EAN Redundancy
EAN redundancy is ensured by connecting the two Ethernet ports of the IP
DSLAM to each ECN330/ECN320, as illustrated in Figure 11 on page 20.
Redundancy requires enabling of Rapid Spanning Tree (RSTP) in both of
the ECN330/ECN320.

The two ports of the IP DSLAM can also be used to enable link bandwidth
of 200 Mbps to a single EDN312x.
