These chip sets are fully programmable and field upgradeable eliminating the risk of product obsolescence and accelerating the time-to-market for new network services. The GlobespanVirata® XDSL2™ DSL chip sets are fully interoperable with multi-vendor DSL chip set solutions. This interoperability enables dynamic interworking of multiple vendor DSL solutions with the capability to interoperate with products that conform to ANSI and ETSI DSL standards. GlobespanVirata’s unique hardware platform supports multiple dual-channel applications including SDSL, HDSL2, and SHDSL, using population options for optimization. The XDSL2 DSL chip sets incorporate two DSL bit pumps plus framing into a three-chip solution comprised of a dualchannel digital signal processor (DSP) with built-in framer and two Analog Front Ends each with an Integrated Line Driver (ILD2). The XDSL2 chip sets interface directly with off-the-shelf T1/ E1 transceivers and Nx64 multiplexing, eliminating the need for a separate DSL framer to combine and format the two DSL channels into a stan...
