Description: If set to off(2), a passive link will stay up after all calls are disconnected. If set to on(1), a passive link will drop and go into DMLOCK (see aiXirbBx25DMlock below) when all the incomming calls are terminated. This object is meaningful only when aiLinkX25LinkMode is set to passive(2) on a given link

What is aiXirbBx25CallDown?

Controls the behavior of a passive X.25 link when all incoming calls are terminated: when set to on(1), the link drops and enters a DMLOCK lockout period; when set to off(2), the link stays up waiting for new calls. This setting only applies when the link is configured in passive mode.
