5 Configuration
Configuration of the Fiber Gateway equipment is done remotely, using OMCI and TR-069.
5.1 Fiber Gateway Activation
The equipment activation process has a distributed set of procedures that allow the connection of an
inactive equipment to a PON network. This configuration is done following the procedure described in
the OMCI protocol.
5.2 Costumization
For customization process, the requirements specified in the G.8907.1 are taken into account.
5.2.1 Software download from the OLT
The software download is made following the OMCI-based procedure.
The Managed Entity (ME) in charge of managing the software download is named Software Image. Per
each ME containing independently-manageable software, the Fiber Gateway creates two software
images. Each image will have three attributes:
• Valid - if it has been verified that it’s content is an image with executable code;
• Committed - if once the Fiber Gateway is rebooted, it is loaded and executed;
• Active - if it is loaded and it is being executed in the Fiber Gateway.
There can be only one active image and only one committed image at a given moment. The Fiber
Gateway goes through a series of states in order to download and activate a software image. Each state
is defined according to the states of the variables of both images. The OLT controls the Fiber Gateway
state through a series of commands:
• Start download
o It starts the software download sequence. This action is only valid for inactive
and non-committed software images;
• Download section
o It downloads a section of a software image. This action is only valid for an image
that is being downloaded;
• End download
o It indicates the end of a download sequence, providing the CRC and
information about version for the final verification of the downloaded software
image. This action is only valid for a software image that is being downloaded;
• Activate image
o It loads/executes a valid software image. When this action is applied to an
inactive software image, the execution of the current code image is suspended,
the associated software image is loaded from the non-volatile memory and the
execution of the new code image is started. When this action is applied over a
software image that is active, a reboot is executed;
• Commit image
o It selects a valid SW image to be loaded and executed by default when the
Fiber Gateway is restarted;
• Composition of the Software Image
