connect to the office Router/Firewall.
Figure 3. MTA8328-MP business models (4, 8, and 24 FXS port models)
1.3 Residential Models: Out of the Box Setup
This section provides a step-by-step guide to install the MTA and setup the system for connecting to a
broadband network. Before starting the Installation, make sure your broadband Internet access device is
powered on and your connection is up. (Check your Internet service provider’s documentation).
Note that the Ethernet connection setup applies to MTA8338-1N, MTA8328-1N and MTA8328-1W models;
whereas the WiFi connection setup applies to MTA8328-1W only.

Plug the supplied power adapter into the MTA. The power LED will show steady green.
Connect your phone into the PHONE port on the MTA using the supplied Phone Cable.
Setup the MTA to connect to your Home Router.
•For Ethernet Connection. If your MTA is located close to your Home Router, connect the yellow
Ethernet cable (supplied) into the WAN port on the MTA and connect the other end into an available
Ethernet port on your router or LAN network. Then proceed to step directly.
•For WiFi Connection. Alternatively, connect the MTA to the Home Router through a WiFi connection.
You will connect the MTA to a WiFi Access Point using your smartphone, tablet or PC. Press the round
button on the top of the unit for about 5 seconds, the MTA will switch to “Setup Mode” and the WiFi
LED will change to solid yellow. Connect your smartphone or PC to the MTA’s preset SSID shown on
the back of the unit, i.e., MTA8328-xxxxxx, product name followed by the last 6 digits of MAC
address. The MTA welcome portal web page will show up on your smartphone/PC. If this page does
not popup, open a web browser and type in the following address: http://192.168.199.1/wifisetup/
During setup, follow the instructions on the welcome portal. You will need to select the WiFi SSID of
your WiFi Access Point and input the WiFi passphrase. For detailed instructions, please see Appendix
C: WiFi Connection Setup through Captive Portal.
Confirm that the MTA is successfully connected to the Home Router and acquires an IP address as follows:
For Ethernet Connection. The WAN LED shows green for 100BT connection, or shows amber for 10BT.
For WiFi Connection. The WiFi LED shows green. If it is not green, repeat step .
Once the MTA connects to the voice service provider network, and completes the registration and service
provision process, you should see a solid green PHONE LED light displayed.
1.3.1MTA8328-1W WiFi Connection Optimizer (WCO) Test
This feature applies to the MTA8328-1W only. The WCO test is designed to determine an ideal location for
the MTA by performing voice quality validation thru a WiFi connection
2
. One of the following results will be
displayed/announced after the WCO test is completed:
Your device location is Excellent|Good|Not Good
If the test result is “Not Good”, one or more of the following steps are recommended before running the
WCO test again until the result is “Good” or “Excellent”:
•Change the location of the MTA. Decrease the distance between the MTA and the WiFi router
and/or avoid any large obstructions between the MTA and WiFi router.
•Switch to another WiFi channel.
•Change WiFi frequency between 2.4GHz and 5 GHz to improve reception.
Note:
•The WCO test can only be invoked when the WAN Ethernet is not connected.
•Run the WCO test only when the WiFi LED displays solid green as its initial state.
2
Note that some WiFi routers may drop WCO packets for strict security configurations.

InnoMedia MTA8000 Series Administrative Guide

•The WCO test will run for 30 seconds. During a test period, the WiFi LED changes its state to
“blinking yellow” (0.5 sec ON | 0.5 sec OFF).
Execute the WCO test using any of the following three approaches:
Method 1: Dial ***8 from the phone connected to the MTA.
Off hook the phone, dial ***8, and the MTA Interactive Voice Response (IVR) will play “Wireless connection
optimizer test is in progress, please wait…” After the test is complete, the IVR will then announce the test
result, as well as displaying it through its respective LED state, as shown in LED State
Method 2: Double click the round button on the top of the MTA box
Double click the round button on the top of the unit. After the WCO test is complete, the result is displayed
through its respective LED state, as shown in LED State
Method 3: Device administrative WEB console
Login to the MTA administrative web console (Figure 7). Navigate to Telephony > Wireless Connection
Optimizer page, and click the <Start Test> Button. The test result will be displayed on the WEB GUI page
(Figure 5) as well as through its respective LED state, as shown in
Table 1: WCO Result-LED State.
Figure 5. WCO test result

1.4 Business Models: Out of the Box Setup
Figure 6. Setup the MTA in a business environment
Plug the supplied power adapter into the MTA. The power LED will show steady green.
Connect phones or other analog devices into the PHONE X port on the MTA.
Setup the MTA to connect to the Internet. Connect the yellow Ethernet cable (supplied) into the WAN
port on the MTA and connect the other end into an available Ethernet port on your router or LAN
network switch.
Confirm that the MTA is successfully connected to the Router and acquires an IP address. If the WAN LED
shows steady green, it is connected.
•The MTA WAN interface is configured as DHCP client by factory default so that it can obtain an IP
address from the corporate DHCP server.
•When a static IP address is needed, refer to section 2 to login to the MTA web console and configure
the WAN interface accordingly.
Once the MTA connects to the voice service provider network, and completes the registration and service
provision process, you should see a solid green PHONE LED light displayed.
1.5 Terminology and Usage
1. The supported character set of the device text input box: 7 bit ASCII.

2HOME -- DEVICE STATES
The MTA can be managed via a Web Browser interface. Once the MTA is connected to the network, connect
a device with a browser to the same router as the MTA WAN interface, or directly connect the device to the
MTA LAN interface. Access and configure the MTA via a Web Browser.
The IP address of the Ethernet LAN interface is 192.168.99.1.
Press ***1 on a phone connected to the MTA and the IP address of the MTA WAN interface will be played
through the telephone handset.
When the Ethernet WAN interface is connected to the Router, the IP address played is always the Ethernet
WAN IP; otherwise, the WiFi WAN IP address will be played if a WiFi connection has been setup.
The default Admin Username is: admin
The default Password is: password
The default end user Username is: user
The default Password is: welcome
Note: The username and password could be different if changed by the service provider. They also could be
changed through service provisioning process, Please refer to the user’s guide of provisioning system
provided by specific vendors..
