LP MDU outdoor ONT
The LP MDU outdoor ONT terminates services at the subscriber’s premises and is
suitable for multi dwelling unit (MDU) applications. The LP MDU outdoor ONT
must be installed in a cabinet, closet, CO, outdoor enclosure, or other
environmentally-protected area. The LP MDU ONT can also be configured in a
small Alcatel-Lucent enclosure for outdoor or indoor deployment. There are two
types of LP MDU outdoor ONT: the VDSL LP MDU ONT (O-24121V-A and
O-24120V-A) and the GE LP MDU ONT (O-24121G-A and O-24120G-A).
