Extension number group(SYS_1) is used for setting the range of extension number and assistant, dialing the extension number outside the range
will be announced “Identification Failed”.
The group number must be successive.
Program ADM5_[YYYY]_[9000] can be used to set number YYYY as non-registered number; once the caller dials YYYY, it will be announced
“Identification Failed”.
Generally, PABX Extension Numbering Scheme has one type or several types listed below:
Extension number
Program Setting
1 No more than 4 digits
Directly enter the extension number
2
More than 4 digits, but several
numbers ahead are identical; it
shall not exceed 4 digits with the
prefix number excluded.
It shall set the "Area Code SYS_6_0_[ ]" as the prefix number.
The Area Code must be excluded when entering extension number, operator’s number, Number forward,
etc.
3
More than 4 digits, but several
numbers ahead are identical; it
exceeds 4 digits with the prefix
number excluded.
4
More than 4 digits and several
numbers ahead are different.
5
It is the extension number
existing among another linking
line PABX (Link Extension)
Designate the extension number length by prefix number:
Beginning number =
0 0 N N
Ending number.=
0 X Y Z
NN: Prefix number for this group of extension.
X= the extension number length of the group, X=0 means flexible length
Y= pause for 3 seconds after the Y
th
digit
Z= pause for 3 seconds again after the Z
th
digit, Z=0 means Un-supervisory transfer
Z=
＊
means
tone detection in Smart mode

Example 1: Company ABC’s extension numbers go from 100~250 and from 30~39 (when the line is busy or is unanswered, and the caller did not
dial another extension, the call is transferred to assistant’s extension – 100).
Where the extension numbers are less than 4 digits, the program setting is as follows:
For 01 Group, beginning number 100, ending number 250: SYS_1_01_1_[100], SYS_1_01_2_[250]
For 02 Group, beginning number 30, ending number 39, Assistant extension 100: SYS_1_02_1_[30], SYS_1_02_2_[39],
SYS_1_02_3_[100]
Example 2: Company ACC’s extension numbers go from 611000~615999, and the Link Extension numbers go from 721000~728999. The number
for the operator is 9 during working hours, and 611000 during closing hours. The program settings are as follows:
611000 ~ 615999 has two identical number ahead, set the Area Code as 61
：
SYS_6_0_[61]
After excluding the Area Code from 611000 ~ 615999, set beginning number 1000 and ending number 5999 for 01 Group
：
SYS_1_01_1_[1000]
，
SYS_1_01_2_[5999]
The Operator number during Working Hours is 9. Because it is single digit, no need to exclude the Area Code, set: ADM_4_1_[9]
The Operator number during closing hours is 611000. After excluding the Area Code, set: ADM_4_5_[1000]
For extension number 721000 ~ 728999, the prefix number is 72, length is 6 digits, CPT detection is initiated after the 6
th
digit
with 3 seconds delay, set: SYS_1_02_1_[0072]
,
SYS_1_02_2_[0606]
720000 ~ 720999 are unused numbers, set prefix number 720 as non-registered number: ADM_5_[720]_[9000]
729000 ~ 729999 are unused numbers, set prefix number 729 as non-registered number: ADM_5_[729]_[9000]
