How to Send Text
String to Remote Sites
from the Hub. Use the Service Message option to send a message or a command from the Operator Workstation to
the remote node terminal, and directly to the node. The message can be up to 28 characters in
length.
All commands issued to a remote node shall begin with a prefix of "IDC>". Refer to the IDC-150
Network Control Modem Operation and Maintenance Manual for a complete listing of all commands
supported. The purpose of this option is to allow simple, text-based communication between the
remote node and the operator and to provide the operator with remote command capability.
Any text string of up to 28 characters that can be accepted from the remote node terminal through the
user port can be sent as a service message. The operator can send such commands to a remote
node for configuration or call requests. All service messages from the remote node to the NMS are
displayed in the Event Log and sent out by SNMP traps. Similarly, all responses for commands
originating from the Operator Workstation are displayed in the Event Log.
Under “MidasOID.maintenance.serviceMessage” (.1.3.6.1.4.1.6247.2.7.1), object “toNode” is the
node, which the text string is sent. Object “OutStr” is the text string sent to remote node and is limited
less than 28 characters. When object “send” is set true (2), the text string in object “outStr” will be
sent to remote node which is defined in object “toNode”.
How to Receive Text
String from Remote
Sites Any text string (less than 28 characters) sent by remote sites will be received by the hub and sent
out by the trap.
The customer system can receive text string from remote sites by configurating MIDAS to send a
trap. In MIDAS trap type 2 (Midas value change trap), the first object in variable list of trap defines
the remote node which is sending the text string, the second object in variable list of trap defines
text string sent by remote node. Object ID of the first object in trap type 2 shall be
“MidasOID.maintenance.serviceMessage.toNode” (.1.3.6.1.4.1.6247.2.7.1.1).
