NOC-NEM Interface Data Format
Element Management System (EMS) 4.0 User Manual

5.3 Data Format
The NOC-NEM language consists of two types of character strings: “commands”
and “response messages.” Commands are entered by the user to request NOC–
NEM to perform particular actions. Response messages are returned by NOC–
NEM to indicate its response to commands.
Usually, commands and response messages occur on a one-to-one basis, with a
response message returned for each command. In one case, the
POST STATUS
message, NOC–NEM displays a response message without being asked to do so.
POST STATUS messages are displayed automatically at regular intervals if not
turned off by the user.
5.3.1 Command Format
All NOC–NEM commands have common features. Below is an example of a
NOC–NEM command.
DEMS PineIslandTower SET RECORD 30:00
These features include:
• The letters DEMS, which begin every command.
• Use of spaces to separate word-like components or numbers.
• Case-sensitivity, with command name (
SET RECORD) in upper case.
• Parameter values such as, in this example,
30:30, denoting a record
time interval of 30 minutes and 30 seconds.
All commands are entered by pressing the Enter key or equivalent key on the
computer or terminal keypad. The emulation program should send “Line Feed”
(
LF) characters when the enter key is pressed.
5.3.2 Response Message Format
Every NOC-NEM command, when entered, evokes a response message. Below is
an example of a response message for a command that was rejected for some
reason.
