Flexible Feature Codes
Flexible Feature Codes containing an asterisk (*) or an octothorpe (#) will
always be allowed by OCB. Therefore, FFCs which can be used to make a
call should be entirely numeric if barring of them is required.
Some FFCs are equivalent to Special Prefix functions and these is subject
to barring based on the equivalent Special Prefix codes, even if the FFC is
entirely numeric.
Last Number Redial
Barred DNs is stored by Last Number Redial (LNR). DNs re-dialed using
LNR are checked against the active OCB level.
OCB Flexible Feature Codes are not stored as the last number dialed.
Network Alternate Route Selection (NARS)/Basic Alternate Route
Selection (BARS)
Calls made through NARS or BARS that result in local termination may
not be barred based on the full dialed digits. They is barred based on the
resulting local digits. Calls to a Local Steering Code will use the full dialed
digits, as well as the resulting termination. Calls to the Home Location
Code (HLOC) is barred based on the AC1 and HLOC, and then barred
separately based on the local DN. Other local terminations include calls to
an Numbering Plan Area (NPA) or Home Numbering Plan Area (HNPA)
that use Supplemental Digit Restriction and Recognition to recognize a
Local Direct Inward Dialing (DID) number, and calls using a Route List Block
which terminate using the LTER option.
New Flexible Code Restriction
Outgoing Call Barring uses New Flexible Code Restriction (NFCR) trees to
define the digit sequences that are not allowed for each level of barring.
However, OCB analyses all dialed digits, whereas NFCR only analyses
digits outpulsed on trunks. This means that the same tree will not normally
be usable for both features, unless only Coordinated Dialing Plan trunk calls
are to be blocked for both features and no digit manipulation is done.
Outpulsing of Asterisks and Octothorpes
The NFCR trees used for Outgoing Call Barring are allowed to contain
asterisks and octothorpes when the Outpulsing of Asterisk and Octothorpe
(OPAO) package 104 is equipped. These special digits will only be used for
processing dialed digits on routes with OPAO allowed.
Remote Call Forward
Activation of CFW to a barred DN by Remote Call Forward is permitted,
since the user has had to dial the Station Control Password, which could
also have been used to deactivate OCB.
