The NOC/NEM interface is a command line interface that is presented at an NOC terminal. The

NOC/NEM interface is used for remote control and monitoring operations. The NOC/NEM

interface consists of ASCII text strings that are input as standard SET or GET commands which

are followed by the action or information required. A text string response is received from the

specified system or systems to confirm the requested action or to report the requested

information. Examples of several typical NOC-NEM interface commands and the responses

received are shown in Figure 2-19. The NOC/NEM interface requires only a VT100 terminal/

emulator or a PC-type computer that is loaded with a communication software such as

Procomm Plus. While primarily intended for use at the NOC, the NOC/NEM interface

commands may also be input from the EMS computer.
