About the DSU

Model 7612 SNMP DSU Features
1
NMS
LAN A
Router
The Model 7612 SNMP DSU provides an interface between the customer premises equipment (CPE) and a DDS network. Its features include:
Integral LAN Adapter. Connects the DSU directly to an Ethernet LAN. 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.
ASCII 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.

About the DSU
Remote Management. Provides remote management:
— Using an external modem through the Terminal port — Using SNMP or Telnet through the 10BaseT port or the IMC
DDS Operation. Operates at 56 kbps and 64 kbps CC (clear channel). LADS (Local Area Data Set) Operation. Operates as a limited-distance
modem at 56 kbps and 64 kbps full-duplex.
Autorating of Line Rate. Establishes the line rate from the network receive
signal and automatically adjusts to the detected line rate.
Data Port Rates. Automatically adjusts to the DDS or LADS operating rates. 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 help prevent
unauthorized access to the DSU.

About the DSU
SNMP Management Capabilities
The DSU supports SNMP Version 1, and can be managed by any industry-standard SNMP manager and accessed using SNMP by external SNMP managers.
Management Information Base (MIB) Support
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 the synchronous data port on the DSU.
Ethernet-like MIB (RFC 1643) – Defines objects for managing Ethernet-like
interfaces (e.g., 10BaseT).
Enterprise MIB – Supports configuration, status, statistics, and tests.
Rear Panel Interface Connections

Using the ASCII Terminal Interface

Accessing the ATI
You can communicate with the ASCII 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 10BaseT port.
2
Telnet session through the In-band Management Channel (IMC).
NOTE:
Only one ATI 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 Table A-5, Terminal Port Options, and Table A-6, Telnet Session Options.
The user interface is idle 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 Chapter 4,
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.

Overview
4
The DSU provides several ways to control access to the ATI through option settings. You can:
Enable the Login Required option to require a Login ID for the:
— Terminal Port — Telnet Session via the IP interfaces (the 10BaseT port or the IMC)
Limit the access using:
— Port Access Level option of 1, 2, or 3 for the Terminal port — Session Access Level option of 1, 2 or 3 for the Telnet Session
Refer to Table 4-1, Effective Access Levels.
Disable the access using:
— In-Band Management Channel Rate (bps) option for the IMC — Ethernet Port Use option — Telnet Session option
Refer to SNMP security is handled through Community Names with access levels and
IP address validation. Refer to Preventing access to the ATI by setting the In-Band Management Channel Rate
or Ethernet Port Use options to Disable also inhibits SNMP management over those interfaces.
