Arrive’s SONET/SDH CodeChip product line offers a family of highly integrated SONET/SDH Framer/Mapper products that can be used in Linear or Ring topology SONET/SDH networks. They can support typical transport configurations, including PDH-over-SONET/SDH, Ethernet/FE/GE-over-PDH, Ethernet/FE/GE-over-PDH over-SONET/SDH, and Ethernet/FE/GE-over-SONET/SDH.

The SONET/SDH CodeChip family begins with a series of core features based on the proven AT4848 ASIC and other proven devices. From these, each specific design is tailored to a customer’s specifications.
