4 Installing the QX Gateways
4.1 Networking Overview
To establish connections between the PSTN (or the legacy PBX) and the Internet, a gateway is needed. The QX
gateway, used as a stand-alone device, will perform the task of connecting the PSTN (or PBX) to a Private Data
Network or the Internet. The QX gateway will process and regulate the voice traffic between these networks
according to specified dial plan.
Figure 7: Stand-alone gateway (QXFXO4, QXE1T1 or QXISDN4): Connection overview
Figure 8: Stand-alone gateway (QXFXS24): Connection overview

Manual-I: Installation Guide for QX Gateway
Revision 1.2 11
Figure 9: Stand-alone gateway with Legacy PBX (QXFXS24): Connection overview
Every device within an IP network requires a unique IP address to identify itself. Since the QX gateway, used as
a stand-alone gateway, connects to both the LAN (Admin PC) and the WAN (Private Data Network or Internet),
it has to be part of both networks, and must have two IP addresses: one for the WAN side and one for the LAN
side. The QX gateway’s integrated firewall/NAT functionality will hide the LAN IP address from the WAN side.
There are two types of IP addresses:
Static – a fixed, manually assigned IP address that remains valid until changed. If you plan to use the QX
as your router, contact your Internet Service Provider (ISP) to find out if a static IP address is assigned to
your account. If so, you will need this static IP address when configuring the QX device.
Dynamic – a temporary address that is automatically assigned by your ISP and will change periodically. If
your ISP offers a dynamic IP address, the QX will act as a DHCP client and will receive a new IP address
from the ISP’s DHCP server or PPPoE feature.
Note: A DHCP client is a service that requests an IP address from a DHCP server. A DHCP server assigns on
request a unique IP address to a device. The QX, like many routers, acts as a DHCP client on its WAN interface
and as a DHCP server on its LAN interface.
Besides acting as a stand-alone device, QX gateways may serve as a PSTN LINE expansion for QX IP PBXs. In
this case, the QX gateway gets a WAN IP address from the DHCP server of the connected QX IP PBX.

4.2 Connecting the Hardware
Verify the product package contents are complete. Refer to the contents sheet included in the packaging to
determine if all the items were shipped in the box.
1. Connect the Ethernet port on your PC via a straight CAT 5 cable with an RJ45 connector to the LAN
socket of the QX.
2. Connect PSTN Lines to FXO, E1T1 or ISDN interface ports on the QX.
3. Connect the LAN port on your PC via a straight CAT 5 cable with an RJ45 connector to the LAN socket
of the QX.
4. Connect the WAN port of the QX to the ISP network.
5. Connect the power cable to a power strip with surge protection and a UPS.
6. Power up any hub or switch followed by any PC and other devices on the LAN side.
7. Check the LEDs: The green WAN LED will blink when cables are connected to these ports and all de-
vices are powered up. If the green WAN LED does not blink, verify cabling and ensure that all devices
are powered up.
Note: CAT 5 cables can be faulty without any visual indication. The LAN and WAN LEDs verify that the Ethernet
connection is established between the end points. If these LEDs are not illuminated, there is a connection prob-
lem between the QX and the other device.
5 QX Configuration (Stand-alone Mode)
Verify functionality of both IP and PSTN calls:
PSTN telephony: If the QX is connected to the PSTN network via the E1/T1, FXO or ISDN interface, verify
the functionality of PSTN calls:
Make an outbound PSTN call by dialing PSTN number.
Arrange to receive an incoming call. The incoming PSTN calls will be routed to the Auto Attendant by
default.
Bandwidth – to regulate the number of calls allowed by the QX to avoid degradation in low bandwidth
conditions.
Time/Date – to ensure the correct time and time zone are used for call records.
Regional Settings – if your QX is located outside the United States, it is important to properly configure
your line connections to the PSTN in your location.

5.1 Logging in to QX Gateway
1. Start a browser (Google Chrome, Opera, Mozilla Firefox, etc.) on a PC connected to the QX.
2. Since Firewall is disabled on the QX by default, you may connect the Web GUI either from WAN or LAN
side of the QX. To connect the QX’s Web GUI from the WAN side, enter http://xxx.xxx.xxx.xxx (IP ad-
dress assigned by the company’s DHCP server) in the address field of your browser. If the PC is con-
nected to the QX’s LAN side, enter the 172.28.0.1 address in the address field of your browser.
3. The Login page of the QX will be displayed.
Figure 12: Login page
4. Enter the default credentials (Username: admin and Password: 19) to log into the QX WEB GUI as an
administrator. Note: If you consecutively enter a wrong password and/or username for five times the de-
vice will be unavailable for login for five minutes.

