hi,

Generally speaking, ONT is a optical network terminal for the user side.
The difference between ONT and MDU is that ONT is a optical network terminal, directly located on the client side, and there may be other networks between users, such as Ethernet. MDU can be connected to a gateway device xDSL (ADSL,VDSL) or an Ethernet access port before being connected to a network terminal

the simple bridge model ONT no IP configure and cannot Telnet , other ONT and MDU can configure IP and Telnet
