1. Local Call (7 digit)
In most areas, local calls are a 7 digit number, which consist of the 7 right-most digits. The Area Code
(the first NXX) is not used.
Hybrex Communications, telephone number is Area Code 561, the Office Code is 747 and our Subscriber
Number is 4466.
Another telephone user within our local dialing area will dial only 747-4466. This is the only dialing string
the local telephone company will accept.
Example:
If I receive a call from the business next door, my caller ID unit will display 561-555-3489. In
order to redial the call, I must dial 555 + 3489. It will be necessary to program system to
recognize that the 561-555 area code and office code combination is local and will disregard the
area code and dial only the office code and subscriber number (555+3489).
In order to make the TD-824i redial this number properly, set
Program 84-01-01 with a value of
561
(Home Area Code). You will also set
Program 86-555 to a value of 0
. This tells the
system when it sees the area code of 561 AND the office code of 555, the redial function will be
to dial only the office code and subscriber number (555+3489).
2. Local Toll (7 digit)
Some localities (a good example is the state of Maine, in the northeastern U.S.) allows 7 digit dialing to
the entire state, even though some calls are billed at toll rates. So a caller ID report from a telephone in
the state of Maine to another telephone in the state of Maine will show
207 234 5678
. However if a caller
ID machine is going to provide redial capabilities, it must remove the area code 207 and dial only
234
5678.
Example:
If I receive a call from the company across the state, my caller ID unit will display 207-234-
5678. In order to redial the call, I must dial 234 + 5678.
In this example, set
Program 84-01-01 with a value of 207
(Home Area Code). You will also
set
Program 86-200 through 86-999 to a value of 0
. With this programming, whenever a
number begins with the area code 207 the redial function will only dial the office code and
subscriber number (7 digits).
Note:
The default database already has 86-200 through 86-999 set to 0.
3. Local Call (10 digit)
Some larger cities in the United States have exhausted an entire area code. Miami, Florida is a good
example of this. Instead of separating portions of Miami and assigning unique area codes to different
geographic regions, the telco has instead introduced an ”overlay” area code. There are two area codes
that cover the same geographic area. In this situation, all local calls must dial
NXX-NXX-XXXX
for all
local calls.
Example:
I receive a call from the business next door. My caller ID unit displays 305-471-9091. To
redial the number I dial 305 + 471 + 9091.
This situation requires that you set
Program 85-01-01
to a value of 305. The TD-824i supports up
to a total of 5 “overlay” codes, so other overlay codes will be programmed on 85-02-01, 85-03-01,
85-04-01 and 85-05-01.
When calls are received from within your overlay area, the TD-824i will redial the call using all 10 digits
received from the telephone company, Area Code – Office Code – Subscriber Number as listed in the
example paragraph, above.
4. Local Toll (1 + 7 digit)
Within a large part of North America area codes cover a large amount of land. In these situations, a call
within your own area code will require that you dial 1 + the rightmost 7 digits of the telephone number. So
