ONT Configuration
Introduction
This Chapter describes general principles of ONT configuration. It also defines configuration profiles.
ONT is configured with the help of a profile which defines high-level expression of data communication
channels. All operations related to channel creation are performed automatically. The way the data
communication channels are created depends on the selected service model (see Chapter 19, page 70).
ONT configuration includes assignment of configuration profiles and specification of ONT specific
parameters. Configuration profiles allow general parameters to be set for all or for a range of ONTs.
Profile parameters may include, for instance, DBA settings, configuration of VLAN operations in OLT and
ONT, settings of Ethernet ports in ONT. Specific ONT parameters allow each separate ONT to have its
own settings specified. Such settings include, for example, GPON password, subscriber's VLAN, etc.

General Configuration Principles
Service is the key term of ONT configuration. This term completely includes a channel through which
data is transferred from the interfaces located on the front panel of the terminal (see Chapter 15, page
54) to users' ports of ONT. There are two service profiles: cross-connect and dba. The cross-connect
profile creates a GEM service port, the dba profile allocates an Alloc-ID for this ONT and associates a
corresponding GEM port to the Alloc-ID.
