 PVC Settings: VPI is the virtual path between two points in an ATM network and
its valid value is from 0 to 255. Default value is 8.
 VCI is the virtual channel between two points in an ATM network, ranging from 32
to 65535 (0 to 31 is reserved for local management of ATM traffic). Default is 35.
 Service Category: Select one of the following values from the drop-down list -
UBR Without PCR, UBR With PCR, CBR, Non Realtime VBR or Realtime VBR.
 Protocol: Select one of the following values from the drop-down list – Bridging,
PPP over ATM (PPPoA), PPP over Ethernet (PPPoE), MAC Encapsulation
Routing (MER), IP over ATM (IPoA).
 Qos scheduler: You can select between either Strict Priority or Weighted Fair
Queuing. QoS Scheduler provides for two options of bandwidth management
that can monitor the importance of data packets and depending upon the priority
of the packet, give it higher or lower priority or bandwidth level.
Strict Priority Queuing (SPQ) - queues are assigned a priority order and served
strictly according to that order. A low-priority queue may be starved if there are
always packets in higher-priority queues.
Weighted fair queuing (WFQ) - queues are each assigned a weight, and they
share the bandwidth of the port according to that weight.
Based on network calculus the DSL-2750U can build analytical models for traffic
flows under SPQ and WFQ scheduling.
 Encapsulation Mode: Select the method of encapsulation provided by your
ISP.Select an option from the drop-down list – LLC/SNAP-Bridging, VC/MUX.
