Patent ID: 8401023

Claim:
A device comprising: a processor to: receive, from an ingress asynchronous transfer mode (ATM) edge switch, an input extracted from an input ATM set up message, the message for establishing, via an ATM network, a communication between a calling party external to the ATM network and a called party associated with the ATM network, process the input to obtain processed input, determine, based on the processed input, an egress ATM edge switch, of a plurality of ATM edge switches in the ATM network, for the communication between the calling party and the called party, determine a first ATM address for customer premises equipment (CPE) associated with the called party and a second ATM address for the egress ATM edge switch, the processor, when determining the first ATM address, being further to: identify a private address associated with the CPE; and perform private address translation on the private address to identify the first ATM address, and send, to another device, an output identifying the first ATM address and the second ATM address, the output enabling the other device to generate an output ATM setup message that includes: a first parameter storing the first ATM address, and a second parameter storing the second ATM address.
