When a customer migrates from ADSL2+ or VDSL2 to PON or WiMAX, the ISP
only needs to install a simple and relatively cheap bridge-device to terminate
the physical connection and provide an Ethernet-interface towards the
customer. The customer’s existing P-2812HNU(L)-Fx will still able to be used
for terminating the IP-connection, but now via the Ethernet WAN-interface.
The end-users can still enjoy the services provided by their original CPE,
