Media Gateway LAPD Resource

The Media Gateway LAPD Resource object defines the resources on a PB3000 Adaptor that support signaling for ISDN connections.

Each Media Gateway LAPD Resource object is a child of an Adaptor object with adaptor type PB3000, PB3100, PB4000, PB4500 or PB5000.

In the EMS System Explorer, the name shown for each Media Gateway LAPD Resource indicates

For example, LAPD Resource (Controller B, Slot 3, Port 20) "LAP/02/03/20".

In general, you will add Media Gateway LAPD Resource objects using the "create all ports" action on the parent Adaptor object, and should not need to create them individually.

To start using a LAPD Resource, you simply need to enable the resource using the Enable button if it is disabled, and then activate it using the Activate button. You should also ensure that the owning adaptor card is active.


Parameter

Access

Description
Port name Read only A unique identifier for this device among all other devices on the Media Gateway. This identifier is used by other objects that need to reference this device.
LAPD Resource number Create An identifier for this LAPD Resource. The valid resource numbers depend on the parent adaptor type, as follows.
  • A PB3000 adaptor has two child LAPD resources, with resource numbers 19 (used by DS1 ports 1 - 8 on this adaptor) and 20 (used by DS1 ports 9 - 16).
  • A PB3100, PB4000, PB4500 or PB5000 adaptor has one child LAPD Resource, with resource number 5.
Description Read only Information about the controller, chassis slot number and port number associated with this port.
Deactivation mode Change Specifies how child objects should be deactivated when deactivating this object. Values:
  • Normal (default)
    Shut down child objects normally before deactivating the object.
  • Quiesce
    Deactivating the LAPD resource in quiesce mode will wait for all existing users of the port (typically PRI interfaces) to be deactivated, which typically requires administrator intervention. No new users will be accepted for this port during this deactivation period.
  • Abort
    Deactivate the object and all its child objects immediately. (This may result in errors at remote systems.)
IP address Read only The IP address used by SCTP to access this resource.
SCTP port Read only The IP port number used by SCTP to access this resource.
Number of SCTP streams available Read only The number of SCTP streams available on this resource to support ISDN connections.
Requested status Read only Specifies whether an administrator has attempted to activate the LAPD Resource. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
  • Disabled
    The object has been disabled.
Actual status Read only Specifies the current status of the LAPD Resource. Values:
  • Active
    The object is active.
  • Activating
    Activation is in progress.
  • Deactivating
    Deactivation is in progress.
  • Inactive
    The object is inactive.
  • Disabled
    The object has been disabled.
  • Activation Failed
    The object is inactive because an activation attempt has failed.
  • Failed
    The object was active but has failed.
  • Quiescing
    The object is preparing for normal deactivation. It is operating normally but will not accept any new users.
  • Waiting For Parent
    The object cannot be used because its parent object is not yet active.
  • Parent Failed
    The object cannot be used because its parent object has failed.
