Local dialing with seven-digit number
EXAMPLE:
( [1-8]xx |
9, xxxxxxx
| 9, <:1>[2-9]xxxxxxxxx | 8,
<:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx !
| 9, 011xxxxxx. | 0 | [49]111)
9, xxxxxxx
After a user presses 9, an external dial tone sounds. The user can
enter any seven-digit number, as in a local call.
•
Local dialing with 3-digit area code and a 7-digit local number
EXAMPLE:
( [1-8]xx | 9, xxxxxxx |
9, <:1>[2-9]xxxxxxxxx
| 8,
<:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx !
| 9, 011xxxxxx. | 0 | [49]11 )
9, <:1>[2-9]xxxxxxxxx
This example is useful where a local area code is required.
After a user presses 9, an external dial tone sounds. The user must enter a 10-
digit number that begins with a digit 2 through 9. The system automatically
inserts the 1 prefix before transmitting the number to the carrier.
•
Local dialing with an automatically inserted 3-digit area code
EXAMPLE:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx |
8,
<:1212>xxxxxxx
| 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9,
011xxxxxx. | 0 | [49]11 )
8, <:1212>xxxxxxx
This is example is useful where a local area code is required
by the carrier but the majority of calls go to one area code. After the user
presses 8, an external dial tone sounds. The user can enter any seven-digit
number. The system automatically inserts the 1 prefix and the 212 area code
before transmitting the number to the carrier.
•
U.S. long distance dialing
EXAMPLE:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx |
8, <:1212>xxxxxxx |
9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9,
011xxxxxx. | 0 | [49]11 )
9, 1 [2-9] xxxxxxxxx
After the user presses 9, an external dial tone sounds. The
user can enter any 11-digit number that starts with 1 and is followed by a digit
2 through 9.

Blocked number
EXAMPLE:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx |
8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx |
9, 1 900 xxxxxxx !
|
9, 011xxxxxx. | 0 | [49]11 )
9, 1 900 xxxxxxx !
This digit sequence is useful if you want to prevent users from
dialing numbers that are associated with high tolls or inappropriate content,
such as 1-900 numbers in the U.S.. After the user press 9, an external dial tone
sounds. If the user enters an 11-digit number that starts with the digits 1900,
the call is rejected.
•
U.S. international dialing
EXAMPLE:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx |
8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx
! |
9, 011xxxxxx.
| 0 | [49]11 )
9, 011xxxxxx.
After the user presses 9, an external dial tone sounds. The user can
enter any number that starts with 011, as in an international call from the U.S.
•
Informational numbers
EXAMPLE:
( [1-8]xx | 9, xxxxxxx
|
9, <:1>[2-9]xxxxxxxxx | 8,
<:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx !
|
9, 011xxxxxx.
|
0 | [49]11
)
0 | [49]11
This example includes two digit sequences, separated by the pipe
character. The first sequence allows a user to dial 0 for an operator. The second
sequence allows the user to enter 411 for local information or 911 for
emergency services.

Acceptance and Transmission the Dialed Digits
When a user dials a series of digits, each sequence in the dial plan is tested as a
possible match. The matching sequences form a set of candidate digit sequences.
As more digits are entered by the user, the set of candidates diminishes until only
one or none are valid. When a terminating event occurs, the SPA9000 either
accepts the user-dialed sequence and initiates a call, or else rejects the sequence
as invalid. The user hears the reorder (fast busy) tone if the dialed sequence is
invalid.
The following table explains how terminating events are processed.
Terminating Event
Processing
The dialed digits do not match
any sequence in the dial plan.
The number is rejected.
The dialed digits exactly match
one sequence in the dial plan.
•
If the sequence is allowed by the dial plan, the
number is accepted and is transmitted
according to the dial plan.
•
If the sequence is blocked by the dial plan, the
number is rejected.
A timeout occurs.
The number is rejected if the dialed digits are
not matched to a digit sequence in the dial
plan within the time specified by the
applicable interdigit timer.
•
The Interdigit Long Timer applies when the
dialed digits do not match any digit sequence
in the dial plan. The default value is 10
seconds.
•
The Interdigit Short Timer applies when the
dialed digits match one or more candidate
sequences in the dial plan. The default value is
3 seconds.
The user presses the # key or
the
dial
softkey on the phone
display.
•
If the sequence is complete and is allowed by
the dial plan, the number is accepted and is
transmitted according to the dial plan.
•
If the sequence is incomplete or is blocked by
the dial plan, the number is rejected.

