As part of its "Total DSL" initiative, launched in early August in support of its Gateway-On-A-Chip platform, ishoni Networks Inc. has announced interoperability agreements with three leading DSL equipment providers. The Santa Clara, Calif., company has licensed a voice-over-ATM transport specification from CopperCom Inc., and signed support agreements for a VoiceBand signal protocol from JetStream Communications Inc. and a TollVoice voice-over-Internet-Protocol (VoIP) gateway protocol from Tollbridge Technologies Inc.
"We're working with each of these three leading gateway companies to ensure interoperability of our gateway platform, which will provide a better end-to-end solution for customers," said Greg Gum, vice president of business development at ishoni.
"We're being careful to architect a solution that works with any kind of broadband connection," he said. "Over the next 12 months, it's going to be critical to match all the specific modems in the market to the central office to ensure interoperability."
The company is building the integrated access device (IAD) infrastructure for broadband applications, which is what broadband service providers and equipment vendors need to attract customers, according to Anges Imregh, vice president of marketing at Tollbridge.
Ishoni's "Total DSL" initiative is aimed at achieving interoperability between the leading producers of PHY, DSLAM, and VoDSL equipment manufacturers in the market. The company will make its Gateway-On-A-Chip solution compatible with ADSL, SDSL, G.SHDSL, and voice-over-broadband equipment in DSLAMs, voice gateways, and customer-premise equipment.
Founded in May 1998, ishoni has received about $18 million in funding in two rounds of financing from Bessemer Venture Partners, Infinity Capital LLC/Information Technology Ventures, Invesco, and Lucent Venture Partners, among others. In addition to its Santa Clara headquarters, ishoni has a development center in Bangalore, India.
The company introduced the Gateway-On-A-Chip in March and plans to move to production in November.
The chip integrates four 100-MHz MIPS-based 32-bit RISC processor cores, a DSP supporting four to eight voice channels, an encryption engine, a FlexibleWAN engine to support direct interface to DSL modem chips, a segmentation and reassembly (SAR) engine, an Ethernet MAC controller, and USB, PCI, and UTOPIA interfaces.
The solution, also known as ishoni broadband engines (iBE), are offered in four customized versions: the iBED1000, for low-end data only modems; the iBED2000, for high-end modems with data and advanced-networking capabilities; the iBEDV1000, for low-end modems with data and voice requirements; and the iBEDV2000, for high-end modems with data, voice, and encryption requirements.
"We've created what we believe is 80% to 90% of the capability you need in a residential- or small-office-gateway device in a single piece of silicon," Gum said. "As we ensure interoperability, if you're making one of these gateway boxes you can chose any PHY or modem chip you'd like to work with, and then marry them to our chip and provide all the capabilities required for an integrated voice, data, and security solution for integrated access devices."
The company's next step for interoperability agreements will be with DSLAM providers, Gum said.
