Chapter 3: Connections and setup
Activating the EMTA
After you install the EMTA and turn it on for the first time (and each time the modem is reconnected to
the power), it goes through several steps before it can be used. Each of these steps is represented by a
different pattern of flashing lights on the front of the modem.
Note: All indicators flash once prior to the initialization sequence.
If all of the lights are flashing sequentially, it means the EMTA is automatically updating its system
software. Please wait for the lights to stop flashing. You cannot use your modem during this time. Do
not remove the power supply or reset the EMTA during this process.
To make sure that you can access the Internet successfully, please check the following first.
1. Make sure the connection (through Ethernet) between the EMTA and your computer is OK.
2. Make sure the TCP/IP protocol is set properly.
3. Subscribe to a Cable Company.

This is set by different actions (non exhaustive list):
- at the manufactory level,
- following a reset factory on the modem,
- following a reset from the operator,
- following a change by the user who wants to come back to
the default setting after using its own settings
When the current password is the default one, the user is strongly encouraged to change the default
web password.
At your first connection or while the password is the default one, a warning message is displayed on the
top banner of each Web configuration page. We want to encourage you to change the password in order
to enforce the security of your modem.
The password can be a maximum of 8 characters and is case sensitive. In addition, this page can be used
to restore the gateway to its original factory settings. Use this with caution, as all the settings you have
made will be lost. To perform this reset, set Restore Factory Defaults to Yes and click Apply. This has
the same effect as a factory reset using the rear panel reset switch, where you hold on the switch for 5
seconds, then release it.
Note: We are always suggesting you to modify the password. This is a basic protection against wrongful
access to the Gateway Web pages.

Diagnostics
This page offers basic diagnostic tools for you to use when connectivity problems occur. When you ping
an Internet device, you send a packet to its TCP/IP stack, and it sends one back to yours. To use the ping
Test, enter the information needed and press Start Test; the Result will be displayed in the lower part of
the window. Press Abort Test to stop, and Clear Results to clear the result contents. Note: Firewalls may
cause pings to fail but still provide you TCP/IP access to selected devices behind them. Keep this in mind
when ping a device that may be behind a firewall. Ping is most useful to verify connectivity with PCs
which do not have firewalls, such as the PCs on your LAN side.

Chapter 3: Connections and setup
IPsec PassThrough enables IPsec type packets to pass between WAN and LAN. IPsec (IP Security) is a
security mechanism used in Virtual Private Networks (VPNs).
PPTP PassThrough enables PPTP type packets to pass between WAN and LAN. PPTP (Point to Point
Tunneling Protocol) is another mechanism sometimes used in VPNs.
Remote Config Management makes the configuration web pages in your gateway accessible from the
WAN side. Note that page access is limited to only those who know the gateway access password. When
accessing your gateway from a remote location, your must use HTTP port 8080 and the WAN IP address
of the gateway. e.g., if the WAN IP address is 157.254.5.7, you would navigate to
http://157.254.5.7:8080 to reach your gateway.
Multicast Enable enables multicast traffic to pass through WAN and LAN. You may need to enable this
to see some types of broadcast streaming and content on the Internet.
UPnP Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.
NAT ALG enable NAT ALG (application layer gateways) allows customized NAT traversal filters to be
plugged into the gateway to support address and port translation for certain application layer
"control/data" protocols such as RSVP, FTP, TFTP, Kerb88, NetBios , IKE, RTSP, Kerb1293 , H225 , PPTP ,
MSN , SIP , ICQ , IRC666x , ICQTalk , Net2Phone , IRC7000 , IRC8000 file transfer in IM applications etc. In
order for these protocols to work through NAT or a firewall, either the application has to know about an
address/port number combination that allows incoming packets, or the NAT has to monitor the control
traffic and open up port mappings (firewall pinhole) dynamically as required. Legitimate application data
can thus be passed through the security checks of the firewall or NAT that would have otherwise
restricted the traffic for not meeting its limited filter criteria.

Forwarding
For LAN Ù WAN communications, the gateway normally only allows you to originate an IP connection
with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection onto your PC.
This protects you from malicious attacks from outsiders. However, sometimes you may wish for anyone
outside to be able to originate a connection to a particular PC on your LAN if the destination port
(application) matches one you specify.

Port Triggers
Some Internet activities, such as interactive gaming, require that a PC on the WAN side of your gateway
be able to originate connections during the game with your game playing PC on the LAN side. You could
use the Advanced-Forwarding web page to construct a forwarding rule during the game, and then
remove it afterwards (to restore full protection to your LAN PC) to facilitate this. Port triggering is an
elegant mechanism that does this work for you, each time you play the game.

WPA (Wi-Fi Protected Access)/WPA2:
It must be used in connection with an authentication server such as RADIUS to provide
centralized access control and management. It can provide stronger encryption and
authentication solution than none WPA modes. WPA2 is the second generation of WPA security.
There are two types for choose AES and TKIP+AES.
TKIP (Temporal Key Integrity Protocol): Takes the original master key only as a starting point and
derives its encryption keys mathematically from this mater key. Then it regularly changes and
rotates the encryption keys so that the same encryption key will never be used twice.
AES (Advanced Encryption Standard): This Provides security between client workstations
operating in ad hoc mode. It uses a mathematical ciphering algorithm that employs variable key
sizes of 128, 192 or 256 bits.
RADIUS (Remote Authentication Dial In User Service) Server:
a protocol for carrying authentication, authorization, and configuration information between a
Network Access Server which desires to authenticate its links and a shared Authentication Server.
Please key in the IP Address for the RADIUS Server.
RADIUS (Remote Authentication Dial In User Service) Port:
Besides the IP address of the RADIUS Server, you have to enter the port number for the server.
Port 1812 is the reserved RADIUS-authentication port described in RFC 2138. Earlier AP (RADIUS
clients) use port 1945. The default value will be shown on this box. You can keep and use it.
RADIUS (Remote Authentication Dial In User Service) Key:
A RADIUS Key is like a password, which is used between IAS and the specific RADIUS client to
verify identity. Both IAS and the RADIUS client must be use the same RADIUS Key for successful
communication to occur. Enter the RADIUS Key.
Group Key Rotation Interval:
Key in the time for the WAP group key rotation interval. The unit is second. With increasing rekey
interval, user bandwidth requirement is reduced
WPA/WPA2 Re-auth Interval:
When a wireless client has associated with the Wireless Voice Gateway for a period of time
longer than the setting here, it would be disconnected and the authentication will be executed
again. The default value is 3600, you may modify it
WPA-PSK (WPA-Pre-Shared Key) /WPA2-PSK:
Its useful for small places without authentication servers such as the network at home. It allows
the use of manually-entered keys or passwords and is designed to be easily set up for home
users.
Please type the key to be between 8 and 63 characters, or 64 hexadecimal digits. Only the
