`
`RADIO PAGIIIO ACCESS: Provides attendant and phone user
`diai access to customer-owned radio paging equipment to selec~
`tively tone-aiert, or voice-page individuals carrying pocket radio
`receivers. The paged party can answer by dialing an answering code
`from a phone within the PBX.
`
`RADIO PAOIIIG ACCESS WITH ANSWER BACK: Aliows
`access to customer-provided paging systems, and provides the
`capability in the PBX to connect the paged party when the former
`answers the radio page by dialing a special code from any PBX.
`
`RADIO WAVE: Electromagnetic waves of frequencies between
`10 KHz and 3MHz, propagated without guide in free space (air).
`
`“DOME: A plastic cover for a microwave antenna. Protects the
`antenna from awful weather.
`
`RAIN A‘I'I'SNIIA'I'IOII: Signal tosses due to absorption are com-
`mon when radio signals encounter a heaviiy moisture laden at-
`mosphere. Generally, the higher the radio frequency, the more at»
`tenuation (is. the more loses). Since microwave signals (for sateilite
`and for land line) are essentially tins of sight, microwave radio is
`very susceptible to signal attenuation due to heavy rain. Modern
`microwave paths are engineered with weather patterns in mind. in
`areas where heavy rainfalls occur, microwave links may be closer
`together or more attention is paid to diverse routing.
`
`RAIN BARREL EFFECT: Signal distortion of a voice telephone
`line caused by the under-attenuated echoes on the return path.
`
`RAM: Random Access Memory. The primary memory in a com-
`puter. it's memory that can be ovenlvritten with new information. The
`“random access" part of its name comes from the fact that the next
`"bit" of information in RAM can be tocated -—- no matter where it
`is —- in an equal amount of time. This means that access to and
`from RAM memory is extraordinarily fast. By ecntrast, other storage
`media -——- like magnetic tape —— have their information stored serial-—
`ly, one bit after another. Therefore you have to search for them. And
`your search time will depend on how far from the bit you’re sear-
`ching for, you are. Floppy disks are faster than magnetic tape,
`because their information is readily at hand, though the readlwrite
`head will have to search for it. Hard disks are even faster because
`there are multiple heads and because the disks spin faster and
`everything moves faster. RAM memory is the fastest of all. The

`
`problem with RAM memory is that it’s'volatile.-:This means when
`power is turned off (or power glitches occur) RAM memory is eras-
`ed .- RAM memory can be protected with rechargeable batteries —
`inst-remember to charge the batteries.
`--

`
`RANDOM ACCESS: Usually refers to computer memory or
`storage. Random Access is the ability to reach any piece of data
`in the memory directly without having to pass by other pieces of
`data. in telephony,
`this means the ability to reach any other
`subscriber through the telco switching network. See SEQUENTIAL
`ACCESS.
`'
`
`unison access madam see RAM.
`
`RANDOM NOISE: interference to tetephone communications
`which occurs at irregular intervals.
`-
`-
`
`RANGE EX'I‘ENDER: A device that increases the length of a local
`loop by boosting battery voltage being sent out from the telephone
`company central office.
`
`EASTER: A pattern of horizontal scanning lines on a TV screen.
`Input data causes the beam of the TV tu be to illuminate the correct
`dots to produce the required characters.
`
`RA'I': A publisher or editor exhibiting unreasonable tyrannical
`tendencies. A condition often aggravated by emigration from English-
`speaking countries south of the equator. '.
`RATE: The price of a particular service or piece of equipment from
`a telephonecompany. Telephone companies don't use the word
`Er“21
`“price.” They "use the word "rate." Nc-one knows why. except
`_
`if they didn’t: cultivate their own jargon. there’d be no job for telecom-
`munications dictionary writers. God forbid!