Dial Plan Timer (Off-Hook Timer)
You can think of the Dial Plan Timer as “the off-hook timer.” This timer starts
counting when the phone goes off hook. If no digits are dialed within the specified
number of seconds, the timer expires and the null entry is evaluated. Unless you
have a special dial plan string to allow a null entry, the call is rejected. The default
value is 5.
Syntax for the Dial Plan Timer
SYNTAX:
(P
s
<:
n
> |
dial plan
)
•
s:
The number of seconds; if no number is entered after
P
, the default timer of 5
seconds applies.
•
n:
(optional): The number to transmit automatically when the timer expires; you
can enter an extension number or a DID number. No wildcard characters are
allowed because the number will be transmitted as shown. If you omit the
number substitution, <:n>, then the user hears a reorder (fast busy) tone after
the specified number of seconds.
Examples for the Dial Plan Timer
•
Allow more time for users to start dialing after taking a phone off hook.
EXAMPLE:
(
P9
| (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx
| 9,8,011xx. | 9,8,xx.|[1-8]xx)
P9
After taking a phone off hook, a user has 9 seconds to begin dialing. If no
digits are pressed within 9 seconds, the user hears a reorder (fast busy) tone.
By setting a longer timer, you allow more time for users to enter the digits.
•
Create a hotline for all sequences on the System Dial Plan
EXAMPLE:
(
P9<:23>
| (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-
9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
P9<:23>
After taking the phone off hook, a user has 9 seconds to begin dialing. If
no digits are pressed within 9 seconds, the call is transmitted automatically to
extension 23.
•
Create a hotline on a line button for an extension
EXAMPLE:
( P0 <:1000>)
With the timer set to 0 seconds, the call is transmitted automatically to the
specified extension when the phone goes off hook. Enter this sequence in the
Phone Dial Plan for Ext 2 or higher on a client station.

Interdigit Long Timer (Incomplete Entry Timer)
You can think of this timer as the “incomplete entry” timer. This timer measures the
interval between dialed digits. It applies as long as the dialed digits do not match
any digit sequences in the dial plan. Unless the user enters another digit within the
specified number of seconds, the entry is evaluated as incomplete, and the call is
rejected. The default value is 10 seconds.
NOTE
This section explains how to edit a timer as part of a dial plan. Alternatively, you can
modify the Control Timer that controls the default interdigit timers for all calls. See
“Resetting the Control Timers,” on page 77
.
Syntax for the Interdigit Long Timer
SYNTAX:
L
:s,
(
dial plan
)
•
s:
The number of seconds; if no number is entered after
L:
, the default timer of
5 seconds applies.
•
Note that the timer sequence appears to the left of the initial parenthesis for the
dial plan.
Example for the Interdigit Long Timer
EXAMPLE:
L:15,
(9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx |
9,8,011xx. | 9,8,xx.|[1-8]xx)
L:15,
This dial plan allows the user to pause for up to 15 seconds between digits
before the Interdigit Long Timer expires. This setting is especially helpful to users
such as sales people, who are reading the numbers from business cards and other
printed materials while dialing.
Interdigit Short Timer (Complete Entry Timer)
You can think of this timer as the “complete entry” timer. This timer measures the
interval between dialed digits. It applies when the dialed digits match at least one
digit sequence in the dial plan. Unless the user enters another digit within the
specified number of seconds, the entry is evaluated. If it is valid, the call proceeds.
If it is invalid, the call is rejected. The default value is 3 seconds.
