Access Arrangement
|
|
~~~~~~~~~~~~~~~~~~
|
|
Another name for a protective connecting arrangement. Access ar-
|
|
rangement is normally used in reference to the interconnection
|
|
of customer-provided data modems or automatic calling units in
|
|
which data access arrangement (DAA) service includes the provision
|
|
of a DAA with appropriate loop conditioning (including adjustments
|
|
for loop loss) to meet data requirements. Got that?

~~~ ...also See Abbreviation for CB Achievement Test.
|
|
|
|
Actual Work Time (AWT)
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
The average time an operator requires to handle a call. This
|
|
corresponds to the expected value (mean value) of the holding
|
|
time distribution used in the ol' Erlang C model. Bob the Cow
|
|
enjoys the Erlang C model. Very much, in fact. Moo.
|
|
|
|
Adaptive Transversal Equalizer
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
A transversal filter that automatically adjusts its characteristics
|
|
to compensate for linear distortion. Adaptive equalizers are par-
|
|
ticularly important in data modems where their use has permitted
|
|
voiceband data rates to be increased from about 3000 bits/per/sec
|
|
to about 10,000 bps. This ain't no run-of-the-mill transversal
|
|
filter, let me assure you.
|
|
|
|
Address
|
|
~~~~~~~
|
|
(1) Where fascist pig postal people deliver their letters.
|
|
(2) A sequence of #'s that identifies the phone to which a call
|
|
is directed. An address is usually 7 to 10 digits, depending
|
|
on whether the destination is in- or outside the NPA where
|
|
the call originated. Also called a Destination Code (or,
|
|
far more technically, a p-h-o-n-e n-u-m-b-e-r).
|
|
(3) Digital info. (a combo. of bits) that identifies a location
|
|
in a storage device or equipment unit (ie, a computer, etc.).
|
|
|
|
Address Signals
|
|
~~~~~~~~~~~~~~~
|
|
Signals used to convey call destination info., such as telephone
|
|
station codes, c.o. codes, and area codes. Some forms of address
|
|
signals are called pulses; dial pulses, MF pulses, etc.
|
|
|
|
Administration
|
|
~~~~~~~~~~~~~~
|
|
In operating companies, dial or network administration is a number
|
|
of related functions with the aim of ensuring the overall provision
|
|
of service by a switching system. This includes assignment of lines
|
|
and trunks to switching terminals, collection of traffic data,
|
|
analysis of troubles and customer gripes, and requests for
|
|
additions and modifications to switching systems.

Alerting (Alerting Signal)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
This is a signal sent to a customer, PBX, or switch to indicate an
|
|
incoming call. A common form is the signal that rings a bell in
|
|
your average telephone, usually arousing the customer from
|
|
sleep, the shower, the climax of Pudenda-Around-the-Globe, etc.
|
|
|
|
All-Number Calling (ANC)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
The system of telephone numbering that uses all numbers and
|
|
replaces the 2-letter plus 5-number (2L + 5N) numbering plan.
|
|
ANC offers more usable combo's of numbers than the old 2L+5N
|
|
numbering plan and has just about become nationally standard.
|
|
|
|
Alternate Routing
|
|
~~~~~~~~~~~~~~~~~
|
|
A way to selectively distribute traffic over a number of routes
|
|
which ultimately lead to the same destination. Sometimes called
|
|
Call Detouring.
|
|
|
|
AM
|
|
~~
|
|
Amplitude Modulation; that is, when an EM wave is transmitted
|
|
(such as radio waves), that wave is given an "identity" by
|
|
modulating its amplitude (i.e., its 'heigth', in very rough
|
|
terms).

