SAM traffic over IP Independent of BNS Networks
The DT-2020 transforms the embedded base of SAM concentrators into versatile IP-based terminal servers. It connects terminals, modems, and microcomputers to IP-based services on LANs or WANs via existing serial lines, while maintaining all SAM functionality without the need for BNS node equipment.
The DT-2020 is a mediation product which allows re-use of a SAM concentrator (up to 64 ports) on an IP infrastructure without any other BNS equipment. The DT-2020 supports all SAM port options, and is compatible with the mediation function of the DT-4000.
The DT-2020 provides a TELNET over TCP path, or a transparent TCP path, for each user port on the SAM concentrator. These ports may then connect to an arbitrary IP host without an intermediary interface. This is normally the case for Asynchronous protocols. It is also true of Synchronous protocols where the peer host has implemented framing per the appropriate RFCs. For hosts which are not directly compatible with these specifications, the circuit will need to traverse a mediation gateway such as the DT-6061.
The compact DT-2020 is available in both stand-alone and rack-mount versions to fit various space and configuration requirements. The DT-2020 is available as either a 115V/220V AC or 48V DC powered unit.
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 with a device connected to a port on a DT-4000.
A
third port on the DT-2020 connected SAM could be
connected
to a fourth port on the same DT-2020.
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 applications) to be directly supported
by
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. The connection to the
IP network is via a 10BaseT interface.
Trunking speed depends on the particular SAM being used:
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 DT-2020
unit's resident SNMP agent supports a database of predefined SNMP MIB
(Management Information Base) variables as well as SNMP Trap, Set, and
Get operations.
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.
Field
software updates, which can be initiated 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
