Chips cut budget for inverse
multiplexing ATM
A new family of inverse multiplexing ATM devices will find use in systems that process ATM traffic and require external connections over T1/E1 or xDSL links for compatibility with existing networks.

IDT joins Texas in crossbar low-voltage logic
IDT and Texas Instruments have entered a co-operative agreement to become alternate supply sources of 3.3V crossbar low-voltage technology (CBTLV) bus switch devices.
IP coprocessors provide flexible search width
IDT has released its first commercially available Internet protocol coprocessor product portfolio that enables up to OC-768 wire speed to support ever-increasing packet processing requirements.
The new IMA device family offers unique functionality for remote equipment, such as mobile basestations and DSL multiplexers, by allowing the remote configuration of up to eight IMA groups at a far-end unit via the IMA group auto-detect function.
This feature enables the user to configure and start up IMA logic groups at the near-end unit while forcing the far-end's group to follow the same procedure, eliminating the need for local-side configuration and management at remote sites.
In addition, the IMA family offers the most advanced user interface in the industry, simplifying software development, reducing costs and speeding time to market.
The IDT IMA devices, coupled with the company's SuperJet transceivers, allow IDT to provide a complete solution for IMA line-card applications, with the industry's lowest power consumption, chip count and board space.
The new IMA family includes the 16-channel 82V2616 and the 8-channel 82V2608, and is the first extension of the IDT transport family of T1/E1 devices to include ATM multiplexing.
The family's advanced user interface includes an embedded controller that allows configuration and operation through an API abstraction layer, eliminating the need for complex direct register accesses.
The IMA family also provides a link backup feature that automatically adds a backup link when a previously configured link fails.
This feature serves to maintain quality of service (QoS) with the highest priority available link being automatically selected as the bandwidth recovery link.
Finally, the new IMA devices include an advanced cell buffer management feature that reduces latency and increases maximum delay tolerances to support ATM QoS.
