[Excerpt from an Global AUTOVON Telephone Directory as found in a Fort
|
||
Lauderdale library... this information is likely getting dated with
|
||
technological advance, but should prove to be interesting history.
|
||
Even if all the terms are not self-explained the overall content
|
||
should be of interest to telecom enthusiasts.]
|
||
|
||
|
||
|
||
AUTOmatic VOice Network (AUTOVON)
|
||
|
||
I. BRIEF DESCRIPTION OF THE AUTOVON
|
||
|
||
A. The Global AUTOVON is the principal long-haul, nonsecure, common
|
||
user voice communications network for the Department of Defense (DoD).
|
||
It provides worldwide direct distance dialing station to station service
|
||
through a system of government owned and leased automatic switching and
|
||
transmission facilities.
|
||
|
||
B. At present, the AUTOVON spans the earth from Asia to the Middle East,
|
||
and from Alaska to Panama. The AUTOVON has approximately 18,000 subscribers
|
||
(direct access to the network). The number of users of the network (those
|
||
who must dial an access code or go through an operator to obtain AUTOVON
|
||
service) far exceed the number of subscribers. Calls on the network average
|
||
about 1.1 million attempts daily with an average call length of 3 to 5
|
||
minutes.
|
||
|
||
C. AUTOVON is a major and integral part of the Defense Communications
|
||
System (DCS). It is comprised of all DoD nontactical long-haul
|
||
point-to-point communications facilities and personnel. It is the
|
||
non-secure common user switched voice network of the DCS.
|
||
|
||
D. The AUTOVON's primary mission is to provide rapid, world-wide command
|
||
and control communications for the National Command Authority (NCA)
|
||
and other high priority subscribers. Its secondary mission is to provide
|
||
an acceptable grade of service for operational, intelligence, logistic,
|
||
administrative, and diplomatic users.
|
||
|
||
II. NATIONAL COMMUNICATIONS SYSTEM VOICE PRECEDENCE SYSTEM
|
||
|
||
A. The National Communications System (NCS) voice precedence system,
|
||
established by NCS Memorandum 1-70 dated 14 February 1970, is directed
|
||
for use by all authorized users of the voice communications facilities
|
||
in the DoD. Since the effectiveness of the system depends on the
|
||
cooperation of the people authorized to employ it, users must (1) be
|
||
familiar with the purpose of each precedence category and the type of
|
||
call that is assigned the precedence, and (2) exercise care not to
|
||
request or use a precedence higher than required.
|
||
|
||
B. The NCS voice precedence system does not make provisions for
|
||
conducting test and exercise calls. Those activities or individuals
|
||
authorized or required to conduct such test or exercise calls will
|
||
employ a precedence consistent with the nature of the test or exercise.
|
||
When the originator of the test or exercise call has contacted the called
|
||
party, the call will immediately be identified as a "FLASH, IMMEDIATE, or
|
||
PRIORITY test or exercise."
|
||
|
||
C. Calls of a given precedence will not normally preempt calls of an
|
||
equal precedence. However, calls originated by the President of the
|
||
United States, Secretary of Defense and Joint Chiefs of Staff can
|
||
preempt FLASH calls in progress by application of their FLASH OVERRIDE
|
||
capability. In addition, Commanders of unified and specified commands,
|
||
when declaring either Defense Condition One (DEFCON ONE) or Air Defense
|
||
Emergency, may preempt FLASH calls in progress by application of the
|
||
FLASH OVERRIDE capability.
|
||
|
||
D. The examples listed below should aid the caller in determining what
|
||
precedence to use. These examples are in accordance with the NCS voice
|
||
precedence system, but are not to be used exclusively for determination
|
||
of the precedence of a call. This should be at the discretion of the
|
||
originator of the call.
