PPP Dialing
The ADSL subboard can also complete the PPP dialing. During
the dialing, the ADSL subboard works in the non-bridging mode and
initiates the PPP connection. Configure a user name with a password
for the PPP dialing on the ADSL subboard.
In addition, the ADSL subboard can provide the NAT service and
serve as a DHCP server or a router. Basically, no configuration is
needed for the use of the ADSL subboard in the Ethernet. If needed,
you can configure the DHCP address pool and routing information.
6.1.3 Connecting Uplink Interface
After all hardware for ADSL applications is installed, you can
connect the IAD108 uplink interface, to implement the physical
connection between the IAD108 and upper equipment.
When the IAD108 provides ADSL services, it is connected to the
uplink device only through the RJ-11 telephone interface in the ADSL
mode. The uplink Ethernet port on the back panel can only be used as
the RJ-11 telephone interface.
6.1.4 Connecting Downlink Interface
Compared with the connection of the downlink interface of the FE
uplink mode, that of the ADSL uplink mode has no change. The two
RJ-45 network ports on the back panel can only be connected to the
PC. The eight RJ-11 POTS interfaces can only be connected to the
user telephone.
