Multi-port Eos Mapper (RC6400)
RC6400 is a highly integrated EOS device that provides for mapping of 4 Ethernet ports into SDH transport payloads. Complying with ITU-T standards, RC6400 adopts GFP-F encapsulation, low-order virtual concatenation (VCAT) and link capacity adjust scheme (LCAS). The device can communicate with products from other manufactures adopting the same standards.
