FREQUENTLY ASKED QUESTIONS
What is Jumper Cable?
Jumper cable is the same as 4
pair solid conductor building
cable. This means that its
transmission performance is
the same as regular
horizontal cable.
With jumpered connections you only use as much
wire as you need. Therefore, a jumpered
transmission path will always be shorter than a
patched path. A jumpered solution also has lower
loss and lower crosstalk as well as a neater
appearance.
What is Patch-By-Exception?
This is a product feature of HIGHBAND 8,
HIGHBAND 10, HIGHBAND 25 and Ultim8 that
allows the normal cross connect configuration to be
wired up using jumper cable. When a change in
configuration is required the new connection can
simply be made by plugging a HIGHBAND patch
cord into the module. This instantly sets up the new
configuration by overriding the jumpered
connection. Some of the advantages of Patch-By-
Exception with HIGHBAND are:
- Lower cost due to the economy of using jumper
cable instead of patch cords.
- Any temporary patches are easily seen by the
network administrator increasing control and
record accuracy.
- The normal connection configuration can be

restored simply by removing the patch cord
- Neat and tidy cable management due to
elimination of patch cord slack. Lower
transmission loss.
- Easy removal of jumpered patches (no plug or
locking tab to snare on other patches)
- Eliminates potential user damage to modular
patching such as bent patch panel pins, cord
fracture or failure due to tightness or tangle, and
plug locking tab breakage.
- If temporary patches are to become permanent,
they can be replaced by jumper cross connections
when convenient. The removed patch cords can
be kept handy for future use.
Does HIGHBAND have a
disconnect test facility?
Yes. The HIGHBAND 8, HIGHBAND 10,
HIGHBAND 25, Ultim8 and Compact 8
modules use a disconnect contact allowing test
access to a circuit without breaking the circuit or
removing wires. You can also leave
jumpers in place and patch the
same circuit to another port (i.e.
Patch-By-Exception).
Why use HIGHBAND instead
of RJ45 patch panels?
There are many reasons why
you would choose
HIGHBAND over RJ45
patching. Refer to the technology

comparison HIGHBAND vs RJ, document
under the HIGHBAND tech-tips area on this CD-
ROM.
What advantages does HIGHBAND provide
that a 110 system will not?
There are many. Refer to the technology
comparison HIGHBAND vs 110 Type, document
under the HIGHBAND tech-tips area on this CD-
ROM.
Does my standard KRONE tool terminate
wires on HIGHBAND?
Yes. HIGHBAND has been designed to be compatible
for use with the existing KRONE Termination Tools.
Why use HIGHBAND 16
and 20 Modules?
When high density
patching is considered
more important than the
disconnect or jumpering
facility, HIGHBAND 16
and 20 modules may be
more appropriate than
HIGHBAND 8, 10 and 25
pair modules.
