Chapter 3 - Configuration

Phone default connect to

You can select the connection state of the phone set to VoIP FXS codec circuit or to the PSTN port when the line is idle. It is set to ‘FXS’ by factory default for normal usage. For one special case, when the caller ID signal from PSTN line comes before the first ring, then you may select the phone set to be connected to PSTN as default and ensure all the caller ID signal pass to the phone set.

When you select the option “Phone default connect to PSTN”, you must make sure your PSTN line is properly connected to the RJ11 jack of the line port and it is working properly. If your PSTN line is not working with proper voltage on line, the phone set will not operate properly.

Dialing plan

A dialing plan gives the unit a map to determine when a complete number has been entered. Dialing plans are expressed using the same syntax as used by MGCP NCS specification. The formal syntax of the dialing plan is described by the following notation:

Digit ::= “0” “1” “2” “3” “4” “5” “6” “7” “8” “9” Timer ::= “T” “t”

Letter ::= Digit Timer “#” “*” “A” “a” “B” “b” “C” “c” “D” “d”

Range ::= “X” “x” --matches any digit “[“ Letters “]” --matches any of the specified letters

Letters::= Subrange Subrange Letters

Subrange::= Letter --matches the specified letter Digit “-” Digit --matches any digit between first and last

Position::= Letter Range

StringElement::= Position --matches any occurrence of the position Position “.” -- matches an arbitrary number of occurrences including 0

String ::= StringElement StringElement String StringList::= String String “” StringList DialPlan::= String “(“ StringList “)”

A dialing plan, according to this syntax, is defined either by a (case insensitive) string or by a list of strings. Regardless of the above syntax a timer is only allowed if it appears in the last position in a string (12T3 is not valid). Each string is an alternate numbering scheme. The unit will process the dialing plan by comparing the current dial string against the dialing plan, if the result is not qualified (partial matches at least one entry) then it will do nothing further. If the result matches or is over-qualified (no further digits could possibly produce a match) then sends out the string and clear the dial string. The Timer T is activated when it is all that is required to produce a match. The period of timer T is 4 seconds. For example a dialing plan of (xxxTxxxxx) will match immediately if 5 digits are entered, it will also match after a 4 second pause when 3 digits are entered.
