3G parameters
Parameter
Description
Enable 3G
network
After enabling the 3G network, you can initiate an H.323 or SIP video
conference using the terminal over the 3G network.
IP address
type
This specifies the mode for obtaining an IP address. The default value is
Dynamic
. It is recommended that you use the default value.
Dynamic
: The terminal obtains an IP address dynamically and
automatically from the network.
Static
: The terminal uses an assigned IP address to connect to a specific
server.
IP address
If
IP address type
is set to
Dynamic
, the IP address assigned by the
server is displayed in this text box only after a Point to Point Protocol
(PPP) connection is established successfully. After being registered with
the GK using the assigned IP address, the terminal can call remote sites
using the relevant numbers, names, or IP addresses over the 3G network.
If
IP address type
is set to
Static
, you can enter the IP address
manually.
Authenticatio
n mode
When the terminal is connected to a 3G network in PPP dial-up mode, the
authentication mode can be set to
PAP
or
CHAP
to prevent the access by
unauthorized users. The default value is
CHAP
. It is recommended that
you use the default value.
If you set the authentication mode to password authentication protocol
(PAP), the user name and the password are transmitted over the network
using plaintext. If the user name and the password are captured during
transmission, the network security is at great risk. Therefore, you can use
the PAP mode when the network security requirement is comparatively
lower.
If you set the authentication mode to the Challenge-Handshake
Authentication Protocol (CHAP), only the user name is transmitted over
the network. Therefore, this authentication mode provides a higher
security level than the PAP mode. In CHAP authentication mode, each
inquiry message for authentication is unpredictable and unique,
preventing recurring network attacks.
