Test Setup for LTE Gateway or Mobile Hotspot

Now that mobile data connections have reached speeds acceptable for broadband access, more and more devices are using LTE as either their primary or backup WAN connection. As more devices get pushed into the home, this number will likely increase by quite a bit. How do you test routers and gateways with LTE WAN connections, that have all of the same testing needs as other home and enterprise broadband gateways? Read more...

DOCSIS Cable Gateway Testing in a Shared Lab Enviroment

With the DOCSIS add-on, CDRouter is perfectly suited for testing and verifying the higher layer network functionality of a DOCSIS-based device under test (DUT). The basic CDRouter test setup for cable gateways is very similar to the test setup for DSL-based gateways. Like the DSL test setup, CDRouter does not have the ability to terminate a cable gateway’s HFC WAN connection directly. As a result, a CMTS must be included in a cable gateway test setup, as opposed to a DSLAM for DSL gateways. Read more...

Testing devices with wireless WAN connections

At QA Cafe we continuously see new consumer broadband and home network devices come into the market and into our lab. One of the newest class of devices are “travel routers” - routers that are popular with people who frequently connect to public Wifi networks or those offered by hotels, restaurants, or hospitals. These devices let you preserve network settings that your devices need, let you set up default connections to VPNs or other secure networks, and act as an additional level of firewall security when connecting to public networks.

Testing to reduce the big three broadband customer support problems

The most well understood case for product testing is in quality assurance while a home networking product is in development, or testing its integrity between firmware revisions. But testing before, during, and after deployment can also ensure that service providers reduce costly support calls and truck rolls. We asked some of our customers, some in the service provider world and others who develop management and support services for service providers, what the most common causes of service calls are.

Testing Setup for a Gateway with a MoCA Bridge WAN

CDRouter can be used with routers that have a Multimedia over Coax Alliance (MoCA) interface through the use of an external MoCA bridge. the MoCA bridge is essentially a media converter with Ethernet on one side and MoCA on the other. It bridges packets from a MoCA network to Ethernet and vice-versa. ] In this setup CDRouter connects directly to DUT’s LAN interface and the MoCA bridge via Ethernet. The MoCA bridge is then connected to the DUT’s MoCA WAN interface. Read more...

Bridge mode testing with CDRouter

CDRouter includes support for testing basic Layer 2 bridging devices including wireless access points, broadband access devices, and Ethernet switches. CDRouter can be used to verify the following functionality of a DUT operating in bridge mode: IPv4 and IPv6 forwarding TR-069 client 802.1x port based authentication VLAN functionality Basic Configuration To enable bridge mode within CDRouter, set the testvar forwardingMode to bridge. This testvar supports two values, route for routing devices or bridge for Layer 2 bridging devices. Read more...

Configuring CDRouter for 802.1x Authentication on the WAN

CDRouter includes support for configurations involving 802.1X authentication on the WAN. 802.1X is typically used by service providers to authenticate a client or device and open a port on an 802.1X enabled DSLAM or switch for CPE traffic. CPE devices that support 802.1X on the WAN must include 802.1X supplicant functionality in addition to common IPv4 and IPv6 WAN connectivity options such as DHCP and PPPoE. About IEEE 802.1x IEEE 802. Read more...
