ESCRIPTION
This Quick Start provides instructions for the installation of the
GPON 452/454 Optical Network Termination (ONT) units (see part
numbers listed below). The ONTs have POTS and GigE interfaces
that provide triple-play services. The GPON 452 ONT has two
POTS ports and two Gigabit-Ethernet ports; the GPON 454 ONT
has four POTS ports and four Gigabit-Ethernet ports.
The ONT is to be enclosed in a weather-hardened Network Inter-

figure below illustrates the ONT in the context of the NID with the
access door of the NID removed.
