Feature History
Contents
This feature module describes the Cisco BTS 10200 Softswitch support for the outgoing call barring (OCB) feature. This feature was introduced in Release 3.2, and enhanced in Release 4.4.1. The OCB feature allows an individual subscriber or business group administrator to restrict certain types of outgoing calls. Once the OCB feature is provisioned and activated on a calling line, the OCB restrictions are transparently invoked on all outgoing calls.
OCB Highlights (Release 3.2)
The following list highlights some of the major functions and behaviors for the OCB feature in Release 3.2:
•
K-values (call-barring levels) are K=1 (all calls), K=2 (domestic long distance and international), and K=3 (international). These values are automatically enabled for the handset user when the OCB feature is provisioned by the service provider.
•
The private identification number (PIN) and PIN length are provisioned by the service provider. They cannot be provisioned by the user via the handset, and cannot be changed by the user.
•
If a user forgets the original password, the service provider can, with proper authorization, reset the password. The service provider (after proper authorization) can provision a new password and inform the subscriber.
•
Only one K-value can be active at any time on a specific subscriber line.
•
If the user deactivates OCB via the handset, the system deactivates OCB without checking the K-value the user enters.
•
If the user attempts to reactivate OCB to the same K-value that is currently active, the system treats the attempt as a new attempt, and provides the same success announcement as for the previous activation. If the user attempts to activate OCB to a different K-value than is currently-activated, the system plays the appropriate announcement.
OCB Highlights (Release 4.4.1)
Release 4.4.1 introduces extensions to the OCB feature. It is important to understand that the Release 4.4.1 extensions to OCB are additions to the initial Release 3.2 OCB feature. If you provision a Release 4.4.1 system using Release 3.2 OCB provisioning steps, the OCB feature will, by default, operate exactly as it did when initially introduced in Release 3.2.
The following list describes the OCB enhancements introduced with Release 4.4.1:
•
The range of K-values (call-barring levels) is 1 through 9, and the service provider can provision each of the 9 values for specific call types.
•
K-values can be mapped to call-types at the POP or at the office level. If K-values are not mapped at the POP level, the software checks to see if they are mapped at the office level. If K-values are not provisioned at either the POP or office level, OCB defaults to the hard-coded mapping of the three K-values as in Release 3.2. K-value mapping need not be configured per subscriber.
•
Only one K-value can be active on a specific subscriber line.
•
The service provider can provision three deactivation options for the handset user, including the option to deactivate only if the user enters a currently-active K-value.
•
The PIN length is provisioned by the service provider and cannot be provisioned by the user via the handset, and cannot be changed by the user. The initial PIN setup can be performed either by the service provider, or can be provisioned for the user to set up using the handset. However, the initial PIN cannot be changed by the handset user.
•
If a user forgets the original password, the service provider (after proper authorization) can reset the password.
How To Use This Document
If you provision a Release 4.4.1 system using Release 3.2 OCB provisioning steps, the OCB feature will, by default, operate exactly as it did when initially introduced in Release 3.2.
•
For the Release 3.2 description, provisioning, and behavior, see the "OCB for Release 3.2" section.
•
To use one or more of the enhanced OCB features for Release 4.4.1, see the "OCB Enhancements for Release 4.4.1" section.
OCB for Release 3.2
The outgoing call barring feature allows an individual subscriber or business group administrator to restrict certain types of outgoing calls. Once the OCB feature is provisioned and activated on a calling line, the OCB restrictions are transparently invoked on all outgoing calls.
Note
The class of service (COS) feature is an optional functionality (subset) of OCB. The service provider can provision the COS feature by itself, without the OCB feature. The details are discussed later in this section.
OCB Subscription and Provisioning (Release 3.2)
The service provider sets up OCB service at the request of the subscriber. There are a number of service provider provisionable parameters that affect the behavior of the feature on the subscriber line:
•
Vertical service code (VSC)—ASCII strings that the user must enter to access OCB activation, deactivation, and interrogation options. The recommended values are *54*, #54* and *#54# as used in the examples below. However, VSCs are not preprovisioned in the system. The service provider can provision these values with any unique ASCII string up to five characters long.
•
Private identification number (PIN)—A digit string that the user must enter for authorization to set OCB activation and deactivation options from his or her local phone.
•
PIN length (PIN-LEN)—The number of digits required for a valid PIN.
Note
The PIN and PIN-LEN are provisioned by the service provider. They cannot be provisioned by the user via the handset, and cannot be changed by the user.
