WBC with WCC connected over MSIL to CP network OR IPS-C with WCC connected over MSIL to CP network CDD CP Network MSAN/ DSLAM BRAS MSIL WBC + WCC or IPS-C + WCC
WBC / IPS-C in PTA Mode CDD CP Network End user connection (PPP session) MSIL MSAN/ DSLAM BRAS WBC + WCC or IPS-C + WCC In PTA mode, the end user connection (tunnel) ends on the BRAS and at that point the traffic can make a decision. Most traffic will come from the Internet via the CP’s network but there is the choice to select some traffic from CDD (the wCC video storage).
WBC / IPS-C in L2TP Mode CDD CP Network End user connection (PPP session) MSIL MSAN/ DSLAM BRAS WBC + WCC or IPS-C + WCC In L2TP mode, the end user connection (tunnel) continues through the BRAS and into the CP’s network and it is only at the end point of the tunnel that the traffic can make a decision. In this L2TP mode the end user’s tunnel bypasses the decision-making process in the BRAS so traffic cannot be inserted from CDD (the wCC video storage).
