1. A communications apparatus comprising:
- a client interface operable to receive point-to-point protocol (PPP) data;
a protocol module operable to encapsulate the PPP data as a payload of a facsimile page transmission; and
a network interface operable to establish a link with a remote location, to negotiate a facsimile communications session with the remote location, and to communicate the facsimile page transmission to the remote location, the network interface further operable to signal a local offhook indication to the remote location, to receive a remote offhook indication from the remote location, and to communicate voice information with the remote location using the link during the facsimile communications session.

Abstract
A communications apparatus establishes a link with a remote location, negotiates a facsimile communications session with the remote location, encapsulates point-to-point protocol (PPP) data as a facsimile page transmission, and transmits the page to the remote location. The communications apparatus may also receive PPP data encapsulated in a page transmission acknowledgment from the remote location. Moreover, the communications apparatus and the remote location may switch between voice and data communications using facsimile communications protocols.

13. A communications system comprising:
-
a mobile unit operable to establish a link with a serer using a wireless digital network, to negotiate a facsimile communications session with the server, to encapsulate client point-to-point protocol (PPP) data as a payload of a facsimile page transmission, and to communicate the facsimile page transmission to the server; and a server operable to receive the facsimile page transmission, to extract the client PPP data, to encapsulate server PPP data as a payload of a page transmission acknowledgement, and to communicate the acknowledgement to the mobile station; wherein the mobile unit and the server are each operable to signal an offhook indication and communicate voice information using the link during the facsimile communications session. - View Dependent Claims (14)
