Abstract
An Optical Network Terminal (ONT) has a fixed number of voice ports. A system employing an example embodiment of the invention increases the number of voice ports without changing hardware in the ONT by employing an Analog Terminal Adaptor (ATA) expander and configuring the ATA expander through use of a Session Initiation Protocol (SIP) and other network resources already available in a network with which the ONT is associated. The ATA expander is configured to be compatible with the ONT and, thus the ONT can increase voice services without hardware changes to support growing demands by customers for access to voice services via increasing number of Customer Premises Equipment (CPE).