•
Allowed activation/deactivation attempts and lockout parameters—Parameters can be provisioned to limit the number of times that a user can enter incorrect data or PIN within a specified time. If the limit is exceeded, the system ignores further activation and deactivation attempts for a provisionable length of time (lockout period).
OCB Activation and User Options (Release 3.2)
OCB activation (OCBA) allows a user to activate OCB and select various call barring options on his or her local phone. The user does this by dialing *54*K-VALUE<PIN># (the trailing # is optional to signify the end of entry). The parameters are defined as follows:
•
*54* is the VSC the user must enter on his or her handset to access the OCBA feature
•
K-VALUE is the parameter that determines the type of outgoing calls to be barred:
–
K-VALUE=1: all outgoing calls barred
–
K-VALUE=2: domestic long distance and international outgoing calls barred
–
K-VALUE=3: international outgoing calls barred
Note
Emergency calls are not barred, regardless of the specified K-value.
•
<PIN> is the assigned private digit string that the user must enter. A success announcement is given on a successful activation, and an error announcement, indicating the type of error, is given if activation is unsuccessful.
Note
The K-VALUE can be changed only when the OCB feature is in the deactivated state.
If a user enters incorrect data or PIN repeatedly in a specified time period, the system can lock out further activation or deactivation attempts, as described in the "OCB Subscription and Provisioning (Release 3.2)" section.
The following user actions are invalid, and the system provides an appropriate error announcement:
•
The user enters a value for K-VALUE that is not 1,2, or 3.
•
The user tries to activate OCB on a fresh system (a system with no initial PIN entry in the SUBSCRIBER-FEATURE-DATA table). In this case, the user receives the error announcement.
OCB Deactivation (Release 3.2)
OCB deactivation (OCBD) allows a user to deactivate all OCB on his or her local phone. The user does this by dialing #54*K-VALUE<PIN>#. The parameters are defined as follows:
•
#54* is the VSC the user must enter on his or her handset to access the OCBD feature
•
K-VALUE must be entered as 1, 2, or 3. However, the actual value is ignored by the system, because OCBD deactivates all call barring.
•
<PIN> is the same as for OCBA.
A success announcement is given on a successful deactivation, and an error announcement, indicating the type of error, is given if deactivation is unsuccessful.
Note
See the Cisco BTS 10200 Softswitch CLI Reference Guide for provisioning details.
If a user enters incorrect data or PIN repeatedly in a specified time period, the system can lock out further activation or deactivation attempts, as described in the "OCB Subscription and Provisioning (Release 3.2)" section.
OCB Interrogation (Release 3.2)
OCB interrogation allows a user to check the level of outgoing call restrictions on his or her local phone. The dial string for OCB Interrogation is *#54#. No PIN is required to use this feature. The system provides an appropriate announcement to the user.
OCB Invocation and Screening (Release 3.2)
For a calling party that is subscribed to OCB, and has activated the feature, the feature is invoked for every call made after the called party digits are dialed. There is no user driven invocation method involved for the feature. Once provisioned for a calling party, and activated on the calling party's line, the invocation is handled automatically by the Cisco BTS 10200 Softswitch.
OCB Lockout Behavior (Release 3.2)
The LOCK-OUT, TO, and FAIL-CNT parameters in the feature table are intended to prevent unauthorized changes or bypassing of OCB screening. If a user repeatedly enters the password or other OCBA/OCBD data incorrectly on the handset, the system can lock the line against both OCBA and OCBD. These tokens control the lockout behavior as described in Table 1.
Tip
Note that there is no service lockout when either the TO or FAIL-CNT token is set to zero.
Table 1 OCB Lockout Behavior
Class of Service Screening via Black and White List (Release 3.2)
Note
The class of service (COS) feature is an optional functionality (subset) of OCB. The service provider can provision the COS feature by itself, without the OCB feature.
The Cisco BTS 10200 Softswitch supports class of service (COS) screening, which is provisioned and assigned by the service provider, and cannot be controlled or deactivated by individual subscribers. The service provider can provision a list of directory numbers (DNs) to appear on a black list or a white list as follows:
•
Black listed calls do not undergo further screening, and all calls on this list are rejected.
•
White listed calls are subject to additional normal OCB restrictions based on call type.
Note
The service provider should provision the desired COS restrictions for all subscribers that have the OCB feature. This ensures that the black and white list restrictions are in effect, even if the user deactivates OCB. COS provisioning steps are provided later in this section.
Separate black and white lists are maintained for local/national calls and international calls.
