Motorola Intros RX48 Decoupled Upstream Module for its BSR 64000 I-CMTS

By Nathesh, TMCnet Contributor

Motorola has unveiled the RX48 Upstream Module for its BSR 64000 Integrated Cable Modem Termination System (I-CMTS) solution to help cable operators economically address the growing subscriber demand for higher average and peak upstream bandwidth.

According to a company press release, the BSR 64000 is a proven, high-density, standards-based and fully redundant CMTS/intelligent edge router that allows operators to rapidly introduce differentiated data, voice and multimedia services. It will also aid operators in reducing their cost per downstream channel, resulting in highly cost-effective delivery of advanced services to their subscribers.

The Motorola (News - Alert) BSR 64000 I-CMTS solution, with the new RX48 decoupled upstream module, offers nearly 1.5 Gbps of upstream capacity per module. Motorola had previously released the Decoupled Downstream TX32 module which offers major flexibility for operators so that they can cost effectively scale downstream bandwidth to deliver ultra-broadband service. The upstream-only module is said to be the ‘sister’ card of the TX32 decoupled downstream module.

The combination of these two high-density decoupled modules, along with the simplicity of the integrated design of the BSR 64000, will provide flexibility and scalability for operators. Motorola has claimed that the combined solution will help cable operators save up to 60 percent capital savings over traditional upstream and downstream modules and achieve energy efficiency with a per channel power reduction of 81 percent over previous modules.

Cable operators can also combine the upload-only module with S-CDMA to increase average data rates through higher order modulation, or implement DOCSIS 3.0 upstream channel bonding to achieve up to 150 Mbps of peak upstream bandwidth.

The RX48 is another one of Motorola’s innovative hybrid-fiber coax products which can enable cable operators to rapidly grow their upstream service offering and provide a long-term platform to support evolving IP video services. In addition to the targeting of new commercial services, Motorola also helps operators harness the full potential of the upstream spectrum and enables greater speeds and capacity to existing DOCSIS 1.x and 2.0 environments and offering even richer media experiences to tomorrow's DOCSIS 3.0 connected subscribers.

Recently Motorola helped Vinaphone launch Vietnam’s first 3G service -- and IVR provider Voxeo (News - Alert) bought Motorola’s VoiceXML (News - Alert) browser technology.
