Motorola is targeting mid-2010 for a high-density module for its BSR 64000 integrated cable-modem termination system that would provide 48 ports of upstream capacity -- dramatically increasing the upload speeds possible through DOCSIS 3.0 technology.
This week, the company expects to release software 5.2 for the BSR 64000, which provides system-wide high-availability and service assurance and doubles downstream capacity, with support for two TX32 modules per chassis.
Each Motorola TX32 downstream module supports 32 QAM channels in a single slot in the CMTS, to deliver DOCSIS 3.0 channel-bonded services of up to 200 Mbps downstream.
Next on Motorola's to-do list is to increase upstream capacity, said Floyd Wagoner, director of global marketing and communications for Motorola's Access Networks Business.
The company is developing a module, the RX48, which would provide 48 upstream ports per chassis slot. Motorola is aiming to deliver that to the market by the middle of next year. "We're going to have the card and the technology when the market's ready for it," Wagoner said.
Motorola is also using synchronous code division multiple access technology to reduce noise in the spectrum below 20 MHz for upstream DOCSIS 3.0 channels, Wagoner said. "If the battle on upstream is ‘I need more,' it's important to clean up the spectrum so you can reach below 20 MHz," he said. "It's a more thoughtful approach than just throwing hardware at it."
Motorola's DOCSIS 3.0 "bronze-qualified" BSR 64000 CMTS is backward-compatible with DOCSIS 1.0, 1.1 and 2.0 standards, as is required by the CableLabs spec. http://www.multichannel.com/article/133169-CableLabs_Certifies_First_Wid...
