Figure 5:
TDM Pipes
Bandwidth Partitioning Examples
At any given JungleMUX node, a TDM pipe is considered “accessed” if:
-
all of its STS-1s are assigned to the matching TDM pipe in a local
ETHER-1000 unit;
-
the TDM pipe is provisioned in the local ETHER-1000 unit (set for the
proper topology mode);
-
at least one of the local ETHER-1000 paddleboard ports has been
provisioned to use a VLAN associated with this TDM pipe.
In the example in Figure 6, each of the four TDM pipes is accessed at all sites.
Since all four pipes have been configured as rings, protection switching is
independently carried out for each TDM pipe. Also, the total amount of STS-1s
used for all 4 pipes cannot exceed 24, which is the limitation imposed by the
ETHER-
1000 unit‟s Line port capacity.
