Blocking (BLO)
|
|
Blocking (BLO) message sent only for maintenance purposes to the exchange at
the other end of a circuit, to cause an engaged condition of that circuit for
subsequent calls outgoing from that exchange. When a circuit is used in the
bothway mode of operation, an exchange receiving the blocking message must be
capable of accepting incoming calls on the concerned circuit unless it has
also sent a blocking message. Under certain conditions, a blocking message is
also a proper response to a reset circuit message. |
