hh:mm:ss Message No: name:ss,nnnn chars, nnn segments
hh:mm:ss ROUTING name :sss TXT sss/nn TO: name
Messages are transmitted in packets and are routed to their destination in a store and forward
manner, using the most efficient routing within the packet switched network. The originating
station will receive an acknowledgement (ACK) if the message has been received successfully
by the first routing station.
mm/dd/yy hh:mm:ss TXTMSG ACK name:sss, xxxx CHARS FROM name
When the entire message has been delivered to its final destination an end-to-end
acknowledgement will be displayed on the operator terminal:
hh:mm:ss END-TO-END ACK OF name:sss FROM name
If the end-to-end ACK is not received within the specified time-to-live limit, the MCC-545C will
purge the message from the Tx Queue and display the following message:
hh:mm:ss MESSAGE TIME-TO-LIVE EXPIRED, MSG.NO:sss, DESTN: name
You must then reenter the message. Continued failure to successfully transmit a message
indicates that something may be wrong with the equipment or the link (e.g., excessive noise
interference).
4.3.4 Sending Commands
Commands may be sent to any remote station within the network. The entry of a command is
similar to the MESSAGE command described in Section 4.3.1.
REMCMD, R, dest1, dest2, …destn
where: R = priority level
dest = numerical ID of destination station(s)
The operator is then prompted to enter the text of the command using the message editor. Once
the command is entered, press the [ESC] key to send the command. The operator terminal will
display:
A response will be received from the destination station(s) if it was successfully received.
