* A national network which connects the main distribution frames
to national access points, entailing substantial investments.
As outlined above the regulation of wholesale products so far and especially the differentiation between core and access network has relied on the EU commission's view of 1998 that the split between core and access takes place in the main distribution frames
. If the main distribution frames
are being replaced respectively if the roll-out of fibre in the local loops makes the street cabinets the central points for wholesale access products, it will also be necessary to recalculate the prices of regulated wholesale products.
The model applied here, however, is based on GIS data for the main distribution frame
locations and thus automatically accounts for topology and the respective geographic distribution of demand.
It included all cabling needed to carry data and voice circuits from a main distribution frame
(MDF) to terminal locations, or "drops," on two floors of the building.
Intrabuilding hardware is used in the main distribution frame
at the building entrance, riser wiring closets, floor and satellite wiring closets, and in the workstation area.
From the main distribution frame
(MDF) on the lower level, riser cables run to 42 intermediate distribution frames (IDFs) on each floor of each of the nine interconnecting buildings.
