WPS Button
The WPS button is located on the top of the unit. It triggers WPS (Wi-Fi Protected Setup™) mode. WPS is a standard means for creating a secure connection between your gateway and various wireless client devices. It is designed to simplify the pairing process
between devices.
If you have client devices that support WPS, use this button to automatically configure wireless security for your network. For specific instructions, refer to the Quick Start Guide included with your gateway. Also see the Wireless section of this manual.
WiFi Button
The WiFi button is located on the top of the unit and toggles the WiFi radio on and off.
To activate the WiFi radio, press and hold the WiFi button for 3-5 seconds and then release. Repeat this step to deactivate the WiFi
radio.
1. Plug the power adapter into the wall outlet and then connect the other end to the Power port of the gateway.
2. Connect the LAN port of the gateway to the network card of the PC using an Ethernet cable.
3. Turn on the unit by pressing the On/Off button on the side of the gateway.
Note: If you use 3G WAN service, connect the 3G USB data card to a USB port of the gateway. If you use the Ethernet uplink, connect
to the WAN interface using an Ethernet cable. You cannot use the xDSL uplink, 3G WAN service, and Ethernet uplink all at the same
time.
Your gateway is now automatically being set up to connect to the Internet. This process may take a few minutes to complete before
you can begin using your Internet applications (browser, email, etc.).
If you are unable to connect to the Internet, confirm that all cable connections are in place and the router’s power is turned on.
To manually configure the SmartRG SR555acSR655ac gateway, access the gateway's embedded UI.
1. Open a Web browser on your computer.
2. Enter http://192.168.1.1 (the default IP address of the DSL gateway) in the address bar. The login page appears where you
can access the gateway's GUI or view the system log. For more information about configuring system logs, see the System Log
topic in this User Manual.
3. Click the Manage gateway (advanced) link at the top right of the page.
4. Enter the admin user name and password. The default admin username/password are admin/admin. The default username/password of the common user are user/user. It is recommended that you change these default values after logging in
to the DSL gateway for the first time.
5. Click OK. The gateway interface appears, showing the Device Info summary page.

default. If your network is highly customized, you may need to modify some of the settings, such as Username and Password.
ATM Interface
On this page, you can configure Asynchronous Transfer Mode / Permanent Virtual Conduit (ATM/PVC) settings for your gateway. You
can customize latency options, link type, encapsulation mode, and more.
Note: Devices (routers) on both ends of the connection must support ATM / PVC.
1. In the left navigation bar, click Advanced Setup > Layer2 Interface > ATM Interface and then click Add. The following page
appears.
2. Modify the settings as desired, using the information provided in the table below.
3. Click Apply/Save to commit your changes.
The fields on this page are explained in the following table.
Field NameDescription
VPIEnter a Virtual Path Identifier. A VPI is an 8-bit identifier that uniquely identifies a network path
for ATM cell packets to reach its destination. A unique VPI number is required for each ATM
path. This setting works with the VCI. Each individual DSL circuit must have a unique VPI/VCI
combination. String limits are: 0-255.
VCIEnter a Virtual Channel Identifier. A VCI is a 16-bit identifier that has a unique channel. Options
are: 32-65535.
Select DSLSelect the level of DSL latency. Options are:
l Path0 Fast: No error correction and can provide lower latency on error free lines.
l Path1 Interleaved: Error checking that provides error free data which increases latency.
l Path0 and Path1: If you are not certain which method is best, you can select both.
Select Link Type Select the linking protocol. EoA is the most popular with PPPoA a close second (used with many
legacy ISPs). Options are:
l EoA: Ethernet over ATM.
l PPPoA: Point-to-Point Protocol over ATM.
l IPoA: Internet Protocol over ATM.
Encapsulation
Mode
Select whether multiple protocols or only one protocol is carried per PVC (Permanent Virtual
Circuit). Options are:
l LLC/ENCAPSULATION: (Available for PPOA only) Logical Link Control (LLC) encapsulation
protocols used with multiple PVCs
l LLC/SNAP-BRIDGING: LLC used to carry multiple protocols in a single PVC.
l LLC/SNAP-ROUTING: (Available for IPoA only) LLC used to carry one protocol per PVC.
l VC/MUX: Virtual Circuit Multiplexer creates a virtual connection used to carry one pro-
tocol per PVC.
Service Category Select the bit rate protocol. Options are:
l UBR without PCR: Unspecified Bit Rate with no Peak Cell Rate, flow control or time syn-
chronization between the traffic source and destination. Commonly used with applications that can tolerate data / packet loss.
l UBR with PCR: Same as above but with a Peak Cell Rate.
l CBR: Constant Bit Rate relies on timing synchronization to make the network traffic pre-
dictable. Used commonly in Video and Audio traffic network applications.
l Non Realtime VBR: Non Realtime Variable Bit Rate used for connections that transport
traffic at a Variable Rate. This category requires a guaranteed bandwidth and latency. It
does not rely on timing synchronization between the destination and source.
l Realtime VBR: Realtime Variable Bit Rate. Same as the above option but relies on timing
and synchronization between the destination and source. This category is commonly
used in networks with compressed video traffic.
Scheduler for
Queues of Equal
Precedence as
the Default
Queue
Minimum allowable rate (cells per second) at which cells can be sent on a ATM network. The
default is -1 (no shaping).
The algorithm used to schedule the queue behavior. VC scheduling is different than the default
queues. Options are:
l Weighted Round Robin: Packets are accessed in a round robin style. Classes can be
assigned.
l Weighted Fair Queuing: Packets are assigned to a specific queue.
l Default Queue Weight: The default weight of the specified queue. Options are 1-63.
l Default Queue Precedence: The precedence of the specified group. Options are 1-8.
l VC WRR Weight: The weight of the specified virtual channel queue. Options are 1-63.
l VC Precedence: The priority of the specified virtual channel queue. Options are 1-8.
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. For more information, refer to the IEEE802.3ah standard for Ethernet in the First
Mile (EFM). Some 500 series gateways have a PTM interface configured by default.
On this page, you can configure a PTM interface for your gateway.
1. In the left navigation bar, click Advanced Setup > Layer2 Interface > PTM Interface and then click Add. The following page
appears.
The fields on this page are explained in the following table.
Field NameDescription
Weighted Round RobinTime slices are assigned to each process in equal portions and in circular order, hand-
ling all processes without priority (also known as cyclic executive).
Weighted Fair QueuingA data packet scheduling technique allowing different scheduling priorities to be
assigned to statistically multiplexed data flows. Since each data flow has its own
queue, an ill-behaved flow (that sent larger packets or more packets per second than
the others since it became active) will only affect itself and not other sessions.
