KRONE TECHNIQUES
Patch by Exception
In the world of Network Management systems, the solutions of yesterday are not always the solutions for today.
That is why KRONE Australia, the nations most advanced and progressive connectivity company is introducing
"Patch by Exception", the next generation in cable management systems.
Patch by Exception guarantees network managers a system that is not only flexible, space saving and easy to
manage, but that will accommodate the developing technologies of tomorrow.
WHAT IS PATCH BY EXCEPTION?
Patch by Exception is a product feature of KRONE's HIGHBAND 8 and 10 modules that allows the normal cross
connect configuration to be wired using category 5 jumper cable. Then when a change in configuration is
required the new connection can be simply made by plugging a HIGHBAND patch cord into the module to
instantly set up the new configuration by overriding the jumpered connection. Patching therefore becomes the
exception, and not the rule.
WHY CHANGE TO PATCH BY EXCEPTION?
Historically the RJ45 system provided the IT manager with a no fuss, easy solution to their changing network
needs. Today however, with the number of computers and telephones per office increasing rapidly, many patch
panels have deteriorated into an unmanageable maze of tangled patch cords.
Patching that once took only a matter of seconds to perform, has developed into an increasingly time consuming
and frustrating task; a task that today's busy IT Manager simply does not have the time for. A once welcome
solution has in many situations become an unmanageable hindrance to efficient cable management.
The RJ45 solution has been built on the philosophy of providing data and telephone services to the user, rather
than by supplying a permanent service to a workstation. Traditionally the resulting benefit of this approach has
been that the end user can do all their own moves and changes without the need for assistance from an
installer.
To date this has been achieved by assigning a hub port and an extension port to each individual within an
organisation. If an individual moves location within the office, the Hub port and the extension port are also
transferred to the new location by simply moving the relevant patch cords within the patch panel.
Recently however it has become apparent that it is more sensible to provide a permanent service to a
workstation rather than to an individual. As technology has progressed and the cost of Hub ports and computers
have dropped in price, the provision for computer outlets to workstations is very common. Therefore if a person
moves from one room to another, it is highly likely that data services already exist within that room, and

Meanwhile the routers, switches and hubs, can be located in a 19 inch rack in the air conditioned computer
room, which is the ideal environment for the active equipment. The looming of the patch cords from the hub to
the data side frame contributes to the tidiness of the overall solution, making manageability even easier.
HOW TO GET THE MOST OUT OF PATCH BY EXCEPTION
Many organisations have successfully implemented the Patch by Exception solution by establishing a
maintenance contract with an installer who has progressively removed temporary patch cords on what are now
permanent circuits and replaced them with jumper wire.
Although a maintenance contract is not essential, it can provide the Network manager with numerous benefits.
Most often IT Managers are extremely busy people who have excellent software skills, but a relatively lesser
knowledge of cable management. Generally the person who needs their services moved gives very little notice,
and requires the services changed urgently. The patching is done at the patch frame with little regard to cable
management or the documentation. After a few of these changes are made, the frame begins to look untidy and
large frames become completely unmanageable. With all of their pressing concerns and responsibilities, the IT
Manager is simply not capable of finding the time to tidy the frames and update the documentation. As the state
of the patch frame deteriorates, significant time is lost restoring services and fault finding. For a small monthly
fee the IT manager has an effective and efficient cable management system, and peace of mind. Any changes
required in between monthly calls can be easily administered by the IT Manager in a matter of seconds by using
the patching facility. If these changes are to become permanent the installer can hardwire them at the next
monthly visit and return the removed patchcords to the client for reuse.
THE KRONE HIGHBAND ADVANTAGES
The HIGHBAND modules use KRONE's patented 3 point method of termination which outperforms the
competition in ease of installation, quality, and durability of the connection
• Insulation clamping ribs hold the wire firmly in position and isolate the contact area from vibration and
other forms of mechanical stress.
• Flexible silver-plated contact tags, arranged at 45
o
angles across the axis of the wire, make a solid gas-
tight connection.
• Constant axial and torsional restoring forces, created by the unique contact and plastic housing,
maintain a durable connection that allows up to 200 re-terminations.
