Zu Deutsch: Es gibt mehrere Gruppen von Adernpärchen. Hier im gezeigten Bild sieht man z. B. ein Bündel mit 101 Adernpaaren weiß-rot, welches gerade gespleißt wird. Das Kabel selbst hat 1500 Paare. Dabei sind die Paare im Kabel gerade mal zu größeren Bündeln gruppiert. Die einzelnen Adern sind nicht merkiert und es muss jedes einzelne Adernpaar mühsam herausgeprüft werden, bevor es gespleißt wird. Das ist doch bescheuert. Da sitzt man ja eine Woche an so einem Kabel dran.Many Telecom readers are, to some extent, familiar with the
color code used on polyethylene insulated cables (PIC) in which each
pair is individually color-coded and arranged in groups of 25-pairs,
with these groups in turn being identified with colored binder
strings. The above color code uses ten colors, and begins with
white/blue for pair 1, white/orange for pair 2, white/green for pair
3, etc., ending with violet/slate for pair 25; binder group
identification is made with colored tape or string using the above ten
colors. The complete color code has already been posted by others to
Telecom, and it is not my intent to repeat it here.
The above color code with individual pair identification is
used on both inside station wiring and outside PIC distribution cable.
However, pulp-insulated cable does NOT have identification of
individual pairs. There is still a significant amount of
pulp-insulated cable in service, especially with high pair counts of
1,500 to 2,700 pairs.
Pulp-insulated cable uses only three pair colors: white/green,
white/red and white/blue. Binder groups within the cable come in
sizes of 25, 26, 50, 51, 100 and 101 pairs, depending upon the wire
gauge, pair count and style of the pulp-insulated cable. For cables
with 400 or more pairs, the binder group size is generally 100 or 101
pairs.
Each of the pairs in such a binder group has the SAME color
code! As an example, a 404-pair pulp-insulated cable will typically
have four binder groups: (1) 100 pairs of white/green plus a red/blue
tracer pair; (2) 100 pairs of white/red plus a red/blue tracer pair;
(3) 100 pairs of white/blue with a red/blue tracer pair; and (4) 100
pairs of white red with a red/blue tracer pair. The total pair count
in this example is 404 pairs, and note that there are 200 pairs which
have a white/red color code. The tracer pairs are generally reserved
as spare or maintenance pairs.
To make matters even more confusing, many pulp-insulated
cables have no binder strings or tape! The binder groups have a twist
which allows their identification as a unit, and the relative position
of the binder groups when the cable is viewed in cross-section allows
the identification of the particular binder group. Such binder groups
are therefore arranged in concentric layers, with each layer being
divided into binder segments. There are also umpteen different binder
coding schemes used for pulp-insulated cable. For the sake of
simplicity, while I am using the term "binder group" in this article,
in reality I am referring to a cable "unit", which may in fact not
have any binding strings or tape.
As a result of the above, believe me, a damaged pulp-insulated
cable is a real mess! Also, bear in mind that PIC cable did not come
into general use until the 1950's, so prior to that time
pulp-insulated cable was the ONLY type of outside plant cable.
Restoration of a damaged pulp-insulated cable is performed by
tone tracing or other electronic identification means on EACH AND
EVERY pair. Restoration starts by picking a red/blue tracer pair as a
means of establishing telephone communication between the cable
splicer and the central office. At least there aren't that many
tracer pairs to choose from. :-)


Das hat jeder schon mal gemacht, hat sich bewährt.(Und das mit der Coladose habe ich auch mal vor Ewigkeiten bei einem Kadett gemacht auf die Schnelle.



Nachdem aber irgendwann auch vom Rest des Auspuffs nicht mehr viel uebrig war und ich diesen ersetzen durfte hab ich dann auch wieder die richtige dafuer vorgesehene Halterung verwendet.
