Description
The DDS All Rate is a universal rate data service unit (DSU) for remote site
locations in digital networks. It supports all standard
subrates and both 56 and 64 Kbps (clear channel) high speed rates. Designed for
easy “plug-and-play” operation, the DDS All Rate simplifies both initial
installation and any future service upgrades. This highly reliable, feature
packed product combines superior performance with a sleek, compact design that
is perfect for any remote or satellite office environment.
Easy Installation and Maintenance
The DDS All Rate is configured using simple, clearly marked switches on the
bottom of the unit. The optioning information is contained in a chart placed
next to the option switches. In fact, this DSU will automatically detect
an incorrectly wired line connection and internally correct the connection.
There is no need to wrestle with complicated prompts or confusing menu trees, or
plow through a detailed instruction manual. The unit can be preconfigured and
then delivered to a remote site for plug-in installation.
Automatic Rate Selection Service upgrades are virtually transparent to the user
— including upgrades between subrates and from subrate to 56/64 Kbps operation.
The unit automatically adjusts its operating rate to match the incoming signal
and selects the appropriate V.35 or EIA/TIA-232E interface. There are no bulky,
expensive adapter cables to buy and no need to change the unit’s internal
printed circuit board.
Powerful Diagnostics
The DDS All Rate includes a variety of features to ensure that system faults are
quickly isolated and resolved. First, the unit can determine whether or not the
transmit and receive wire pairs of the digital facility have been transposed.
This feature alone prevents wasted troubleshooting hours. Another unique
capability is the Error Free Seconds (EFS) test, which can be set to run
automatically (e.g., overnight). This allows the user to confirm that the
service is performing within telephone company specifications.
The DDS All Rate also features three
different Remote Digital Loopback (RDL) tests, ensuring diagnostic compatibility
with many other standards-based DSUs. Tests are initiated via dedicated front
panel push buttons, and the results are shown in an easy-to-read Electronic
Display Window.
Superior Performance
The DDS All Rate includes GDC’s Extended Dynamic Range feature that assures
trouble-free operation, even over lines with very low signal levels, such as
unusually long subscriber loops. In 64 Kbps clear channel operation, an
anti-lockup feature protects against remote CSU/DSU lockup in permanent loopback
— a condition caused by data signals that look like in-band loopback
command codes. The DDS All Rate incorporates powerful VLSI and
microprocessor technology, so it consumes very little power, resulting in low
heat dissipation and longer component life for many years of reliable
performance.
