Unbundled Network Element (UNE) Non-Recurring Cost Study
*..
Field Work
This section addresses the costs of the non-recurring activities to install, change, and
disconnect
UNEsAJNE-Ps
in the field (outside plant) and central office. Outside plant
work is any non-recurring activity on the facilities between the central office and the
customer’s premises. This includes any cross-connect activity at the FeederDistribution
Interface (FDI), cross-connect box, pedestal or pole, and Network Interface Device
(NIDI.
Central office activities include runninghreaking jumpers on
the
Main Distribution
Frame (MDF), Intermediate Distribution Frames (IDFs), and Tie-Cable Frames. The
Central Office Technicians are responsible for orders in the host office, as well as, remote
offices.
Installation Cost Methodoloqv
,--
The cost team documented the installation process flows for outside plant and central
office. (See Appendix Tab
1
for Process Flow Diagrams.) The process flows address
system enhancements that will modify work done by these groups. The cost team also
accounted for Express Dial Tone (EDT) and Left-in-Jumper (LIJ) when they determined
the probability of cross-connect and jumper activity.
The installation UNE/UNE-P NRCs were developed from time and motion studies,
system reports, order volumes, workgroup hours and Subject Matter Experts (SME)
estimates. The cost team used the most current loaded labor rates for each of the
workgroups. (See Appendix Tab
6
for Loaded Labor Rates.) The cost team calculated
the installation costs for each type of
UNE
order using the standard non-recumng cost
calculation
