	IBM JRD 49-4/5 \| Challenges of data center thermal management
		The data center consisted of 40 racks of data processing (DP) equipment, with front-to-back cooling, which were placed in rows in an alternating hot aisle/cold aisle arrangement located in the center of the floor with four CRAC units at the perimeter of the 12.1-m-wide by 13.4-m-long room.
		As in [1], the total chilled air provided to the data center by the CRAC units was varied to 80%, 100%, and 120% of the DP rack flow rate, but it was distributed in three configurations to both the cold and hot aisles.
		Since data centers typically require an additional 30% to 50% of the data processing energy for cooling, it may be possible to save a large amount of energy in the thousands of data centers around the world.

		, hardware> (DCE) The devices and connections of a communications network that connect the communication circuit between the data source and destination (the Data Terminal Equipment or DTE).
		DCE and DTE are usually connected by an EIA-232 serial line.
		It is necessary to distinguish these two types of device because their connectors must be wired differently if a "straight-through" cable (pin 1 to pin 1, pin 2 to pin 2 etc.) is to be used.

	Chapter 5 Page 1 - Telecommunications Handbook for Transportation Professionals
		Before discussing actual communication circuit types it is necessary to look at some of the basic elements of circuits, and then understand their use as part of a traffic signal or freeway management system.
		The modem converts the binary one/zero data protocol of a computer (or other data device) to a protocol that can be carried via a specific medium (11).
		The RS232 communication protocol used by the 170 controller would have to be converted to a light wave signal for transmission for transmission via the fiber.

	RS-232 Serial Communication Overview by Quatech
		Typically DTE is defined as the communication source, and DCE is defined as the device that provides a communication channel between two DTE-type devices.
		In order for DCE and DTE devices to communicate with each other, two wires must be used--one for transmission and the other for reception--and both devices must not use the same wire for the same purpose.
		DCD: Data Carrier Detect--Used by a DCE to indicate to the DTE that it has received a carrier signal from the modem and that real data is being transmitted.
