OVERVIEW
The HSIM-F6 extends the functionality of certain Cabletron Systems
interface modules or standalone hubs to include high-speed uplink
capability. The HSIM-F6 allows remote connectivity using FDDI
technology.

Features
Connectivity
The HSIM-F6 is equipped with slots for FDDI A and B ports. These two
ports allow connection to the ring as a Dual Attached Station (DAS) using
two FPIMs or as a Single Attached Station (SAS) using one FPIM.
ports allow connection to the ring as a Dual Attached Station (DAS) using
two FPIMs or as a Single Attached Station (SAS) using one FPIM.
As a DAS, the module or standalone hub that houses the HSIM-F6
connects directly to the FDDI primary ring. This provides the reliability
of an FDDI dual, counter-rotating ring topology. If one segment of the
FDDI ring becomes disabled, this dual ring configuration provides
redundancy and restores ring continuity.

As a SAS, the HSIM-F6 connects to the primary ring only by using a
single FPIM on the HSIM-F6 to attach to the M port of an FDDI
concentrator.

The HSIM-F6 also supports dual homing. A dual homing configuration
provides additional redundancy for the module or hub containing the
HSIM-F6. Dual homing is a way of connecting to an FDDI ring through
the Master (M type) ports of two separate dual attached concentrators. If
one M type port or one segment fails, the redundant port or segment
activates automatically to retain connection to the ring.

The HSIM-F6 is also capable of operating in full duplex mode, which
creates a point-to-point link between two FDDI devices. This allows for a
data rate of 200 Mbps, with each device transmitting and receiving at
100 Mbps simultaneously.

Bridging
The HSIM-F6 provides translational bridging between any channels or
ports in its host module or hub and the FDDI ring.