|
|
|
Analog Facility Terminal (AFT)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
A voice-frequency facility terminal that performs signaling and
|
|
transmission functions and includes analog channel banks. It
|
|
interfaces between an analog carrier system and a switching system,
|
|
a metallic facility, a digital facility terminal, or another
|
|
analog facility terminal.
|
|
|
|
Analog Signal
|
|
~~~~~~~~~~~~~
|
|
A signal that varies in a continuous manner, such as voice or
|
|
music. An analog signal may be contrasted with a digital signal
|
|
which represents only distinct states. The signal put out by
|
|
a data set has both analog and digital characteristics.

Answer Delay
|
|
~~~~~~~~~~~~
|
|
Just what you think it is: the time from the beginning of a phone's
|
|
ringing to the moment the receiving end answers. Answer delay
|
|
patterns are one of the traffic indicators your friendly non-ess
|
|
CO looks at when trying to nab boxers (since boxing, from the CO's
|
|
frame of reference, is just a longer-than-normal, unsuccessful
|
|
answer delay).
|
|
|
|

|
|
order of arrival and are routed to positions in the order of
|
|
their availability for handling the call.
|
|
|
|
Automatic Intercept Center (AIC)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
A centrally located set of equipment that is a part of an Automatic
|
|
Intercept System and provides arrangements, having stored program
|
|
control, whereby the caller is automatically advised, by means of
|
|
either recorded or electronically assembled announcements, of the
|
|
situation that prevents completion of connection to the
|
|
called number.
|
|
|
|
Automatic Intercept System (AIS)

|
and processing of info. relating to calls for billing purposes.
|
|
|
|
Automatic Number Identification (ANI)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
The automatic identification of a calling station, usually for
|
|
automatic message accounting (and thus, in the end, for billing).
|
|
ANI, to you neophytes, is one of the scourges of ess. It's the
|
|
magic that makes using Bell Calling Cards unwise...et cetera.
|
|
|
|
Automatic Ringdown
|
|
~~~~~~~~~~~~~~~~~~
|
|
A technique for supervision alerting on a nondial trunk in which
|
|
the application of a 2-second burst of ringing at the originating
|
|
end results in a supervisory signal at the terminating manual
|
|
PBX. See Ringdown.
|
|
|
|
Automatic Voice Network (AUTOVON)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
A private voiceband nerwork serving the Dept. of Defense. AUTOVON
|
|
uses automatic switching and handles both voice and data traffic.
|
|
It is worldwide; the continental U.S. portion is known as CONUS

AWT See Actual Work Time
|
|
~~~ ~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Balance
|
|
~~~~~~~
|
|
(1) To distribute traffic over the line terminals at a CO as
|
|
uniformly as possible. Without load balancing, a portion of
|
|
the switching equipment may become overloaded even though the
|
|
total capacity of the system has not been exceeded.
|
|
(2) To adjust the impedance of circuits and balance networks to
|
|
achieve specified return loss objectives at junctions of 2-
|
|
wire and 4-wire circuits.
|
|
|
|
Balance Network
|
|
~~~~~~~~~~~~~~~
|
|
An adjustable impedance used to terminate one port of a hybrid
|
|
such that the hybrid characteristics approach the ideal when used
|
|
to provide 2 to 4-wire conversion.
|
|
|
|
Baseband
|
|
~~~~~~~~
|
|
The frequency band occupied by one or more info. signals that
|
|
either modulate a carrier or are transmitted at baseband freq.
|
|
over a suitable medium.
|
|
|
|
Baud
|
|
~~~~
|
|
A unit of digital signaling rate. The signaling rate in bauds is
|
|
equal to the reciprocal of the length in seconds of the signal
|
|
element when all signal elements have equal length. If sig.
|
|
elements are not of equal length, as in "stop-start" character
|
|
asynchronous operation, the signaling rate in bauds is expressed
|
|
as the reciprocal of the length of the shortest signal element.
|
|
The information rate in bits per second may be greater than the
|
|
baud rate because one signal element can represent more than one
|
|
bit. So, okay?

