It seems that Maxwell is limited to two 10/100/1000 Ethernet interfaces, so you have no solution for introducing impairments for DS3, E3, OC-3, and OC-12?
The other physical interfaces are not required. Nearly all clients and servers are Ethernet based. When they connect to other high performance networks with higher speed media, they nearly always do so via a router. Maxwell does not require a physical interface to a particular type of media to track and impair sessions traversing that media.
