4.4  System Configuration 

The System Configuration screen provides access to most 2361 modem configuration options. To 
access it, type "1" from the Main Menu. The System Configuration screen will appear. Table 3 
details some of the main features of each System Configuration submenu.  
 

 

 

Figure 25. The System Configuration Screen 

 
 

 

Table 3: System Configuration Option Definitions 

 

Hardware Configuration 

Displays the Model, Type, Revision number, and 
Power Supply options for the modem and its 
ELIMs and OLIMs. Also displays the modem's 
SNMP status, if applicable. 

Functional Configuration 

Provides functional configuration settings for 
Framing Pattern, Line Length and Coding. 

Link Level Trap Configuration 

Enables or disables traps to the customer's 
Network Manager 

AlarmOutput Configuration 

Allows regulation of Major/Minor and On/Off 
conditions for each alarm condition 

SNMP Configuration 

Set up SNMP, if a Network Manager is in use 
(Standalone only) 

 
 
What follows is a suggested order for viewing and configuring the 2361 modem's parameters. 
The screens can actually be accessed and configured in any desired sequence.
