OPERATION WITH A PARENT PBX

You can connect the Mitel 3000 to a parent PBX via its line interfaces.

You can program any of the 11 outgoing groups to work with a parent PBX. When programming the

outgoing groups as PBX groups, PBX access digits and the number of digits in a PBX extension number

are entered. The PBX access digits are the digits that must be dialed to select a CO line in the parent PBX.

(You can have a maximum of two PBX access digits).

If you wish to make an external call via the parent PBX, you must select a line connected to the PBX, and

dial the access digit(s) before the number. If you wish to make a call to a parent PBX extension, you must

select a line connected to the PBX and dial the extension number.

Note: The system will take the access digits into account in deciding whether the extension is restricted

from making the call according to its Class-of-Service. For example, an extension prevented from making

external calls will be also prevented from making external calls through the parent PBX.

Both external numbers and PBX extension numbers can be entered into Personal and System Speed-Dial

Lists. When a speed-dial number is selected for dialing, the system checks whether the number is a PBX

extension by checking the number of digits against the programmed extension number length. If it is a

PBX extension, the system selects a PBX group and, if a line is free dials the digits. If the selected number

is an external number, the system attempts to select a CO line. If one is available, it dials the number

without inserting the access digits. If a CO line is not available a free PBX line is selected and the access

digits are automatically inserted.

If Redial is activated, the number is redialed on the same group on which the original call was made.
