The document discusses IERU's FTTx solution concept called FTTB, which uses Metro Ethernet technology for primary access and aggregation. Key elements of the solution include the DM2104, DM3000, and DM705 devices. The DM705 acts as an encapsulation node for transporting TDM services over the IP/Ethernet infrastructure. The solution provides flexibility, protection, intelligence, and support for both IP/Ethernet and TDM networks/services. Network management is provided by the DmView NMS.
