The GPON access supports high-bandwidth transmission, which effectively removes the bandwidth bottleneck in the access through twisted pairs and meets the users’ requirements on high-bandwidth services, such as high definition TV (HDTV) and live programs. In this topic, we take Huawei MA5680T and MA5821 ONU as examples to introduce how to configure the GPON access service in distributed mode.

Prerequisites

The corresponding VLAN must be already created in the system.

The upstream port of the VLAN must be already configured.

The MEF IP traffic profile must be already configured in the system.

In the distributed mode, you are required to configure the GPON MA5821 capability profiles and DBA profiles and download to the NEs so that they can be applied to the GPON access services.

The GPON MA5821 capability profile must be already configured in the system.

The DBA profile must be already configured in the system.

Context

The Gigabit-capable passive optical network (GPON) technology provides flexible access for broadband and narrowband services, and supports ultra-high bandwidth, multi-rate mode, and single optical fiber for providing users with voice, data, video, leased line, and distributed services over the IP network.

The GPON access service has various scenarios, which are mainly fiber to the home (FTTH), fiber to the building (FTTB), and fiber to the curb (FTTC). For different scenarios, the basic configuration procedures are the same except for some configuration data. Table 1 describes the differences of the configurations in different scenarios.

Table 1 Configuration description of the GPON access service in different scenarios

Application Scenario	General Networking	Description
FTTH	The ONU is installed at the user’s home to provide the user with multiple services through the Ethernet port and the telephone port.	· When configuring the triple play service, you need to configure different T-CONTs and GEM ports for the three types of services to separate the traffic. In addition, you need to configure different VLANs on the user side to distinguish the services. · When configuring the home Internet access service, if multiple PCs connected to the same ONU need to interconnect with each other, you need to configure the services of all the ports provided by the ONU with the same T-CONT and GEM port. In addition, the VLAN configuration of the ports must be the same. · If the ONU is connected to service terminals such as PC and STB that do not support the packets with a VLAN tag, you need to configure the native VLAN for the ONU port. Then, a VLAN tag is added to the packet when the packet reaches the ONU port and removed from the packet when the packet is transmitted from the ONU port.
FTTB	The ONU is installed in a building corridor and is connected to a layer-2 switch which provides multiple Ethernet ports for providing users with access services.	· When configuring the home Internet access service, if multiple users connected to the ONU need not interconnect with each other and each user needs to be authenticated individually, you need to configure the users on each ONU port with different T-CONTs, GEM ports, and VLANs. · When this scenario is applied in the small office and home office (SOHO) network, the ONU is connected to a layer-2 switch. In this case, you need to configure the services on each ONU port with different T-CONTs and GEM ports. · When the ONU is connected to a layer-2 switch, the packets that reach the ONU carry VLAN tags. In this case, you need not configure the native VLAN for the ONU port, but you need to make sure that the user-side VLANs are consistent with the VLAN tags of the packets.
FTTC	The ONU is installed in the cabinet at the curb and is connected to a Mini DSLAM or a Mini DSLAM with the GPON upstream function to provide users with access services.	You only need to configure the service port for theMA5680T or MA5683T according to the upstream VLAN of the Mini DSLAM. Since each service port may carry heavy traffic, it is recommended that you configure different T-CONTs and GEM ports for different service ports.

Figure 1 shows the flowchart for configuring the GPON access service.

1. Configuring the MA5821

This topic describes how to add MA5821 and configure the basic attribute parameters of the MA5821. To add MA5821 offline and configure the service of the MA5821 offline, perform this operation. After the MA5821 goes online, the configuration data is applied to the MA5821, and then the configuration of the MA5821 is completed.

2. Adding MA5821 Ports to a VLAN

This topic describes how to add MA5821 ports to a VLAN.

3. Configuring the GEM Port

This topic describes how to add the GEM port for transmitting traffic streams.

4. Adding a GEM Connection

This topic describes how to establish a connection between the ONU-side service and the GEM port, that is, to create a mapping between the GEM port and the upstream traffic stream of the MA5821 user port. The GEM port can be used for carrying services only after the corresponding GEM connection is established.

5.Configuring the Service Port

This topic describes how to configure the service port for the GPON access service

Context

T-CONT is short for transmission container. The T-CONT can be used for carrying services only after it is bound to the dynamic bandwidth allocation (DBA) profile.

After a T-CONT is bound to a DBA profile, the T-CONT uses the parameters defined in the DBA profile. The T-CONT can flexibly provide DBA solutions based on different configurations of the DBA profiles.

You can bind a T-CONT to a DBA profile only after adding MA5821.

By default, T-CONT 0 of MA5821 is used by OMCI and is bound to dba-profile_1.

Procedure

1. In the Main Topology, double-click the required MA5680T in the Physical Root navigation tree; or right-click the required MA5680T and choose NE Explorer from the shortcut menu.
