3.6 Point-to-Multipoint Operation
3.6.1 Introduction
With point-to-multipoint operation it is possible to aggregate several low-bitrate
DSL links into few E1 systems. This allows concentration of DSL links carrying
small traffic loads on fewer E1 interfaces, saving resources in the E1 transport
network. Multipoint operation on a single plug-in allows to concentrate up to 4
DSL links to a single E1 interface. Multipoint plug-ins can also be cascaded for
even higher concentration factors.
Multipoint operation is compatible with multiservice and mixed mode operation.
Figure 3-16 shows some examples of multipoint configurations. The cascading of
plug-ins to increase the number of links is shown in configuration c).
