+Verify that non-assured BW is released to assured BW allocation as needed for TT
+ [Documentation] Verify support for Tcont type 2 and 3.
+ ... Pump 1Gbps in the upstream from RG of ONU2 for VoD service and
+ ... then verify that no more than 700Mbps is received at the BNG.
+ ... Firstly, pump 500Mbps from the RG of ONU1 for the VoD service and
+ ... then verify that close to 500Mbps is received at the BNG.
+ ... Also verify that the VoD rate is now truncated to 500Mbps at BNG for ONU2.
