Patent ID: 6996643

Claim:
In a multi-service platform system, a method of transfer speed negotiation comprising: an initiator VME module communicating a negotiation code to a responder VME module using a two edge source synchronous protocol; if the responder VME module recognizes the negotiation code, the responder VME module communicating to the initiator VME module a negotiation ready signal; the initiator VME module sending a training pattern at a transfer speed to the responder VME module; the responder VME module setting to the transfer speed; if an echo pattern received from the responder VME module corresponds to the training pattern, the initiator VME module sending the training pattern at an incrementally higher transfer speed to the responder VME module; if the echo pattern received from the responder VME module fails to correspond to the training pattern, de-incrementing the transfer speed to a negotiated transfer speed; and setting the negotiated transfer speed between the initiator VME module and the responder VME module.