•
National white/black lists are used to allow/restrict calls to specified destinations within a region or within a local area.
Note
A region is a country or numbering plan area. The national white/black list identifies a set of national destination code (NDCs) and/or exchange codes (ECs) to be allowed or blocked.
Outgoing calls are restricted as follows:
–
No restrictions (default), except that all calls are subject to the additional OCB restrictions
–
National white list—Allows calls within a predefined list, except that all calls are subject to the additional OCB restrictions
–
National black list—All calls within a predefined list are blocked.
Note
National call restrictions do not apply to operator calls. This is true even if national call restriction is provisioned in the cos-restrict table for the calling party.
•
International black/white lists are used to allow/restrict calls made to specific country codes. Outgoing calls are restricted as follows:
–
No international calls allowed—Does not allow any international calls
–
International white list—Allows those calls that have a prefix noted in the white list, except that all calls are subject to the additional OCB restrictions
–
International black list—Does not allow any calls that have a prefix noted in the black list
–
All international calls allowed—No restrictions are applied on any international calls, except that all calls are subject to the additional OCB restrictions
Note
International call restrictions do not apply to operator calls. This is true even if international call restriction is provisioned in the cos-restrict table for the calling party.
The service provider can provision an exception list to override black and white list and OCB screening on certain types of calls. The types of calls on this list can include, for example, emergency calls, toll free calls, and so forth. The applicable types of calls are listed in the NATURE OF DIAL (NOD) table, and the specific exceptions are provisioned in the NOD-RESTRICT-LIST table. These exceptions are applicable at the switch level (all office codes) and cannot be specified for individual subscribers. A provisioning example is included in the "Provision Call Type Screening Exceptions" section.
Feature Interactions (Release 3.2)
Call forwarding—The interaction of OCB and call forwarding features depends upon the sequence in which they are activated:
Note
In this section, "CFx" refers to any of the call forwarding features, CFU, CFB, or CFNA.
•
If OCB is activated prior to CFx activation—OCB screening is performed on each DN the user enters when attempting to activate CFx. Successful CFx activation depends on the existing OCB K-VALUE and the forward-to DN:
–
If the existing OCB K-VALUE is set to block calls to the forward-to DN, then the system does not allow CFx activation. The user receives an error announcement.
–
If the OCB K-VALUE allows calls to this DN, then the CFx activation process continues. Once the CFx activation attempt to a specific DN is accepted by the system, it is applicable permanently regardless of any future OCB K-VALUE changes. That is, future changes to the OCB K-VALUE have no effect on CFx invocation. CFx to this DN can be deactivated by the user in the normal manner (#XX#).
•
If CFx is activated prior to OCB activation—The user can activate the OCB feature, or change the OCB K-VALUE, regardless of the existing CFx feature. However, invocation of OCB depends upon the type of call:
–
User-dialed calls—User-dialed calls can be blocked by OCB (depending on the K-VALUE).
–
Forwarded calls—CFx remains active as originally set up by the user, therefore, calls forwarded by the CFx feature cannot be blocked using OCB screening.
•
COS restriction—The COS feature is an optional functionality (subset) of OCB. To utilize the COS functionality, the service provider must provision individual COS restriction settings for the subscriber line. Table 2 lists additional details about the interaction of COS and OCB.

Release Causes and Announcements (Release 3.2)
Table 3 shows the default mapping of cause codes to announcement IDs and announcement files for the OCB feature.
Note
If an audible announcement file cannot be played on the applicable phone, the system plays a reorder tone.
Provisioning Examples (Release 3.2)
Use CLI commands as shown in the following examples to provision OCB and COS.
Create Entries in the Feature Table for OCB and COS
add feature FNAME=OCBA; tdp1=COLLECTED-INFORMATION; tid1=VERTICAL-SERVICE-CODE; ttype1=R; feature_server_id=FSPTC235; description=OCB activation;
add feature FNAME=OCBD; tdp1=COLLECTED-INFORMATION; tid1=VERTICAL-SERVICE-CODE; ttype1=R; feature_server_id=FSPTC235; description=OCB deactivation;
add feature FNAME=OCBI; tdp1=COLLECTED-INFORMATION; tid1=VERTICAL-SERVICE-CODE; ttype1=R; feature_server_id=FSPTC235; description=OCB interrogation;
add feature FNAME=OCB; tdp1=COLLECTED_INFORMATION; tid1=COS_TRIGGER; TTYPE1=R; FEATURE_SERVER_ID=FSPTC235; TYPE1=PIN-LEN; VALUE1=5; TYPE2=FAIL-CNT; VALUE2=3; TYPE3=TO; VALUE3=20; TYPE4=LOCK-OUT; VALUE4=60; FNAME2=OCBA; FNAME3=OCBD; FNAME4=OCBI; DESCRIPTION=Outgoing Call Barring;
The TYPEn/VALUEn entries are defined as follows (n=1, 2, 3, 4). Note that there is no significance to the order in which these values are assigned, nor the number (1, 2, 3, or 4) assigned in the CLI command:
•
PIN-LEN—The number of digits required for a valid PIN. The range is 1 to 8 (default is 4).