Bell System Practice
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
A document in a comprehensive series prepared to spread detailed
|
|
technical info. and operating methods within the Bell System.
|
|
Certain series of BSPs cover manufacturing, installation,
|
|
computer crime/prevention (ha!), and equipment performance
|
|
requirements; these things are mainly of interest to Western
|
|
Electric. Other series are instructions for engineering, operation,
|
|
and maintenance, and repair of the telephone 'plant'; these are
|
|
mainly of interest to operating companies. Other BSPs are prepared
|
|
for the instruction and training of telephone company personnel
|
|
(the Being a Bitch BSP for TSOs, etc.).
|
|
Most BSPs are edited by Western Electric. Bell Labs prepares
|
|
certain BSPs and is responsible for the accuracy of technical
|
|
content of all BSPs. AT&T authorizes the preparation and release
|
|
of all Bell System Practices.
|
|

|
(2) Perfect indicative of 'byte'. HAHAHAHA. Ahem.
|
|
(3) A unit of info. One bit of info. is sufficient to specify one
|
|
of two equally likely possibilities.
|
|
|
|
Bits per Second (b/s)
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
Digital info. rate expressed as the number of binary info. units
|
|
transmitted per second. See Symbol. If a channel produces errors,
|
|
the info. rate (as defined by Shannon) will be lower than the
|
|
figure noted above, but this lower figure is rarely used.
|
|
Typically, a data channel is described as having a stated bit rate
|
|
and a stated expected error rate.
|
|
|
|
Blocking
|
|
~~~~~~~~
|
|
The inability of the calling party to be connected to the called
|
|
party because either a) all suitable trunk paths are busy or b)

|
a path between a given inlet and any suitable free outlet of the
|
|
switching network of a switching system is unavailable.
|
|
|
|
Bridged Tap

|
|
in the distribution cable. Above many BSWs will be a warning
|
|
sign, put in place by Mother Bell, to insure the safety of those

in the general public who plan to dig around said wires. Hmm...
|
|
|
|
Business Communications Systems (BCS)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
Systems, such as key telephones, pbx's, automatic call distrib-
|
|
utors, and telephone answering systems, that are used to fill the
|
|
communication needs of business customers and the discerning
|
|
phreak. Because BCS has become a term used by other companies, the
|
|
term is being replaced by Customer Switching Systems (CSS).
|
|
|
|
Business Customer Services (BCS)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
This term refers to a class of services generally used by business
|
|
customers, including pbx service, key tele. service, automatic
|
|
call distribution service, and tele. answering service.
|
|
|
|
Business Information Systems (BIS)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|

|
Business Information System Customer Services-Facility Assignment
|
|
and Control System (BISCUS/FACS)

|
|
regarding requests for service, subsequent changes in service,
|
|
questions relating to billing, questions regarding Bell's
|
|
liability for customers' coronaries caused from billing, and
|

|
|
|
|
Busy Hour
|
|
~~~~~~~~~
|
|
That hour during which the portion of the telephone network in
|
|
question carries the most traffic. Traffic peaks caused by
|
|
holidays or special events are not considered. Switching systems
|
|
and trunk groups are normally sized for the busy hour load.
|
|
|
|
Busy Hour, Bouncing
|
|
~~~~~~~~~~~~~~~~~~~
|
|
The highest load may not occur at the same hour on all days, need-
|
|
less to say. If the highest load is selected for each day without
|
|
regard to the hour in which it occurs, the average of these loads
|
|
is said to occur in the bouncing busy hour. Traffic measurements
|
|
are usually made over the five working days of each week.
|
|
|
|
Busy Hour, Fixed
|
|
~~~~~~~~~~~~~~~~
|
|
(Okay, this is the last busy hour def. Bear with me. This stuff is
|
|
great for social engineering. Really. Anyway, you never know.)
|
|
When the hourly loads are averaged across days for each hour of the
|
|
day, the max. of these averages defines the fixed busy hour, also
|
|
called the time consistent busy hour. Traffic measurements are usu-
|
|
ally made over the five working days of each week.
|
|
|
|
Busy Tone
|
|
~~~~~~~~~
|
|
An audible signal indicating a call can't be completed because
|
|
the called line is busy. The tone is applied 60 times per minute.
|
|
|

|
|
onslaught begins. So watch for Vol. II, coming soon to a bbs
