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

GPON Service Basic Concept
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.

GPON Service Basic Concept
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.

GPON Service Basic Concept
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.

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
HUAWEI TECHNOLOGIES CO., LTD. Page 14All rights reserved
Adding a T-CONT Profile
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.
HUAWEI TECHNOLOGIES CO., LTD. Page 15All rights reserved
Adding a T-CONT Profile
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
HUAWEI TECHNOLOGIES CO., LTD. Page 16All rights reserved
Adding an Alarm Profile
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.

Adding an Alarm Profile
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
− ......

Binding T-CONT Profiles
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.
HUAWEI TECHNOLOGIES CO., LTD. Page 19All rights reserved
Binding T-CONT Profiles
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
