As I recall from my reading of "the standard", there's nothing in there to  
prevent any tunneling on top of the DOCSIS bridged ethernet.

I suspect this is not a "standard" problem but an ISP problem... their new  
hardware doesn't support PPPoE/L2TP, it's an additional license, or they  
don't know how (or unwilling) to configure it.

(I'm assuming the PPPoE is between you and the customer, and L2TP is  
between your network and the cable network. i.e. L2TP is how your  
customers are brought to you from the cable network.)

I have no documentation on ARRIS either, so I don't know what they  
can/cannot do.
