be blocked due to the previously sent circuit-group-blocking message.

related to trunks which are not locally blocked.

unblocking-acknowledge indication, received for circuits which are not te be unblocked due to the previously sent circuit-group-unblocking message.

be unblocked due to the previously sent circuit-group-unblocking message.

related to trunks which are locally blocked.

which is not locally blocked.

which is locally blocked.

BLO/MGB or UBL/MGU after five minutes.
