The individual fields on this screen are defined as follows:
Field Name
Description
VPI
[0-255] Enter a Virtual Path Identifier. VPI is an 8bit identifier to uniquely identify a network path for
ATM cell packets to reach its destination. Every ATM path requires a unique VPI number to associate.
Works together with the VCI. Each individual DSL circuit cannot have the same VPI/VCI combination.
VCI
[32-65535] Enter a Virtual Channel Identifier. VCI is a 16bit identifier that has a unique channel.
Select DSL Latency
[Path0 Fast] No error correction and can provide lower latency on error free lines.
[Path1 Interleaved] Error checking that provides error free data which increases latency.
[Path0&1 Both] Fast & Interleaved

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.
When your desired settings have been entered, click the
Apply/Save
button to commit your changes.

The individual fields on this screen are defined as follows:
Field Name
Description
Select DSL Latency
[Path0 Fast] No error correction and can provide lower latency on error free lines.
[Path1 Interleaved] Error checking that provides error free data. This tends to increases
latency.
[Path0&1 Both] Fast & Interleaved.
Weighted Round Robin
Time slices are assigned to each process in equal portions and in circular order, handling
all processes without priority (also known as cyclic executive).
Weighted Fair Queuing
A data packet scheduling technique allowing different scheduling priorities to statistically
multiplexed data flows. Since each data flow has its own queue, an ill-behaved flow (who
has sent larger packets or more packets per second than the others since it became ac-
tive) will only punish itself and not other sessions.
Default Queue Weight
[1-63] Enter a default weight of the specified queue.
Default Queue Precedence
[1-8] Enter a precedence for the the specified queue.
Default Queue Minimum Rate
[1-0 Kbps] The default minimum rate at which traffic can pass through the queue.
[-1 Indicates no shaping.]
Default Queue Shaping Rate
[1-0 Kbps] The shaping rate for the specified queue.
[-1 Indicates no shaping.]
Default Queue Shaping Burst Rate
[>= 1600] The maximum rate at which traffic can pass through the queue.

ETH Interface
Your gateway has four LAN ports. One of them can be re-purposed to become a WAN port when such an RJ45 WAN port is desired.
After selecting
Advanced Setup -> Layer2 Interface -> ETH Interface
from the left navigation bar, click
Add
in the center pane. The
following screen will appear. From the drop-down menu in the center pane, simply select the LAN port you wish to act as a WAN
port.
WAN Service
There are several variations of WAN Service available to configure. The three core variations are:
PPP over Ethernet (PPPoE)
IP over Ethernet
Bridging
This chapter will illustrate a sample configuration scenario down each of these three variations and define the available fields to
customize your WAN service setup.
PPP over Ethernet
After selecting
Advanced Setup -> WAN Service
from the left navigation bar, click the
Add
button. A progression of several screens
will follow.
Advance to the next after completing the required fields using the
Next
button appearing near the bottom of each
screen.

First, select the Layer2 interface to use for the WAN service.
Click the
Next
button to advance to the next step.
Next, select the type of WAN service you wish to create.
For this example choose
PPP over Ethernet.
Click
Next
after completing the necessary fields.
The individual fields on this screen are defined as follows:
Next, configure the PPP Username, Password and related information.

[PPP over Ethernet PPPOE, IP over Ethernet IPoE, Bridging]
Enter Service Description
Enter a name to describe this configuration.
Network Protocol Selection
A data packet scheduling technique allowing different scheduling priorities to statistically mul-
tiplexed data flows. Since each data flow has its own queue, an ill-behaved flow (who has sent
larger packets or more packets per second than the others since it became active) will only
punish itself and not other sessions.
