Øsubtending§ connecting multiple ISAM systems (7302 CO or 7330 host)

via Ethernet subtending links§ standalone nodes: each node provides the Ethernet switch and aggregation

function and is managed separately

Øexpansion§ connecting ISAM host shelf (7330 only) with remote LTs,

via expansion links (optical)§ switch and aggregation function in host shelf only§ one system: host shelves are managed together as a single system
