DESCRIPTION
The OmniMuxTM400XL is a versatile
multifunction AS400/3X 5250 fiber connectivity unit. It inter-operates
with all of Omnitron?s Omni series products and is ideal for a wide
range of 5250 fiber applications. Being software independent, it is easy
to install and manage. It performs the following functions:
-
Fiber optic star
-
Fiber optic Super multiplexer
-
Fiber optic demultiplexer
-
Fiber optic demultiplexer star
As a fiber optic star, the XL provides per device fiber
to the desk connectivity. On the host end (Link), the star may be
connected to an RJ11/45 or a fiber source. On the device side it connects
to each device via a fiber converter such as the OmniRepeaterTM 400FTD.
As a SuperMuxTM the XL connects
to the host using a DB25 cable and eliminates the Twinax distribution
"Brick". The DB25 cable connects the eight host ports from the
local controller and the XL multiplexes (condenses) these ports into a
single data stream which is then forwarded to eight fiber links. Each one
of the eight links delivers all multiplexed Twinax host ports to a distant
destination via fiber. At the distant location each fiber is connected to
a second OmniMuxTM400 which demultiplexes the ports
to their original host port designation. Based on the application at the
distant end, the far end demultiplexer can be an XL or another OmniMuxTM
converting the ports back to Twinax, twisted pairs or to fiber, for fiber
to the desk applications.
As a demultiplexer, the XL demultiplexes the data
stream received from the fiber link back into 8 host port data streams on
fiber.
As a demultiplexer-star the XL combines
the demultiplexing function with a star function. By selecting a specific
port, that port alone can be selected from the multiplexed data stream and
each of the fibers can serve as an individual device port.
OPERATION
Processing: The OmniMuxTM400XL
utilizes a digital Phase Locked Architecture (PLA). This technology
facilitates reliable data acquisition with data rate variations of -2% to
+4%. This facilitates consistent connectivity with all IBM and compatible
devices and host models. It also facilitates a high degree of noise and
crosstalk immunity.
The XL monitors all incoming data streams
simultaneously, checking for data activity and errors. Once the valid data
frame is recovered, it is processed and checked. True data activity or
errors are displayed for each link using LED displays thus helping in
monitoring network operation and problem isolation.
When a valid data frame header is recognized, the data
frame "Cuts Through" and is retransmitted. It is fully
regenerated and restored to its full original amplitude, and any lost
start bits are reconstructed and regenerated. Each data bit is reshaped
and reclocked at a 50% duty cycle eliminating any clock jitter and
ensuring reliable connectivity.
Inputs and Outputs: The OmniMuxTM400XL
features the following inputs and outputs:
-
Host ports 0-7 for host DB25 connection
-
Link 0 for host side RJ11/45 copper connection
-
Link 1 for host side ST fiber connection
-
Port-Link 0-7 for ST fiber connection to distant
multiplexers or to local stars or devices
In SuperMuxTM mode, the DB25 host
ports 0-7 connect to the host?s workstation controller and replace the 8
port Twinax "Brick". On the far side, the Port-Links 0-7 connect
to far side demultiplexers.
In demultiplexer mode, Link 0 (copper link) or Link 1
(fiber link) connect to a host side multiplexer. On the far end,
Port-Links 0-7 connect to far end stars.
In star mode, Link 0 or Link 1 connect directly to a
workstation controller (via a balun or a fiber converter), or to a
demultiplexer. Port-Links 0-7 connect to Twinax devices via fiber
converters such as the OmniRepeaterTM400FTD.
In demultiplexer-star mode, Link 0 or Link 1 connect to
a host side multiplexer. On the far end, the Port-Links 0-7 connect to
individual devices via fiber converters.
