  Carrier system - Wikipedia, the free encyclopedia
In telecommunication, a carrier system (loosely, a synonym with carrier) is a multichannel telecommunications system in which a number of individual circuits (data, voice, or combination thereof) are multiplexed for transmission between nodes of a network.
In carrier systems, many different forms of multiplexing may be used, such as time-division multiplexing and frequency-division multiplexing.
Multiple layers of multiplexing may ultimately be performed upon a given input signal; i.e., the output resulting from one stage of modulation may in turn be modulated.

 Modular vehicular carrier system - Patent 5460304
This invention relates to vehicular-mounted carrier components, and more specifically, relates to a modular or interchangeable system of carrier components to be mounted on the rear of a vehicle or on a storage rack remote from the vehicle.
The improved cargo carrier system is easily installed secured and removed by the owner with the capability of being permanently secured in place by means of a lock mechanism, and is conveniently stored by piece in the vehicle or as a system on a rack in a remote location.
The invention also envisions a carrier system tier attachment to a receiver hitch of a vehicle comprising a collection of modular components adapted to be selectively interconnected together including a pair of articulated, deflectable support assemblies, a horizontal platform, a closed container, a bike rack and a ski rack.

 T-carrier - Wikipedia, the free encyclopedia
The basic unit of the T-carrier system is the DS0, which has a transmission rate of 64 kbit/s, and is commonly used for one voice circuit.
Originally the T1 format carried 24 pulse-code modulated, time-division multiplexed speech signals each encoded in 64 kbit/s streams, leaving 8 kbit/s of framing information which facilitates the synchronization and demultiplexing at the receiver.
Technically a DS1 is the data carried on a T1 circuit, and likewise for a DS3 and a T3, but the terms are almost always used interchangeably.

 Dispatch and receive terminal for a pneumatic carrier system - Patent 4189260
The system tube 13 is connected with end wall 27 of the terminal housing 11, and extends from terminal 10 to another terminal (not shown) remote therefrom for transmitting the carrier 15 between those two terminals.
The carrier sensor switch 42 is positioned at that end of the terminal housing 11 remote from the system tube port 39 for sensing receipt of the carrier 15 in the terminal housing.
As the carrier 15 is being preliminarily pushed back into the pusher tube, the air tight integrity of the pusher housing 17 is maintained through the relative sealing relation of the pusher flap's side walls 52, 53 and bottom wall 54 with the pusher flap port 50 defined in the common end wall 28.

 t-carrier system - BlueRider.com
The basic unit of the T-carrier system is the DS0, which has a transmission rate of 64 Kbps, and is commonly used for one voice circuit.
Originally the 1.544 megabit per second T1 format carried 24 pulse-code modulated, time-division multiplexed speech signals each encoded in 64 kilobit per second streams, leaving 8 kilobits per second of framing information which facilitates the synchronisation and demultiplexing at the receiver.
The T-carrier system uses in-band signaling or bit-robbing, resulting in lower transmission rates than the E-carrier system.

The T-carrier system, introduced by the Bell System in the U.S. in the 1960s, was the first successful system that supported digitized voice transmission.
The T-carrier system is entirely digital, using pulse code modulation (PCM) and time-division multiplexing (TDM).
The system uses four wires and provides duplex capability (two wires for receiving and two for sending at the same time).

 E-Carrier System   (Site not responding. Last check: 2007-10-21)
The E1 signal format carries data at a rate of 2.048 million bits per second and can carry 32 channels of 64 Kbps* each.
E1 carries at a somewhat higher data rate than T-1 (which carries 1.544 million bits per second) because, unlike T-1, it does not do bit-robbing and all eight bits per channel are used to code the signal.
E2 (E-2) is a line that carries four multiplexed E1 signals with a data rate of 8.448 million bits per second.

 Images of Carrier packaged air conditioning system
This system has been converted from R500 (Careen 7) to R22, by changing the expansion valves and increasing the pulley size on the open belt drive compressor to slow it down to accommodate the heavier R22.
This system only had a set of screen strainers (top image round objects near the expansion valves), not very good for removing pieces of torn up compressor from years gone by.
Instead of the water being pushed through the system it is arranged so the weight of the water from the cooling tower on the roof is pushing the water through the condensers instead the the pump doing the work.

 E-CARRIER SYSTEM - Definition   (Site not responding. Last check: 2007-10-21)
The basic unit of the E-carrier system is the DS0, which has a transmission rate of 64 Kbps, and is commonly used for one voice circuit.
E2, E3, E4, and E5 circuits carry multiple E1 channels multiplexed, resulting in transmission rates of up to 565.148 Mbps.
The E-carrier system is similar to, and compatible with, the T-carrier system used in North America, but has higher capacity since it uses out-of-band signaling in contrast to the in-band signaling or bit-robbing used in the T-system.

Minimizing co-channel interference is a goal in any cellular system, since it allows better service for a given cell size, or the use of smaller cells, thus increasing the overall capacity of the system.
The GSM system, and its sibling systems operating at 1.8 GHz (called DCS1800) and 1.9 GHz (called GSM1900 or PCS1900, and operating in North America), are a first approach at a true personal communication system.
GSM is also the first system to make extensive use of the Intelligent Networking concept, in in which services like 800 numbers are concentrated and handled from a few centralized service centers, instead of being distributed over every switch in the country.

Anti-Newton Ring carriers are perfect for use in all cold-light or diffusion light enlargers but should not be used in a condenser enlarging system.
Negatives and masks can be easily and quickly placed in, and removed from, the carrier under safelights or even in total darkness without fumbling, speeding up printing time with masks considerably and far reducing the danger of breaking the glass carrier or damaging the original negative.
The glass carrier is made with a "hinged" float glass, eliminating the possibility of dropping the float glass when replacing negatives or masks.
