Unbundled Network Element (UNE) Non-Recurring Cost Study

Central Office Technicians, testing and assignment personnel is not available from

analogous services in the Retail market. The costs reflect estimates of the field

installation time for a standard interval (base case) and for additional intervals of time

when the conversion extends beyond the standard interval.

Central Office Activitv

In the manned central offices, Central Office Technicians rudbreak the fiame jumpers.

Depending on the location of remote offices, a Central Office Technician or a CZT/BZT

will complete the jumper work. Central Office Technicians download “Jumper

Run

Lists” from

AAIS;

the lists identify

all

instructions for running or breaking frame jumpers

to complete the UNE/UNE-P orders.

All inward and outward unbundled loops and ports require frame work. The time to run

or break a jumper depends on the type of frame, the length of the frame and the physical

location of the equipment. The cost managers used the “Jumper Study” and the “Drive

Time Study” to calculate the central office costs for each type of

Data Collection

The cost team and

Arthur

Andersen personnel conducted time and motion studies to

determine the activity times for all of the central office work for UNEs. Study personnel

observed and timed with a stopwatch the jumper activity in ten central office locations for

the period of one week. The central offices were chosen to provide a mix of size, frame

types,

and host vs. remote activity. To develop the average time to

run

a jumper in the

host office, the observers included all jumper activity for inward orders on the jumper run

list; for disconnects ofjumpers, they included all jumper activity for outward orders.

A separate study was conducted to determine drive times for service order activity in

remote offices. The observer calculated the percentage of time spent at the remote

running or breaking jumpers versus other all other central office work. This percentage

was then applied to the total drive time to the remote. To determine jumper run times for

remote offices, the observer included an allocation of drive time to the remote location.

Using the number of access lines for the manned and unmanned offices, the cost team

computed a hosthemote ratio and then weighted the average time to

run

a jumper at a

manned vs. unmanned location. This results in a single weighted average jumper time.

The average jumper time is used in the per-line cost calculation for each type

UNE/UNE-P.
