Vendors Transport Tech to Frisco

San Francisco— New transport technology and product updates are expected to lead the list of vendor announcements at the National Show here this week.

BigBand Networks Inc. is slated to introduce its new BRD210 (Broadband Real-Time Decoder) chassis built for gigabit-Ethernet decoding, as well as the new GFM103 card for the company’s broadband multimedia router. BigBand is eyeing the digital simulcast market for both products.

The BRD210 was developed with Ktech Telecommunications Inc., BigBand said. It receives 1 Gbps of Moving Picture Experts Group content over Internet Protocol via a module, and can perform decoding for up to 40 analog video outputs with single audio, 20 with dual audio, or any combination in between.

The GFM cards occupy one slot in existing BigBand BMRs. Each card can receive 1 Gbps of content and decode up to 48 channels in one BMR1200 chassis.

SEP SIGNALS

RGB Networks is scheduled to debut its simulcast edge processor (SEP), designed for cable operators implementing digital simulcast architectures. The SEP will enable operators to receive multiple MPEG-2 video streams over IP, decode, modulate and upconvert them, before delivering the streams directly to subscribers as National Television Systems Committee (NTSC) analog video at the edge of the network.

RGB president and CEO Adam Tom said SEP allows operators to convert and carry all signals in digital to the network’s edge, eliminating the bandwidth drain of transporting a dual analog/digital programming lineup, as well as the cost of separate transmission and video processing equipment.

Fujitsu Network Communications Inc. is adding a wavelength selective switch-based optical core to its Flashwave 7500 reconfigurable optical add/drop multiplexer (ROADM) product line.

“It’s a new optical switch fabric,” said Fujitsu market development manager Randy Eisenach. “It allows for larger ring sizes and larger nodes per ring. It allows optical hubbing to happen.”

Optical hubbing permits MSOs to terminate multiple rings into a single device. “A single device can now terminate traffic from multiple rings,” he said. “You no longer need back-to-back sites,” and it eliminates transponders and dense wave-division multiplexing terminals. “It’s a huge cost savings.”

The WSS technology also enables Fujitsu to replace the optical mux, demux, optical switched cards functions in its Flashwave ROADM devices.

“There is no electrical conversion,” Eisenach said. “It all is integrated into a single module, versus doing it on three different blades,” a configuration that improves efficiencies and lowers optical loss on the system.

Fujitsu has deployed Flashwave ROADM technology in about 20 cable systems across the country, including systems run by Comcast Corp., Bright House Networks, Cox Communications Inc. and Shaw Communications Inc. “It’s the core transport from distribution hubs to headends,” Eisenach said.

VOIP AND VOICEMAIL

In other technology news at the National Show, Siemens AG will demonstrate voice-over-IP caller ID and voicemail notification at its booth. The application allows VoIP subscribers to see the name and number of incoming calls on their TV sets prior to the phone ringing. Call logs and voicemail information can also be displayed.

Siemens is teaming with Integra 5 on the application, which combines the Siemens Surpass hiQ 8000 softswitch, Siemens hiG 1200 media gateway with Integra 5’s UniTV quadruple play application server.

ZyXEL Communications Corp. is showcasing its new Prestige 974SW line of residential cable gateway product that integrates a cable modem, router, switch and wireless access point all in one set-top box. ZyXEL said the new product is CableHome 1.1- and Data Over Cable Service Interface Specification 2.0/1.1-certified. It also sports a built-in 802.11g/11b access point with 54 megabits connectivity.

Elsewhere, Tandberg Television has integrated N2 Broadband’s OpenStream digital services platform with the Moxi Media Center.