Revision 1.2 15
5.2 Basic Setup - System (LAN)
Navigate to the SetupBasic SetupSystem (LAN). The System Configuration Wizard defines the QX's LAN set-
tings and specifies regional configuration. The System Configuration Wizard must be run upon QX first startup.
Some sections in this wizard may be skipped and left default for the basic configuration.
Note:It is strongly recommended to leave the factory default settings unchanged if their meanings are not
completely understandable to the party administrating the QX.
System Configuration
Enter the unique name into the Hostname field and the LAN side domain name (to which the QX belongs to)
into the Domain Name text field. The LAN IP Address doesn’t need to be changed for a basic configuration. For
more advanced configuration, record a new LAN IP Address and keep it handy, you will need it for subsequent
access to the QX’s WEB GUI.
Figure 14: System Configuration section
DHCP Settings for the LAN Interface
Enabled DHCP server allows the QX automatically assign dynamic IP addresses to the devices on its LAN side.
If you haven't changed the default LAN IP address of the QX, you also may leave the default values for the IP
Address Range. TIP: Make sure your connected LAN devices belong to the same network as the LAN port of
your QX. Make sure there is only one DHCP server on the LAN, otherwise, unpredictable network behavior can
occur.

Revision 1.2 16
Figure 15: DHCP Settings for the LAN Interface section
Regional Settings and Preferences
If your QX is located outside of the United States, it is important to properly configure your line connections to
the PSTN in your location.
Figure 16: Regional Settings and Preferences section
Proper configuration of the Regional Settings is important for the functionality of the voice subsystem. The Re-
gional Settings determine the proper telephony parameters on the Line/Trunk and Phone ports of the QX for the
specified country. Select the country where the QX is located. If you do not find your country in the list, pick the
closest in your timezone. The QX obtains the correct time automatically over the Internet from a time server. If
you are not located in the US/Central standard time zone, you will need to change the Timezone to your region.

Summary Page
Finish the wizard and click "OK" to apply the changes made in any section of the wizard. You must con-
firm the settings within 20 minutes. Otherwise the device will return back to the previous configuration
and reboot.
If you do not use DHCP for your LAN and you have changed your LAN settings, make sure that the IP
address of the PC connected to QX is still within the specified IP address range, otherwise your PC may
not establish a connection to QX.
If you changed the network configuration of the LAN, restart your LAN connection to receive a new IP
address from the new network. Then you can access the Web Management of the QX on the new IP
address you’ve assigned to the QX.
5.3 Internet (WAN)
Go to the SetupBasic SetupInternet (WAN) to configure the network parameters for the WAN interface and
adjust QX’s connectivity to an external network. The Internet Configuration Wizard defines WAN settings and
adjusts QX's connectivity to the global network. It must be run if QX is desired to be connected to the Internet.
Before configuring the WAN port to the Internet, you need to get the following information from your internet
service provider:
Bandwidth – the available upstream and downstream.
WAN IP Configuration – is DHCP supported? If yes, no more information is needed. If DHCP is not sup-
ported, the following data is needed: the WAN IP address, the subnet mask, the IP address of the de-
fault gateway and the IP address of the Domain Name Server (DNS).
MAC address – needed when the ISP requires a specific MAC address for the WAN.
Additionally, for Point-to-Point Protocol over Ethernet (PPPoE) WAN interface, you need to get the following in-
formation from your internet service provider:
PPP Configuration – does your ISP use a dynamic or fixed WAN IP address? If the WAN IP address is
dynamic, no more information is needed. If the WAN IP address is fixed, you will have to enter it.
Authentication – does your ISP require authentication? If authentication is required, information about
the corresponding method (PAP, CHAP or MSCHAP) is needed including the username and password
of the PPPoE account.
This information will be needed to be inserted in the Internet Configuration Wizard.
Uplink Configuration
Select the desired WAN Interface Protocol and enter the WAN Interface Bandwidth to assure the quality of IP
calls.
If the available bandwidth is used to the point where the quality of an additional IP call would suffer, then new IP
calls are rejected. The bandwidth provided by your ISP must be specified for both Upstream and Downstream
fields. The default entry in both fields is 100000, the maximum bandwidth of the 100 Mb uplink module. For
basic DSL and cable modem service in the United States, typical values are 300 for Upstream and 1500 for
Downstream. The Min Data Rate text field is used to specify the amount of bandwidth reserved for data appli-
cations. The value entered here needs to be smaller than the value specified for Upstream Bandwidth.
Select the WAN Interface Protocol by choosing between available WAN interface protocols: PPPoE (Point to
Point over Ethernet), PPTP (Point to Point Tunneling Protocol), Ethernet and VLAN.
Based on this selection the wizard's configuration pages may differ.
