About the SNMP DSU
Model 7610 SNMP DSU Features
The SNMP DSU provides an interface between the customer premises
equipment (CPE) and a DDS network. Its features include:
SNMP (Simple Network Management Protocol) Management. Provides
network management via an industry-standard SNMP management system.
In-band Management Channel (IMC). Provides remote management via
SNMP or Telnet session capability over the DDS network.
1
Async Terminal Interface (ATI). Provides a menu-driven VT100-compatible
interface for configuring and managing the DSU locally or remotely by Telnet
session or External Modem.
Local Management. Provides local management via an:
— Async terminal connection through the Terminal port
— NMS connection through the Management port
Remote Management. Provides remote management:
— Out-of-band, using an external modem through the Terminal port or
Management port
— Via Telnet through the Management port or the In-band Management
Channel (IMC)
DDS Rates. Operates at 56 and 64 kbps CC (clear channel).
LADS Operation (Local Area Data Set). Operates at 56 and 64 kbps
full-duplex (also called a limited distance modem).
Autorating of Line Rate. Establishes the line rate from the network receive
signal and automatically adjusts to the detected line rate.
Data Port Rates. Supports the same rates as the DDS or LADS operating
rates, except when the IMC is enabled.

Diagnostics. Provides the capability to diagnose device and network
problems and perform tests, including digital loopbacks, pattern tests, and
self-test.
Device and Test Monitoring. Provides the capability of tracking and
evaluating the unit’s operation, including health and status, and error-rate
monitoring.
Two Customer-Specified Configuration Storage Areas. Allows quick
access to alternate sets of configuration options.
Security. Provides multiple levels of security, which prevents unauthorized
access to the DSU.
SNMP Management Capabilities
The DSU supports SNMP Version 1, and has the capability of being managed by
any industry-standard SNMP manager and accessed using SNMP protocol by
external SNMP managers.

MIB Support
1-2
The following MIBs are supported:
MIB II (RFC 1213 and RFC 1573) – Defines the general objects for use with
a network management protocol in TCP/IP internets and provides general
information about the DSU. MIB II is backward-compatible with MIB I.
RS-232-Like MIB (RFC 1659) – Defines objects for managing RS-232-type
interfaces (e.g., V.35, RS-422, RS-423, etc.) and supports synchronous data
ports and management communication ports on the DSU.
Enterprise MIB – Supports configuration, status, statistics, and tests on the
DDS network interface.

Supported Link-Layer Protocols
The DSU supports two link-layer protocols for connection to an external SNMP
manager or network device:
Point-to-Point Protocol (PPP)
Serial Line Internet Protocol (SLIP)
Typical SNMP DSU Configurations
The following illustration shows a typical LAN/WAN interconnection application for
the DSU. The routers connected to the DSU at each location provide the LAN
interconnection.

About the SNMP DSU
User Interface Types
There are three types of user interfaces for the SNMP DSU:
Menu-driven async terminal interface screens (see
SNMP NMS Access – Refer to the
the capability to access the DSU via an SNMP management system
connected to the Management port or remotely through the in-band
management channel (IMC) connection. Refer to
Front panel LED status indicators. Refer to
Rear Panel Interface Connections
The following illustration shows the physical interfaces of the DSU. Information

Using the ATI
Accessing the ATI
You can communicate with the Asynchronous Terminal Interface (ATI) using one
of the following methods:
Direct connection through the Terminal port.
Dialing in through an external modem to the Terminal port.
Telnet session through the Management port (locally or via an external
2
modem).
Telnet session through the In-band Management Channel (IMC).
NOTE:
Only one asynchronous user interface session can be active at a time, and
another user’s session cannot be forced to end. To automatically log out a
user due to inactivity, enable the Inactivity Timeout option (see Terminal Port
Options, Table A-4).
The user interface is blank until activated. Press Return to activate the user
interface. Security can limit ATI access several ways. To setup security or a login
ID, refer to
Connecting to the Terminal Port
Verify that the settings of the device that you connect to the Terminal port match
these factory-loaded option default settings:
Data rate set to 9.6 kbps.
Character length set to 8.
Parity set to None.
Stop Bits set to 1.

Configuration option settings determine how the DSU operates. Use the DSU’s
Configuration branch to display or change configuration option settings.
Configuration Option Areas
The DSU is shipped with factory settings in the Default Factory configuration
option area. You can find default information by:
Customizing the SNMP DSU
Referring to
Appendix B.
Accessing the Configuration branch of the DSU menu.
The DSU offers four sets of configuration option settings located in the following
areas. The first three sets match the Default Factory Configuration options set
until modified and saved by the user.
If the factory default settings do not support your network’s configuration,
customize the configuration options for your application.
