SynOptics Communications' Lattis System 5000(tm) Token Ring host
modules deliver state- of-the-art connectiviguration and
management capabilities for System 5000 network center
applications.  Occupying a single slot in the Model 5000 chassis
and featuring IEEE 802.5 Token Ring compatibility, the Token Ring
modules deliver advanced solutions for building structured Token
Ring network environments.

THE SYSTEM 5000 SOLUTION
SynOptics' LattisSphere(tm) System 5000
represents the industry's first product family aimed at
delivering a structured networking solution for today's legacy
networks while providing an opeath to future LAN technologies.

The Model 5000 is designed to support highly-segmented enterprise
networks by providing a central point of integration and
administration for distributed environments.  Residing in the
network center, the Model 5000 unites distributed Lattis System
3000- and Lattis System 2000- based Ethernet, Token Ring and FDDI
networks as a single, cohesive system, optimizing the use of
centralized network resources such as servers, bridges and
routers.

The Model 5000 also includes a built-in path to the
high-speed switching technologies of the future, enabling
customers to incrementally evolve their shared-media LANs to
switched backbone networks without sacrificing existing
investments.


TOKEN RING MODULE OPERATION
The System 5000 Token Ring host
modules deliver complete connectivity solutions across a wide
range of unshielded twisted pair and shielded twisted pair media.
Occupying a single slot in the hub, the modules can operate at
either 4 megabits per second (Mb/s) or 16 Mb/s over one of nine
Token Ring data paths on the Model 5000 backplane, delivering
unprecedented configuration flexibility for dynamic applications.

All System 5000 Token Ring host modules include built-in
automatic frequency-detection hardware, which prevents a Token
Ring device from entering the network at the wrong speed.  If a
data-rate mismatch is attempted - such as a 4 Mb/s device
connecting to a 16 Mb/s ring - the frequency detection circuitry
automatically wraps the port, avoiding potential beaconing or
alarm conditions on the network.

Three System 5000 Token Ring host modules are available:
the Model 5575-F Token Ring Intelligent Dual Cluster Repeater Host
Module, the Model 5505P Token Ring Active Retiming Host Module and
the Model 5502 Token Ring Passive Host Module.


MODEL 5575-F TOKEN RING INTELLIGENT DUAL CLUSTER REPEATER HOST MODULE
The Model 5575-F Token Ring Intelligent Dual Cluster
Repeater Host Module provides distributed SynOptics workgroups
with full access to centralized resources located in the network
center.

The Model 5575-F features two sets of duplex ST fiber
connectors to support Ring-In/Ring- Out trunk connections to
System 3000(tm) and LattisRing(tm) System 2000(tm) Token Ring workgroups
distributed throughoutrprise.  The ports provide
connectivity for users located up to 2 kilometers away over
62.5/125 m and 50/125 m fiber optic cable.  Full repeating
functions are implemented on receive and transmit pairs for both
primary and secondary ring paths.

Each Ring-In/Ring-Out trunk connection is associated with a "cluster"
consisting of three RJ-45 copper lobe ports, providing efficient access to
centrally-located file servers, bridges and routers over
readily-available shielded and unshielded twisted pair cabling.
Each cluster can be assigned to any of nine Model 5000 backplane
ring paths through software control, providing considerable
flexibility for configuring the network.  The clusters can
alternatively attach to the local module-level ring, which is not
connected to the backplane, or they can be removed entirely from
both the module-level and backplane rings to establish
independent, isolated clusters in the network center.
Module-level and isolated rings provide core management
capabilities which allow network managers to monitor hub hardware
status, control hub configuration and obtain simple network
performance statistics.

A third port, called the Monitor Port, offers a single front-panel
RJ-45 modular receptacle for attaching network diagnostic equipment
in the network center. The equipment can be used to evaluate individual ring
performance, using either front-panel push-button controls or via
the network management system to select the desired ring number
and speed.

Each Ring-In/Ring-Out trunk port on the Model 5575-F
also includes a built-in Frame Processing Unit (FPU) to provide
the network management system with sophisticated ring diagnostic
information.  The FPU provides data such as frame counts, soft
error counts, and Upstream Neighbor Address (UNA) notification to
aid in network management and the port association process.


MODEL 5505P TOKEN RING ACTIVE RETIMING HOST MODULE
The Model 5505P Token Ring Active Retiming Host Module offers 20 RJ-45
modular receptacles to support 4 Mb/s and 16 Mb/s Token Ring host
stations over both shielded and unshielded twisted pair cabling
on the same ring.

