Feature Overview
This feature introduces the ability to modify the A-number based on the Presentation Indicator in the
Initial Address Message (IAM) message or its equivalent. In this feature, A-numbers encountering this
result in analysis are modified with a user-defined prefix when the value of the stored presentation
restriction data indicates that the number is restricted or unavailable. If this is not the case, the A-number
is not modified and analysis continues.

Conditional A-Number Modification
Feature Overview
Note
If additional instances of A-number modification occur as analysis continues, the A-number can be
further modified.
This feature can be used for SS7 ITU and SS7 UK routes. The analysis process for this feature is as
follows:
Step 1
Extracting the A-number or Calling Line Identity (CLI) information. This information is found in the
following parameters:
•
For UK networks—Presentation Number CLI (PN-CLI) or Network Number CLI (NN-CLI) if
PN-CLI is not present.
•
For ITU networks—Calling Party Number CLI (CgPn-CLI)
Step 2
Extracting the CLI Blocking Indicator (CBI), if present (only in UK networks).
Step 3
Converting the NN-CLI to International format and setting Nature of Address (NOA) accordingly.
Step 4
Determine the privacy marking associated with the CLI information.
Step 5
Adding the user-configured prefix to the A-number. The configured digits indicate the privacy status of
this number.
Description of CLI Information
The CLI information is carried in two distinct parameters which may both be passed during signaling
for the same call. Each provides information for a different reason as given below:
Note
•
CgPn-CLI/NN-CLI—Used to identify the point of ingress to the PSTN network and can be used for
the purposes of billing identification/call tracing purposes. This number is sometimes referred to as
the Full CLI.
•
PN-CLI—Used to provide the called party with a return number that can be dialed. It is normally
passed where the number the caller wishes to be displayed to the called party differs from the point
of access to the PSTN network. This may for example be provided for telemarketing when working
from home, so that an office number is provided for any call back rather than the home number.
The number that is passing through the Internet Dial Platform on to the Radius server is the
CgPn-CLI/NN-CLI and it is this number that must be prefixed when the privacy settings demand it.
Determination of Privacy Status - UK Networks
The CLI privacy status for UK networks is given using the following three classifications:•
Available—Calling party has access to CLI Presentation (CLIP)/CLI Restriction (CLIR)
supplementary services and has not chosen to prevent display of their CLI information.
•
Withheld—Calling party has access to CLIP/CLIR services and has chosen to prevent display of
their CLI information.
Cisco MGC Software Release 9.5(2)
2
Conditional A-Number Modification
Feature Overview
•
Unavailable—Calling party either does not have access to CLIP/CLIR services or there is no CLI
information to pass. With this category the information is still passed in SS7 messaging unless the
CLI information is actually absent.
For this feature, the privacy associated with the PN-CLI is used to determine the conditional number
modification and if that number is not present, then the privacy marking on the NN-CLI is used. If
applicable, the resulting prefix digits are applied to the A-number.
Privacy is determined by a combination of the Identity Qualifier (IQ) in the respective CLI parameters
with the IAM message indicator field CBI. When a PN-CLI is present, the privacy status is taken from
the associated IQ alone, as the presence of a PN-CLI implies that a calling party has access to
CLIP/CLIR services, so CBI is ignored. When no PN-CLI is present, the NN-CLI is checked for privacy
and the CBI is also checked and has a bearing on the status.
The following table provides the method of privacy determination for each of the CLI numbers:

Determination of Privacy Status - ITU Networks
The CLI privacy status for ITU networks is given using the following three classifications:•
Presentation allowed (Available)—Calling party has access to CLIP/CLIR supplementary services
and has not chosen to prevent display of their CLI information.
•
Presentation restricted (Withheld)—Calling party has access to CLIP/CLIR services and has chosen
to prevent display of their CLI information.
•
Address not available (Unavailable)—Calling party either does not have access to CLIP/CLIR
services or there is no CLI information to pass. With this category the information is still passed in
SS7 messaging unless the CLI information is actually absent.
For this feature, the value of the presentation restriction indicator field in the CgPn-CLI is used to
determine the conditional number modification. The presentation restriction indicator field is two bits in
length and value of that field indicates privacy status as follows:
•
00—Presentation allowed (Available)
•
01—Presentation restricted (Withheld)
•
10—Address not available (Unavailable)

