Abstract: Terminal devices and methods which enable reliable management access to network terminals located remotely on the premises of the network service receiver are provided. The invention is suitable for systems utilizing high-speed data packets transmitted via one or more high-speed data networks so that a network manager can access terminals via a management communication link to obtain information about the operating environment and conditions of the remote terminal. Using the management connections and circuitry provided by the invention, a manager can instruct a fiber-optic terminal thus enabled to perform operations that enable and support diagnostics and corrections to problems in the network. Network communication terminals can be managed via a special management port which typically connects to a management interface network, comprised of low-speed serial communication links, and operable with many communication protocols, such as IIC, SPI, and MI.

Abstract: Systems, means and methods for reliably transporting Time Domain Multiplexing (TDM) data over one or more Ethernet installations or networks are provided. The present systems, means and methods provide coordinated frequency multipliers and dividers that are adapted and arranged with phase locked loops such that the respective clock functions of data can be recovered to the extent necessary to assure dependable communication of TDM data over one or more Ethernet networks. Advantageously, the original TDM clock frequency is restored.
