PRE ONT 
pre-configuration file
The XML-based PRECONFIG file controls the working 
mechanics of the ONT for various services. The 
default behavior of different ONTs may vary based on 
the factory settings. 
The pre-configuration file includes the factory default 
value for the residential gateway.
Note: the pre-configuration file does not work with SFU 
ONTs; therefore, this feature applies only to 
Residential Gateway ONTs.
The pre-configuration file can be used as is, but Nokia 
provides its customers with the flexibility to customize 
the pre-configuration file.
This pre-configuration file enables operators to change 
the default behavior by downloading a customized 
pre-configuration based on customer inputs.
This PRE XML file includes a custom OPERID.
The Nokia defined index for the PRECONFIG file is: 
"PRE"
HGU ONTs:
G-240G-C,G-240W-A, 
G-240W-B, G-240W-C, 
G-240W-G, I-240W-A
CFG ONT configuration 
delta file
The XML-based CFG file updates the configurable 
parameters (the PRE settings) in the existing PRE file 
of a deployed ONT, where required.
This configuration file enables operators to change the 
deployed behavior by downloading customized 
updates in the CFG file.
This file is used only to modify the parameters in the 
PRE file; it is not used for service provisioning.
No OPERID is required, because the update is based 
on the OPERID used for the PRE file.
The Nokia defined index for the PRECONFIG DELTA 
file is: "CFG"
XML Voice XML file The Voice XML file provides an alternate method for 
securely downloading voice parameters from the OLT, 
rather than using FTP (OMCIv1/OMCIv2) or HTTPS 
(TR-069). Downloading this file makes the applicable 
changes in the voice parameters.
This file enables operators to change the voice 
behavior by downloading the updated voice XML file.
Nokia recommends using this procedure, rather than 
embedded voice XML files.
The Nokia defined index for the Voice XML file is: 
"XML"
