The folks at CableLabs will remain extra busy with the start of certification wave 25, which welcomed a new batch of equipment to be tested for advanced specifications such as DOCSIS 2.0, CableHome 1.0 and PacketCable 1.0.
For DOCSIS 2.0, a specification that widens cable's upstream pipe and mitigates noise, a total of 11 vendors submitted cable modems for the advanced spec: Ambit, Arris, Castlenet, Com21 Inc., Hitron, Linksys, Motorola Broadband, Scientific-Atlanta, Terayon Communication Systems, Thomson and Toshiba. In comparison, CableLabs received five modems for DOCSIS 2.0 in wave 24, the first to officially test product against the spec.
Interestingly, CableLabs did not receive any CMTSs for DOCSIS 2.0 qualification testing. Terayon's BW3500, which uses silicon from the company's Imedia Semiconductor spin-off, remains the only CMTS to have won the DOCSIS 2.0 stamp. Several CMTS vendors that use Broadcom Corp. chipsets have told CED that they don't expect Broadcom's 2.0-based silicon to be ready until the second quarter of this year.
Meanwhile, the PacketCable project reached a milestone of sorts with the launch of wave 25, marking the first to test call management servers (CMSs), or softswitches, against the 1.0 version of the spec.
Three vendors submitted CMSs for the wave: Cedar Point Communications, Cisco Systems Inc. and Syndeo Corp.
Remaining with PacketCable 1.0, CableLabs also received CMTSs from Arris, ADC, Cisco, Motorola Broadband and Terayon, and embedded multimedia terminal adapters (eMTAs) from Arris, Motorola, S-A and Toshiba.
On the CableHome 1.0 front, CableLabs received cable modem gateways from four vendors: Ambit, Linksys, Motorola Broadband and Thomson. To date, Linksys and Netgear are the only manufacturers to win certification for CableHome 1.0, a home networking specification.
Certification wave 25 will conclude on April 4. CableLabs is expected to share results from that wave on or around April 14. Wave 26 is slated to kickoff May 12. Wave 27, the final testing round of 2003, is scheduled to begin September 2.
