TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be
defined in the description of any object defined using this type.
If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks
The value of sysUpTime when the call associated to this entry was started. This will be useful for an NMS to retrieve all calls after a specific time. Also, this object can be useful in finding large delays between the time the call was started and the time the call was connected. For ISDN media, this will be the time when the setup message was received from or sent to the network.
callActiveIndex
INTEGER (1..2147483647) · Integer32
Small index variable to distinguish calls that start in the same hundredth of a second.
cvCommonDcCallActiveConnectionId
1.3.6.1.4.1.9.10.55.1.1.1.1.1
CvcGUidRepresents a Global Call Identifier. The global call identifier is used as an unique identifier for an end-to-end call. A zero length CvcGUid indicates no value for the global call identifier. SIZE (0..16) · OCTET STRING
The global call identifier for the network call.
cvCommonDcCallActiveVADEnable
1.3.6.1.4.1.9.10.55.1.1.1.1.2
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
The object indicates whether or not the VAD (Voice Activity Detection) is enabled for the voice call.
The negotiated coder rate. It specifies the transmit rate of voice/fax compression to its associated call leg for the call. This rate is different from the configuration rate because of rate negotiation during the call.
cvCommonDcCallActiveCodecBytes
1.3.6.1.4.1.9.10.55.1.1.1.1.4
INTEGER (10..255) · Integer32
Specifies the payload size of the voice packet.
cvCommonDcCallActiveInBandSignaling
1.3.6.1.4.1.9.10.55.1.1.1.1.5
CvcInBandSignaling1 = cas2 = none3 = cept4 = transparent5 = gr303Represents the type of in-band signaling used between the two end points of the call and is used to inform the router how interpret the ABCD signaling data bits passed as part of the voice payload data.
cas - specifies interpret the signaling bits as
North American Channel Associated signaling.
none - specifies no in-band signaling or signaling
is being done via an external method (e.g CCS).
cept - specifies interpret the signaling bits as
MELCAS transparent - specifies do not interpret or translate the signaling bits.
gr303 - specifies interpret the signaling bits as
GR303 · Integer32
Specifies the type of in-band signaling being used on the call. This object is instantiated only for Connection Trunk calls.
cvCommonDcCallActiveCallingName
1.3.6.1.4.1.9.10.55.1.1.1.1.6
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..64) · OCTET STRING · hint 255t
The calling party name this call is connected to. If the name is not available, then it will have a length of zero.
cvCommonDcCallActiveCallerIDBlock
1.3.6.1.4.1.9.10.55.1.1.1.1.7
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
The object indicates whether or not the caller ID feature is blocked for this voice call.
cvCommonDcCallHistoryTable
1.3.6.1.4.1.9.10.55.1.2.1
Index: cCallHistoryIndex
This table is the Common extension to the call history table of IETF Dial Control MIB. It contains Common call leg information about a network call leg.
A monotonically increasing integer for the sole purpose of indexing call disconnection events. When it reaches the maximum value, an extremely unlikely event, the agent wraps the value back to 1 and may flush existing entries.
cvCommonDcCallHistoryConnectionId
1.3.6.1.4.1.9.10.55.1.2.1.1.1
CvcGUidRepresents a Global Call Identifier. The global call identifier is used as an unique identifier for an end-to-end call. A zero length CvcGUid indicates no value for the global call identifier. SIZE (0..16) · OCTET STRING
The global call identifier for the gateway call.