Note
The PIN and PIN-LEN are provisioned by the service provider. They cannot be provisioned by the user via the handset, and cannot be changed by the user.
•
FAIL-CNT (fail count) and TO (timeout, in minutes)—The number of invalid (failed) attempts to activate or deactivate OCB within a specified time period before service is locked out:
–
FAIL-CNT range is 0 to 10.
–
TO range is 0 to 180 minutes. The time span begins with the first OCBA or OCBD failure.
•
LOCK-OUT—The lockout period in minutes during which the OCBA and OCBD features cannot be used. LOCK-OUT range is 0 to 180 minutes. The lockout period begins after the last failed attempt.
Tip
PIN is not provisioned in the feature table. See the "Add Initial Password in Subscriber-Feature-Data Table" section for provisioning of the PIN.
CautionIf you assign a value of zero to the FAIL-CNT, TO, or LOCK-OUT token, this results in special lockout behavior. See the "OCB Lockout Behavior (Release 3.2)" section for details.
add feature fname=COS; tdp1=COLLECTED_INFORMATION; tid1=COS_TRIGGER; ttype1=R; description=Class of service screening; feature_server_id=FSPTC235;
Create Entries in the VSC table for OCB
add vsc fname=OCBA; digit-string=*54*;
add vsc fname=OCBD; digit-string=#54*;
add vsc fname=OCBI; digit-string=*#54#;
Create Entries in the Service Table for OCB and COS
In the service table, add the OCB feature (which automatically includes the COS feature), or add the COS feature only (if no OCB feature is desired). Refer to Table 2 for additional information about COS interaction with OCB.
add service id=1; FNAME1=OCB; (for OCB and option to perform COS screening)
add service id=2; FNAME1=COS; (for COS feature only)
Note
The COS-RESTRICT table default settings do not need to be changed unless COS screening features are desired. The original COS defaults are preset for no COS restriction.
Provision Call Type Screening Exceptions
Provision the call types that are not to be screened by the OCB and COS features. See the nature of dial (NOD) table in the Cisco BTS 10200 Softswitch CLI Reference Guide for a complete list of valid call types.
The following command example ensures that calls to numbers with call-type=EMG will not be screened by the OCB feature.
add nod-restrict-list fname=OCB; nod=EMG;
The following command example ensures that calls to numbers with call-type=POLICE will not be screened by the COS feature.
add nod-restrict-list fname=COS; nod=POLICE;
Create COS Restriction (If Necessary)
Create a COS restriction, if desired.
add cos-restrict id=international; INTL-RESTRICT-TYPE=NO-CC-ALLOWED;
Create Entries in the Subscriber Table and Assign COS Restriction
add subscriber id=china-1; dn=28-8652-8888; privacy=full; cos-restrict-id=international;
Create Entries in the Subscriber Service Profile Table for OCB
add subscriber-service-profile sub-id=china-1; service-id=1;
Add Initial Password in Subscriber-Feature-Data Table
change subscriber-feature-data sub-id=china-1; fname=OCB; type1=PASSWD; value1=12345; type2=K-VALUE; value2=2;
Note
Additional token information for the SUBSCRIBER-FEATURE-DATA table:
The K-VALUE token does not need to be provisioned by the service provider. It is recorded by the system when the subscriber uses the OCBA and OCBD features.
The COUNT and TIME tokens are not provisioned by the service provider. They are system internal.
Centrex Provisioning
Add the feature into the custom-dial-plan table for the Centrex group.
add custom-dial-plan id=cdp1; DIGIT-STRING=*54*; NOD=VSC; FNAME=OCBA; CAT-STRING=11111111111;
add custom-dial-plan ID=cdp1; DIGIT-STRING=#54*; NOD=VSC; FNAME=OCBD; CAT-STRING=11111111111;
add custom-dial-planID=cdp1; DIGIT-STRING=*#54#; NOD=VSC; FNAME=OCBI; CAT-STRING=11111111111;
Billing (Release 3.2)
Billing data is listed in Table 4 through Table 7.
