interconnection”; “Separation of accounts for specific activities”; “Price control and cost
accounting” (e.g. set cost oriented prices and retail-minus) and “Financial Reporting”.
e) To date, prices of bitstream and associated resources have been regulated according to
the principle of cost orientation of prices and retail-minus. As with LLU, ANACOM has
based its estimates of costs on the analytical accounting system of PTC and the budgeted
costs and the current costs of resources consumed and activities needed for the provision
of services; and also with reference to practices in the European Union.
f) The prices are cost oriented (and retail minus for specific offers). No upfront payments or
volume discounts exists.
g) In the “NGA consultation”, ANACOM concluded that in non-competitive areas it is not likely
that access to the local sub-loops will be a viable solution, as neither was access to the
local loop. In these cases the most appropriate and priority solution appears to be virtual
access to the network, i.e., advanced bitstream.
Regarding the “technical evolution” (of the SMP‟s network), ANACOM noted in the same
document that “a possible first step towards the adaptation and preparation of [the
bitstream offer] with respect to the evolution seen in networks and services over the short
and medium term may be:
� Extension and flexibility of Ethernet aggregation with respect to the entire offer, i.e., an
extension of coverage with Ethernet technology to all exchange areas, with particular
relevance for those areas not currently covered by the LLU beneficiary operators and
whose coverage in the future by NGA will probably see (most) delay.
� Addition of flexibility to the offer of local access and logical Ethernet connections, in
particular in terms of establishing classes of service/VLAN and QoS mechanisms, or
others.”
Below, some additional questions on bitstream:
� Please describe the different points of access available (e.g. at the broadband PoP, MDF)
and the layers (layer 2, 3 )
See b) above.
� Is quality differentiation possible and how is it implemented? Please mention the relevant
quality parameters and state whether guaranteed bandwidth is available.
Yes, if the traffic aggregation is done at Level 2, i.e., using ATM or Ethernet aggregation.
For example, using different VLANs with different QoS. Guaranteed bandwidth is also
available in the cases of using ATM (CBR).
