1.4 GENERAL DESCRIPTION

Cabletron Systems 3T01-04 and 3T01-02 modules connect the ATX to a 4 or 16 Mbps Token Ring network. The modules enable connectivity to FDDI, Ethernet, and Token Ring Networks, and can be conﬁgured to support Transparent Spanning Tree, Source Route, or Source Routing Transparent Bridging. The ATX is also able to translate higher level protocols to allow communication between end-user devices on Token Ring and end-user devices on FDDI or Ethernet. Protocols translated include: TCP/IP, Novell NetWare, and AppleTalk Phase II.

The Token Ring module ports can be connected to one Token Ring network. The module contains connectors for shielded twisted pair (STP) and unshielded twisted pair (UTP) cabling. Each module has eighteen LEDs which indicate the current status of the module and the Token Ring networks. The ofﬂine button allows you to remove the module for swapping.

Up to four Token Ring networks can be attached to either module. The module is available in two models: STP (3T01-04) and UTP (3T01-02). Each module contains four connectors (STP or UTP), 18 status LEDs, and an ofﬂine button.

The Token Ring module may be installed in any of the ﬁve interface slots and the ATX can simultaneously support up to ﬁve Token Ring modules. If ﬁve of either the 3T01-04 or 3T02-04 modules are installed, up to 20 networks can be connected.
