Chapter 14 xDSL Profiles Setup

"Traffic shaping must also be enabled on the subscriber's device in order to use upstream policing.

Note that since the IES-612-51A uses ATM QoS, if the subscriber device's upstream shaping rate is larger than the IES-612-51A's upstream policing rate, some ATM cells will be discarded. In the worst case, none of the Ethernet packets from the CPE will be able to be reassembled from AAL5, so no packets from the subscriber's device can be received by the IES-612-51A.

The upstream policing feature can be enabled/disabled per PVC. No matter which ATM traffic class is used for the PVC's upstream traffic (CBR, VBR, or UBR), the IES-612-51A will drop any upstream traffic that violates the specified ATM VC profile.
