On Page 2, administer the following:
■ The Number of Digits From PMS field should be left blank, and the
Digit to Insert/Delete field may need to be administered. If the
room numbers use a combination of 3- and 4-digit or 4- and 5-digit
extension numbers, you must enter the leading digit that must be inserted
when sent from the PMS to the switch and that must be deleted when sent
from the switch to the PMS.
NOTE:
The PMS interface supports 3-, 4-, or 5-digit extensions, but be
aware that prefixed extensions do not send the entire number
across the interface. Only the assigned extension number is
sent. Therefore, you should not use prefixed extensions for
numbers that are also going to use the Insert/Delete Digit
function.
This works as shown in the following example:
— Digit Insertion — If the digits received by the switch are 123, and the
insertion digit is 7, extension 7123 is checked to see if it is a valid
extension. If 7123 is valid, the message is processed for
extension 7123; if extension 7123 is not valid, the switch assumes
that the message is for extension 123 and processes it accordingly.
If both 7123 and 123 are valid, the message will only be processed
for extension 7123. Numbering conflicts such as this should be
avoided when possible.
— Digit Deletion — The switch checks the extension number before
the number is sent to the PMS. If the extension number contains the
maximum number of digits translated for a leading digit, and the
leading digit matches the administered Insert/Delete digit, the digit is
deleted before sending the extension to the PMS.
For example, if the Insert/Delete digit is 7, and extensions 712
and 7123 are valid on the switch, 712 will be sent as 712;
however, 7123 is sent as 123. This example presumes that there
are no 5-digit extensions starting with 7 on the switch.
■ The PMS Sends Prefix field indicates whether the PMS sends a prefix
digit to the switch as part of the room numbering plan.
NOTE:
If the PMS Sends Prefix field is set to n, and the Number
of Digits from PMS field is blank, the switch will not
support an extension that starts with 0.