|
||
|
||
1. FLASH OVERRIDE It should be noted that FLASH OVERRIDE is a capability
|
||
and is not considered a level of precedence. Exercising this capability
|
||
preempts calls in "ALL" levels of precedence. FLASH OVERRIDE calls will be
|
||
handled as fast as humanly possible. The FLASH OVERRIDE capacility is
|
||
available to the following:
|
||
|
||
(a) The President of the United States of America
|
||
|
||
(b) The Secretary of Defense and Joint Chiefs of Staff.
|
||
|
||
(c) Commanders of unified and specified commands declaring either
|
||
Defense Condition One (DEFCON ONE) or Defense Emergency.
|
||
|
||
(d) CINCNORAD when declaring either DEFCON ONE or Air Defence Emergency.
|
||
|
||
2. FLASH Flash calls preempt IMMEDIATE, PRIORITY, and ROUTINE calls and
|
||
will be handled as fast as humanly possible. Listed below are examples
|
||
of FLASH calls:
|
||
|
||
(a) Calls pertaining to command and control of military forces essential
|
||
to defense and retaliation.
|
||
|
||
(b) Critical intelligence essential to National survival.
|
||
|
||
(c) Conduct of diplomatic negotiations critical to arresting or
|
||
limiting hostilities.
|
||
|
||
(d) Dissemination of critical civil alert information essential to
|
||
National survival.
|
||
|
||
(e) Continuity of Federal Government functions essential to National
|
||
survival.
|
||
|
||
(f) Fulfillment of critical United States internal security functions
|
||
essential to National survival.
|
||
|
||
(g) Catastrophic events of National or International significance.
|
||
|
||
C. IMMEDIATE Immediate calls preempt PRIORITY and ROUTINE calls and are
|
||
reserved for communications pertaining to situations which GRAVELY affect
|
||
the security of Natioanl and Allied forces. These calls will be handled
|
||
as fast as possible. Listed below are some exampled of IMMEDIATE calls:
|
||
|
||
(a) Reconstitution of forces in a post attack period.
|
||
|
||
(b) Intelligence essential to National Security.
|
||
|
||
(c) Conduct of diplomatic negotiations to reduce or limit the
|
||
threat of war.
|
||
|
||
(d) Implementation of Federal Government actions essential to
|
||
National survival.
|
||
|
||
(e) Situations which gravely affect the internal security of
|
||
the United States.
|
||
|
||
(f) Civil Defense actions concerning direction of our population
|
||
and their survival.
|
||
|
||
(g) Disaster or events serious enough to have an immediate and
|
||
detrimental effect on the welfare of the population.
|
||
|
||
(h) Vital information having an immediate effect on aircraft,
|
||
spacecraft or missile operations.
|
||
|
||
(i) Distress assistance.
|
||
|
||
3. PRIORITY Priority calls preempt ROUTINE calls and are reserved for
|
||
communications requiring expeditious action by called parties furnishing
|
||
essential information for conducting government operations.
|
||
|
||
4. ROUTINE This precedence applies to official Government communications
|
||
which require rapid transmission by telephonic means but do not require
|
||
preferential handling. A ROUTINE call does not preempt any other call
|
||
and is handled sequentially as placed by the calling party.
|
||
|
||
|
||
III. WHAT CATEGORY OF NETWORK CUSTOMER ARE YOU?
|
||
|
||
A. You are an AUTOVON SUBSCRIBER if you can make a call on your phone
|
||
without going through a local operator ot DO NOT dial a special access
|
||
number. This type of telephone is installed for command & control and
|
||
other specific operational purposes. More technically, any individual,
|
||
post, station or location directly connected to an AUTOVON switching
|
||
center is a subscriber. This means a post switchboard connected to the
|
||
AUTOVON is also considered a subscriber. Most people who make AUTOVON
|
||
telephone calls DO NOT fall into this category. The majority are
|
||
AUTOVON users.
|
||
|
||
B. You are an AUTOVON USER if you dial a special access number before
|
||
you can make an AUTOVON call or if an operator must place the AUTOVON
|
||
call for you. This distinction between user and subscriber is made
|
||
because there are differences in calling capabilities and instructions
|
||
found later in this directory.
