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.
Figure 1-5. Direct SLIP

Modem Features 1-5
Modem Features
33.6 Kbps Connections
In addition to supporting normal connect speeds under V.34, V.FC,
V.32 terbo, V.32 bis and older ITU-T standards, the modems in the
MP/16 can connect at 31.2 Kbps and 33.6 Kbps when connecting
with other U.S. Robotics modems with 33.6 Kbps capability.
Custom Power-on/Reset Defaults
Custom configurations can be stored as power-on/reset defaults in
the modem’s Non-Volatile Random Access Memory (NVRAM).
Software Upgrades
Flash ROM make the modems software upgradable.
Fax Capability
Supports Class 1 or Class 2.0 facsimile software and the V.17 fax
protocol.
Link Security
Link Security prevents unauthorized access at the modem level—
before allowing any type of network connection.
Optional Cellular
If you purchased the MP/16 with cellular, the modems can answer
calls across cellular links using ETC and MNP10.
