Notes:
|
|
|
|
(1) The Rate Quote System is a voice response system used by operators
|
|
to obtain routing information. The system, now being phased out, was
|
|
used as an alternative to calling the Rate and Route operator.
|
|
Operators would key-in required routing information and a synthesized
|
|
voice would respond. Though the RQS is still operational, operators
|
|
now obtain routing information from COMPIS (See note 10).
|
|
|
|
KP+DD+ONPA+NXX+TNPA+NXX+ST to get the "rate step" for:
|
|
|
|
DD = 00 Now
|
|
DD = 01 Day Call (08:00-17:00)
|
|
DD = 02 Evening Call (17:00-23:00)
|
|
DD = 03 Night Call (23:00-08:00)
|
|
|
|
KP+04+? Something with Mexico, unclear.
|
|
|
|
KP+05+NPA+NXX+ST Gives the routing for a BOC inward (See note 9)
|
|
|
|
KP+06+NPA+NXX+ST gives the routing for for an AT&T inward operator
|
|
(See note 9)
|
|
|
|
KP+07+XXXXXXX+ST Reads back the numbers you just typed
|
|
|
|
KP+08+? Something with Enterprise and Zenith numbers, unclear.
|
|
|
|
KP+09+NPA+NXX+ST Gives you the current time for the area and exchange
|
|
just dialed.
|
|
|
|
(2) When a code is marked spare, that means that there is no current
|
|
or planned networkwide usage. It still may be utilized as a
|
|
non-standard POTS exchange for WATS service by local companies.
|
|
|
|
(3) When a code is marked reserved, it means that there may be planned
|
|
networkwide usage.
|
|
|
|
(4) This code is used by an AT&T custom service. It may be thought of
|
|
as acting like a special area code and takes the following dialing
|
|
format: KP+XXX+YYY+YYYY+ST where XXX is the code in question and Y can
|
|
be any number 0-9.
|
|
|
|
(5) All "points not on an NPA" and "Cable Control" function as pseudo
|
|
area codes and are followed by a telephone number.
|
|
|
|
(6) Calls to the IOC are dialled as follows: KP+160+CCC+ST CCC=Country
|
|
Code (i.e. 044 or 144 for the UK).
|
|
|
|
(7) These are special codes used with Equal Access. They are as
|
|
follows:
|
|
|
|
KP+138+PIC+ST then KP+CC+cc+xxxxx+ST
|
|
KP+158+PIC+ST
|
|
|
|
Where PIC is the primary carrier code, CC is the country code and cc
|
|
is city code. xxxxx is subscriber number. We are not sure exactly when
|
|
and where these are used.
|
|
|
|
(8) All four and five digit codes are dialed as follows:
|
|
KP+NPA+XXXX+ST or KP+NPA+XXXXX+ST. Keep in mind that not every code is
|
|
in use in every NPA.
|
|
|
|
(9) The format for an AT&T inward is usually KP+NPA+121+ST -- In some
|
|
small cities there is an extra code used called a Terminating Toll
|
|
Centre (TTC) or sometimes just a city code. If a TTC is used, the
|
|
format is KP+NPA+TTC+121+ST. To get an inward with most BOCs you dial
|
|
KP+NPA+11591+ST but there are some which use a format of
|
|
KP+NPA+TTC+121+ST. To get the inward routing for a particular
|
|
exchange, use the Rate Quote System (RQS).
|
|
|
|
(10) The number for Rate and Route was 800+141+1212 but this was
|
|
discontinued sometime last year (1987) when the TSPS operators got a
|
|
computer terminal called COMPIS. In each there is an inward which acts
|
|
like a Rate and Route operator. In New York it is 716+121.
|
|
|
|
(11) With the advent of Alliance Teleconferencing, use of the
|
|
conference operator dwindled. There are currently four operator
|
|
handling conferences. They are as follows: Atlanta 404+11511,
|
|
Minneapolis 507+11511, New York 212+11511 and Oakland 415+11511.
|
|
800-225-0233 translates to the conference operator closest to you.
|
|
|
|
(12) The Marine Operator is used in calling ships that are close to
|
|
the United States. There is an operator called the "High Seas"
|
|
operator who can be reached by dialing 800-SEA-CALL (800-732-2255).
|
|
The High Seas operator is a service of AT&T, while Marisat is an
|
|
independent company. A High Seas call can go to any ocean for $14.98
|
|
for the first 3 minutes and $4.98 for each additional minute. A
|
|
Marisat only to three oceans and costs $10 a minute.
|
|
|
|
(13) 116X and 116XX are used to verify an AT&T Calling Card number.
|
|
You dial KP+NPA+116XX+ST when you hear a "bong" you dial the calling
|
|
card number. If you use 11611 you enter the number in Touch Tone and
|
|
if you use 11621 you enter the card number in MF using KP and ST.
|
|
|
|
(14) These ISC codes are used to provide alternate routing for
|
|
electro-mechanical switches. Some older electro-mechanical switches,
|
|
for example #5 Crossbar (5XB) cannot outpulse 011+CCC (CCC=Country
|
|
Code) for international dialing. AT&T has set up these special codes
|
|
to handle international calls. A 5XB can dial KP+18X+ST. They would
|
|
then receive a wink (short blast of 2600 Hz) and would proceed to dial
|
|
the country code and number. If you want to make an international call
|
|
you dial KP+(NPA)+18X+ST where the NPA is optional. After the wink
|
|
dial the country code, city code and number. The "," after the city
|
|
name is the switch number if there is more then one 4-ESS in that
|
|
city.
|
|
|
|
(15) The 187 code was assigned to Atlanta until up to the end of
|
|
February 1988. AT&T is in the process in routing the calls to the
|
|
Sherman Oaks Office in California.
|
|
|
|
(16) To make international calls dial KP+011+CCC+ST where CCC is the
|
|
country code; and then dial KP+CC+XXXXXXX+ST where CC is the city code
|
|
and XXXXXXXX is the telephone number.
