Bridging Mode
6.3.1 Introduction to Bridging Principles
In the bridging mode, the ADSL subboard functions only as a
bridge. When data packets pass the ADSL subboard, the subboard
only encapsulates the packets to ATM cells. It transmits data stream
transparently, just like a bridge.
In the bridging mode:
z
The user PC or the IAD108 can initiate the PPP dialing. If the
IAD108 initiates the dialing, the IAD108 can access the
network. If the PC initiates the dialing, the PC can access
the network.
z
If the PC initiates the PPP dialing, it must be first installed
with the PPP dialing software, and then configured with the
user name and password of the PPP dialing. If the IAD108
initiates the PPP dialing, it can be directly configured with
the user name and password of the PPP dialing.
z
When the PC initiates the PPP connection, that is, the PC
accesses the network, one ADSL subboard can connect
multiple PCs. Each PC must have its own user name and
password, to establish independent PPP connection to the
ISN8850.
z
The PPP connection in the bridging mode locates between
the user PC and the BAS (such as Huawei’s ISN8850) of the
