GPON Service Multiplex Structure

Each ONU/ONT can be allocated multiple T-CONT

Upstream bandwidth allocation based on T-CONT,which is decided by COS requirement ,

can be divided into 5 types.

GEM port is service control channel ,can get one service flow or multiple service flow into one GEM port channel , just like ATM pvc

Flow classification can based on VLAN ,802.1p ,also L3/L4 indentifier.

GPON Service Basic Concept

T-CONT

In the upstream direction, the T-container (T-CONT) is used

to bear the service traffic. GPON uses the T-CONT to

implement the service convergence. T-CONT is the basic

control unit of the upstream service traffic in the GPON

system.

Alloc-ID

Each T-CONT type is identified by the Alloc-ID uniquely.

The Alloc-ID ranges from 0 to 4095. It is allocated by the

OLT, that is, a T-CONT can only be used by one ONU/ONT

of the PON IF.



T-CONT Bandwidth Types

Each T-CONT corresponds to the service traffic of one

bandwidth type. Each bandwidth type has its own QoS

feature. DelaySensitive

GEM Port

GPON Encapsulation Method (GEM) frames are

transmitted between the OLT and the ONU/ONT. Each T-

CONT consists of one or more GEM ports. Each GEM port

bears one kind of service traffic.

GEM Port-ID

Each GEM port is identified by the Port-ID uniquely. The

Port-ID ranges from 0 to 4095. It is allocated by t he OLT,

that is, a GEM port can only be used by one ONU/ONT of

the PON IF.



Relationship Between T-CONT, GEM Port and Service Traffic

The management channel shall be configured with a GEM

port and a T-CONT separately to ensure the bandwidth for

the terminal management service.

The GEM port is the virtual connection used to identify the

service traffic.



Relationship Between T-CONT, GEM Port and Service Traffic

Mapping Details Application

VLAN ID mapping

It maps the service traffic of the specified VLAN ID to a unique Port-ID. In QinQ mode, one GEM port supports multiple VLAN ID mappings.

The ONU/ONT adopts the VLAN ID to differentiate the user service traffic.

802.1p mapping

It maps the specified 802.1p service traffic to a unique Port-ID. In QinQ mode, one GEM port supports multiple 802.1p mappings.

The ONU/ONT adopts the priority to differentiate the user service traffic. The user packet must be Pri-tagged, that is, the VLAN ID is 0.

VLAN ID+802.1p mapping

It maps the specified VLAN ID + 802.1p service traffic to a unique Port-ID. In QinQ mode, one GEM port supports multiple VLAN ID + 802.1p mappings.

The ONU/ONT adopts the priority and VLAN ID to differentiate the user service traffic.

Other operations


Adding a CAR Profile

Specification

By default, the system has seven CAR profiles with indexes

from 0 to 6,the system will adjust the CAR value you input

to a multiple of 64.

Example

Add a CAR profile with CAR of 4096 kbit/s

− huawei(config)#traffic table ip car 4096 priority 3 priority-policy

pvc-Setting



Specification

The MA5680T supports up to 512 T-CONT profiles.T-CONT

profiles 1–9 are the default profiles

The system adjusts the bandwidth value you input when

you add a T-CONT profile to a multiple of 64.



Command

− tcont-profile add [ profile-id profile-id ] [ profile-name profile-

name ] { type1 fix fix-value | type2 assure assure-value | type3

assure assure-value max max-value | type4 max max-value |

type5 fix fix-value assure assure-value max max-value }

Example

Add a T-CONT profile with index of 30 and fixed bandwidth

of 100 Mbit/s

− huawei(config)#tcont-profile add profile-id 30 type1 fix 102400



Specification

The ONT line alarm profile consists of a series of alarm

threshold parameters. It is used to monitor the performance

of the ONT line. When a statistic reaches the related alarm

threshold, the host is notified of this information, and an

alarm is sent to the log host and the NMS.

The system supports up to 50 alarm profiles.

There is default alarm profile (profile 1) in the system. It

cannot be deleted but can be modified.



Example

− huawei(config)#gpon alarm-profile add profile-id 2

− { <cr>|profile-name<K> }:

− Command:

− gpon alarm-profile add profile-id 2

− > GEM port loss of packets threshold (0~100)[0]: 20

− .......

− > Ethernet FCS errors threshold (0~100)[0]: 50

− ......



Specification

This operation helps you to bind a T-CONT profile with a T-

CONT or batch binding .

You can bind a T-CONT profile with a T-CONT or batch

binding only after the ONTs are added.



Example

Bind T-CONT profile 12 with T-CONT 7 on ONT 0 which is

under port 0/3/0

− huawei(config-if-gpon-0/3)#tcont bind-profile

− { portid<U><0,1> }:0

− { ontid<U><0,63> }:0

− { tcont-list<S><1,13> }:7

− { profile-id<K>|profile-name<K> }:profile-id

− { profile-id<U><1,512> }:12


Adding a GEM Port

Specifications

One ONT supports eight T-CONTs and 32 GEM Ports.One GPON IF supports up to 4096 GEM Ports.

If the upstream and downstream CAR profiles for a GEM Port are different, make sure that the priorities configured for the upstream and downstream CAR profiles are the same.

Example

− huawei(config-if-gpon-0/12)#gemport add 1 10 1 gemport-id 140 up-car 5 down-car 6 encrypt on

▪ Add GEM Port 140 to T-CONT 1 on ONT 10 under port 0/12/1, with upstream CAR profile 5, downstream CAR profile 6 and downstream encryption switch on


Adding and activating an ONT

Add ONT

− huawei(config-if-gpon-0/12)#ont add 0 2 hwhw-66666666

password-auth MA5680T type ot923g mapping-mode 8021p

▪ Add ONT 2 to port 0/12/0 and assume that:

▪ The SN of ONT 2 is hwhw-66666666

▪ The model of ONT 2 is OT923-G.

▪ The authentication mode is password-auth.

▪ The password is MA5680T.

▪ The mapping mode is 802.1p.

Activate ONT

− huawei(config-if-gpon-0/2)#ont activate 1 0

▪ Activate ONT 0 under port 0/2/1


Other Operations

Configuring the CATV Function of an ONT

− huawei(config-if-gpon-0/12)#ont catv 1 0 off

Enabling the ONT Auto-find Function under a GPON Port

− huawei(config-if-gpon-0/12)#port 1 ont-auto-find enable

▪ Enable the ONT auto-find function under GPON port 0/12/1

Setting the Timeout Time for ONT Auto-find

− huawei(config)#ont autofind timeout 150

▪ Set the timeout time for ONT auto-find as 150 seconds


Other Operations

Confirming an Automatically Found ONT

− huawei(config-if-gpon-0/12)#ont confirm 1 all password-auth

MA5680T type ot923g

▪ To confirm all the automatically found ONTs under port 0/12/1, with

password of MA5680T and model of OT923-G

Setting the Minimum and Maximum Logical Reach

− huawei(config-if-gpon-0/12)#port 1 range min-distance 10 max-

distance 15

▪ Set the minimum and maximum logical reach of the ONT under

port 0/12/1 to 10 km and 15 km respectively
