Purchase of
VertexRSI’s latest generation NSM-20M Nodal Satellite Multiplexer is
now available online
 Government
customers can get product information and order VertexRSI’s Nodal
Satellite Multiplexers through the General Service Administration’s
web site
http://www.gsa.gov
According to Brent Jones, Sales
Manager for VertexRSI, the NSM-20M is among several VertexRSI
communications products featured on the government’s purchasing
site. "Listing our products with the GSA is another way to offer
convenient and fast product technical data and competitive pricing
to national and state government purchasing personnel," Jones said.
"The NSM-20M Generation III Nodal Satellite Multiplexer offers
increased speed and improved performance and versatility. Posting
our product information, purchasing contacts and streamlining the
entire purchasing process just makes sense in today’s e-commerce
market."
The NSM-20M is a small, lightweight
synchronous time-division multiplexer that provides aggregate
interfaces to satellite modems and group interfaces to terrestrial
equipment. The NSM-20M delivers cost-effective solutions to
satellite communication multiplexing demands. In its legacy mode,
the NSM-20M is interoperable with and functionally replaces the
legacy TD-1337 Tactical Satellite Signal Processor (TSSP). In its
enhanced mode, the NSM-20M is interoperable with MIDAS, GMT and
other Mil-Std-188-168 compliant equipment.
Full SATCOM Support
Nathan Knutson, Vice President of Government Strategic Programs
for TriPoint Global Communications, added "Our VertexRSI NSM-20M
provides tactical satellite terminals with capability to work
efficiently in a true ‘Network-Centric’ battle-space. It is designed
and tested for a very high degree of interoperability with existing
equipment and gives the operators a valuable tool to reliably
transport large amounts of data over a network."
The NSM-20M Generation III supports fully connected mesh networks
with up to seven nodes. It multiplexes up to 12 group inputs
(selected in any combination from the 25 ports) into a single
aggregate stream for transmission providing more efficient use of
bandwidth since guardbands between channels are not required. The
unit also features a digital signal processor that performs frame
synchronization acquisition, maintenance, initialization,
configuration, control telemetry, aggregate bit error rate
monitoring and built-in test functions.
Compact Design:
The NSM-20M Generation III is packaged in a single rack unit
enclosure. Packed into that space-saving framework are:
- One multiplexer with one spare
aggregate output
- Six demultiplexers with one
spare demultiplexer switchover input
- 12 active terrestrial-side group
interfaces with satellite Doppler buffers (selected from 25
available ports), and
- A secure/non-secure voice
orderwire bridge with ring detection and generation
User-Friendly:
The NSM-20M Generation III is managed via an EIA RS-232 or RS-485
port connected to a personal computer. A user-friendly graphical M&C
interface provides extensive diagnostic reporting.