Each port can be individually assigned to any
of the Model 5000 backplane rings or to the module-level local
ring, giving network managers complete flexibility in configuring
the network to meet their specific requirements.  The module also
incorporates data signal active retiming and regeneration on each
lobe port, thereby reducing system jitter and signal loss to
maintain highly-reliable performance over all twisted pair
cabling types.

The Model 5505P can be used to create single rings
supporting up to 132 devices over a variety of structured
cabling.  The module supports lobe lengths up to 200 meters at 4
Mb/s and 100 meters at 16 Mb/s over Category 3 voice-grade
unshielded twisted pair cabling, also known as D-Inside Wire
(DIW).  Lobe lengths of 300 meters (at 4 Mb/s) and 160 or 180
meters (at 16 Mb/s) are supported over high-grade, low-crosstalk
Category 4 and Category 5 unshielded twisted pair cabling,
respectively.

For shielded twisted pair cabling environments, the
Model 5505P supports lobe lengths of 600 meters (at 4 Mb/s) and
300 meters (at 16 Mb/s) over Type 1, Type 1A and Type 2 shielded
twisted pair cabling; 400 and 200 meters (at 4 and 16 Mb/s) over
Type 6 and Type 9 shielded twisted pair cabling; and 300 meters
(at 4 Mb/s) and 150 meters (at 16 Mb/s) over Type 8 shielded
twisted pair cabling.


MODEL 5502 TOKEN RING PASSIVE HOST MODULE
The Model 5502 Token Ring Passive Host Module offers 24 RJ-45 modular
receptacles to support Token Ring host stations operating at 4 or 16 Mb/s over
shielded twisted pair cabling and high-grade, low-crosstalk
Category 4 and Category 5 unshielded twisted pair cabling.

The Model 5502 provides a compact solution for high-density network
environments.  All 24 ports are connected to the same ring, which
can operate over one of the nine Token Ring paths on the Model
5000 backplane or on the local module-level ring.  The Model 5502
can be used to build individual Token Ring networks supporting a
maximum of 250 devices over shielded twisted pair cabling or 132
devices on unshielded twisted pair.

The module supports lobe lengths up to 200 meters at 4 Mb/s and
100 meters at 16 Mb/s over Category 4 and Category 5 unshielded
twisted pair cabling, and 100 meters at 4 Mb/s over Category 3 DIW.
Lobe lengths of 350 meters (at 4 Mb/s) and 180 meters (at 16 Mb/s)
are supported over Type 1, Type 1A and Type 2 shielded twisted pair cabling.
The module also supports lobes of 200 and 120 meters (at 4 and 16
Mb/s) over Type 6 and Type 9 cabling; and 150 meters (at 4 Mb/s)
and 90 meters (at 16 Mb/s) over Type 8 cabling.


ADAPTER CARD COMPATIBILITY
The Model 5575-F, Model 5505P and Model 5502 have all been successfully
tested for compatibility with IBM 16/4 Token Ring adapter cards, allowing
for seamless integration of existing IBM/SNA networks into System 5000
environments.


TOKEN RING MODULE MANAGEMENT
System 5000 Token Ring modules are fully integrated into the SynOptics
Optivity(tm) network management system, enabling network managers to monitor
and control network activity from a central management station.  Management
data is forwarded to the network management system overhigh-speed,
out-of-band Common Management Bus (CMB) on the Model 5000
backplane, ensuring rapid and timely reporting of network
performance.

The Token Ring modules appear in the Expanded View(tm)
graphical user interface, providing unprecedented visibiy into
the network topology.  A variety of other views are also
available, including the new Network Center View, which
introduces a new method for managing and configuring the
enterprise network from a central management station.


LED INDICATORS
Each System 5000 Token Ring module includes a
comprehensive front-panel LED display matrix to indicate module
performance and configuration at a glance.

The Model 5575-F includes a module-level LED to indicate overall module
status, as well as separate LED fields for the various cluster ports.  The
LEDs report which backplane rings the clusters are assigned to,
the various ring speeds and whether the clusters are local or
isolated from the backplane.  Other conditions, such as
beaconing, wrapping or the presence of a phantom signal, are also
reflected on a per-cluster basis on the LED matrix display.

The Model 5505P and Model 5502 include an overall module-status LED,
as well as a series of indicators to report individual ring and
port status.  One field indicates which ring or rings on the
backplane are being utilized by the module or by individual
ports, and the status of those rings.  A second field offers a
series of port-level indicators to report the presence of a valid
phantom signal or whether the port is wrapped.
