Cascade two IES-1248-51V (Daisy chain mode)
You know, the IES-1248-51V is a remote mini-DSLAM. When the subscriber number
is increased, ISPs may cascade or daisy-chain the more then one IES-1248-51V to
extend the port number. They can daisy-chain up to three IES-1248-51V.

How to setup Daisy-chain mode
In this case, we daisy-chain two IES-1248-51V. Please see the figure above. We only
set the one connected to the ISP as Daisy-Chain mode. In Daisy-Chain mode, connect
the Ethernet Port 1 to the Ethernet backbone and connect the Ethernet Port 2 to
another IES-1248-51V. Note that we don’t suggest using loop network topology while
using daisy-chain mode.
