Texas Instruments Inc and Proteon Inc have jointly developed circuitry and software that enables users to build large-scale, IBM-compatible 16Mbps Token-Ring Networks over unshielded twisted pair: the JitterBuster technology is designed to enable users to build networks up to the 250 node count specified by the IEEE 802.5 standard where the limit on unshielded twisted pair was limited to 100 nodes per ring; the jitter absorber technology reduces the signal distortion or jitter that typically builds in large token nets; the circuitry can be added to an TMS38053-based Token-Ring Network interface card; Texas will announce licensing terms, packaging and availability later on.
