Makers of the technical components that will populate cable's IP telephony networks lined up to take PacketCable to the test at CableLabs in certification wave 27, the last one scheduled for 2003.

On the home side of the network, Scientific-Atlanta submitted an embedded multimedia terminal adapter (eMTA) for PacketCable 1.0 testing.

Three vendors — Cedar Point Communications, Cisco Systems and Telcordia Technologies — supplied call management servers (CMS), considered the brains of the VoIP network.

Cedar Point and Cisco won PacketCable 1.0 qualification for their respective softswitches in previous waves. Both are testing new software releases for those products — the Cedar Point Safari C3 and the Cisco BTS 10200.

Cisco, according to a CableLabs CW27 document also submitted a media gateway controller for PC 1.0 testing. It will be joined by General Bandwidth's G6 platform, which is undergoing PacketCable testing for its media gateway function.

On the DOCSIS 2.0 front, CableLabs received cable modem models or reference designs from Linksys (now part of Cisco), Conexant and Terayon Communication Systems.

Although no cable modem termination systems (CMTSs) were listed by CableLabs for DOCSIS 2.0 qualification testing in the current wave, at least one vendor plans to join the party very soon. ADC, which launched a module for its flagship Cuda 12000 CMTS based on Broadcom Corp.'s DOCSIS 2.0-based chipset, will enter the testing fray by early next week, a company spokesman said.

To date, Terayon is the only CMTS vendor to win DOCSIS 2.0 qualification.

In wave 27, CableLabs will also conduct DOCSIS 1.1 testing on CMTSs from Motorola Broadband and Cisco. Motorola also submitted a cable modem gateway that will undergo testing for both CableHome 1.0 and DOCSIS 2.0.

Wave 27 is scheduled to end November 7. CableLabs is expected to share the results on or around November 17.
