If you mean the Adit 600, any ethernet handoff will do but you might need a crossover cable depending on the application. The CMG cards are "ok" really but I'm not a huge fan of the adit. Make sure you have the latest cmg code.
Just also know that it DOES require MGCP as the Adit does not support SIP trunks yet and it also doesn't support FXO as of yet from what I read below. (Can you do MGCP with Asterisk?)
I should also warn you that from my experience, Carrier Access doesn't think on the IP level very well. They are a voice company first with data thrown in because they felt they had to.
Just so you also know, the Adit 600 doesn't even have a way to keep time/date info in a reboot or loss of power scenario. To me it's a design flaw but they insist it was a cost saving measure. At least that's what I was told.

o excellent gear perfect with Asterisk
o FXS Interfaces: supports callerid and callwaiting, doesn't seem to support callwaiting callerid, someone correct if this is wrong.
+ CMG card provides an Ethernet MGCP interface as an alternative to T1.
+ NOTE: CMG card ONLY supports FXS at this time!!!
