SIM Card Setting
PIN Code This field displays with a GSM or HSDPA 3G card. A PIN (Personal Identification
Number) code is a key to a 3G card. Without the PIN code, you cannot use the 3G card.
Enter the 4-digit PIN code (0000 for example) provided by your ISP. If you enter the
PIN code incorrectly, the 3G card may be blocked by your ISP and you cannot use the
account to access the Internet.
If your ISP disabled PIN code authentication, enter an arbitrary number.
Interface
Parameters
Egress
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the ISG50 can send
through the interface to the network. Allowed values are 0 - 1048576. This setting is
used in WAN load balancing and bandwidth management.
Ingress
Bandwidth
This is reserved for future use.
Enter the maximum amount of traffic, in kilobits per second, the ISG50 can receive
from the network through the interface. Allowed values are 0 - 1048576.
MTU Maximum Transmission Unit. Type the maximum size of each data packet, in bytes, that
can move through this interface. If a larger packet arrives, the ISG50 divides it into
smaller fragments. Allowed values are 576 - 1492. Usually, this value is 1492.
Connectivity Check The interface can regularly check the connection to the gateway you specified to make
sure it is still available. You specify how often the interface checks the connection, how
long to wait for a response before the attempt is a failure, and how many consecutive
failures are required before the ISG50 stops routing to the gateway. The ISG50
resumes routing to the gateway the first time the gateway passes the connectivity
check.
