� Available for all DSLAM ADSL, ADSL2 and SDSL and ISAM VDSL2 at 5 regional
points of interconnection and at MDF level. Difference between Dedicated and Shared
VLANs and different p-bits for quality of service differentiation.
� The Belgian WBA VDSL2 bitstream offer includes:
� The possibility to give premium clients their own private network with dedicated
VLANs and symmetric profiles, while for mass market purposes, shared VLANs and
asymmetric profiles with different download speeds are available.
� Different QoS levels: P=0 (best effort), P=1 (low priority), P=3 (medium priority), P=5
(highest priority) and P=6&7 (control functions). Two VLAN per QoS level can be
ordered per OLO.
� The size increments of VLANs are chosen small enough so that the costs don‟t
decrease disproportionally when a bigger VLAN is needed.
� Flexible interconnection at regional (5 areas) & local level (MDF). 5 points of
interconnection needed to obtain national coverage.
