Table 2:

List of service independent building blocks for Capability Set 1

Algorithm:

Applies a mathematical algorithm to input data to produce a data result.

Charge:

Determine special charging treatment for the call in addition to that normally performed by the basic call process.

Compare:

Performs a comparison of an identifier against a specified reference value.

Distribution:

Allows the user to distribute calls to different logical ends of the SIB dependent of user specified parameters.

Limit:

Limit the number of calls related to a service feature even though calls may not be causing congestion. Such limiting will be based on user specified parameters.

Log Call Information:

Log detailed information for each call into a file. The collected information may be used for management services, e.g. statistics.

Queue:

Provide sequencing of calls to be completed to a called party.

Screen:

Perform a comparison of an identifier against a list to determine whether the identifier has been found in the active list.

Service Data Management:

Enables the user's specific data to be replaced, added, changed, retrieved, incremented, decremented or deleted.

Status Notification:

Provide the capability to request for the status and/or status changes of network resources, e.g. subscriber line.

Translate:

Translate input data to output data, e.g. a Freephone number to a network routing number.

User Interaction:

Allows information to be exchanged between the network and the calling or called party.

Verify:

Provide confirmation that information received is consistent with the expected form of such information.

Basic Call Process:

For CS-1 the Basic Call Process has been defined as a specialised SIB which provides the capabilities for basic calls. See Q.1204 and Q.1214 for a more comprehensive description of the Basic Call Process.
