Abstract

See full text

A Multiservice Access Concentrator (MAC) is provided that provides fault tolerant permanent voice calls in a voice over packet-data-network system (VOPS). The MAC sets up at least one permanent voice call by coupling a number of nodes in series using a voice-over-packet protocol and a set of primary connection bindings. Furthermore, at least one set of alternate connection bindings are defined for the permanent voice call. At least one preference-based list is generated comprising the sets of alternate connection bindings. Each node operating with the voice-over-packet protocol is capable of determining at least one out-of-service state for the node. A failure of at least one of the series nodes is detected by the node. A reconnection relationship is established between nodes on either side of a node determined to be out of service. The permanent voice call connection is automatically re-established or reconnected using at least one alternate node. The permanent voice call of an embodiment is transmitted over a Frame Relay network in accordance with a standard comprising a Frame Relay Forum FRF.11 Implementation Agreement.
