POTS ports and two Gigabit Ethernet ports; the GPON TA374 2nd Gen
ONT has four POTS ports and four Gigabit Ethernet ports.
The ONTs are enclosed in a weather-hardened Network Interface Device
(NID) which mounts to the exterior of a building. The figure below
illustrates the TA374 ONT in the context of the NID with the access door of
the NID removed.
