Abstract:
1. A method for connecting a call across an Asynchronous Transfer Mode-Multiprotocol Label Switching (ATM-MPLS) network of network elements as a communication path for the call is being set up, the call comprising an encapsulation mode parameter for which a particular value must be assigned for each MPLS segment of the communication path between adjacent network elements, at least one network element supporting multiple values for the encapsulation mode parameter, the method comprising: receiving at a network element on the communication path an indicator that network elements along the communication path of the call are required to use a predetermined value for the encapsulation mode parameter when susceptibility to clipping is enabled for the call; and establishing a connection to an adjacent network element on the communication path using the predetermined value for the encapsulation mode parameter, prior to setting up a next MPLS segment of the communication path.
