                      | Copper |   Copper lines, which have been used for Plain Old Telephone
                    Service (POTS) and ISDN, also serve as conduits for digital
                    subscriber line (DSL)
                    technologies. The most prevalent DSL technologies are asymmetric
                    DSL (ADSL), with quad spectrum
                    speeds up to 50Mbps downstream and 5.5Mbps upstream, and
                    recently standardized VDSL2, with speeds up to 100Mbps symmetric.
                    Speeds can vary depending on the distance between the telecom
                    provider’s central office (CO)
                    and the subscriber’s
                  modem or router. (CPE).

 Central
                    Office (CO) ProductsOur Maximus™ and Arion™ families of DSL products
                    are used in central office communications equipment that
                    aggregate and process data traffic from a substantial number
                    of individual telephone lines for transmission through a
                    data network. Our high performance, tightly-integrated infrastructure
                    chipsets offer high port density coupled with low power consumption.
 Customer
                    Premises Equipment (CPE) ProductsOur Palladia™ family of products is used in various
                    types of customer premises equipment that process data signals
                    between regular telephone lines and a computer. Our high
                    performance DSL CPE chipsets enable CPE equipment manufacturers
                    to produce devices with high data throughput, rich feature
                    functionality, small form factor and low power consumption.