|
||
|
||
IV. WHO IS LISTED IN THE GLOBAL AUTOVON DIRECTORY?
|
||
|
||
A. SUBSCRIBERS are usually the only listing in this directory. If you are
|
||
a subscriber and desire to be listed or if you are listed and do not want
|
||
to be listed, forward requests to DCA Code B522 Washington, D.C. 20305-2000.
|
||
|
||
B. USERS are not normally listed in the Global AUTOVON Telephone Directory.
|
||
However, the following are exceptions:
|
||
|
||
1. If a user is served by a switch which has network in/out dial
|
||
(NIOD) and is not manned 24 hours a day, calling parties must have a
|
||
point of contact when the switch is unattended. Attended nonduty hour
|
||
numbers may be listed in addition to the switch number.
|
||
|
||
2. If a user is an installation which has an individual information
|
||
operator number in addition to the assistance operator number, that
|
||
information number will be listed.
|
||
|
||
C. Requests for user listings should be directed in writing to the user's
|
||
serving communications facility for consideration by the Telecommunications
|
||
Certification Office (TCO). Amplifying information on AUTOVON directory
|
||
listings can be found in DCA Circular 310-V55-6.
|
||
|
||
V. GLOBAL AUTOVON TELEPHONE DIRECTORY DISTRIBUTION
|
||
|
||
A. It is not practical to publish a Global AUTOVON Directory and provide a
|
||
listing of all commands, activities and agencies that have the capability
|
||
to access the network. It follows that distributing the directory to all
|
||
commands, activities and agencies with the capability to access the system
|
||
is costly. Yet, the directory needs the widest possible distribution to be
|
||
effective. This problem is recogniized and distribution of the directory is
|
||
made to all subscribers either directly or indirectly via major commands and
|
||
agencies world wide. All users may purchase the directory from the Government
|
||
Printing Office (GPO). If a directory is unavailable, an alternate method to
|
||
obtain AUTOVON numbers is to consult your local operator.
|
||
|
||
B. Publishers of local directories are encouraged to include excerpts
|
||
from this directory and locally tailored AUTOVON number lists in their
|
||
directories.
|
||
|
||
C. If you are on the DCA distribution list for this directory and your
|
||
address is incorrect, notify DCA, Code B522, Washington, DC, 20305-2000,
|
||
using the correction page in this book.
|
||
|
||
VI. NETWORK RECORDINGS AND SIGNAL TONES
|
||
|
||
A. Various tones and recorded announcements tell you about the progress
|
||
or disposition of your call:
|
||
|
||
1. When you hear a DIAL TONE, the network is ready for your call. Dial
|
||
your number.
|
||
|
||
2. When you hear a RINGING TONE, your called number is ringing. Wait for
|
||
your party to answer. On routine calls, you should hear a normal ringing
|
||
tone (10 rings per minute). On calls of higher precedence, you will hear
|
||
a very fast ringing tone (30 rings per minute).
|
||
|
||
3. When you hear a BUSY TONE, your called number is busy. Try again later.
|
||
If you hear the busy tone and your called number is not in use then local
|
||
or network equipment is busy. Sometimes there is an equipment irregularity.
|
||
Try again later.
|
||
|
||
4. When you hear a PREEMPT TONE, your call was cut off by a higher
|
||
precedence call. Hang up. Wait for a moment in case the call is for you.
|
||
If the preempted call requires completion, custom dictates that whomever
|
||
placed the original call should reestablish it.
|
||
|
||
5. When you hear a WARBLE TONE, answer your phone and standby for a
|
||
conference call or instructions.
|
||
|
||
USE OF AUTOVON
|
||
CONSTITUTES CONSENT TO
|
||
COMMUNICATIONS SECURITY MONITORING
|
||
|
||
B. Below are some of the recorded announcements you might hear while
|
||
using the AUTOVON. These announcements should be noted and reported
|
||
according to procedures outlined in para XV Telephone Trouble Reporting,
|
||
if trouble is suspected.
