The Specific profile will be created on ONT in the last step at the bottom
of the flowchart, Activate the zNID and add support to the zNID.
Once the OMCI profiles are created, if you have similar scenario in other
MXKs, you can share the OMCI profile between MXKs by using the
gpononu profiles export me|gen|spec and gpononu profiles import
me|gen|spec commands.
• Create bridge additions
Bridge additions include GPON traffic profile (GTP) and packet rule. A
GPON traffic profile is added in the bridge add command for ONT GEM
port; packet rules are also added in the bridge add command, such as
DHCP insert, rate limiting, destination MAC address swapping.
In this example, we will only describe how to create GPON traffic profile.
GPON traffic profile could be used to prioritize traffic in service-based
order. You can specify guaranteed upstream bandwidth and traffic class
for different services in the GTP:
– For high speed data service, you might consider specifying a higher
upstream bandwidth than you would for voice and video. The
minimum bandwidth 512 kbps is recommended for voice and video
services.
– Voice and video services need a constant and guaranteed cell rate
during the lifetime of the connection, so traffic class CBR would be
appropriate for those GEM ports running voice and video services.
UBR would be appropriate for delay-tolerant or non-real-time
application, such as data service.
• Configure bridge
The bridge type we build depends on the service (data, video, or voice).
For the data and video services we will use asymmetric bridges (uplink,
downlink bridges).
For the voice service we will use a TLS bridge. No matter which VoIP
protocol, TLS bridges are better suited for downstream initiated calls,
because in the worst case scenario you will always be able to get the
MAC address of the VoIP supplying access device (in this case the zNID).
If there is no activity on the VoIP bridge, then the MAC address of the
VoIP supplying access device will eventually timeout the MAC address of
the VoIP in the bridge forwarding table. Unlike the downlink of an
asymmetric bridge, the TLS bridge will flood all the bridge interfaces of
the TLS VoIP VLAN and rediscover the VoIP supplying access device.
• Activate the zNID and add support to the zNID.
Make sure to provision the logical connections for data, video, and voice
services in the MXK and ONTs before activating the ONTs in order to
avoid having to re-sync or reboot the ONUs eventually.
In this step we will create Specific profile on the zNID, and then activate
the zNID.
