Smart Network Management
The DT-2020 is easy to manage and provides several easy
ways to configure and get status/diagnostic information.
An industry standard Telnet connection to the DT-2020
gives you access to a command line based configuration
application. In addition, a serial RS-232C connection
provides the same configuration capability. Finally, the DT-
2020 is another network element that the StarKeeper® II
NMS can administer, manage, and maintain.
The DT-2020 unit's resident SNMP agent supports a
database of predefined SNMP MIB (Management
Information Base) variables as well as SNMP Trap
operations, Set operations and Get operations.
Field software updates, which can occur from a remote
location, take place while the DT-2020 is in service and
transporting data. As new features and enhancements
come out, the DT-2020 software can be upgraded just
by installing a new software release using an industry
standard Telnet application or serial RS-232C connection
to the DT-2020.The above configuration is not the only
possible one. However, it does depict some of the
interesting interface capabilities of the DT-2020.
The connection to the attached SAM is via a SAM
trunk. For a SAM64, either a SAMSL or a Universal
Trunk is required.Trunking speeds vary on the
particular SAM. A SAM8 supports a 56K trunk, as does
a SAMSL connected SAM64/504.A SAM16 supports a
128Kbit trunk.A SAM with a Universal Trunk supports
link speeds up to E1.The connection to the IP network
is via a 10BaseT interface. The network interface is
active when the DT-2020 is in service even if the
connected SAM is not in service.Other protocols on
the 10BaseT such as SNMP, Telnet, ARP, etc. are not
shown for simplicity of the diagram.
- A port on the DT-2020 connected SAM could be
having a session directly with an IP host.
- A second port on the DT-2020 connected SAM
could be having a session directly with a device sit-
ting off a DT-4000.
- A third port on the DT-2020 connected SAM
could be connected to a fourth port on the same
DT-2020. Local switching is done at the DT-2020
connected SAM (Note:The functionality of the
DT-2020 is built into the DT-4000.)
- A fifth port could be connected to an IP Host via
a mediation application in the DT-6061.This allows
any protocol (even selective broadcast applica-
tions) to be directly supported by the DT-2020.