Counters (Release 3.2)
The following counters are maintained for the OCB feature:
•
POTS_OCB_LOCAL_BLOCKED (For every call that is blocked due to K-VALUE being provisioned as `1' for OCB feature, this counter is incremented.)
•
POTS_OCB_NATL_BLOCKED (For every call that is blocked due to K-VALUE being `2' for OCB feature, this global counter is incremented.)
•
POTS_OCB_INTL_BLOCKED (For every call that is blocked due to K-VALUE being `3' for OCB feature, this global counter is incremented.)
•

No events or alarms are generated for the OCB feature.
OCB Enhancements for Release 4.4.1
This section describes the enhancements that have been made to the basic OCB feature that was introduced in Release 3.2. The Release 3.2 information is available in the "OCB for Release 3.2" section.
OCB Subscription and Provisioning (Release 4.4.1)
The service provider sets up OCB service at the request of the subscriber. There are a number of service provider provisionable parameters that affect the behavior of the feature on the subscriber line:
•
Vertical service code (VSC)—ASCII strings that the user must enter to access OCB activation, deactivation, and interrogation options (for example, *54*, #54* and *#54#).
Note
The VSCs used throughout this document are typical values. The service provider can provision these values with the ASCII characters 0-9, *, and #. For a complete list of predefined VSCs, see the Vertical Service Code appendix in the Cisco BTS 10200 Softswitch Command Line Interface Reference Guide.
•
Private identification number (PIN)—A digit string that the user must enter for authorization to set OCB activation and deactivation options from his or her local phone.
Note
Initially, the service provider or the user establishes a PIN for the user. Thereafter, the user cannot modify the PIN.
•
PIN length (PIN-LEN)—The number of digits required for a valid PIN (can be provisioned as 1 to 8 digits).
The PIN and PIN-LEN can be provisioned by the service provider.
The PIN and PIN-LEN cannot be provisioned or changed by a user via the handset if the OCB-PROFILE has not been provisioned at either the point-of-presence (POP) or at the office level. However, if the OCB-PROFILE has been provisioned and the FREE_SELECT_PIN token has been set to Y (Yes), a subscriber can free-select and register a PIN using a handset at activation if a PIN has not already been assigned and registered.
•
Allowed activation/deactivation attempts and lockout parameters—OCB can be provisioned to limit the number of times that a user can enter an incorrect PIN within a specified time. If the limit is exceeded, the system ignores further activation and deactivation attempts for a provisionable length of time (lockout period).
Detailed provisioning steps for these options are provided in the section Configuring (Release 4.4.1).
OCB Activation and User Options (Release 4.4.1)
OCB activation (OCBA) allows a user to activate OCB and select various call barring options on the handset (local phone). A user does this by dialing *54*K-VALUE<PIN># (the trailing # is optional to signify the end of the entry). The parameters are defined as follows:
•
*54* is the VSC the user enters on the handset to access the OCBA feature.
•
K-VALUE is the parameter that determines the type of outgoing calls to be barred. For Release 4.4.1, OCB can enable K-values up to 9 levels.
Note
A K-Value can be mapped to a special mapping table, the OCB-K-Value table.
•
<PIN> is the assigned private digit string that the user must enter. A success announcement is given on a successful activation, and an error announcement, indicating the type of error, is given if activation is unsuccessful.
Note
The K-VALUE can be changed when the OCB feature is active if the subscriber performs another activation and enters a different value for the K-VALUE token. The new K value overwrites the preceding K value.
If a user enters an incorrect PIN repeatedly in a specified time period, the system can lock out further activation or deactivation attempts, as described in the "OCB Subscription and Provisioning (Release 4.4.1)" section.
The following user actions are invalid, and the system provides an appropriate error announcement:
•
The user enters a value for K-VALUE that is not in the range 1 through MAX-K-VALUES (as specified in the OCB-PROFILE table).
If a subscriber attempts an activation and specifies a K-VALUE that is not in the range established by the provisioned MAX-K-VALUE token, the subscriber receives an error announcement. If the MAX-K-VALUES token is not provisioned in the OCB-PROFILE table at either the POP or Cisco BTS 10200 Softswitch, by default, the valid K-VALUE range is 1 through 3.
Note
The POP table is checked first for the MAX-K-VALUE and then the office level (call agent configuration table). If the token is not provisioned in either table, OCB defaults to the behavior established in the initial release of OCB in Cisco BTS 10200 Release 3.2.
