Using CDRouter in an FTTdp Deployment with G.fast

New broadband access topologies come along every day that are making it easier for service providers to provide fiber quality broadband services without running fiber all the way to the home. One of these topologies is referred to as “Fiber to the Drop Point (FTTP)”, and does precisely this: allowing fiber to be run to a Drop Point Unit, where it is broken out into VDSL2 or G.fast (the lastest and fastest DSL based transition technology.

DSL CPE Testing with CDRouter

CDRouter is the ideal tool for testing the higher layer functionality of DSL based CPE. With a few additions to the basic test setup, CDRouter can be used to test CPE utilizing any type of DSL or G.fast devices. Overview The test setup for DSL CPE devices is similar to the test setup for typical Ethernet-to-Ethernet routers, with one exception. Since CDRouter does not have the ability to terminate the CPE device’s DSL connection directly, a dedicated DSLAM must be included in the test setup. Read more...

Can I use CDRouter if my router has a built in xDSL interface?

Yes, although CDRouter does not support the termination of DSL interfaces directly. If the WAN interface on your router is DSL-based (ADSL/2/2+, VDSL/2, SDSL, SHDSL/SHDSL.bis, G.fast, etc.) as opposed to Ethernet-based, you have two main options. Option 1: Use an Ethernet/IP DSLAM and connect the Ethernet uplink port of the DSLAM directly to CDRouter’s designated WAN interface. In this configuration the DSLAM must be configured to terminate the ATM connection on the DSL interface and bridge all network traffic from the DSL interface to the uplink port. Read more...
