The LAN unique in the telecoms industry

Setup in 2001, the “Laboratoire des Applications Numériques” centers its principal activity in interoperability testing of DSL equipment associated with telephone operators and end-users.

The LAN has developed a reputation with the DSL Forum (now known as the Broadband Forum) as being the point of reference as an ITL (Independent Test Laboratory). In 2005 the LAN merged with the HF Company group, and this facilitated its development and investments in ADSL2+, SHDSL, SHDSL.bis and VDSL2 technologies.

In 2006 a new purpose-built laboratory was built in Tauxigny, near Tours (FRANCE). A large set of DSLAMs, CPEs and test platforms were installed in a dedicated room for xDSL interoperability tests. The set of DSLAMs includes Alcatel-Lucent ASAM and ISAM, Huawei MA5300, MA5600 and MA5600T, Lucent Stinger, ECI High-Focus and much more... This park of DSLAMs and CPEs is regularly up-to-date, following the Network Operators deployments.

It is especially covering the French market by reproducing the exact hardware and software configurations deployed by French Telcos like Orange, SFR, Bouygues Telecom, Completel, etc.

xDSL interoperability tests are now part of the qualification processes of the French Telcos. The LAN infrastructure and services are used when introducing new CPEs or DSLAM releases.

In 2008, the LAN started its activity in the Fiber Access by joining the FSAN Group. The LAN is also especially involved in the Fiber Access Network group of the Broadband Forum on the G-PON interoperability program started in 2010, being coeditor of various test plans like the IR-247 conformance test plan or the TR-255 interoperability test plan.

In 2011, the Broadband Forum has officially selected the LAN as the unique Test Agency authorized to administer the approved BBF.247 tests and to assess eligibility of products for the Broadband Forum BBF.247 Certification.

The LAN continues its interoperability activities around copper and fiber access networks by developing its test services around the coming technologies including FTTdp,, XG-PON1 and Next Generation Passive Optical Network known as NG-PON2.

More than just a test center
A recognised talent in telecommunications

We regroup a recognised expertise and talent in the telecommunication field.
The LAN is an active member of the Broadband Forum. It is an active participant in the elaboration and progress of standards associated with conformity tests, interoperability and performance technologies (high bandwidth DSL and fiber optics).
With this association, we are well placed to provide the most adapted up-to-date testing facilities for your requirements.

What our tests cover

Our xDSL tests cover ADLS to VDSL2 passing through ADSL2+, SHDSL and SHDSL.bis They compose of measures of range, speed, stability and functional tests.

Our G-PON tests cover BBF.247 certification tests and TR.255 interoperability tests.

The LAN partner ships with operators

If you are an Operator then LAN can help you to maintain your DSL network.
We can simulate your infrastructure, and assist you with a test process for new equipment such as CPE’s and DSLAMs in your network, so you can guarantee and maintain their interoperability.
