Entropic Communications and Panasonic, Inc. (NYSE:MC) have announced a product partnership in the development of c.LINK Access Modems to provide high speed broadband access to the home over coaxial cable.


Broadband World Forum, Madrid, Spain and San Diego, CA - October 3, 2005 - Entropic Communications and Panasonic, Inc. (NYSE:MC) announced a product partnership in the development of c.LINK Access Modems to provide high speed broadband access to the home over coaxial cable. The first major deployment is by Jupiter Telecommunications (J:COM), Japan's largest multiple system operator (MSO), with two million subscribers.

J:COM is rolling out its new broadband cable service with speeds up to 100 Mbps.

Panasonic's TZ -CLM100 Receiver and TZ -CLM110 Network Controller modems are based on Entropic's c.LINK™ chipset. The TZ -CLM100 uses Entropic's EN3030 Access chip, and the TZ -CLM110 houses the EN3010 Access Network Controller. While c.LINK for home digital entertainment networks has been available since 2002, this represents the first major deployment in a network access application, making Entropic a complete provider of networked digital entertainment for the LAN and WAN.

J:COM's adoption of the Panasonic/Entropic co -developed TZ -CLM110 Network Controller, allows multiple distribution of cable signals from one access point. A single network controller can connect up to thirty -one unique receivers, allowing multiple dwelling units (MDUs) such as apartments and condominiums to use existing coax wiring for delivery of high -speed, broadband access services.

The TZ -CLM110 Network Controller receives data from the optical fiber ONT and passes it onto the coax network in the MDU, while the TZ -CLM100, receives signals from the coaxial wiring within individual tenant units.

J:COM operates 17 local cable companies throughout Japan serving nearly two million subscribers. J:COM conducted field trials with the Panasonic Network Controller last fall. During these tests, J:COM engineers established the viability of converting fiber -to -the -home (FTTH) content and sending it to multiple coax outlets in MDUs enabled by c.LINK.

'The combination of Entropic and Panasonic's Network Controllers and receivers allow us to distribute high -speed Internet using familiar, pre -installed coax wiring,' said J:COM vice president of engineering and technical operations, Kanji Kotake. "Now we can offer new services to existing and potential subscribers."

"Panasonic's TZ -CLM110 Network Controller is the interface between the optical fiber network termination (ONT) and the coax infrastructure in the MDU while the TZ -CLM100 is the client modem connected to the existing coaxial wiring within individual tenant units," said John Graham, VP of marketing at Entropic. "These products bring 'triple -play' services - cable television, high -speed Internet, and telephone service - closer to reality."

c.LINK Network Access Chipset

Entropic's c.LINK™ Network Access chipset leverages existing coaxial cable, enabling an easy, cost effective system for service providers to bring high speed data and video networking services to residents within MDUs. There are no new wires or changes to the existing wiring. The technology enables reverse communication through coax splitters and allows selection of broadcast frequencies from 800 MHz to 1500 MHz, with cascading of multiple network controllers to expand unit coverage and coexist with cable, terrestrial and satellite signals.

The c.LINK Network Access chipset is comprised of the EN1010 Coax Network Interface, the EN3030 Access Client and the EN3010 Access Network Controller in a 3.3V/1.8V power supply with 3.3V I/O PCI interface. The EN3010, in combination with the EN1010, is used in devices at the building point -of -entry providing more than 100 Mbps of broadband data to up to 31 units from a single network controller.

The EN3030 is also used in combination with the EN1010 in customer premise equipment (CPEs), such as a, gateway or router. SNMP support, rate adaptation, system upstream and downstream management and support of IEEE 802.1p priorities, are all standard. Network security consists of both hardware DES encryption and network coordinator access control nodes.