Conditional A-Number Modification
Feature Overview
Expected A-Number Format
To keep the CLI information uniquely identifiable regardless of what type of network it enters, the CLI
is reformatted into an International number (ITU-T format) where it is not already presented as such.
The following CLI number formats will be, where appropriate, re-formatted to International format.
•
ITU International format—NOA is given as International and the number comprises the Country
code followed by the National significant number (for example, 44 1444 234567).
•
ITU National format—NOA is given as National and the number comprises the National significant
number (for example, 1444 234567).
•
UK Specific International format—NOA is given as National and the number is comprised of a zero
prefix followed by Country code and National significant number (for example, 0 44 1444 234567).
Benefits
This feature provides the following benefits:
Identifies Restricted Calls
Provisioning this feature enables the Cisco PGW 2000 to add a prefix to calls that have a Restricted CLI
value. That prefix will enable RADIUS servers in your network to identify that call as Restricted.
Restrictions
This feature has the following restriction:
•
When provisioning a conditional A-number modification value, you can only insert digits into the
string for that command instance. In any other type of A-number modification operation, you can
add and subtract digits in the same command instance.

Adding Digit Modification String Data
The Digit Modification is accessed by the results to yield a string of numbers (digits) to apply to an
A-number or B-number. To add a DIGMODSTRING list and add digit strings, complete the following
steps:
Step 1
Enter the following command on the active Cisco MGC at the Man-Machine Language (MML) prompt:
mml> numan-add:digmodstring:custgrpid=”cgid”, name=”dname”, digstring=”dstring”
Where:
Note
•
cgid—Indicates the customer group ID. This is a 4-digit alphanumeric string.
•
dname—MML name of the digit modification string.
•
dstring—String of digits to modify.
Over-decadic digits can be used in your prefix. You must ensure that only over-decadic digits B and C
are used in your prefix if the call data is routed through a H.323 network. B and C are the only
over-decadic digits that are supported in H.323. If you use any of the other over-decadic digits in your
prefix, once the call data enters a H.323 network through the Cisco H.323 Signaling Interface (HSI) the
A-number will be forwarded without those over-decadic digits.
For example, to add an digit modification string, 666, called restpfx, enter the following MML
command:
mml> numan-add:digmodstring:custgrpid=”T002”,name=”restpfx”,digstring=”666”
Step 2
To verify the command was executed successfully, enter the command:
mml> numan-rtrv
Step 3
Tip
Repeat steps 1 and 2 for each entry you add to the digit modification string list.
An implied index, which contains a single string of digits to be applied to the calling number or called
number, is used to access the DIGMODSTRING list.
Adding A-Number Modification Result Table Data
Results are used with number analysis. To add an A-number modification result table to the dial plan,
complete the following steps:
Step 1
Enter the following command on the active Cisco MGC at the MML prompt:
mml> numan-add:resulttable:custgrpid=”cgid”, name=”resnam”, resulttype=”AMODDIG”,
dw1=”dw1”, dw2=”0”, dw3=”dw3”, dw4=”1”, setname=”snam”
Where:
•
cgid—Indicates the customer group ID. This is a 4-digit alphanumeric string.
Cisco MGC Software Release 9.5(2)
6
Conditional A-Number Modification
Creating Dial Plan Data
Note
Caution
•
resnam—MML name of the result table.
•
dw1 (dataword1)—Provides an index into the Script table in the MGC database, where the details
of the Script table, such as gateway type, language, location, and so on are stored. This is an integer.
When adding an index in the Script table, be sure the value you enter is a valid value in the Script table.
Dataword 2 (dw2) cannot be used to subtract digits when you are using dataword 4 (dw4) to add
A-number modification result data.
•
dw3 (dataword3)—Indicates if an optional Address Complete Message (ACM) is to be sent when
the confirmation of script invocation is received (for dw2, CallType = 1) from the gateway. This is
an integer.
•
sname—Indicates the MML result set name for this AMODDIG result type. The set name is user
configured and can be as many as 20 alphanumeric characters.
For example, to add an A-digit tree to the customer group ID t100, enter the following MML command:
mml> numan-add:resulttable:custgrpid=”T002”, name=”result5”, resulttype=”AMODDIG”,
dw1=”1”, dw2=”0”, dw3=”restpfx”, dw4=”1”, setname=”setname1”
Step 2
To verify the command was executed successfully, enter the command:
mml> numan-rtrv
Step 3
Repeat steps 1 and 2 for each A-number modification result table you want to add.
Adding A-Number Digit Tree Data
The A-Digit Tree contains entries, in blocks of sixteen, for each calling number. Its output is an index
to the Result table or an indication that no further action is necessary. To add an A-Digit Tree to your
dial plan, complete the following steps:
Step 1
Enter the following command on the active Cisco MGC at the MML prompt:
mml> numan-add:adigittree:custgrpid="cgid", digitstring="dstring", callside="cs",
setname="snam"
Where:
•
cgid—Indicates the customer group ID. This is a 4-digit alphanumeric string.
•
dstring—Defines the digit string.
•
cs—Indicates the side of the call, either originating or terminating.
•
sname—Indicates the MML result set name for this A-number digit tree. The set name is user
configured and can be as many as 20 alphanumeric characters.
For example, to add an A-digit tree to the customer group ID t100, enter the following MML command:
mml> numan-add:adigittree:custgrpid="t100",digitstring="703484",callside="originating",
setname="setone"
Step 2
To verify the command was executed successfully, enter the command:

