deload the cable pair. The outside plant construction splicing group will work the order
and advise the engineering group upon the completion of the activity. The engineering
group will then advise the service office the order can be worked
as
requested. All
records are updated showing the change in the loading of the pair.
Bridged Tap Removal
Bridged tap is when a cable pair count branches off to serve various locations.
These branches provide flexibility in the use
of
the cable pairs. The bridged taps
have a negative affect
on
the transmission
of
high frequency signals. The bridged
tap does not affect voice grade signals. This method
of
provisioning copper voice
grade service has been an accepted method by all telecommunication companies
for
years.
When the CLEC requests a conditioned loop that requires all the cable pair bridged taps
to be removed, the engineering department is advised and the outside plant engineering
records are examined to determine the location of the bridge taps.
A
work order is
created to remove the bridged taps and is sent to the outside plant construction work
group.
A
construction cable splicer is assigned to the activity and the pair is cleared of
the taps. When the work order is complete both the engineering group and the service
office are notified that the CLEC request can be completed.
The costs for removing bridged taps were determined in the same manner
as
the load coil
removal. Outside plant engineering and construction support
SME’s
in conjunction with
field forces determined the activities and the time required to perform the removal.
In
addition it was necessary to determine the number of bridged taps that may need to be
removed. This
was
determined by acknowledging that the minimum number of removals
would be one, and the maximum number is
unknown.
To determine the maximum
number it would need to be at least two, more than one, and could be three or more. A
conservative estimate is to average the minimum of two and three, which results in
an
average of
two
and one-half.
Method
of
Calculation
Load Coils
The first criteria used in determining the cost of removal
is
to ascertain the footage of
aerialhuried cable and underground cable. This is done because of the differences in the
amount of time for the load coil removal in the various types of outside plant. The time
for removal is then weighted by this calculation.
Load coils are placed
on
copper voice grade loops based on their distance from the
central office. The load coils are placed at engineering distances to develop the
maximum result. Therefore, as the footage of the cable increases from the central office
the number of load coils increase proportionally. The use
of
cable footage is then used to
determine the number of loads to be removed.
An
inventory of cable lengths is then