|
||
|
||
1. "Your call cannot be completed as dialed. Please consult your directory
|
||
and call again or ask your operator for assistance. This is a recording
|
||
(pause) SSB number ____."
|
||
|
||
2. "The precedence used is not authorized for your line. Please use an
|
||
authorized precedence or ask your operator for assistance. This is a
|
||
recording (pause) SSB number ____."
|
||
|
||
3. "Equal or higher precedence calls have prevented completion of your
|
||
call or the number you have dialled is not equipped for preemption. This
|
||
is a recording (pause) SSB number ____."
|
||
|
||
4. "AUTOVON service disruption has prevented the completion of your
|
||
call. Please wait 30 minutes and try again. In case of an emergency,
|
||
call your operator. This is a recording (pause) SSB number ____."
|
||
|
||
VII. CONFERENCE CALLS
|
||
|
||
A. Dial one of the following numbers and tell the operator you wish to
|
||
make a conference call:
|
||
|
||
CONUS Alaska OVERSEAS
|
||
1. Subscribers dial 0 0 550-1411
|
||
2. Users dial 0 0 0
|
||
|
||
VIII. CALLS TO COMMERCIAL NUMBERS
|
||
|
||
Official long-distance calls should be placed using a combination of
|
||
AUTOVON and local base switchboard lines where possible. You can use
|
||
this procedure if the called base switchboard is permitted by the
|
||
commander to connect incoming AUTOVON calls to a commercial number and
|
||
the called commercial number is within the toll free radius of the
|
||
switchboard. OFF-NET extensions will not be completed unless adequate
|
||
call supervision is installed.
|
||
|
||
IX. CALL ASSISTANCE
|
||
|
||
AUTOVON Assistance Operators (AAO) are available to assist subscribers
|
||
when needed. If you are having trouble completing a call, dial "0" to
|
||
reach the AAO.
|
||
|
||
X. SUBSCRIBER PROVIDED EQUIPMENT
|
||
|
||
The terminal equipment provided by the subscriber for connection to
|
||
an AUTOVON switching center must meet the technical interface criteria
|
||
outlined in DCA Circular 310-V175-6, System Interface Criteria.
|
||
|
||
XI. NEW OR ADDITIONAL SERVICE
|
||
|
||
In order to obtain a new AUTOVON service or to change the type of service
|
||
you now have, consult DCA Circular 310-130-1, Submission of Telecommunications
|
||
Service Requests.
|
||
|
||
XII. GLOBAL AUTOVON CALLING
|
||
|
||
A. The AUTOVON telephone network provides global telephone service for
|
||
the DCS. Some subscribers can call everywhere while others are limited
|
||
to one particular area or combination of areas. Where you can call depends
|
||
on your mission and whether your telephone line is equipped accordingly.
|
||
If your calling area is limited, you will not be able to dial outside of
|
||
your limit. The directory indicates calling areas and codes. The area code
|
||
need not be dialed for calls within the area. Calls to an area outside
|
||
the boundary require an area code plus the seven digit AUTOVON number.
|
||
If you are transmitting data, alternate area codes are used. Voice and
|
||
Data area codes are listed on the first page of eacg geographical listing.
|
||
(NOTE: All CONUS and Alaska subscribers can make respective inter-area
|
||
calls by following the above procedures.)
|
||
|
||
B. Secure calls via an AUTOSEVOCOM telephone will be made in accordance
|
||
with instructions in the AUTOSEVOCOM Telephone Directory.
|
||
|
||
XIII. CALLING PROCEDURES
|
||
|
||
A. VOICE TELEPHONE CALLS: Listen for the dial tone, depress the appropriate
|
||
precedence button if the call is to be higher than routine, and dial the
|
||
AUTOVON number as outlined above under global AUTOVON calling.
