About This Guide
This guide covers the following topics:
Chapter 1. Overview. Provides a brief overview of SNMP
management, useful in helping to define SNMP terms used
throughout the manual.
Chapter 2. Installation. Guides you through all the steps necessary
to prepare the MP/16 for management using SNMP. Also
contains information on cabling and configuring the modems
in the MP/16.
Chapter 3. Using Total Control MIBs. Provides information useful
for managing the MP/16 using MIBs. Intended for those who
are not using Total Control Manager/SNMP(TCM) to manage
the MP/16.
Chapter 4. Special Applications. Use to configure the MP/16
modems for such applications as Cellular and Link Security.
This guide assumes that you will be configuring the MP/16
modems through SNMP management. However, two Appendixes
(C and D) provide information on AT commands, which can be
used to configure the modems if so desired.

SNMP Management 1-1
Chapter 1 Overview
SNMP Management
The Simple Network Management Protocol (SNMP) is a widely
supported management protocol that provides remote control and
monitoring of network devices such as the MP/16. The following
figure illustrates the basic components of SNMP management.
Figure 1-1. Basic Components of SNMP Management
SNMP Agent
A special SNMP agentcontained in the MP/16 interprets SNMP
commands and relays them to the managed objects in the MP/16.
Management Station
As a network manager, you are responsible for setting up the
Management Station,a PC running SNMP management software
from which you manage the MP/16 and other devices in your
network.
SNMP Management Software
SNMP management software runs on the Management Station
(MS), and serves as a user interface for issuing SNMP commands to
all managed network devices, including the MP/16.
1-2 Overview
SNMP Commands
There are three SNMP commands: Get, Set, and GetNext. The
Management Station issues SNMP commands to set parameters or
perform other actions on a managed device.
MIBsA Management Information Base (MIB) is a list of objects with
variables that pertain to a particular type of device, such as a
modem. MIBs are necessary when sending or receiving SNMP
information between the Management Station and the MP/16. For
example, the Total Control Modem MIB defines an object for each
modem parameter. When you send a command from TCM to
change a modem setting, TCM references the Modem MIB so that
the command can be properly coded, translated by the MP/16
management module, and applied to the modems. Likewise, when
TCM polls the MP/16 for the status of the modems, TCM uses the
Modem MIB to interpret the SNMP information gathered and
display the correct settings and LED status for each modem.
NOTE: Total Control Manager/SNMP(TCM) is a Windows-based
SNMP management software developed by U.S. Robotics
specifically for Total Control products such as the MP/16. It’s
virtual front panel display and configuration windows provide a
user interface that streamlines management functions. TCM
eliminates the need to deal with MIBs when communicating with
U.S. Robotics Total Control devices.
Applications 1-3
Applications
The MP/16 modem pool integrates sixteen modems for dial-up
access to terminal servers, front-end processors, bulletin boards,
email, or other resources.
Figure 1-2. Typical Setups for Dial-up LAN Access
SNMP management allows you to operate the MP/16, monitor line
activity, and perform dial-up accounting from across a LAN or
WAN (dial-up) connection.
Management from a LAN
The LAN port on the MP/16 allows you to establish an SNMP
connection over a LAN.
Figure 1-3. Management Station on the LAN
1-4 Overview
Dial-up Management
The Console port allows SNMP management over dial-up SLIP
connections from Management Stations in remote locations.
Figure 1-4. Dial-up Management
Direct Management
A local SLIP connection can be made by connecting the
Management Station to the MP/16’s Console port using a standard,
EIA RS-232 connection.
