Figure 3: ATM VLL for End-to-End ATM Service
ATM VLLs (Apipe) provide a point-to-point ATM service between users connected to 7750 SR
nodes on an IP/MPLS network. Users are either directly connected to a 7750 PE or through an
ATM access network. In both cases, an ATM PVC (for example, a virtual channel (VC) or a
virtual path (VP)) is configured on the 7750 PE. This feature supports local cross-connecting
when users are attached to the same 7750 PE node. VPI/VCI translation is supported in the ATM
VLL.
