CHAPTER 1
Introducing the Zyxel Device
1.1 Overview
The Zyxel Device refers to these models as outlined below.
The AX7501-B0 is an AON (Active Optical Network) while the PX7501-B0 is a PON (Passive Optical
Network) router.
The DX Series are DSL routers, which provide Internet access over telephone lines.
The EX Series are Ethernet gateways/routers that provide Internet access through the Ethernet WAN port
or an SFP port.
The Zyxel Device (referring to all Series models in this User’s Guide) has one USB port that can be
configured as a backup cellular WAN port in case the Ethernet/Fiber/DSL connection has a problem as
well as for file sharing and as a media server. The Zyxel Device also supports WiFi6 that is most suitable in
areas with a high concentration of users. You can schedule WiFi usage using Parental Control.
For Zyxel Devices that support 2.5 Gbps Multi-Gigabit Ethernet (GbE) WAN/LAN ports, the port speeds
are backward compatible with standard Gigabit speed. See Section 1.1.1 on page 22 for more
information on Multi-Gigabit Ethernet. The Zyxel Devices with an SFP port can also provide Internet
access through a Multi-Gigabit GPON WAN connection. See the following table for the features that
your Zyxel Device supports.
The following table describes the feature differences of the Zyxel Device by model.
• AX7501-B0 • EX3300-T0 • EX5501-B0 • PX7501-B0
• DX3300-T0 • EX2210-T0 • EX5600-T1
