US 2009/0263139 A1 · Method and apparatus for increasing voice service for an optical network terminal (ONT)

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).

Dependent claims

A method of increasing voice service for an ONT, comprising:

requesting an Internet Protocol (IP) address from a Dynamic Host Configuration Protocol (DHCP) server upstream of an Optical Network Terminal (ONT), the IP address corresponding to an address of an Analog Telephony Adapter (ATA) coupled to the ONT on a downstream side of the ONT;
retrieving a configuration profile, for the ATA, conforming to a same Session Initiation Protocol (SIP) messaging protocol as used by the ONT;
retrieving a user configuration profile for at least one user agent in the ATA to enable the at least one user agent to register with a SIP server upstream of the ONT;
and
registering the at least one user agent of the ATA by using the configuration profiles to activate the at least one user agent for SIP service.
