Operation With A Parent Pabx; To Programme Pabx Access Digits - BT Versatility V16 Owner's Manual

Operation with a parent PABX

You can connect the BT Versatility to a parent PABX via its Line interfaces.
You can programme any of the eleven Outgoing Groups to work with a parent PABX.
When programming the Outgoing Groups as PABX groups, PABX access digits and the
number of digits in a PABX extension number are entered. The PABX access digits are
the digits that must be dialled to select an exchange Line in the parent PABX. (You can
have a maximum of two PABX access digits).
If you wish to make an external call via the parent PABX, you must select a line
connected to the PABX, placing the access digit(s) before the external number you
require. If you wish to make a call to a parent PABX extension, you must select a Line
connected to the PABX and dial the extension number without any access digit(s).
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, that is, an extension prevented from making external
calls will be also prevented from making external calls through the parent PABX.
Both external numbers and PABX extension numbers may be entered into Personal and
System Speed Dial lists. When a speed dial number is selected for dialling, the system
checks whether the number is a PABX extension by checking the number of digits
against the programmed extension number length. If it is a PABX extension the system
selects a PABX Group and if a Line is free dials the digits. If the selected number is an
external number, the system attempts to select an exchange Line. If one is available, it
dials the number without inserting the access digits. If an exchange Line is not available
a free PABX Line is selected and the access digits are automatically inserted.
If Redial is activated the number is redialled on the same group on which the original
call was made.
