Message Action A Acquisition Failed C Circuit Aborted Denied (Reason) Mismatch Detected Preempted Receive Buffer Overflow Set up Queued (Reason) Set up Rejected (Reason) Table D-4. Messages, 5-kHz DAMA Terminal is not receiving OW. Check azimuth, power out, and reposition antenna. Check previous status messages. If logged out, log in over-the-air. Other messages include circuit not available (especially DASA) and the reason. Attempt to re-establish or establish a different type of service. Circuit service request is denied for the stated reason. If condition is correctable, take appropriate action or try again later. An incoming service is established but a mismatch is detected between the service and the current mode settings. Check setting of PT/CT mode and type of attached data device. The channel controller preempted the circuit. Wait for it to resume before transmitting. Or Contact was temporarily lost with the controller; wait for it to resume. Check data device for incomplete message or errors in message. If needed, request source to retransmit message. Service is queued for the reason supplied. Local—terminal called is logged in but time-slot is unavailable. MHOP—terminal called is not logged in with controller. If it is in another footprint, wait. If it is supposed to be in the current footprint, teardown and try again later. Service request is denied for the stated reason. Try again later unless one of the following reasons is displayed. Data Rate—Requested a DASA service at higher than 2400 bps—no 25-kHz DASA channel available. Not Assignable—The LQ from terminal or the destination terminal is poor. Check LQ in network state menu. If LQ is low, check antenna or raise power. Prec. Violation—The precedence entered is not allowed. Check network state menu for assigned values. Ensure previous messages do not state logged out. If previous message stated logged out, log in over-the-air and re-attempt service set up at lower precedence. Service Restrict—Request for a 2400 bps circuit denied due to network traffic. Reduce data rate or wait until LIO no longer displayed in network state. Terminated (Reason) An existing service is terminated for the stated reason. Try again later. COMMAND Rejected Check parameters and network; try again. Rejected Port is busy (Check Current Mode) Request is rejected because of an existing active service. Ensure terminal is idle before setting up a service. D-9
