Description
Suppression bit: the system flags the call to the Central Office
(CO) so that the name and number is not sent to the person you
call.
Service code: VSC digits are dialed out before the called number
to activate ONN at the central office. These codes are supplied by
your service provider for the lines. Refer to
(North American systems)" on page
code, so do not require specific configuration.
Description
Supports target lines in markets which use Overlap receiving
signaling on the BRI trunks. Overlap receiving must be
configured for each BRI loop.
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.
