The Euro-DOCSIS Certification Board has granted its first Euro-DOCSIS 1.1 certification to Toshiba's PCX2500 cable modem.

The board also granted Euro-DOCSIS 1.1 qualification status to the Arris Cadant C4 CMTS. Both companies resubmitted their products for testing in the certification wave 8 after minor problems were found during wave 7.

The Euro-DOCSIS Certification Board consists of representatives of European cable operators Casema, NetCologne, NTL, Telenet, Telewest and UPC. The board expects to certify other modems in the near future.

In the United States, several vendors have received DOCSIS 1.1 certification and are selling DOCSIS 1.1-certified modems or reference designs, including 3Com, Aastra, Accton, Ambit, Arris, Askey, Com21, Conexant, Correlant, Joohong, Motorola Broadband (three models), Quanta Network Systems, Samsung, Scientific-Atlanta, Tellabs, Terayon, Texas Instruments, Thomson, Toshiba, and Xrosstech.

CableLabs has also qualified CMTSs from the following manufacturers: ADC, Arris, Cisco, Juniper Networks, Motorola Broadband, Riverstone Networks and S-A.

The DOCSIS 2.0 specification was finalized in January and is now in the interoperability phase. DOCSIS 2.0 is an advanced physical layer addition to modem functions. The spec can increase upstream bandwidth for cable modems to 30 megabits per second — three times that of DOCSIS 1.1 units.
