Abstract
A method and apparatus for transmitting voice, voiceband data and phone signaling is described. Analog voice, voiceband data and phone signaling are converted into their corresponding digitized version. The digital voice, digitized voiceband data, and digitized phone signaling may be transported as AAL2 packets via an LAN that follows an LAN protocol that supports levels of transmission priority. The LAN protocol may be, for example, HomePNA. The packets may be formatted in a manner similar to other networking protocols for transmitting digitized voice, digitized voiceband data and digitized phone signaling, such as AAL2. The use of AAL2 packets instead of voice over IP packets and techniques allows use of simpler less costly components and a straightforward interworking at the residential gateway device connected to the WAN via DSL using the emerging loop emulation service. Furthermore, the use of a priority-based network provides an alternative to the use of a logically separate network dedicated to transmitting digitized voice, digitized voiceband data and digitized phone signaling, and hence the higher costs associated with the logically separate network.
