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.

Table
