Telematics International Inc, Fort Lauderdale, Florida yesterday unveiled a new series of programmable backbone switches and network control centres, more than doubling the throughput of its current mid-range products at substantially less per packet. The Series 4000 Programmable Communications Processor line uses the 16MHz Motorola 68020 and offers a dual-processor architecture to provide nodal throughput of 800 packets per second, twice that of the Series 1000. It can also be field-upgraded with a third processor for more than 1,200 packets per second. The faster processor is further boosted by using the 256-byte on-chip cache so that the Series 4000 can access frequently-used instructions without going to main memory. The 4000 can support up to four expander cabinets and a total of 480 soft configurable user ports. It is available now in several variants including the S 4082/4083 network control centres, S-4071 basic backbone switch and S-4025 characterised backbone switch. Prices go from $38,250 to $86,150 and the current Series 1000s can be field-upgraded to the 4000, and again to the top end Series 5000.
