A method performed by an element manager, the method comprising: determining that a first alarm notification of a first format, received from a wireless local area network access point includes an ifOperStatus object set to indicate that an operational status of an interface associated with the wireless local area network access point is down; determining that the first alarm notification does not correspond to an active alarm in an alarm list stored at the element manager; generating, by an integration reference point agent located at the element manager, based on the determination that the first alarm notification includes an ifOperStatus object set to indicate that the operational status of the interface associated with the wireless local area network access point is down and determination that the first alarm notification does not correspond to an active alarm, a second alarm notification of a second format to be used by an integration reference point manager of a cellular network, the second alarm notification having a notification type of notifyNewAlarm to notify the integration reference point manager of the cellular network of a new alarm; an alarm type of Communications Alarm to indicate a type of the new alarm; and a probable cause indication to qualify the new alarm and provide information in addition to information provided by the alarm type; and transmitting, by the integration reference point agent, the second alarm notification to the integration reference point manager over a Type-2 interface, wherein the second alarm notification comprises an alarm notification in a 3 rd Generation Partnership Project format; determining, by the integration reference point agent, the first alarm notification is equal to an active alarm in the alarm list stored at the element manager; determining, by the integration reference point agent, whether the ifOperStatus object is equal to down; determining, by the integration reference point agent, in response to the determination that the ifOperStatus object is not equal to down, whether the ifOperStatus is equal to lowerLayerDown; updating, by the integration reference point agent, in response to the determination that the ifOperStatus object is equal to lowerLayerDown, an alarm information in the alarm list; generating by the integration reference point agent, in response to the determination that the ifOperStatus object is equal to lowerLayerDown, a notifyChangedAlarm notification having an object instance that indicates an identity of the wireless local area network access point, a probable cause, a perceived severity, and an alarm type; and transmitting, by the integration reference point agent, a notifyChangedAlarm notification to the integration reference point manager. determining that a first alarm notification of a first format, received from a wireless local area network access point includes an ifOperStatus object set to indicate that an operational status of an interface associated with the wireless local area network access point is down;
