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.

MAXIMUM DISTANCE BANDWIDTH CAPACITY
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.
Figure 2 Zyxel Device’s Internet Access Application: Ethernet WAN
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.
