All new D3 tiers 50/10 and soon to be Ultra (22/5) new installs will probably have the Motorola 6120 to be installed.

www.motorola.com/Busines ··· 20_US-ENOur eastside market already has 50 of these 6120's in, hot roll out on Tuesday...
Otherwise if anyone is upgrading to the 22/5, any D2 compatible modem will be just fine.
