For OCs descrip

21、tion the following table is used. Table 1: OCS generic description The column M/C indicates whether the information presented by the attributes/actions/notifications is mandatory(M) or conditionai( C) . The column “Value Set“ indicates whether the attribute is single-valued or set-valued (see 1TU-T

22、Recommendation X.720 lS, subclause 5.1.2.2). The column “Operation“ indicates the operations possible on the attribute. Combination of key-attributes value shail be unique among all instances of a given OC. An asterisque * following an attribute name indicates a key attribute. Important notice: The

23、conflict resolution that shall occur when several instances of a given OC match a specific call is out of the scope of the present document.

24、i a The OC analysiscriteria describes the management information needed to make a selection among possible destinations. For certain calls, e.g. service numbers and originating calls of virtual private networks, it is possible that initial digits need to be modified before the destination can be ide

25、ntified. The destination associated with this new digit string can then be determined by another instance of OC analysislriteria. Table 2: AnalysisCriteria description IobjectManagemen tNotifications Package The following attributes describe the OC analysislnteria: - analysiscriteriald; This attribu

26、te is the object identifier attribute (Relative Distinguished Name (RDN) of OC analysiscriteria. - des tina tionlode; This attribute characterizes a destination by specifying the Country Code (CC), or/and area code, orland exchange identifying code, orland individual line number etc. to which the ca

Cal

32、attribute indicates the type of destination - extSchedulingA ttribute; This attribute provides the scheduling information in the Scheduled Managed Object (SMO), if external scheduling is supported as in EN 301 098 131. - externalSchedulerName: This attribute is used in the SMO for referencing the ex

33、ternal SOS. (see ITU-T Recommendation X.746 1201) - numberOfDigits; This attribute indicates the number of digits in the digit string. The existence of multiple analysiscriteria instances with different values for this attribute allows the administration of variable length digit strings that shall b

34、e routed to the same destination. It also allows the specification of a destination that depends not only on the leading digits as indicated in the attribute destinationCode, but also on the length of the digit string. In this way digit strings with identical leading digits, but with different lengt

35、hs can be routed to different destinations. When a specific number of digits is specified, this number cannot be smaller than the number of digits in the digit string as specified in the destinationcode attribute. - camerDataInstance. This atlribute allows the selection of destinations depending on

36、the dialled or assigned carrier code of the call. 7.2 call H istory This OC describes criteria and/or restrictions related to the history of a call, e.g. the number of satellite links. It can be used, for example, to restrict the propagation delay. Table 3: callHistory description CallHistoryld Sing

This attribute represents the number of satellite links in the history of the call. The number of hops allowed for a certain caii can be limited. In general, the limita
