1 Overview
1.1 System Overview The SmartAX OT928G is a single business unit (SBU) for commercial users. It provides Gigabit-capable Passive Optical Network (GPON) access with the upstream rate 1.244 Gbit/s and downstream rate 2.488 Gbit/s to satisfy the requirements on voice, data and video services over a single optical fiber. The OT928G resides in the GPON user access layer, connecting to the Synchronous Digital Hierarchy (SDH), Digital Data Network (DDN) and Internet Protocol (IP) network through the optical uplink port. Moreover, The OT928G supports embedded VoIP Codec through GPON access to provide VoIP service. The NSP/ISP can provide the VoIP service without deploying the IAD on the CPE side. The OT928G meets the networking requirements on Time Division Multiplexing (TDM) dedicated line access, Ethernet dedicated line access, base station transmission, and Fiber To The Building (FTTB). The OT928G supports optical network termination management and control interface (OMCI), which helps the service provider to provision services remotely and network maintenance engineer to maintain and manage the device remotely.

Context Before logging onto the device, make the following preparations: z
Use a network cable to connect the OT928G to a PC.
z
Power on the OT928G and the PC.
z
Configure the IP address of the PC and that of the OT928G in the same network segment. The default IP address of the OT928G is 192.168.1.1, with the subnet mask 255.255.255.0. You can configure the IP address of the PC as 192.168.1.2.
After logging onto the device, you will have to enter the user name and password again if the PC is idle for over 10 minutes.
Procedure Step 1 Enter the IP address of the OT928G in the address bar of the browser. Step 2 In the displayed dialog box, enter the user name and password. Both of them are "admin" by default. Step 3 Click OK. Step 4 After the authentication, the browser displays the home page of the OT928G. ----End
If you have any problems during the configuration, contact your carrier for help.
3.3 Configuring the QinQ VLAN This section describes how to configure the QinQ function working mode and apply to a port.
Context Virtual local area network (VLAN) is originally a virtual workgroup concept. It realizes the isolation between different workgroups in one switch and these workgroup share one switch. All users in VLAN can communicate with each other, but the number of VLANs is limited to 4096. For a single access switch, 4096 VLANs are completely enough. But for a large layer-2 network, 4096 VLANs are obviously not enough. The QinQ is proposed to dissolve the VLAN limitation. The QinQ technology is also called the Stacked VLAN or Doubled VLAN. This technology complies with the IEEE 802.1ad standard. It encapsulates the user private network VLAN Tag in the public network VLAN Tag to make messages traverse the backbone network (public network) of carriers with two layers of VLAN Tags. In public networks, messages are transmitted only according to the external VLAN Tag (namely the public network VLAN Tag) and the private network VLAN Tag is shielded.

Technically, the QinQ completely supports multi-layer stacking without limitation. It is only restricted by the length of the Ethernet message. So, the QinQ features excellent expandability. QinQ has many different names in the industry, including Tag in Tag, VLAN VPN, StackVLAN and SVLAN. The QinQ technology can mainly solve the following problems: z
Easing the increasing deficiency of public network VLAN ID resources
z
User can plan their own private VLAN IDs and will not conflict with public network VLAN IDs
z
Providing small-sized metropolitan area networks (MANs) or enterprise networks with a relatively simple layer 2 VPN solution

Parameter QinQ Status
Parameter Description QinQ VLAN status. Control the QinQ VLAN function on the user side z
On: When the port receives an Ethernet frame, no matter whether the Ethernet frame contains the VLAN Tag or not, the OT928G will label the Ethernet frame with the VLAN Tag of the port default VLAN. (If the frame is received tagged, the 802.1p priority of the original tag will be used in outer VLAN tag instead of using the port default priority.(see Table 4-8 Processing of the received upstream Ethernet frame in various QinQ statuses) In this way, if the received message has already contained a VLAN Tag, the Ethernet frame will become a double-tagged Ethernet frame. If the received Ethernet frame is untagged, it will become a single-tagged Ethernet frame with the default VLAN Tag of the port.
z
Off: When the port receives an Ethernet frame, the OT928G will only add the port default VLAN to the untagged Ethernet frame or replace the VLAN id of priority-tagged frames with default VLAN id. In other words, the OT928G will never add a VLAN Tag to the received tagged Ethernet frame. Default value : Off
3.4 Configuring the Forced Priority Setting This section describes how to configure the forced priority for a GE or FE port.
Context When the GE or FE port is used, you must configure the parameters on the Web page depending on whether you trust the device connected to the GE or FE port or not. In the case that the connected device is not trustable, you should turn on the corresponding Forced Priority Status. Otherwise, you can turn off the corresponding Forced Priority Status.
