About the SNMP DSU

1

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.

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.
