Multiple services in multiple VLANs Service Networking (GPON/10G GPON)

In home service (VLAN tag transparent transmission) networking, a distributed converged
cable access platform (D-CCAP) connects to cable modems (CMs) at user homes through
radio frequency (RF) ports and provides home services for users, including the cable TV
(CATV) service, Internet access service, and VoD service. This section describes how to
configure the optical line terminal (OLT MA5600T)  to provision the home services.

Service Requirements
Users require the provisioning of the broadcast and TV services, Internet access service, and
VoD service. Broadcast and TV services can be provisioned immediately after the distributed
converged cable access platform (D-CCAP) hardware is connected. This section only
describes how to configure the Internet access service, and VoD service.

Usage Scenario
Some carriers deploy HGWs on the lower-layer of CMs. The HGWs add different VLAN tags
to packets based on service types. This requires that the CMCs support transparent
transmission of VLAN tags. As shown in Figure 9-17, a D-CCAP is deployed on an optical
node and cable modems (CMs) are deployed at user homes. The CMs connect to radio
frequency (RF) ports on the MA5633 through cables.
-Port 1 on CM connects to a PC to provide the Internet access service. A set top box
(STB) connects to the distributor to provide a backhaul channel for the VoD service.
-Users access the Internet through Dynamic Host Configuration Protocol (DHCP) dialup.
-The IP addresses of the CM, STB, and PC are assigned by the DHCP server and in
different network segments.
-The D-CCAP is used as a GPON remote extended frame. This reduces D-CCAP
management and maintenance costs and simplifies configurations.

Configuration Process

Configuration roadmap for the home service networking

1, Add a remote extended frame to the OLT.

An MA5633 that works as a remote extended frame connects to a port on a cascading board of an Huawei optical line terminal (OLT). You can configure the remote extended frame only after adding it to the

OLT.

2, Configure radio frequency (RF) port parameters (DOCSIS 3.0). Configure radio frequency (RF)

port parameters (DOCSIS 3.1). Radio frequency (RF) port parameters define the frequency spectrum range for signal transmission and modulation mode.

The configuration of RF port parameters implements data service transmission over

cables. RF port parameters can be configured using either of the following methods:

-Use a cable initialization profile to configure the parameters.

-Customize the parameters in cable mode.

3, Configure the high-speed Internet (HSI) service.

4, Configure the DOCSIS VoD service.

If Huawei ONU MA5633 is not equipped with a built-in EQAM module, the MA5633 uses DOCSIS channels to transmit VoD data.

If the MA5633 is equipped with a builtin EQAM module, the MA5633 sets idle downstream DOCSIS channels as EQAM channels to transmit VoD data.

The DOCSIS VoD service and the EQAM VoD service are generally not concurrently used. 

5, Verify the configured services.

An OLT supports multiple remote service verification methods. This allows commissioning and configuration engineers to remotely verify services.

1. A DHCP dialup emulation test checks whether the OLT can communicate with the DHCP server and verifies CM DHCP configurations on the DHCP relay, proxy, and server.

2. The status of a CM can be queried. Based on the information, you can determine whether the CM is online.
