CHAPTER 1

Introducing the Zyxel Device

1.1 Overview

Zyxel Device refers to these models as outlined below.

The EX5501-B0 is an Ethernet gateway which provides fast Internet access. I

t has one 2.5 Gbps Multi-

Gigabit Ethernet (GbE) WAN port that is backward compatible with standard Gigabit speed. See

Section 1.1.1 on page 18 for more information on Multi-Gigabit Ethernet. It also has four 1000 Mbps

Ethernet LAN ports.

The AX7501-B0 is an AON (Active Optical Network) while the PX7501-B0 is a PON (Passive Optical

Network) router, which provides fast Internet access. It has one 10 Gbps Multi-Gigabit Ethernet LAN port

and four 1000 Mbps Ethernet LAN ports.

The Zyxel Device also has one USB port that can be configured as a backup WAN port in case the

Cellular/Fiber connection has a problem as well as for file sharing and as a media server. It has two

phone ports to make Internet (VoIP) phone calls.

It also supports dual-band 2.4G / 5G WiFi with WiFi6 that is most suitable in areas with a high

concentration of users. You can schedule Internet usage using Parental Control. See Section on page

96 for more information on WiFi6.

The following table describes the feature differences of the Zyxel Device by model.

1.1.1 Multi-Gigabit Ethernet

A 2.5 Gigabit Ethernet port supports speeds of 2.5 Gbps if the connected device supports 2.5 Gbps.

While a 10 Gigabit Ethernet port supports speeds of 10 Gbps if the connected device supports 10 Gbps

and a Cat 6a (up to 100 m) or Cat 6 cable (up to 50 m) is used.

Some network devices such as gaming computers, servers, network attached storage (NAS) devices, or

access points may have network cards that are capable of 2.5 Gbps or 5 Gbps connectivity.

If these devices are connected to a 1 Gbps or 10 Gbps Ethernet port, they can only transmit or receive

up to 1 Gbps as speeds of 2.5 Gbps / 10 Gbps cannot be attained. Moreover, if network devices with 2.5

Gbps / 10 Gbps network cards are connected to a 2.5 Gbps / 10 Gbps Ethernet port, you must use Cat

5e / Cat 6A or better Ethernet cables to achieve 2.5 Gbps / 10 Gbps speeds. Most buildings, at the time

of writing, use Cat 5e or Cat 6 Ethernet cables.

Multi-Gigabit Ethernet ports automatically allow connections up to the speed of the connected network

device (100 Mbps (not supported on EX5501-B0), 1 Gbps, 2.5 Gbps or 5 Gbps), and you just need to use

a Cat 5, Cat 5e or Cat 6 Ethernet cable.

See the following table for the cables required and distance limitation to attain the corresponding

speed.

1.2 Example Applications

This section shows a few examples of using the Zyxel Device in various network environments. Note that

the Zyxel Device in the figure is just an example Zyxel Device and not your actual Zyxel Device.

1.2.1 Internet Access

The EX5501-B0 has a Gigabit Ethernet port for super-fast Internet access. It provides Internet access by

connecting the WAN port to your ISP.

While the AX7501-B0 / PX7501-B0 provides shared Internet access by connecting a fiber optic cable

provided by the ISP to the PON port. It supports OMCI (ONU Management and Control Interface) to

connect to the ISP’s OLT (Optical Line Terminal).

Computers can connect to the Zyxel Device’s LAN ports (or wirelessly) and access the Internet

simultaneously.

Category 5 100 Mbps 100 m 100 MHz

Category 5e 1 Gbps / 2.5 Gbps / 5 Gbps 100 m 100 MHz

Category 6 5 Gbps / 10 Gbps 50 m 250 MHz

Category 6a 10 Gbps 100 m 500 MHz

Category 7 10 Gbps 100 m 650 MHz

Figure 1 Zyxel Device’s Internet Access Application

You can also configure Firewall on the Zyxel Device for secure Internet access. When the Firewall is on,

all incoming traffic from the Internet to your network is blocked by default unless it is initiated from your

network. This means that probes from the outside to your network are not allowed, but you can safely

browse the Internet and download files.

Connect the WAN port to the broadband modem or router. This way, you can access the Internet via

an Ethernet connection and use the QoS, Firewall and parental control functions on the Zyxel Device.

1.2.2 Dual-Band WiFi

By default, WiFi is enabled on the Zyxel Device. IEEE 802.11a/b/g/n/ac/ax compliant clients can

wirelessly connect to the Zyxel Device to access network resources.

The Zyxel Device is a dual-band gateway that can use both 2.4G and 5G networks at the same time.

You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz

band for time sensitive traffic like high-definition video, music, and gaming.

Figure 3 Dual-Band Application

The Zyxel Device is a wireless Access Point (AP) for IEEE 802.11b/g/n/a/ac/ax wireless clients, such as

notebook computers, iPads, smartphones, and so on. It allows them to connect to the Internet without

having to rely on inconvenient Ethernet cables.

Your Zyxel Device supports WiFi Protected Setup (WPS), which allows you to quickly set up a wireless

network with strong security.

Figure 4 Wireless Access Example

1.2.3 VoIP Applications

The Zyxel Device’s VoIP function allows you to register up to 2 SIP (Session Initiation Protocol) accounts

and use the Zyxel Device to make and receive VoIP telephone calls. The Zyxel Device sends your call to

a VoIP service provider’s SIP server which forwards the calls to either VoIP or PSTN phones.
