1 System Overview
This chapter provides a high-level overview of the application. It explains the basic functionality of the system and lists the main components.
It is not intended to advise on any specific Oracle Communications Convergent Charging Controller network or service implications of the product.
About Advanced Control Services
-
Calls to specific dialed numbers (service numbers)
-
Calls from specific calling numbers (CLI numbers)
-
All calls triggered to a specified INAP service key
Call Processing and Features
The call processing consists of an arbitrary call-processing diagram, which makes decisions and performs actions chosen from a rich set of feature nodes.
These nodes include basic features such as time routing (day, week, year), proportional routing, calling and called prefixes, special numbers, failover routing, and VIP customers. They include telephony actions such as announcement playing, IVR prompting, number redirection, account code, and PIN entry.
Other Features
In addition, many ancillary functions are provided, such as detailed logging and analysis information, event counting and branching, customer self-administration, multi-lingual support for announcements and user interfaces, and many more features as described in ACS User's Guide.
Call Routing Services
These features make ACS an ideal application to provide a wide range of common and popular call routing services, like:
- FreePhone
- Premium Rate
- TeleVote
- Follow Me/Personal Numbering
- Call Screening (Incoming)
It is also an ideal application for common residential or small business services, like:
- Account Code Validation
- Toll Barring (With PIN Override)
- Hot Line
- Call Screening (Outgoing)
- Basic Friends & Family

Note: Only relevant to the 0800 service. |
| Temporary Storage |

| VPN Network Profile |
Contains most of the information you can specify in the VPN edit network, like:
Note: Only relevant if you have the VPN service installed. |
| VPN Station Profile |
Contains most of the information you can specify in the VPN edit station, like:
Note: Only relevant if you have the VPN service installed. |
ACS Primary Tags
Table 1-2 provides a list of ACS primary tags.
Note:
-
These tags are preloaded on installation of ACS and are displayed on the ACS Configuration screen, in the Profile Tag Details tab.
-
Do not use reserved ACS primary tag to create the custom profile tag. Custom profile tag should be added with profile tag number starting from max profile tag number in the system + 1.

Note:
Each service may have its own specific tags in a separate tag range.About ACS Functions
Calls using the ACS service will follow a control plan, and given varying circumstances will be directed to a terminating point. A control plan is effectively a flow chart defining the decisions and actions made to determine the routing of a call.
A control plan may consist of multiple different decision or action nodes called feature nodes. Each feature node has one input and a number of outputs determined by the type of feature node. The exceptions to this are the Start and End feature nodes that have only one output or one input respectively.
Each output from a feature node can lead to another feature node. The output used when exiting a feature node during call processing is determined by the functionality of that feature node. For example, a day of week feature node has multiple outputs, which are used depending on the current day of the week, and an internal customer defined mapping of the day of week to an output.