•
The user is not provisioned for the OCB feature.
•
The user enters an incorrect PIN.
OCB Deactivation (Release 4.4.1)
The Enhanced OCB feature supports three options for OCB deactivation. An option is specified by provisioning the DEACTIVATION-OPTION token in the OCB-PROFILE table.
NO-K-VALUE Option
To select the NO_K_VALUE deactivation option, the subscriber enters <VSC><PIN> without entering a K-VALUE.
K-VALUE-NO-MATCH Option
The K-VALUE-NO-MATCH deactivation option enables a user to deactivate all OCB on the handset. The user does this by dialing #54*K-VALUE<PIN>#. The parameters are defined as follows:
•
#54* is the VSC the user enters on the handset to access the OCBD feature
•
K-VALUE must be entered as a value from 1 through MAX-K-VALUES. However, the actual value is ignored during processing.
•
<PIN> is the same as for OCBA.
Note
If the K-VALUE token is not provisioned in the OCB-K-VALUE table at either the POP or softswitch, by default, the K-value range is 1 through 3.
K-VALUE-MATCH
The K-VALUE-MATCH deactivation option requires the subscriber to enter a K-VALUE that matches the K-VALUE provisioned for the subscriber. If the subscriber enters a K-VALUE that does not match the value provisioned for K-VALUE, the subscriber receives an error announcement.
A success announcement is given on a successful deactivation, and an error announcement, indicating the type of error, is given if deactivation is unsuccessful.
Note
Refer to the Cisco BTS 10200 Softswitch Command Line Interface Reference Guide for provisioning details.
If a user enters an incorrect PIN repeatedly in a specified time period, the system can lock out further activation or deactivation attempts, as described in the "OCB Subscription and Provisioning (Release 4.4.1)" section.
OCB Interrogation (Release 4.4.1)
OCB interrogation for Release 4.4.1 operates as it did for Release 3.2.
OCB Invocation and Screening (Release 4.4.1)
For a calling party that is subscribed to OCB, and has activated the feature, OCB is invoked for every call made after the called party digits are dialed.
OCB Lockout Behavior (Release 4.4.1)
For the Enhanced OCB feature, if the FAIL-CNT (fail count), LOCK-OUT, and TIME-OUT tokens are provisioned in the OCB-PROFILE table, OCB lockout behaves according to those specifications.
If the OCB-PROFILE table is not provisioned, OCB lockout behaves according to the provisioning of the LOCK-OUT, TIME-OUT, and FAIL-CNT tokens in the FEATURE table.
The LOCK-OUT, TIME-OUT, and FAIL-CNT tokens in the FEATURE table are intended to prevent unauthorized changes or bypassing of OCB screening. If a user repeatedly enters the PIN incorrectly on the handset, the system can lock the line against both OCBA and OCBD. These tokens control the lockout behavior as described in Table 8.
Tip
Note that there is no service lockout when either the TIME-OUT or FAIL-CNT token is set to zero.
Class of Service Screening via Black and White List (Release 4.4.1)
Class of Service Screening via Black and White List for Release 4.4.1 operates as it did for Release 3.2.
OCB Feature Interactions (Release 4.4.1)
OCB feature interactions for Release 4.4.1 are the same as for Release 3.2.
Limitations and Restrictions (Release 4.4.1)
This section provides information on limitations and restrictions that apply to the enhanced OCB feature for Release 4.4.1.
Limitations On Reporting of Traffic Counters (Release 4.4.1)
Cisco BTS 10200 Softswitch OCB does not support the following traffic counters whenever it uses the OCB-Profile to block calls:
•
POTS_OCB_LOCAL_BLOCKED
•
POTS_OCB_NATL_BLOCKED
•
POTS_OCB_INTL_BLOCKED
Special Call Types (Release 4.4.1)
Call types such as Emergency, Fire, Police, Ambulance, and Toll-Free are not limited by OCB restrictions.
SIP Subscribers (Release 4.4.1)
If the service provider sets NANP_DIAL_PLAN="Y" in the dial plan for a SIP subscriber, the OCB feature will not operate properly.
Installing (Release 4.4.1)
There are no new, modified, or deleted requirements for installation procedures for the Cisco BTS 10200 Softswitch as a result of the enhancement to the OCB feature.
Configuring (Release 4.4.1)
Outgoing Call Barring is a superset of Class Of Service screening and includes all provisioning steps of COS. However, COS functionality itself, in OCB, is optional and need not be provisioned.
