MAUs) while its TPIM (Token Ring Port Interface Module) ports allow
for ring expansions across a variety of media. Its rear panel HubSTACK
ports provide for ring expansion through connections to multiple STH
non-intelligent hubs. See Figure 1-1.
