Switching structure for implementing a node in a network for transmitting IP-based time multiplex signals with high bit rates, in particular multi-gigabit ethernet

摘要

The structure has Internet protocol based time multiplex signals e.g. an optical multi gigabit Ethernet. The structure has bi-directional west-sided and east sided remote ports, where a west-sided time multiplex signal is received at the west-sided remote-port and a west-sided transmit-time multiplex signal is sent to the west-sided remote port. An east-sided receive-time multiplex signal is received at the east-sided remote-port and an east-sided transmit-time multiplex signal is sent to the east-sided remote-port. Each signal has a frame structure with virtual time slots. Independent claims are also included for the following: (1) channel card for an optical transmission system with a circuit structure (2) structure of a network node for an optical wavelength multiplex transmission network.