This section provides separate explanations for how OCB is provisioned by the service provider, by an individual subscriber, by a business group administrator, for a centrex office, or for an MLHG.
Office Provisioning (Release 4.4.1)
The following office provisioning example for OCB is new for Release 4.4.1.
Step 1
Register the OCB feature in the office:
add feature FNAME=OCB; tdp1=COLLECTED-INFORMATION; tid1=COS-TRIGGER; ttype1=R; feature_server_id=FSPTC235; description=Outgoing Call Barring; grp_feature=N;Step 2
Register the OCB activation, deactivation, and interrogation features into the office:
add feature FNAME=OCBx; tdp1=COLLECTED-INFORMATION; tid1=VERTICAL-SERVICE-CODE; ttype1=R; feature_server_id=FSPTC235; description=OCB act/deact/interr; grp_feature=N;
Note
For the steps of this procedure, OCB activation (OCBA), OCB deactivation (OCBD), and OCB interrogation (OCBI) are referred to interchangeably as OCBx.
Step 3
Register the COS feature in the office.
Note
See the provisioning notes for COS screening. This step is optional and is required only under two circumstances:
² COS screening functionality is required as a subset of OCB.
² BW-list screening functionality of OCB needs to be offered to the subscriber even if OCB is in a deactivated state.Step 4
Add/change the vsc code for OCBA.
add vsc fname=OCBA; digit-string=*54*;Step 5
Add/change the vsc code for OCBD.
add vsc fname=OCBD; digitstring=#54*;Step 6
Add/change the vsc code for OCBI.
add vsc fname=OCBI; digit-string=#54#;Step 7
Provision the OCB features as a service package.
add service id=ocb; FNAME1=OCB; FNAME2=OCBA; FNAME3=OCBD; FNAME4=OCBIStep 8
Provision feature parameters if required.
add feature fname=OCB; type1=pin-len; value1=5; type2=to; value2=20; type3=fail-cnt; value3=4; type4=lock-out; value4=60;Step 9
Provision a nature-of-dial screening exception list. Enter as many nature-of-dial records for OCB as required.
add nod-restrict-list fname=OCB; call-type=local;Step 10
Provision OCB feature parameters using the OCB-PROFILE if required.
add ocb-profile Id=ocb_prof; Max-k-values=5; All-calls-restrict-k-value=5; Fail-cnt=3; Pin-len=5; Lock-out=30; Time-out=30; Deactivation-option=K-VALUE-MATCH; Free-select-pin=Y;Step 11
Provision the OCB-K-VALUE if required.
add ocb-k-value Ocb-profile-id=ocb_prof; k-value=1; call-type=local, call-type=intl;
Note
For the call-type option, you can specify multiple call types.
Step 12
Provision base OCB behavior for the office.
add ca-config Type=DEFAULT-OCB-PROFILE-ID; Datatype=STRING; Value=ocb_prof;Step 13
Provision OCB behavior for the POP level.
add pop Id=<subscriber corresponding pop id>; Ocb-profile-id=ocb_prof;
Subscriber Provisioning (Release 4.4.1)
The following subscriber provisioning example is new for OCB since Release 3.2.
Step 1
Add the service to the subscriber's service profile:
add subscriber-service-profile sub-id=sub1_plano.com; service-id=ocb;Step 2
Add an initial password for the subscriber. (This step is optional.)
add subscriber-feature-data sub-id=sub1_plano.com; fname=OCB; type1=PASSWD; value1=1234;
Centrex Provisioning (Release 4.4.1)
Centrex provisioning for Release 4.4.1 is as it was for Release 3.2.
MLHG Provisioning
MLHG provisioning is similar to subscriber provisioning. See the section "Subscriber Provisioning (Release 4.4.1)" section.
Alternate Activation and Deactivation Method (Release 4.4.1)
This feature is deactivated by default when it is assigned to a subscriber. OCB can be activated and deactivated alternately by creating an entry in the Subscriber-feature-data table.
Use a CLI command similar to the following to activate OCB:
add subscriber-feature-data sub-id=sub_1; active=Y; fname=OCB; type1=K_VALUE;value1=1; type2=PASSWD; value2=1234;
Note
The value can be in the range 1 through 9.
Use a CLI command similar to the following to deactivate OCB:
add subscriber-feature-data sub-id=sub_1; active=N; fname=OCB;Provisioning Notes and Caveats (Release 4.4.1)
•
The K-VALUE for the subscriber in the Subscriber-feature-data table will be recorded by the system when the subscriber uses the OCBA feature.
