The Voice Common Configuration Table. It contains information about the voice related configuration parameters for both analog and digital telephony interfaces.
InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.

cvIfCfgNoiseRegEnable
1.3.6.1.4.1.9.9.64.1.1.1.1.1
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
The object indicates whether or not the background noise should be played to fill silence gaps if VAD is activated. The default value of this object is enabled.
cvIfCfgNonLinearProcEnable
1.3.6.1.4.1.9.9.64.1.1.1.1.2
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
The object indicates whether or not the Nonlinear Processing is enabled for the interface. The default value of this object is enabled.
cvIfCfgMusicOnHoldThreshold
1.3.6.1.4.1.9.9.64.1.1.1.1.3
Integer32 (-70..-30) · dBm
The object specifies the Music On Hold Threshold for the interface. The default value of this object is -38 dBm.
cvIfCfgInGain
1.3.6.1.4.1.9.9.64.1.1.1.1.4
Integer32 (-6..14) · dB
This object contains the amount of gain inserted at the receiver side of the interface. The input gain settings only define a gain/loss relative to the 0 dB setting. The absolute loss at the 0 dB setting could be implementation dependent based on the desired network loss plan. The default value of this object is 0 dB (decibel).
cvIfCfgOutAttn
1.3.6.1.4.1.9.9.64.1.1.1.1.5
Integer32 (0..14) · dB
This object contains the amount of attenuation inserted at the transmit side of the interface. The output attenuation settings only define a loss relative to the 0 dB setting. The absolute loss at the 0 dB setting could be implementation dependent based on the desired network loss plan. The default value of this object is 0 dB (decibel).
cvIfCfgEchoCancelEnable
1.3.6.1.4.1.9.9.64.1.1.1.1.6
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
The object specifies whether or not the Echo Cancellation is enabled for the interface. The default value of this object is enabled.
The object indicates the connection mode of the interface. normal - the interface acts normally to handle incoming and outgoing call.
trunk - the interface acts in trunking mode. trunking mode
causes two interfaces (on either the same or different routers) to be always conferenced together, and for telephony signaling to be passed transparently through the VoIP system rather than trapped and interpreted by the session application on the router(s).
plar - the interface acts in PLAR (private line automatic
ringdown) mode. PLAR is handled by associating a peer directly with an interface such that when the interface goes off-hook, that peer is used to setup the second call leg and conference them together without the caller having to dial any digits. tieline- the interface acts in tie-line mode. This specifies a connection that emulates a temporary tie-line trunk to a PBX. A tie-line connection is automatically set up for each call and torn down when the call ends.
cvIfCfgConnectionNumber
1.3.6.1.4.1.9.9.64.1.1.1.1.9
DisplayStringRepresents textual information taken from the NVT ASCII
character set, as defined in pages 4, 10-11 of RFC 854.
To summarize RFC 854, the NVT ASCII repertoire specifies:
- the use of character codes 0-127 (decimal)
- the graphics characters (32-126) are interpreted as US ASCII
- NUL, LF, CR, BEL, BS, HT, VT and FF have the special meanings specified in RFC 854
- the other 25 codes have no standard interpretation
- the sequence 'CR LF' means newline
- the sequence 'CR NUL' means carriage-return
- an 'LF' not preceded by a 'CR' means moving to the same column on the next line.
- the sequence 'CR x' for any x other than LF or NUL is illegal. (Note that this also means that a string may end with either 'CR LF' or 'CR NUL', but not with CR.)
Any object defined using this syntax may not exceed 255 characters in length. SIZE (0..32) · OCTET STRING · hint 255a
This is the E.164 phone number that is used to establish connection with trunking mode or PLAR mode.
If the cvIfCfgConnectionMode is 'normal', then this
object will be a zero length string.
cvIfCfgInitialDigitTimeOut
1.3.6.1.4.1.9.9.64.1.1.1.1.10
Integer32 (0..120) · seconds
This is the initial digit timeout that indicates the amount of time the managed system waits for an initial input digit from the caller. The timer is activated when the call is accepted and is deactivated upon digit input. If the timer expires, the caller is signaled through the appropriate tone and the call is abandoned. The value of zero disables the timer. The default value of this object is 10 seconds.
cvIfCfgInterDigitTimeOut
1.3.6.1.4.1.9.9.64.1.1.1.1.11
Integer32 (0..120) · seconds
This is the inter-digit timeout that indicates the amount of time the managed system waits for a subsequent input digit from the caller. The timer is started upon receipt of an input digit and restarted as each digit is received until the destination address is identified. If the timer expires and no destination address is identified, the caller is signaled through the appropriate tone and the call is abandoned. The value of zero disables the timer. The default value of this object is 10 seconds.
cvIfCfgRegionalTone
1.3.6.1.4.1.9.9.64.1.1.1.1.12
CountryCodeRepresents a case-insensitive 2-letter country code taken from ISO-3166. Unrecognized countries are represented as empty string. SIZE (0 | 2) · OCTET STRING
This object contains the country specific setting for the tone, ring, cadence parameters to be used by this interface.
The object specifies the worst case Echo Return Loss for which the echo canceller must operate. To some echo cancellers this object may not apply. This object is valid if the cvIfCfgEchoCancelEnable object is 'true'. echoCancellerWorstERL6dB - 6 decibels worst case ERL. echoCancellerWorstERL3dB - 3 decibels worst case ERL. echoCancellerWorstERL0dB - 0 decibels worst case ERL. echoCancellerWorstERLUnknown - the object does not apply to this echo canceller. The default value of this object is echoCancellerWorstERL6dB unless echoCancellerWorstERLUnknown is appropriate because the echo canceller is not configurable by this object.
The object specifies which echo canceller is present on the interface. echoCancellerStandard - for this echo canceller valid values of cvIfCfgEchoCancelCoverage are echoCanceller8ms through echoCanceller32ms; cvIfCfgEchoCancelWorstERL is not valid. echoCancellerExtended - for this echo canceller valid values of cvIfCfgEchoCancelCoverage are echoCanceller24ms through echoCanceller128ms; cvIfCfgEchoCancelWorstERL is valid.