Dial Plan Examples
mml> numan-rtrv
Step 3
Repeat steps 1 and 2 for each entry you add to the A-digit tree.
Enabling A-Number Normalization
Enabling A-number normalization results in the removal of leading zeros from National (0) or
International (00) European prefixes. This feature adds the ability to remove the leading zero from a
UK-specific International format CLI (and the corresponding NOA change to International). In addition,
this functionality can now be applied to both trunk groups and signaling services.
To enable A-number normalization for the trunk group or signaling service associated with your dial
plan, complete the following steps:
Step 1
Enter the following command on the active Cisco MGC at the MML prompt:
mml> prov-add:property:name="comp_name",anumnormalise=1
Where:
•
property—MML component type for trunk group or signaling service properties. Select one of the
following:
– trnkgrpprop—MML component for trunk group properties.
– sigsrvprop—MML component for signaling service properties.
•
comp_name—MML name for the trunk group or signaling service on which you want to enable
A-number normalization.
For example, to enable A-number normalization on a signaling service called va-5300-a, enter the
following MML command:
mml> prov-add:sigsvcprop:name=”va-5300-a:,anumnormalise=1
Step 2
To verify the command was executed successfully, enter the command:
mml> prov-rtrv
Step 3
Repeat steps 1 and 2 for each trunk group or signaling service on which you want to enable A-number
normalization.

AMODDIG
The AMODDIG result type is used to modification the digits of the A-number. It is returned from
pre-analysis, A-number analysis, and B-number analysis. The datawords are used to control the digit
modification process as follows:
•
Application point (Dataword 1)—The point in the A-number where the digit modification begins.
The valid values are:
– 1—The start of the number.
– 2 to 97—A point within the number.
– 98—The end of the number
•
Number of digits to remove (Dataword 2)—The number of digits to be removed from the A-number,
starting at the application point.
•
Modification name (Dataword 3)—A string of digits to be entered into the A-number, starting at the
application point. The value can be 0 (default) or any integer string.
•
Conditional indication (Dataword 4)—Indicates that the A-number is to be modified when certain
conditions are met. The valid values are:
– 0—Unconditional modification.
– 1—Presentation restriction dependent.
Note
The Conditional indication is added in Release 9.5(2), Patch 23. Previously, dataword 4 had no
associated function.
Cisco MGC Software Release 9.5(2)
10
Conditional A-Number Modification
Reference Information
Note
When the conditional indication (dataword 4) is set to 1, you cannot provision a number of digits to
remove (dataword 2) within that same command instance.
In an unconditional modification example, if the application point = 1, the number of digits to remove =
5, the modification name = 1321, and the conditional indication = 0, the modification begins at the start
of the digit string, removes 5 digits, and replaces them with the digit string 1321. This yields a A-number
as follows:
•
A-number received before analysis = 01444 567891
•
A-number post analysis = 1321 567891
In a conditional modification example, if the application point = 98, the number of digits to remove = 4,
the modification name =1321, and the conditional indication = 1, the modification begins at the end of
the digit string, removes 4 digits, and replaces them with the digit string 1321, if the presentation
restriction is met. If the presentation restriction is met, this yields a A-number as follows:
•
A-number received before analysis = 12345567891
•
A-number post analysis =12345561321
If the presentation restriction is not met, the A-number is not modified.
Depending on the analysis area that invokes it, the AMODDIG result type has different functionality.
The following are examples of this different functionality.
•
In Pre-Analysis there are currently four serial stages that can produce the AMODDIG result type.
In Pre-analysis, the results are cumulative. For example, if the CPC stage generates an AMODDIG
result type, then the A-number is modified according to the result and this modified number then is
the new A-number passed as input to the next Pre-analysis stage (TMR analysis). If the TMR
analysis provokes another AMODDIG result type, then it further modifies the number and so on.
Even though multiple modifications like this would seem excessive and unnecessary, the capability
exists to ensure the required flexibility is provided.
•
In Number analysis (A-number or B-number), functionality is different. Here digit analysis is
applied (digit by digit) and it is possible to have the AMODDIG result type at multiple points if
required. However, it is only the last modification result type that is applied.
If multiple A-number modification results are collected throughout analysis, each data set effectively
over-writes and replaces the former one. This means that the last collected A-number modification result
is the one that is applied. This is the case regardless of which phase of analysis the results occur (for
example, in pre-analysis and B-number analysis) or within one phase of digit tree analysis (for example,
in A-number or B-number analysis).
For example, if the received A-number is 1234 and at "1" an AMODDIG result type is received making
the A-number 441234, the digit string is modified and analysis continues according to the digit analysis
configuration. If another AMODDIG result type is received at 1234, making the A-number 551234, the
earlier AMODDIG result type ("1") is discarded and the A-number now sent forward is 551234.
Conditional A-Number Modification Result Limitation
In a Conditional A-number Modification result, the privacy status of the CLI is assessed to determine
whether to apply a modification string to the CLI. This prefix is applied to the CLI once all other number
prefixing and normalization (that is, country code addition) is complete. To achieve this, the modifying
digits are captured during analysis and stored for later application post-analysis and post-country code
preparation of the number.
Cisco MGC Software Release 9.5(2)

