Patent ID: 7864789

Claim:
A signaling method for a telecommunication system comprising a platform connected over a synchronous network using a GFP encapsulation scheme to a provider device having a first Ethernet interface with a customer device, said platform being arranged for exchanging tagged frames including a virtual LAN identifier (VID) with a service unit over a second Ethernet interface, the method comprising the following steps: detecting an error condition at a GFP port of the platform; retrieving a correspondence between said GFP port and a VID ; and forwarding a deregistration message including said VID to the service unit ; wherein the error condition is detected at a GFP port of the platform responsive to reception of at least one GFP error message from the provider device; and establishing an uplink end-to-end connection by sending a first registration message including said VID to the service unit upon expiry of a timer started responsive to reception at the GFP port of said at least one GFP error message, said expiry occurring while no further GFP error message has been received at said GFP port from the timer start.
