2 Introduction
GPON network belongs to one of the varieties of passive optical PON networks. This is one of the most
modern and effective solutions for "last mile", which allows significant savings on cable infrastructure and
provides data transmission speed of up to 2.5 Gbps downlink and 1.25 Gbps uplink. The use of GPON-based
solutions in access networks makes it possible to provide end users with new IP services together with
traditional ones.
The main advantage of GPON is the use of a single line terminal (OLT) for multiple subscriber devices (ONT).
OLT is a converter of Gigabit Ethernet and GPON interfaces, which serves to connect the PON network with
higher-level data transmission networks. The ONT device is designed to connect customers' equipment to
broadband access services. It can be used in residential areas and business centers.
The user manual describes the purpose, main technical specifications, configuration rules and monitoring of
the optical network terminal NTU-MD500P.
Notes and Warnings
The tips contain important information or recommendations for using and configuring the device.

The notes contain additional information on using and configuring the device.

Warnings inform of the situations when actions may harm the device or a user, lead to fault operation
of the device or data loss.

3 Product Description
3.1 Purpose
NTU-MD500P is an optical network terminal that has four 10/100/1000BASE-T ports with support for IEEE
802.3at PoE+ technology. NTU-MD500P provides up to 30 W of power on 10/100/1000BASE-T ports with a
PoE power budget of 65 W.
Support for PoE technology allows NTU-MD500P to supply power via UTP cable to IP phones, wireless access
points, IP cameras and other PoE-enabled devices.
The advantage of GPON technology is the optimum use of bandwidth. This technology is the next step to
provide new high-speed internet connection at home and in offices. Designed to deploy a network inside a
home or building, NTU-MD500P provides reliable connection with high bandwidth over long distances for users
living and working in remote apartment buildings and business centers.
3.2 Overview
NTU-MD500P has the following interfaces:
1 PON SC/APC port for connecting to the operator's network (WAN);
4 Ethernet RJ-45 LAN ports (10/100/1000BASE-T) for connecting network devices (LAN).
NTU-MD500Psupports the following functions:
PoE management and monitoring via OMCI:
ONU-G::PSE overload yellow;
ONU-G::PSE overload red;
Physical path termination point Ethernet UNI::Power control;
Power over Ethernet control::Operational state;
Power over Ethernet control::Power detection status;
Power over Ethernet control::Power classification status;
Power over Ethernet control::Current Power Consumption;

operation in "bridge" or "router" mode;
PPPoE (auto, PAP-, CHAP-, MSCHAP-authorization);
IPoE (DHCP client and static);
DNS (Domain Name System);
DynDNS (Dynamic DNS);
UPnP (Universal Plug and Play);
VPN in L2TP mode;
L2TP over IPsec;
IPsec (trasport mode);
NAT (Network Address Translation);
NTP (Network Time Protocol);
QoS (quality of service mechanisms);
IGMP-snooping;
IGMP proxy;
VLAN according to IEEE 802.1Q.
