Dial Plan Analysis Table

Last Updated : Oct 29, 2012 |

The Dial Plan Analysis Table is the system’s guide to translating the digits dialed by users. It determines the beginning digits and total length for each type of call that Communication Manager needs to interpret. The Dial Plan Analysis Table and the Dial Plan Parameters screen work together to define the system’s dial plan.

Example command: change dialplan analysis

Call Type

Valid Entry	Usage
aar	Automatic Alternate Routing — Routes calls within a company's own private network. Requires that ARS/ AAR Dialing without FAC is enabled.
ars	Automatic Route Selection — Routes calls that go outside a company over public networks. ARS also routes calls to remote company locations without a private network. Requires that ARS/ AAR Dialing without FAC is enabled.
attd	Attendant — Defines how users call an attendant. If a telephone’s COR restricts the user from originating calls, this user cannot access the attendant using this code. The attendant access code can also be administered by entering an fac or dac.
dac	Dial access code — Using this feature, you can use trunk access codes (TAC) and feature access codes (FAC) in the same range.
enb-ext	Enbloc extension — Defines a block of extensions that must be dialed using a prefix when the caller dials from a keypad. These extensions can be dialed without a prefix if the caller dials enbloc, for example, from a station call log.
ext	Primary extension — Defines extension ranges that can be used on the system. Extension can have a first digit of 0 through 9 and can have up to 10 digits. Extension cannot have the same first digit as a 1-digit ARS or AAR feature access code (FAC).
fac	Feature access code only — Users dial an FAC instead of programming a button.
pext	Prefixed extension — Identifies the call type as an extension. After digit collection, the prefix digit is removed from the string of dialed digits. The remaining digits make up the extension number and are then processed. With a prefixed extension, extensions numbers with any dialed string can be used. The extension length must be specified on the table.
udp	Uniform Dial Plan — Shares a common dial plan among a group of servers.

Dialed String

The digits that Communication Manager analyzes to determine how to process the call. Two Dial Plan entries can use the same Dialed String only if the Dialed String consists of one digit. Longer Dialed Strings must all be unique. A new entry cannot be administered if it causes an existing extension, feature access code, or trunk access code to become inaccessible.


Call Type	Valid Entry	Usage
aar	0 to 9	Dialed String entry can be one to six digits long.
ars	0 to 9	Dialed String entry can be one to six digits long.
attd	0 to 9	Dialed String entry can be one or two digits long.
dac	0 to 9 * #	Dialed String can be one to four characters long. The characters * and # can only be used as a first digit.
enb-ext	0 to 9	Dialed String can be one to ten digits long. The corresponding Total Length can be up to sixteen digits.
ext	0 to 9	Dialed String can be one to ten digits long. The extension cannot have the same first digit as a one-digit ARS or AAR feature access code (FAC). The corresponding Total Length can be up to sixteen digits.
fac	0 to 9 * #	Dialed String can be one to four characters long. The characters * and # can only be used as a first digit. A FAC must have the longest total length for a given dialed string when using mixed numbering. Otherwise, problems might occur when, for example, three-digit FACs and four-digit extensions begin with the same first digit and the FAC is an abbreviated dialing list access code. However, if the entry in the dial plan that defines the FAC is used to define the AAR or ARS access code, then it must have the longest total length in the dial plan.
pext	0 to 9	The prefix is the first digit and an extension number of up to five digits in length. The maximum length of a prefix and extension combination is six digits long. A prefixed extension cannot have the same first digit as a dial access code. A prefixed extension cannot have the same dialed string as the ARS or AAR FAC.
udp	0 to 9	Dialed String can be one to ten digits long. The corresponding Total Length can be up to eighteen digits.

Location

This field displays the location of the telephone that is used to dial the number. For more information about assigning a location and for a list of features that use the location, see Avaya Aura® Communication Manager Feature Description and Implementation.

Valid entry	Usage
1 to 250 or 1 to 2000	If there are matching entries in the location of the telephone, the system displays the matched entry.
all	If there are no matching entries in the location of the telephone, the system displays all.

Percent Full

Valid Entry	Usage
0 to 100	The percentage of system memory resources that have been allocated for the dial plan currently used. For details on the system memory resources, see Avaya Aura® Communication Manager System Capacities Table.

Total Length

The number of digits for this call type. Must be greater than or equal to the number of digits in the Dialed String.

Valid Entry	Usage
1 to 2	attd
1 to 4	dac
1 to 4	fac
2 to 6	pext
1 to 16	enb-ext
1 to 18	udp
