Softswitch modes
There are two softswitch modes: H.248/Megaco and SIP softswitch modes. In these
modes, some configuration elements associated with VoIP provisioning can be
derived automatically from the DHCP/BRAS servers on the network. Package D
ONTs do not support softswitch modes.
The ONT and the softswitch trigger the ARP proxy function for individual MAC
address learning.

Edition 01 ONT Product Information Guide
Consideration
The static IP addresses must be derived and configured
along with termination identifiers on the ONT during the
POTS provisioning time. No DHCP function is expected.
The ONT IP addresses and the termination identifiers must
be configured on the voice gateway.
The ONT is expected to use an embedded configuration for
voice gateway applications. File download is not necessary.
The embedded configuration profile is stored on the ONT
flash. ONTs are shipped from the factory with the
embedded profiles already installed. New configuration
files can be downloaded to the ONT flash via FTP.
The ONT and voice gateway MAC addresses are fixed at the
ONT and the voice gateway. The MAC addresses are
exchanged as part of the ARP.
