In the following scenarios examples for four layer point configurations are shown. In these
figures a switch with its incoming and outgoing port is represented by the symbol shown in
ILJXUH .

The PXB 4340 AOP can be configured according to its location in the network as shown in the
following examples.
Within a pure ATM network VPCs may be originated or terminated. In addition VP segments can
be originated or terminated as shown in ILJXUH .

As VPCs are always terminated at an ingress port and originated at an egress port, the
functionality of the PXB 4340 AOP is restricted accordingly. For example it is not possible to
terminate VP-AIS cells at the egress port of a switch. 7DEOH  shows an overview over all
possible layer points.
VCCs are not originated or terminated within a pure ATM network, but only VC segments
(ILJXUH ).
