The Lucent Stinger product family initially included thehigh capacity Stinger FS and the smallerprofile Stinger LS. The Stinger FS has aport density of up to 672 xDSL ports. This capacity yields over 2000 xDSL ports when3 shelves are placed in a standard central office rack, providing the highest port density of any DSLAM on the market. There are two versions of the Stinger LS to accommodate 19 and 23 inch central office racks.
Model 1 offers a port density up to 240xDSL ports and Model 2 up to 336 xDSL ports. Both LS models are also offered in anenvironmentally hardened version, calledthe Stinger RT, designed for use in outdoor environments such as curb side cabinets.
These Lucent Stinger units could support a mix of OC-3/STM-1, DS3/E3and T1/E1 IMA trunk interfaces.
Later on, Lucent introduced the Lucent Stinger FS+ in the market which increased the capacity of the Lucent DSL offer by50%. By relying on 72-port modules, it supports 1,008subscribers per chassis, up to 3,024 per rack, in both ANSIand ETSI installations.By providingthe bandwidth needed to support increased subscriberdensities, the Stinger FS+ more than quadruples itsprevious performance levels to real data forwardingthroughput up to 7.2 Gbps. With Gigabit Ethernet and OC-12 bandwidth to the backbone and enhancements such asIP multicast, the new Stinger solution enables operatorsand ISP’s to offerhigh-speed video and data delivery over DSL.
