	Privateline.com: Packet and circuit switching
		TDMA and CDMA in wireless, T-Carrier and SONET in wireline networks, are transmission methods, transport mechanisms that carry information from one point to another across the telephone network.
		These networks rely on telephone lines, of course, but the circuits are so arranged that they retain a permanent connection with their customers.
		Replacing circuit switched switches with packet switches accross the country would be a monumental task, requiring billions of dollars over years and years.

	Thesis (K. Lampert) - Chapter 2
		The gateway is connected to the WAN which typically utilizes a Public-switched Data Network (PSDN) to transfer data.
		The word stream is used in the sense that all user data is treated as two simultaneous streams of incoming and outgoing data.
		Data is transmitted to the IP layer in units known as segments.

	Windows NT: Understanding PPTP (Windows NT 4.0)
		Data sent using this second connection is in the form of IP datagrams that contain PPP packets, referred to as encapsulated PPP packets.
		However, tunneling enables the routing network to transmit the packet to an intermediary computer, such as a PPTP server, that is connected to the both the routing network and the private network.
		Network access servers are built by companies such as 3Com, Ascend, ECI Telematics, and U.S. Robotics, that are members of the PPTP Forum.

	QUALCOMM Press Center - QUALCOMM Ships Integrated Fax and Data Capabilities for CDMA Wireless Network Infrastructure
		Digital fax and circuit-switched data both employ a technique that is highly efficient for large data transfers, as a dedicated connection is maintained for the duration of the data call.
		Packet data offers a direct connection to the Internet in two to three seconds, and requires no "modem training time." Packet data is supported for speeds up to 14.4 kbps, and is expected to be commercially available in QUALCOMM infrastructure in March 1998.
		Because data is handled similarly to voice in the network, CDMA's inherent variable rate transmission capability also applies to data services, allowing the data rate to be determined by the amount of information being sent.
