ROUTING MODE

When your CGN is in routing mode, it acts as a gateway for computers on the LAN to

access the Internet. The service provider assigns an IP address to the CGN on the

WAN, and all traffic for LAN computers is sent to that IP address. The CGN assigns

private IP addresses to LAN computers (when DHCP is active), and transmits the

relevant traffic to each private IP address.

NOTE:

When DHCP is not active on the CGN in routing mode, each computer on the

LAN must be assigned an IP address in the CGN's subnet manually.

When the CGN is not in routing mode, the service provider assigns an IP address to

each computer connected to the CGN directly. The CGN does not perform any

routing operations, and traffic flows between the computers and the service provider.

Routing mode is not user-configurable; it is specified by the service provider in the

CGN's configuration file.

2.1.7

The CGN's configuration (or config) file is a document that the CGN obtains

automatically over the Internet from the service provider's server, which specifies the

settings that the CGN should use. It contains a variety of settings that are not present

in the user-configurable Graphical User Interface (GUI) and can be specified only by

the service provider.

2.1.8

The terms "downstream" and "upstream" refer to data traffic flows, and indicate the

direction in which the traffic is traveling. "Downstream" refers to traffic from the

service provider to the CGN, and "upstream" refers to traffic from the CGN to the

service provider.

2.1.9

Just like radio transmissions, data transmissions over the cable network must exist

on different frequencies in order to avoid interference between signals.

The data traffic band is separate from the TV band, and each data channel is

separate from other data channels.
