This step is optional.
Enter the following information.
Parameter |
Description |
Number of voice ports to configure | Number of voice ports to be configured on this IAD. This is not necessarily the same as the number of voice ports supported on the IAD. If the number of voice ports supported on the IAD is less than this value, the voice ports that cannot be supported are alarmed. During creation, when this field is set, the system automatically creates the configured number of IAD Voice Port objects, which exist until the IAD Port is destroyed. If this field is later modified, the system creates or deletes IAD Voice Port objects correspondingly. |
Maximum concurrent calls allowed | Maximum number of calls that can be in progress at any one time on the IAD. This value allows you to restrict the amount of bandwidth used on the VCC to the IAD, on the assumption that not all voice ports on the IAD will need to be in use at the same time. This count includes both ADPCM (G.726) and PCM (G.711) calls. For the purposes of this count, if a tone (such as the reorder tone) is being played to a subscriber outside of a call, the subscriber is viewed as being in a call for the duration of the tone. If a call setup attempt is made to or from the IAD after this count has been reached, the call setup attempt will be rejected. This value cannot exceed the value of Number of voice ports to configure for this IAD. |
Maximum concurrent PCM calls allowed | Maximum number of PCM (G.711) calls that can be in progress at any one time on the IAD. This value allows you to restrict the amount of bandwidth used on the VCC to the IAD, on the assumption that not all voice ports on the IAD will need to be in use at the same time. For the purposes of this count, if a tone (such as the reorder tone) is being played to a subscriber outside of a call, the subscriber is viewed as being in a call for the duration of the tone. If a PCM call setup attempt is made to or from the IAD after this count has been reached, the call setup attempt will be rejected. This value cannot exceed the value of Maximum concurrent calls allowed for this IAD. If the IAD supports only PCM and not ADPCM (AAL2 channel profile is set to Profile 9), the two values should be the same. |
Cell delay variation | The cell delay variation in milliseconds for terminations using this IAD. This value is used to help cancel out variation in the arrival rate of voice data cells from the IAD. (This variation is also known as jitter.) Larger values may improve quality, especially for modem and fax, but will add a small delay to the voice data received from the IAD. Note that increasing this value allocates extra resources on the ATM adaptor and frequent use of values greater than 16ms may reduce the total concurrent call capacity. Range: 1 - 60. |
Deactivation mode | Specifies how child objects should be deactivated when deactivating this object. Values:
|
AAL2 channel profile | Specifies which AAL2 profile is used for AAL2 channels used by this IAD. Values:
|
