ATM Network Duplication

3-33

With respect to port network connectivity, there is no difference in performance between ATM network duplication and critical reliability. ATM network duplication configurations require

■A simplex SPE complex in the PPN

■Duplicate connectivity over ATM to all PNs

■Duplicate ATM interfaces in each EPN

■Duplicate Tone-Clock boards in each EPN.

An ATM network duplication configuration can be the result of

■A new installation

■An upgrade from a standard reliability system

The EPN configuration for ATM network duplication is the same as for an EPN equipped for ATM critical reliability (Figure 3-9).
