Digits Modification Procedures
The System modifies the DID number according to the following three parameters.
1.
Digit to receive DID
The number of digits effective in the received DID number.
2.
Digits to delete
The number of digits to be deleted from the beginning of the digits processed in Step 1.
3.
Number to be added
The dials to be inserted at the beginning of the digits processed in Step 2.
[Example]
Digit to receive DID: 4 (digits)
Digits to delete: 1 (digit)
Number to be added: 2
The System modifies the received DID number "4311" into "2311" as follows:
Processed in Step 2: 4311 311
The first digit "4" was deleted. This results in "311."
Processed in Step 3: 311 2311
The digit "2" was added to the beginning of "311." This results in "2311."
DID Dial Registration
The System converts the modified number into the destination DN or FDN according to this
table.
[Example] The System searches for the number "2311" in the table. When matching is found,
the call rings the corresponding extension or floating station.
Conditions
• What if the dialing digits received is not enough to decide the call destination?
If the number of digits received is less than the number which is programmed in "Digit to
receive DID," reorder tone is sent to the caller, or the call is redirected to the IRNA
destination (IRNA feature). This is determined by System Programming.
• What if the call destination is busy?
If the destination of a DID call is in busy status, the caller may hear a busy tone or the call
is redirected to the IRNA destination or the call waits until the destination becomes idle.
This is determined by System Programming <Section 2.8 System Option, "18. Destination
Busy - DID" in the Programming Guide>.
• Hardware Requirements
To utilize this feature, a BRI card (KX-TD50288) or a PRI23 card (KX-TD50290) is
required.
• The tenant number and VPS trunk group number can be assigned in the DID table so that
the system is shared with tenants on a DID No. basis. It is programmable whether to enable
DID / MDN No.
