To make use of DID trunks, program "Group-
Trunk Group", Type to DID, and assign the CO
lines to be used for DID by programming the
"Trunk-CO Line", Trunk Group option. Set the
DID Start Arrangement in "Trunk-CO Line" and
the DID Digit Modification Table in "Group-Trunk
Group (2/2)". This table is used to convert the
subscriber numbers sent from the Central Office
into DNs or Floating Directory Numbers (FDN).
The number of "received digits", "digits to be
deleted" and "the digits to insert" are
programmed in the "Special Attended-DID"
screen.

Conditions
A subscriber number received from the Central
Office is converted into a DN or FDN according
to the DID Digit Modification Table setting as
follows.
<Example>
"Special Attended-DID" Table settings
Receive Digit: 4
Delete Digit: 2
Insert Dial No.: 2
Subscriber number received from the Central
Office: 43112
Processing
<1> The "2" in 43112 is ignored since there are
four receive digits. This leaves 4311.
<2> "43" is deleted since there are two delete
digits. This leaves 11. Note that the digits
are deleted from the beginning of the
number.
<3> Inserting Dial No. "2" makes the final
number 211 which serves as the DN or
FDN. Note that digits are inserted before
the beginning of the number.
Reorder tone is sent to the DID caller if the
number of digits received is less than the number
programmed in "Special Attended-DID", Receive
Digit.
The subscriber number received from the Central
Office is converted into a DN or FDN. If it could
not be put through to the incoming call
destination, because the DN or FDN does not
exist or the destination is Out of Service, the call
is sent to the destination specified by the "Group-
Trunk Group", Intercept Routing (Day/Night). If
there is nothing programmed for intercept routing
then the call is sent to Operator 1.*
* If MFC signaling is utilized, reorder tone is sent
to the caller in this case.
When the CO Forward Mode function has been
programmed in "System-Class of Service" for
the DID incoming call destination, forwarding will
not take place, and the call will be put through to
the extension.
