Field Name Description
Link Type [EoA] Ethernet over ATM
[PPPoA] Point-to-Point Protocol over ATM
[IPoA] Internet Protocol over ATM
Encapsulation Mode [LLC/SNAP-BRIDGING] Logical Link Control used to carry multiple protocols in a single PVC (Permanent
Virtual Circuit).
[VC/MUX] Virtual Circuit Multiplexer creates a virtual connection used to carry one protocol per PVC
(Permanent Virtual Circuit).
Service Category [UBR without PCR] Unspecied Bit Rate with no Peak Cell Rate, ow control or time synchronization
between the trac source and destination. Commonly used with applications that can tolerate data /
packet loss.
[UBR with PCR] Same as above but with a Peak Cell Rate.
[CBR] Constant Bit Rate relies on timing synchronization to make the network trac predictable. Used
commonly in Video and Audio trac network applications.
[NON Realtime VBR] Non Realtime Variable Bit Rate used for connections that trans-
port trac at a Variable Rate but need to have a guaranteed bandwidth and latency. This
category does not rely on timing synchronization between the destination and source.
[Realtime VBR] Realtime Variable Bit Rate. Same as above but relies on timing and synchronization
between the destination and source. Commonly used in networks with compressed video trac.
Minimum Cell Rate [cells/s] (-1 indicates no shaping)
Minimum allowable rate at which cells can be sent on a ATM network.
Scheduler for Queues
of Equal Precedence
as the Default Queue
The algorithm used to schedule the queue behavior.
[WRR] Weighted Round Robin packets are accessed in a round robin style and classes can be given.
[WFQ] Weighted Fair Queuing packets are assigned in a specic queue.
Default Queue Weight [1-63] The default weight of the specied queue.
Default Queue Precedence [1-8] The Precedence of the specied group.
VC scheduling is unique from Default Queue’s.
PTM Interface
The SmartRG gateway’s VDSL2 standards support Packet Transfer Mode (PTM). An alternative to ATM mode, PTM transports
packets (IP, PPP, Ethernet, MPLS, and others) over DSL links. Reference the IEEE802.3ah standard for Ethernet in the First Mile
(EFM) for additional information.
After selecting Advanced Setup -> Layer2 Interface -> PTM Interface from the left navigation bar, click Add in the center pane. The
following screen will appear.
