IAD Voice Port

Each IAD Voice Port object is a child of an IAD object.

The IAD Voice Port object contains configuration parameters for a voice port on an IAD connected to the VP3000. The system automatically creates the configured number of IAD Voice Port objects when the Number of voice ports to configure field of the parent IAD object is set. If the value of this field is later modified, the system creates or deletes IAD Voice Port objects correspondingly. Otherwise, IAD Voice Ports exist until the parent IAD Port is destroyed.

The fields prefixed by (*) are present only if the parent IAD supports a LES EOC channel and are read from the IAD. Note that these fields are not dynamically updated; to refresh the information displayed by these fields, click on the Refresh pushbutton. You should not expect these fields to be updated immediately upon clicking on this pushbutton; a request is sent to the IAD and the fields are updated when the information is returned from the IAD.

Object-Specific Actions

Parameter

Access

Description
Connectivity status Read only Indicates the connectivity state of the voice port. Values:
  • Not specified
    The state of the voice port is not specified.
  • Inactive
    The voice port is not actively connected to another voice port. It may still be in a call or associated with a mix-point for a three-way call. Tones can be played and events can be detected.
  • Loopback
    The voice point is in loopback mode. The data received on this voice port is returned on the same voice port. This allows the remote end to perform continuity testing. This state is valid whether the termination is associated with a call or mix-point for a three-way call.
  • Only send data
    The voice port can send data but not receive data. This state is valid whether the termination is associated with a call or mix-point for a three-way call.
  • Only receive data
    The voice port can receive data but not send data. This state is valid whether the termination is associated with a call or mix-point for a three-way call.
  • Send and receive data
    The voice port can send and receive data. This state is valid whether the termination is associated with a call or mix-point for a three-way call.
Used by Subscriber Read only The directory number of the Subscriber using this voice port. If this field has no value, the subscriber is not enabled, or there is no subscriber using the voice port.
(*) Last refresh time Read only This field is visible only if the parent IAD supports LES EOC. The time at which the information read from the IAD was last refreshed.
(*) Signaling method Read only This field is visible only if the parent IAD supports LES EOC. The signaling method that the voice port has been configured to use. Values:
  • Loop start
  • Ground start
  • Loop reverse battery
  • Unknown
(*) Time active Read only This field is visible only if the parent IAD supports LES EOC. The total length of time that the AAL2 channel has been active, in seconds.
(*) Number of filler octets inserted Read only This field is visible only if the parent IAD supports LES EOC. The number of PCM filled octets injected into active media stream on this AAL2 channel due to playout buffer underflow.
(*) Number of dropped octets Read only This field is visible only if the parent IAD supports LES EOC. The total number of PCM payload octets dropped due to buffer overflow on this AAL2 channel. Octets that are dropped because they arrived late, and which have already been substituted by filled PCM octets are not included.