|
||
|
||
B. DATA TELEPHONE CALLS: Data telephones and associated data equipment
|
||
are operated in accordance with local restrictions. If you send data
|
||
via AUTOVON, it is necessary to observe the following restrictions:
|
||
|
||
1. DO NOT:
|
||
(a) transmit more than 18 continuous minutes.
|
||
(b) transmit more than one hour during the busy calling time.
|
||
(c) use a precedence higher than ROUTINE.
|
||
|
||
2. DO:
|
||
(a) use nonbusy hours for data transmission when possible
|
||
(b) dial "11" to properly condition telephone lines for data calls
|
||
(c) ensure that the device is equipped with an automatic disconnect
|
||
to free the telephone circuit after the device becomes inactive
|
||
for one minute.
|
||
|
||
XV. TELEPHONE TROUBLE REPORTING
|
||
|
||
A. Ensure that the AUTOVON number you used is correct. If you dialed the
|
||
number correctly and you are still having trouble, report the problem as
|
||
follows:
|
||
|
||
1. Keep the line connected if you can. Call the AUTOVON trouble desk at
|
||
550-1611 on a different line. (550-1611 will ring at your serving
|
||
AUTOVON switch.) Tell the trouble desk attendant:
|
||
|
||
(a) Your AUTOVON number and location
|
||
(b) Called party AUTOVON number and location
|
||
(c) What the problem was and when it occurred
|
||
(d) Get the attendant's initials then request a call back when
|
||
the trouble is repaired.
|
||
(e) If you hear an announcement, listen until the end; you will hear
|
||
a number (SSB Nr ____). Provide this to the trouble desk. This will
|
||
help trace the source of the trouble.
|
||
|
||
2. If you can not reache the AUTOVON trouble desk, call your local
|
||
repair service or the operator using a local base telephone. Be sure to
|
||
state that you are reporting an AUTOVON trouble.
|
||
|
||
REPAIR ITEMS SUCH AS BROKEN PARTS OR FRAYED CORDS ARE NOT AUTOVON PROBLEMS
|
||
AND SHOULD BE REFERRED TO THE LOCAL REPAIR SERVICE.
|
||
|
||
XVI. UNSATISFACTORY SERVICE REPORTING
|
||
|
||
A. If you are not satisfied with the results when you reported an AUTOVON
|
||
trouble, please inform DCSO Code B522 in writing. Keep in mind that we
|
||
have to give this report to engineers and technicians for resolution, so
|
||
we have to ask for some fairly technical details. If you need help in making
|
||
the report, contact you local telecommunications officer or OIC of the
|
||
station switchboard. The following information is necessary:
|
||
|
||
1. Your station name, unit name, AUTOVON telephone number and whether the
|
||
trouble concerns a telephone or a switchboard.
|
||
|
||
2. The time and date you first noticed the problem, the AUTOVON trouble
|
||
desk you reported it to and whether the problem was solved.
|
||
|
||
3. What kind of problem you had and the impact it had on your mission.
|
||
|
||
B. If you are unhappy with the agency which was supposed to fix the problem,
|
||
tell us exactly what unit it is, when you called them, when they arrived
|
||
and when/if the problem was repaired. Let us know why you think their
|
||
service was unsatisfactory. If this is a repeated problem, inform us
|
||
how many times and whether your comments apply to each occurrence.
|
||
|
||
C. Give us any background on the problem you have including what the
|
||
maintenance technicians say the trouble was. Suggest any changes you
|
||
would like to see. Pinpoint any trends of performance which may result
|
||
in unsatisfactory service.
|
||
|

XVII. GLOBAL AUTOVON CALLING
|
||
|
||
USERS are normally limited to placing ROUTINE calls within a geographic
|
||
area whether they do the dialling or go through an operator. To call
|
||
outside a calling area, dial "0" and ask the switchboard operatore
|
||
for assistance.
|
||
|
||
|
