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.

Home service networking (VLAN tag transparent transmission)

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.

Anyone knows how to configuring the Internet Access Service on Huawei OLT MA5800?

Huawei OLT MA5800 is connected to the remote ONT through a GPON port to provide users with highspeed Internet access services.

Prerequisites
The OLT is connected to the BRAS.
Related configurations are performed on the BRAS according to the authentication and
accounting requirements for dialup users. For details about the configuration, see the
configuration guide.
The ONT has been added to the OLT.
The VLAN of the LAN switch port connected to the OLT is consistent with the upstream
VLAN of the OLT.

Residential users generally access the Internet in Point-to-Point Protocol over Ethernet
(PPPoE) dial-up mode. PPPoE dial-up can be performed on personal computers (PCs) or
HGWs.

The configuration processes on HGWs of different models or in different appearances
are similar. This topic describes how to configure the Internet access service on an
HG239 that is connected to an ONT upstream through a LAN.

Procedure
l Configure Huawei OLT.
a. Configure a traffic profile.
Run the display traffic table ip command to query existing traffic profiles in the system. If the traffic profiles existing in the system do not meet the requirements, you need to run the traffic table ip command to add a traffic profile.
Set the profile ID to ftth_hsi, the CIR to 4 Mbit/s, and the priority to 0. In addition, configure the scheduling mode so that packets are scheduled according to their priorities.

huawei(config)#traffic table ip name ftth_hsi cir 4096 priority 0
priority-policy local-setting

b. Configure the mapping between a GEM port and a VLAN.
The service flow of user-side VLAN 45 is mapped to GEM port 14 in the ONT line profile.

huawei(config)#ont-lineprofile gpon profile-name ftth
huawei(config-gpon-lineprofile-1)#gem mapping 14 0 vlan 45
huawei(config-gpon-lineprofile-1)#commit
huawei(config-gpon-lineprofile-1)#quit

c. Configure the VLAN of the Ethernet port on the ONT HG8546M.
Add Ethernet port 1 to VLAN 45 in the ONT service profile.
huawei(config)#ont-srvprofile gpon profile-name ftth
huawei(config-gpon-srvprofile-1)#port vlan eth 1 45
huawei(config-gpon-srvprofile-1)#commit

d. Create an Internet access service VLAN and add an upstream port to it.
Add upstream port 0/9/0 to VLAN 100.
huawei(config)#vlan 100 smart
huawei(config)#vlan attrib 100 stacking
huawei(config)#port vlan 100 0/9 0

e. Create Internet access service flows.
Set S-VLAN ID to 100 and GEM port ID to 14. Use traffic profile ftth_hsi.
huawei(config)#service-port vlan 100 gpon 0/1/0 ont 1 gemport 14 multiservice
user-vlan 45 tag-transform translate-and-add
inner-vlan 1001 inbound traffic-table name ftth_hsi outbound traffictable
name ftth_hsi
huawei(config)#service-port vlan 100 gpon 0/1/0 ont 2 gemport 14 multiservice
user-vlan 45 tag-transform translate-and-add
inner-vlan 1002 inbound traffic-table name ftth_hsi outbound traffictable
name ftth_hsi

f. Save the data.
huawei(config)#save

ii. Set parameters for the Internet access service.
iii. Submit the configuration.

History of 10 GPON Technology Evolution

What Is 10G GPON?

• 10G GPON is evolved from the existing GPON technology, the factors promoting the technology evolution to Huawei 10G GPON are as follows:
• Developing services require higher bandwidths and the GPON technology cannot meet bandwidth requirements.
• Innovative access technologies on the user side require higher bandwidths and the GPON technology will face bandwidth bottlenecks.
•  A greater split ratio and a longer transmission distance increase network construction investments.

GPON Technology Evolution Roadmap

XG-PON, provides asymmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 2.488 Gbit/s ).
XGS-PON, provides symmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 9.953 Gbit/s ).
TWDM PON, provides symmetric 40G GPON transmission ( Maximum downstream line rate: 40 Gbit/s, Maximum upstream line rate: 40 Gbit/s ).

Standard Formulation Progress
In 2004, International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) Q2 started to research and analyze the possibility of evolving GPON to XG PON.
In September 2007, Q2 officially released the enhanced wavelength plan to standardize the coexistence of GPON and XG PON.

In November 2007, Q2 confirmed the XG PON standardization roadmap. With the goal of achieving low cost, high capacity, wide coverage, full service, and high communication capability, Q2 sped up the researching and finalizing of the XG PON standard.
In October 2009, Q2 officially released the phase 1 text for the XG PON standard during the SG15 plenary meeting. The text contained overall requirements for XG PON (G.987.1) and physical-layer physical media dependent (PMD) standard (G.987.2).
In June 2010, Q2 released the convergence-layer GPON transmission convergence (GTC) standard (G.987.3) and the management-layer optical network terminal management and control interface (OMCI) standard (G.988) for XG PON.

A 10G GPON network is of the point-to-multipoint (P2MP) type, which is the same as that of a GPON network.

10G GPON network contains an optical line terminal (OLT) Huawei MA800, optical network units

(ONUs), and an optical distribution network (ODN).

The Optical line terminal (OLT) is an aggregation device located at the central office

(CO) for terminating the PON protocol.

Optical network units (ONUs) are located on the user side, providing various types of

ports for connecting to user terminals.

The Optical distribution network (ODN) is composed of passive optical components

(POS) such as optical fibers, and one or more passive optical splitters. It interconnects

the OLT and ONUs.
