Local number length 0-10
ONN blocking state Suppression bit,
Service code
Send Name Display Y, N
(Type: QSIG trunks
only)
Description
Set the local number length for loops to interfaces that receive overlap
rather than enbloc digits. This number is the total length of the called party
number received. This number is used to calculate the number of leading
digits that need to be removed by the system.
Note: This parameter appears only when Overlap receiving is set to Y.
Example:
Public received number = 4502303
Target line received numbers = 303
Local number length = 7
Public received number length = 3
Thus the first four digits are deleted by the system.
Set the Outgoing Name and Number (ONN) Blocking. When the user
presses FEATURE 819, on a per-call basis, the system flags the call to the
Central Office (CO) so that the name and number is not sent to the person
being called.
Set this field to Suppression bit to use the Calling Line Information
Restriction (CLIR) service.
For ETSI ISDN lines that do not use the ETSI CLIR service, the Central
Office (CO) may use a Service code to provide blocking service. In that
case, this field must be set to Service code. The service provider code
must then be programmed into the ONN blocking section. Refer to
"Configuring ONN blocking service codes" on page
Programming note: Ensure that all telephones that have this feature
available are assigned valid OLI numbers. Refer to
on page 406.
If you want the OLI of the calling telephone to display on the called
telephone, with this type of trunk, set this field to Y.
If this field is set to N, no outgoing call display is sent. Refer also to
