### Connection Number (cvIfCfgConnectionNumber)

This is the full 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.

### Noise VAD Regeneration (cvIfCfgNoiseRegEnable)

Indicates whether the background noise should be played to fill silence gaps if VAD is activated. The default value of this object is enabled.

### Echo Cancellation (cvIfCfgEchoCancelEnable)

Specifies whether the Echo Cancellation is enabled for the interface. The default value of this object is enabled.

### Echo Cancel Coverage (cvIfCfgEchoCancelCoverage)

The object specifies the Echo Canceller coverage for the interface. This object is valid if the cvIfCfgEchoCancelEnable object is “true.” The default value of this object is echoCanceller16ms.

Values of the echo canceller coverage are:

echoCanceller8ms | 8 milliseconds
echoCanceller16ms | 16 milliseconds
echoCanceller24ms | 24 milliseconds
echoCanceller32ms | 32 milliseconds

### In Gain (cvIfCfgInGain)

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.

The value range is -6 to 14 dB.

### Out Attenuation (cvIfCfgOutAttn)

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.

The value range is -6 to 14 dB.

### Music On Hold Threshold (cvIfCfgMusicOnHoldThreshold)

The object specifies the Music On Hold Threshold for the interface. The default value of this object is -38 decibels per milliwatt (dBm).

The value range is -70 to -30 dBm.

### Nonlinear Processing (cvIfCfgNonLinearProcEnable)

Indicates whether the Nonlinear Processing is enabled for the interface. The default value of this object is enabled.

### Regional Tone (cvIfCfgRegionalTone)

The country specific setting for the tone, ring, and cadence parameters to be used by the interface.

Shows the two letter ISO-3166 country code.

Values are:

| Code | Country |  | Code | Country |  | Code | Country
| AR | Argentina |  | IN | India |  | PE | Peru
| AU | Australia |  | ID | Indonesia |  | PH | Philippines
| AT | Austria |  | IE | Ireland |  | PL | Poland
| BE | Belgium |  | IL | Israel |  | PT | Portugal
| BR | Brazil |  | IT | Italy |  | RU | Russian Federation
| CA | Canada |  | JP | Japan |  | SA | Saudi Arabia
| CN | China |  | JO | Jordan |  | SG | Singapore
| CO | Columbia |  | KE | Kenya |  | SK | Slovakia
| CY | Cyprus |  | KR | Korea Republic |  | SI | Slovenia
| CZ | Czech Republic |  | LB | Lebanon |  | ZA | South Africa
| DK | Denmark |  | LU | Luxembourg |  | ES | Spain
| EG | Egypt |  | MY | Malaysia |  | SE | Sweden
| FI | Finland |  | MX | Mexico |  | CH | Switzerland
| FR | France |  | NP | Nepal |  | TW | Taiwan
| DE | Germany |  | NL | Netherlands |  | TH | Thailand
| GH | Ghana |  | NZ | New Zealand |  | TR | Turkey
| GR | Greece |  | NG | Nigeria |  | GB | United Kingdom
| HK | Hong Kong |  | NO | Norway |  | US | United States
| HU | Hungary |  | PK | Pakistan |  | VE | Venezuela
| IS | Iceland |  | PA | Panama |  | ZW | Zimbabwe

Dial Timers

### Initial Dial Time out (cvIfCfgInitialDigitTimeOut)

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 value range is 0 to 120. The default value of this object is 10 seconds.

### Interdigit Dial Time Out (cvIfCfgInterDigitTimeOut)

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 value range is 0 to 120. Default is 10 seconds.

### Outgoing DTMF Digit Duration Timing (cvaIfFXSTimingDigitDuration)

Outgoing DTMF digit duration in milliseconds.

The value range is 50 to 500. Default is 100 milliseconds.

### Outgoing DTMF Interdigit Timing (cvaIfFXSTimingInterDigitDuration)

Outgoing DTMF inter-digit duration in milliseconds.

The value range is 50 to 500. Default is 100 milliseconds.
