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] Unspecified Bit Rate with no Peak Cell Rate, flow control or time synchronization
between the traffic 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 traffic predictable. Used
commonly in Video and Audio traffic network applications.
[NON
Realtime
VBR]
Non
Realtime
Variable
Bit
Rate
used
for
connections
that
trans-
port traffic 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 traffic.
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 specific queue.
Default Queue Weight [1-63] The default weight of the specified queue.
Default Queue Precedence [1-8] The Precedence of the specified 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.