•
The COUNT and TIME fields in the Subscriber-feature-data table are used by the operator to manually reset a locked-out subscriber. To unlock a locked-out subscriber, set both fields to '0'.
•
The PASSWD provisioned in the Subscriber-feature-data table can be optional if FREE-SELECT-PIN=Y.
Operating (Release 4.4.1)
This section explains how the enhancements to the OCB feature affect the following operational areas:
•
Billing Fields (Release 4.4.1)
•
Traffic Counters for Blocking Different Call Types (Release 4.4.1)
•
Command Responses (Release 4.4.1)
•
Cause Codes and Announcements (Release 4.4.1)
•
Recoverable and Non-Recoverable Error Codes (Release 4.4.1)
Billing Fields (Release 4.4.1)
A billing record is generated whenever OCB is activated, deactivated, interrogated and invoked. For the Release 4.4.1 enhancement to OCB, no new interface requirements are identified. However, the FeatureData field of the OCBA feature is extended from 3 to 9 values as shown in Table 9.
Feature Server Derived Call Data (Release 4.4.1)
This section describes the data related to the OCB feature that is placed within various fields in the call detail block (CDB) records. This data is generated by the Feature Servers, either internal or external, whenever a feature is invoked during the context of a given call. Up to three feature instances can be captured in a single call detail block. The format of the data and the possible values are shown in the following sections. Each block of feature data contains up to four sub-fields, as follows:
Note
This section provides only the data related to the OCB feature. For the complete description of the feature server derived call data for the Cisco BTS 10200 Softswitch, see the Cisco BTS 10200 Softswitch Billing Interface Guide.
•
ServiceId—a string describing which services/features were involved in this billing event. The possible values are:

•
Modified Call Agent Configuration (CA-CONFIG) table [Chapter 1]
•
Modified Point of Presence (POP) table
•
OCB PROFILE table
•
OCB-K-VALUE table
Modified CA-CONFIG Table (Release 4.4.1)
For office-level provisioning, the CA-CONFIG table includes the following token.
Note
For the full description of the CA-CONFIG table, see Chapter 1: Call Agent Provisioning in the Cisco BTS 10200 Softswitch Command Line Interface Reference Guide for Release 4.1, 4.2, 4.3, 4.4,and 4.5.
Syntax Description
DEFAULT-

PROFILE-IDSpecifies the default office-based Outgoing Call Barring Profile ID that is used if the POP-specific OCB-PROFILE_ID is not provisioned.
STRING:
Modified Point of Presence Table (Release 4.4.1)
To support the OCB feature, the Point of Presence (POP) table includes the following token.
Note
For the full description of the POP table, see Chapter 2: Office Provisioning in the Cisco BTS 10200 Softswitch Command Line Interface Reference Guide for Release 4.1, 4.2, 4.3, 4.4,and 4.5.
Syntax Description
OCB-PROFILE-ID
Foreign key: OCB Profile table.The OCB Profile ID.If not provisioned, the OCB feature uses the default values defined in the Feature table.
VARCHAR(16): 1-16 ASCII characters.
OCB PROFILE Table (Release 4.4.1)
The Outgoing Call Barring (OCB) Profile (ocb-profile) table defines an OCB Profile. The OCB Profile can be defined at a POP level by provisioning the ocb-profile-id, in the Point of Presence (POP) table, or at the office level by provisioning the default-ocb-profile-id in the Call Agent Configuration (CA-CONFIG) table. If an OCB Profile id is not provisioned in either the POP table or the CA-CONFIG table, then a default OCB behavior is used.
Note
If an ocb-profile-id is provisioned in the POP table and CA Config table, the value in the POP table has precedence.
Table Name: OCB-PROFILE
Table Containment Area: FSPTC, EMS
Command Types
Show, add, change, and delete

Syntax Description
OCB-K-VALUE Table (Release 4.4.1)
The OCB K Value (ocb-k-value) table associates call types to a particular k-value. A k-value is an integer from 1 to 9 that is dialed by a user to select different levels of OCB restrictions. Multiple call types can be provisioned against each k-value. A call type can be associated with multiple k-values. Each call type/k-value combination generates one unique record in the EMS.
Note
Multiple Call Types can be specified during add and delete commands. If multiple call types are specified in a command and one of the call types is invalid, then the whole command is rejected and must be re-provisioned.
Note
Use the forced token to delete all records against a particular K-value or to delete all records for OCB-PROFILE-ID.
