Editing My 33.128 Notes (section)

== 5.2	Protocols for LI_X1 and LI_T interfaces ==

=== 5.2.7	Usage for realising LI_XEM1 ===

The IEF shall be enabled by sending the following ActivateTask message from the LIPF.

The <code>IdentityAssociationTargetIdentifier</code> Identifier Type is defined for the use of LI_XEM1. Unless otherwise specified, use of any other Target Identifier Type (including adding a target identifier more than once) shall result in the ActivateTask message being rejected with the appropriate error.

The IEF may be reconfigured to send identity associations to a different ICF using a ModifyTask message to modify the delivery destinations.

The IEF shall be disabled by sending the following DeactivateTask message from the LIPF.

The LIPF should send one ActivateTask command to each IEF.

:NOTE: The IEF may receive multiple ActivateTask messages conforming to LI_XEM1 ActivateTask, each of which can be independently deactivated. The IEF shall remain active as long as at least one valid Task remains active.
