You can configure multiple logical links over the same physical port. However, you can
only configure one logical link (using one pair of ATM ports) for each ATM
cluster-to-cluster or subnetwork-to-subnetwork connection.
Using Static Routes
In an ONcore/CELLplex 4000 ATM network, you can only set a logical link to a cluster
number (ACN) that is defined within your own ATM subnetwork. In order to set up a
logical link with a remote cluster outside your own subnetwork, you must use the SET
STATIC_ROUTE command to assign an ACN to the network prefix of the boundary hub
of each remote cluster to which you want to link. The SET LOGICAL_LINK command
then will be able to set up a connection to this logical hub using its assigned ACN.
Trunks Within a Single Cluster/Subnetwork
To define a logical link between switches within the same cluster or subnetwork, use the
SET LOGICAL_LINK command to set the following parameters for each port in each
switch:
Virtual Path Identifier (VPI) number
ATM cluster number (ACN) for the remote switch
Bandwidth available on the virtual path
Signalling role for Q.2931 protocol.
