LAS VEGAS -- Lucent Technologies Inc.'s Microelectronics Group today introduced a series of asynchronous transfer mode (ATM) interconnect chips, which it said 10 customers are designing into next-generation systems. One of those is Huawei Technologies, one of China's largest broadband access equipment manufacturers, the company said Networld+Interop here.
The CelXpres series includes a single device with 64 physical layer interconnects, enabling as many as eight times the number of subscribers to receive high-speed asymmetrical digital subscriber line (ADSL) Internet services from a single telephone central-office digital line card.
By using any one of the CelXpres series of Lucent chip products--the T8206, T8207, and T8208--manufacturers of various types of high-speed, telecommunications equipment can shave the time required to deliver products to market by up to one year, while reducing electronics costs. This is similar to the claim Lucent made on Monday for a reference design platform it developed for GPRS mobile handsets (see May 8 story).
Lucent said its chips are versatile enough to be used with various DSL services, including Full Rate and Lite ADSL, symmetrical DSL, high-speed DSL (HDSL and HDSL-2), and very high speed DSL (VDSL).
"These chips remove a critical bottleneck at the line card to allow many more households to get access to many different types of services, including high-speed Internet services," said Dave Romero, strategic marketing manager with the Network Access business unit of Lucent's Microelectronics Group, based in Allentown, Pa.
"In addition, developing a custom-designed interconnect, which is widely done today, can be a costly and resource-intensive development project for our equipment customer," he continued. "By using our chips and available reference information, equipment manufacturers bypass having to design, evaluate and simulate the platform interconnect, thus slashing their time-to-market intervals and electronics costs."
Lucent's family of ATM backplane interconnect devices provide information management and routing, enabling Quality of Service (QoS) features on customer lines, which is a critical capability for voice-over-DSL. CelXpres chips function as bridge technologies between a system backplane and Lucent's eight-channel, full-rate WildWire ADSL central office chip set announced last week (see May 3 story). The CelXpres chips manage intra-system traffic to multiple WildWire devices on a line card.
Lucent's T8207 chip can support up to 32 ADSL lines on a single telephone equipment line card--four times more than are common today. The T8208 will support twice this number of lines-64-with single latency, or 32 with dual latency support for voice and data over the same connection. Packing more bandwidth into the same amount of space lowers overall electronics costs.
When used independently, Lucent's chips support bus data rates of up to 2 gigabits per second; when used in pairs the data rates can run twice as fast. To enable Internet service and telephony providers to maximize revenues, the chip also offers the flexibility to easily prioritize voice, data, and video services to customers.
"Service providers prize the ability to prioritize and differentiate the services they provide their customers to enhance revenues," added Romero. "These new chips give them that flexibility that directly bolsters their bottom lines."
The T8206 chip is currently shipping in sample quantities. The T8207 will be sampling in June; production quantities are scheduled to start shipping by July for both chips. The T8208 samples will be generally available in this year's fourth quarter. The T8206, T8207, and T8208 are priced at $48, $53, and $61, respectively, in quantities of 10,000.
