Intelligent network and method for providing voice telephony over ATM and private address translation

A device comprising:

• a processor to:
• intercept, from an ingress asynchronous transfer mode (ATM) edge switch, an input ATM setup message to establish, via an ATM network, a communication between a calling party external to the ATM network and a called party associated with the ATM network,
• determine, based on the input ATM setup message, an egress ATM edge switch, the egress ATM edge switch being associated with an ATM address,
• extract, from the input ATM setup message, data related to an ATM address of a called party customer premises equipment (CPE) associated with the called party,
• generate an output ATM setup message that includes:
• a first parameter to store the ATM address of the called party CPE, and
• a second parameter to store the ATM address of the egress ATM edge switch, and
• communicate the output ATM setup message to the ingress ATM edge switch.

A method performed by a network device, the method comprising:

• receiving, from an ingress ATM edge switch, an input extracted from an input asynchronous transfer mode (ATM) setup 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;
• processing the input to obtain processed input;
• determining, based on the processed input, an egress ATM edge switch, of a plurality of egress ATM edge switches in the ATM network, for the communication between the calling party and the called party,
• determining an ATM address of a called party customer premises equipment (CPE) associated with the called party;
• the determining of the ATM address of the called party CPE, further including:
• identifying a private address associated with the called party CPE;
• and
• performing private address translation on the private address to identify the ATM address of the called party CPE;
• determining, based on the processed input, an ATM address of an egress ATM edge switch associated with the communication;
• and
• generating an output used to generate an output ATM setup message that is forwarded to the ingress ATM edge switch, the output ATM setup message including:
• a first parameter to store the ATM address of the called party CPE, and
• a second parameter to store the ATM address of the egress ATM edge switch.