Conditional A-Number Modification
Obtaining Documentation
Digit removal is not allowed as part of Conditional A-number modification to prevent the possible
stripping off of country codes and CLI corruption. Therefore, when the Conditional A-number
modification result is enabled through the value specified in dataword 4, only the use of data words 1, 3
and 4 is permitted, omitting the digits-to-remove specified in dataword 2.
Combinations of Conditional and Unconditional A-Modification Results
You can have both Conditional and Unconditional A-number modification results as a combination in
analysis, with some limitations. You can combine Conditional and Unconditional A-number
modification results by provisioning each in a different phase of analysis, but you cannot have both in
one phase of analysis. The rules are as follows:
•
In Pre-analysis there are currently 5 stages which all have access to the same pool of result types.
You can provision an Unconditional A-number modification result in one of these stages and it
becomes input to the subsequent stages where you could have a Conditional A-number modification
result. You cannot have both in one result set in a single pre-analysis stage as only the last result
retrieved applies.
•
In A-number analysis you can only have a single Unconditional or Conditional A-number
modification result, even when the results occur at different points in the digit tree and hence in
different result-sets. You cannot have a combination of both either in a single result-set or in
different result-sets. In this case only the last result retrieved applies.
•
In B-number analysis you can only have a single Unconditional or Conditional A-number
modification result, even when the results occur at different points in the digit tree and hence in
different result-sets. You cannot have a combination of both either in a single result-set or in
different result-sets. In this case only the last result retrieved applies.
•
You can have a Conditional A-number modification result in Pre-analysis and then later an
Unconditional A-number modification result in A-number analysis (or vice-versa).
•
You can have a Conditional A-number modification result in Pre-analysis and then later an
Unconditional A-number modification result in B-number analysis (or vice-versa).
•
You can have a Conditional A-number modification result in A-number analysis and then later an
Unconditional A-number modification result in B-number analysis (or vice-versa).

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you might have identified a
vulnerability in a Cisco product, contact PSIRT:
•
Emergencies — [email protected]
An emergency is either a condition in which a system is under active attack or a condition for which
a severe and urgent security vulnerability should be reported. All other conditions are considered
nonemergencies.
•
Nonemergencies — [email protected]
In an emergency, you can also reach PSIRT by telephone:
Tip
•
1 877 228-7302
•
1 408 525-6532
We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive
information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.

Obtaining Technical Assistance
Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco
Technical Support & Documentation website on Cisco.com features extensive online support resources.
In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC)
engineers provide telephone support. If you do not have a valid Cisco service contract, contact your
reseller.
Cisco Technical Support & Documentation Website
The Cisco Technical Support & Documentation website provides online documents and tools for
troubleshooting and resolving technical issues with Cisco products and technologies. The website is
available 24 hours a day, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user
ID and password. If you have a valid service contract but do not have a user ID or password, you can
register at this URL:
http://tools.cisco.com/RPF/register/register.do
Note
Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting
a web or phone request for service. You can access the CPI tool from the Cisco Technical Support &
Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose
Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco
Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by
product ID or model name; by tree view; or for certain products, by copying and pasting show command
output. Search results show an illustration of your product with the serial number label location
highlighted. Locate the serial number label on your product and record the information before placing a
service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
Obtaining Additional Publications and Information
Information about Cisco products, technologies, and network solutions is available from various online
