Start-up jumps into ATM mart with aggressive pricing

Send to colleague

Richardson, Texas

Connectware, Inc. last week launched an all-out assault on the emerging Asynchronous Transfer Mode (ATM) market with the rollout of new products priced well below existing ATM offerings.

The start-up, a subsidiary of electrical connector giant AMP, has compiled technology from a variety of sources and fashioned it into a product set that includes chips, network interface cards (NIC), workgroup switches and an enterprise switch.

Prices for Connectware's Cellerity products undercut actual and announced prices for ATM cards and switches from vendors such as Fore Systems, Inc., Newbridge Networks, Inc. and SynOptics Communications, Inc. by 30% to 60% (see graphic).

According to Kent Savage, director of worldwide marketing for Connectware, the company can keep its prices down by basing its products on single chips and by tapping into AMP's extensive manufacturing base.

"A single-chip solution for [packet-to-cell] segmentation and reassembly on both our cards and switches allows us to keep costs down since we're not overpopulating motherboards with expensive silicon," he said. "Utilizing the manufacturing and worldwide distribution channels of AMP allows us to initiate further cost savings."

Connectware's reign as king of slashed prices may be a short one, however, according to Jennifer Pigg, program director at The Yankee Group, a Boston consultancy.

"By the time Connectware delivers product in the first and second quarter next year, it will not be the only company at those price points," she said. "The pricing would be revolutionary if product was out in July, but by next year, more established players will be at the same per-connection costs."


The Cellerity products are based on a custom application-specific integrated circuit chip that uses VLSI Technology, Inc.'s CMOS technology. The Connectware chip contains a segmentation and reassembly en-gine, a Reduced Instruction Set Computing-based microprocessor and a 32-bit direct memory access bus controller.

The chip will reside on Connectware's line of ATM NICs, which will be designed to connect high-end workstations and servers to Connectware ATM switches as well as devices from other vendors.

The NICs initially will come in 100M and 155M bit/sec multimode fiber-based versions for Extended Industry Standard Architecture, TurboChannel, and SBus workstations and servers. Category 5 un-shielded twisted-pair versions will be available in the future.

The company also unveiled the Cellerity ATM Workgroup Hub, a fixed-port ATM switch that will be available in a fiber-based 12-port version and a 16-port model that supports Category 5 unshielded twisted-pair connections. The switches, which will support either 100M or 155M bit/sec ATM interfaces, will provide connectivity among personal computers and servers, as well as to ATM networks.

Users will be able to stack the switches in groups of up to four, providing a maximum of 48 fiber ports or 64 copper ports.

The switch will feature a 4G bit/sec bus that links switch processors powering each port on a single hub or hub stack in a ring configuration.

The aggregate throughput of the ring will remain at 4G bit/sec no matter how large it gets, so a stack of four switches will only provide nonblocking capabilities for as many as 25 ports simultaneously. Each port will have a 150-cell buffer for data and constant bit rate traffic, with additional buffer space available on a different portion of the switch's motherboard.

The hub's data throughput will be expanded to 8G bit/sec in a later release.

Connectware also said it will develop an enterprise-level ATM switch but declined to provide more details.

Beta releases of Cellerity products will be issued by year end, with general availability due in the first and second quarters of 1995.
