ONT receives information about the configuration from an XML file
Path to configuration file and FTP credentials can be forwarded with few methods
DHCP Server (using option 66 and 67)
OMCI by firmware upgrade
OMCI OLT provisioning service (for example on OLT vendors from Dasan/Zyxel/Huawei)
ONT uses the IP-host interface (Management) for Provisioning, XML files are downloaded only through this interface. Iphost is OMCI controlled interface supported by multiple OLT vendor as like Huawei, DASAN, ZTE, Nokia, Zyxel, etc which is used only to manage ONT and it’s isolated from another services
What You need
FTP Server – put here XML files with configuration for ONT[necessary]
If You use Universal DHCP provisioning – DHCP Server which supports DHCP option 66 and/or option 67
If You use provisioning via OMCI (vendor specific) or firmware upgrade method, you need to prepare additional configuration on OLT side
How it works
Connect new ONT to OLT
ONT receive information from DHCP option 66/67 or Vendor Provisioning system about XML file location and path
ONT try to download XML file
ONT validate XML file structure
ONT apply new settings and if it’s needed ONT restarts
Advantages of XML provisioning
Easy and fast configuration for new CPE in your network
CPE will receive configuration even after it was restored to factory defaults settings
Provisioning through DHCP option66/67 is independent of vendor (one configuration for all OLT vendors)
It works at GPON and ETHERNET networks at the same time
Easy to manage, if You want to change the configuration for some customers You need only change it in the XML file
Easy to integrate with NMS (Network Management System)
ONT acts the same way, no matter which method of provisioning has been performed. Below, you can find a block scheme that can help you to understand behaviour of the device.
