Cascade two IES1248 (Daisy chain mode)
You know, the IES1248 is a remote mini-DSLAM. When the subscriber number is
increased, ISPs may cascade or daisy-chain the more then one IES1248 to extend the
port number. They can daisy-chain up to three IES1248.
How to setup Daisy-chain mode
In this case, we daisy-chain two IES1248. 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
IES1248. Note that we don’t suggest using loop network topology while using
daisy-chain mode.
