ADC Release 3.1 user manual Nmic Serial Equipment Port, Cellworx STN System Software

functions, or SNMP access for Sets, Gets, Traps etc. Up to five GUI sessions may be launched at a time. An X-Terminal may remain active while the GUI is launched on another terminal. A user establishes a Telnet session to the NMIC to launch the GUI. The NMIC can maintain the Telnet session after the GUI is exited, or maintain the GUI functionality after the user terminates the Telnet session, but once both the Telnet session is terminated and the GUI is exited, the Telnet session must be re-established.

NMICs support 1:1 protection and provide independent Ethernet connections. Each NMIC has a unique IP address and a shared IP address, requiring the administrator to provision each of them on the X-Terminal. If the administrator cannot connect using the shared IP address (NMICs are unobtainable or a no response message is generated from a remote Telnet session connection attempt), the administrator can reattempt the Telnet session utilizing either the working or the protection NMIC IP addresses.

C.NMIC Serial Equipment Port

A serial port is provided on the NMIC EIM that can be used for modem access or other types of serial equipment. This port will provide the same system access as the Ethernet port. It has jumpers that enable the user to strap the port for DTE or DCE depending on the serial device connected to it.

3. CELLWORX STN SYSTEM SOFTWARE

A.NMIC Graphical User Interface (GUI)

The Cellworx NMIC GUI interface provides a simple, consistent means of interaction through menu, mouse, and keyboard driven software configuration options. It is an executable program residing on the NMIC that a user gains access to through an X-Terminal window from the shell command prompt. The GUI retrieves data for the user initiated events via SNMP to the Application Core or by accessing the information stored on its hard disk.

Once connected to the NMIC and logged on to the network, a full network view encompassing each node in the network is displayed on the screen. An example is shown in Figure 1-4. An arrangement of icons representing Cellworx STN nodes reflect the network configuration (if configured) and are color-coded indicating the current alarm state of each node. Table 1-1 describes the color codes of the icons. The NE containing the NMICs is referred to as the Gateway Network Element (GNE) and can be determined at a glance from the yellow text underneath it. All other nodes will have white text.

The fiber connections shown between the nodes will appear green if there are no fiber fragment failures. They will turn orange in the event of a fiber fragment failure indicating a major alarm condition on the link between nodes.
