INTEGER1 = hairpin2 = reject3 = playMessage · Integer32

The type of call treatment to apply on a new call when a call resource threshold is exceeded. This treatment is applicable if the threshold action (ccacSysRpAction) includes 'treatment(3)' or 'busyoutAndTreatment(4)'. hairpin(1) - Connect the call back to the PSTN via another telephony port. reject(2) - Reject the call, using cause code specified in ccacSysRejectCode playMessage(3) - Reject the call and send the specified audio message. The audio file used for 'playMessage(3)' is specified in ccacSysPlayMessageFile. The 'playMessage(3)' option only applies to Voice over ATM, IP, or FrameRelay calls. For other types of calls, a value of 'playMessage(3)' is equivalent to 'reject(2)'.

Reference: ITU-T Recommendation Q.931, ISDN user-network interface layer 3 specification.

This object specifies the numeric code to be returned to the call control agent (MGC) when a call is rejected as a result of the call resource thresholds being exceeded. This code is used when the signalling protocol supports call rejection cause codes. This does not apply to channel associated signalling (CAS).

This object is used to reject the calls even when an interface is 'busyout' as the action of call treatment.

SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416]. Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (0..255) · OCTET STRING · hint 255t

The name of the audio file to be played for call rejections if the value of ccacSysTreatment is 'playMessage(3)'. The format of the filename is system specific. If no file is configured, this object contains a zero length string.

Integer32 (100..2000) · millisecond

This object defines the time length for each step in a sliding window of ccacSysCallSpike.

Integer32 (0..2147483647) · calls

This object is used to define a threshold for incoming call spike. The number of incoming calls is counted within a sliding window which is broken into ccacSysSlidingWindowSteps. Each step has an equally time interval defined in ccacSysSlidingWindowSize. The sliding window size can be calculated from ccacSysSlidingWindowSteps and ccacSysSlidingWindowSize two objects. The 'sliding window' = ccacSysSlidingWindowSteps * ccacSysSlidingWindowSize For example, if ccacSysSlidingWindowSteps is 5 AND ccacSysSlidingWindowSize is 200 (ms), then the 'sliding window' will be 1 second. ccacSysCallSpike sets the maximum number of incoming call in a sliding window. Set this object to value '0' will disable call spike threshold and will reset the value of ccacSysSlidingWindowSteps and ccacSysSlidingWindowSize to default value. The value of this object is '0', it indicates the call spike threshold is disabled.
