Abstract: A time division multiplexing (TDM) facility is presented for time division multiplexing at least two inter-system channel (ISC) data streams to create a TDM multiplexed data stream. The TDM multiplexed data stream can be forwarded across the network over a single wavelength of a wavelength division multiplexing (WDM) network. The TDM multiplex data stream may be wavelength division multiplexed with one or more other TDM multiplexed data stream. Different protocols are presented for maintaining disparity balance within the ISC data streams depending upon whether a given sequence in one of the data streams is an idle sequence, frame sequence or continuous sequence.

Abstract: A method for negotiating speed between a Fibre Channel (FC) local client and a remote FC client across a DWDM network is provided. A transmission speed of the local FC client at a local ingress transport interface is detected. The data from the local FC client is forwarded along with the detected transmission speed to a remote egress transport interface. The remote egress interface forwards the data at the detected transmission speed to the remote FC client. The present invention eliminates complex speed negotiation state machines that would otherwise be required to make the DWDM transport behave like a virtual wire with respect to the FC ports and to allow the FC clients to negotiate the desired speed directly between themselves.
