13.4.4 T-CONT Mode
Transmission containers (T-CONTs) are used for the management of upstream bandwidth
in PON section of the TC layer. T-CONTs dynamically receive grants, identified by Alloc-
ID, from the OLT. A single T-CONT can carry GEM traffic with various service classes. It
also accommodates one or more physical queues and aggregates them into a single logi-
cal buffer so that this feature can be used for enhanced QoS implementation in upstream
direction. The mechanism of T-CONT is shown in Fig. 12.5.

The V8102 provides the easy and efficient management solution using T-CONT concept
with the Traffic profile.
A GPON port is connected with multiple ONUs/ONTs via splitter. The GPON encapsula-
tion mode (GEM) frames are transmitted between the OLT and the ONUs (ONTs). A GEM
frame is identified by a GEM port ID. In the upstream direction, the T-CONTs carry the da-
ta stream.
The Traffic profile is a collection of configurations about dynamic bandwidth allocation and
GEM port according to the service priority levels. You can configure each T-CONT to
have a priority value using GEM port number.
You need to open Traffic Profile Configuration mode to configure a T-CONT. A T-CONT ID
can include multiple T-CONTs and supports up to 8 priority queues per T-CONT.
To create a T-CONT ID in Traffic Profile Configuration mode, use the following command.
Creates a T-CONT ID.
TCONT-ID: T-CONT ID, 1 to 32
After opening T-CONT Configuration mode, the prompt changes from SWITCH(config-
traffic-pf[NAME])# to SWITCH(config-traffic-pf[NAME]-tcont[TCONT-ID])#.
