from other extensions connected to the unit through an FXS port, and only FXS ports can be configured for this function.
If a customized numbering scheme is desired, entries for each number can be added to the table.
The Current Routing Table displays the following fields for each entry:
Index – index number I/F – interface type
Logical Port – logical port numbers Number – the phone number to be routed TRNC – the truncation length *
Pre – the prefix number * Post – the postfix number *
Valid – the validity of the table entry *
*The items marked with an asterisk are intended for special circumstances. The items should be left unchanged in typical applications.
Logical Port Numbering
The difference between physical and logical port numbering is that, in logical port numbering, the FXS and FXO ports are counted separately, and the count starts from zero instead of one. So the first FXS port will be FXS 0, and the first FXO port will be called FXO 0.
A Physical and Logical Port Number Table (Appendix D in this Guide) has been provided for you to write down the positions of your FXS and FXO ports so that they are available for future reference.