`
`M“- - AVIIIAGIHG: Telephone companies’ method for
`establishing ’uniform pricing by distance. rather than on the relative
`cost (to them) of the particular route. The theory is that some routes
`are more heavily trafficked, have huge transmission equipments and
`achieve great economies of scale.- Some routes, on the other hand.
`have little traffic, have small transmission equipment. and achieve

`devices called Cypress, Cedar and Juniper and will probably have
`more by the time you read this.
`
`-
`
`IlOl: Return On investment.
`
`ROM: Flead Only Memory. Computer memory which can only be
`read from. New data cannot be entered and the existing data is non-
`volatile. This means it stays there even when power is turned off.
`A ROM is a memory device which is programmed at the factory and
`whose contents thereafter cannot be altered. In contrast is the device
`
`called RAM, whose contents can be altered. See READ ONLY
`MEMORY.
`
`ROOH CUT-OFF: Hotellmctel guest telephones restricted from
`outgoing catls when the guest room is unoccupied.
`
`
`
`ROOM STA'I'IlS AND SELECI'IOH: Provides the capability to
`store and display the occupancy and cleaning status and the type
`number of each guest room. This helps housekeeping management,
`maid locating and room selection. Also, communications between
`the front desk and the housekeeper are speeded up via real-time
`maid activity and checkout audit printouts to indicate which rooms
`need cleaning next. The occupancy status is normally changed by
`the maid or inspector dialing from the room telephone.
`
`ROSE: As in Bodin. The very thoughtful lady who helps us, our
`friends and customers out. We couldn’t survive without Rose. Call
`her and telt her this. 1-212-691-8215.
`
`ROSE, AHNE: A wonderful lady who will get a real kick out of
`seeing her name in this dictionary.
`
`ROTARY DIAL: The circular telephone dial. As it returns to its
`normal position (after being turned) it opens and cioses the elec4
`trical loop sent by the centre! office. Thus it generates pulses for
`each digit dialed. You can hear the "clicks". The number “seven,”
`for example consists of seven “opens and closes,” or seven cticks.
`You can dial on a rotary phone without using the rotary dial. Simply
`depress the switch hook quickly, allowing pauses in between to
`signify that you're about to send a new digit. it’s a good party trick.

`
`RBOC: Regional Bell Operating Company. There are seven RBOCs
`each of which own two or more 8003 (Bell Operating Companies).
`The RBOCs were carved out of the old AT&TIBeIl System by Judge
`Harold Greene when he signed off on the divestiture of the Bell
`operating companies from AT&T at the end of 1984. There is nothing
`magical about seven — nor the grouping of 8003 into RBOCS —
`except the Judge wanted to keep them all roughly the same size.
`
`RCC: Radio Common Carrier.
`
`RCL: FieCaLl.
`

`
`RBI: Recail Diat Tone.
`
`ROY: Ready.
`
`REA: Fiural Electrification Administration. A federal agency which
`makes loans to extend telephone service into rural areas. The REA
`has been one of the most successful federal government programs
`ever.
`
`READ: To glean information from a storage device, like a floppy
`disk. The opposite of READ is to WRITE. That’s when you put in-
`formation onto that storage device. Some storage devices can only
`be READ, but not written to. On a floppy disk that’s calied being
`“WRITE PROTECTED.” See also WORM. which stands for Write
`Once, Read Many.
`-
`
`READER: 1. A device which converts information into a format that
`can be recognized by a machine as input. 2. A device which inter-
`prets coded data in the process of transferring that data from one
`coded state of storage to another.
`
`READ ONLY MEMORY: ROM. A memory device which is pro-
`grammed at the factory and whose contents thereafter cannot be
`aitered -— by a power breakdown, or being written to. or anything
`else. ROM memory is also random-access, which means access-
`ing its information is very fast. See also RAM.
`
`READ-WRITE CYCLE: Time of reading and writing data onto a '
`memory device. See READ.
`
`REAL TIME: A voice telephone conversation is conducted in Real
`Time. That is, there is no perceived delay in the transmission of the
