Many
low-end routers available today can handle
2Mbit/s throughput, but they only have conventional
DTE interfaces, usually X.21 or EIA530.
By combining one of these routers with a
MM2048 you get the high performance of 2Mbit/s
without the expense of a higher end router.
The NTU9000 Interface Converter is one of
the most cost competitive solutions for
connecting data communications equipment
to 2.048Mbit/s leased line private circuits.
A derivative of the highly successful MicroMux
SP-1 RA, the MicroMux - G.703 has been engineered
to reduce cost and increase functionality
in this expanding sector of the market.
The NTU9000 comes in two versions. The basic
unit supports X.21, EIA530 and RS449 interfaces,
including support for the external terminal
timing signal on EIA530. The enhanced version
supports V.35 in addition to the above,
and it can be configured either to X.21,
EIA530 and RS449, or to V.35 in the field.
Both versions of the MM2048 support user-configurable
selection for a 75 Ohm unbalanced or 120
Ohm balanced G.703 connection (via dip switches)
. Selection of which type is by way of two
externally accessible switches, and use
of either the BNC connections (unbalanced)
or the RJ45 connection (balanced). The unit
is provided with an internal power supply
and an IEC-connected mains lead to ensure
stability in network critical applications.
