WARNINGS, CAUTIONS, AND GENERAL NOTES
This product conforms to FCC Part 15. Changes or modifications not expressly
approved by the party responsible for compliance could void the user's authority to
operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.”
In accordance with FCC regulations regarding human exposure to radiofrequency
energy, this device shall be installed such that a minimum separation distance of 20cm
is maintained between it and general population.
The antennas used for this transmitter must not be co-located or operating in conjunction
with any other antenna or transmitter.
This Class B digital apparatus meets all requirements of the Canadian
Interference Causing Equipment Regulations. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
Cet appareillage numérique de la classe B répond à toutes les exigences de
l'interférence canadienne causant des règlements d'équipement. L'opération
est sujette aux deux conditions suivantes: (1) ce dispositif peut ne pas causer
l'interférence nocive, et (2) ce dispositif doit accepter n'importe quelle interférence
reçue, y compris l'interférence qui peut causer l'opération peu désirée.

1 System Description
1.1 Introduction
The DATA-20 is a spectrum-scalable point-to-point digital radio that can deliver 8Mbps of data.
Advanced modulation and digital processing techniques allow one radio to deliver user-defined
rates from 512 kbps to 8Mbps
The product is an all-digital, open-architecture, modular system (see Figure 1-1 below). The
versatility and power of the product comes from a complete range of “plug and play” personality
modules.
Figure 1-1. DATA-20 Modular Open Architecture
The high spectral efficiency of the DATA-20 is achieved by user-selectable QPSK, or 16 QAM.
Powerful Reed-Solomon error correction, coupled with a 20-tap adaptive equalizer, provides
unsurpassed signal robustness in hostile RF environments.
1.2 System Features
Selectable Rates: 512 kbps to 8.448 Mbps
Selectable Spectral Efficiency of 1.6 or 3.2 bps/Hz
QPSK & QAM Modulation
Powerful Reed-Solomon Error Correction with up to 12 level interleaver
Built-in Adaptive Equalizer
Internal Duplexer or external for hot standby system
Independent Synthesized Tx & Rx units

Data Rate MUX Hardware Channels Interface(s)
1.5 Mbps-8 Mbps 2 or 4 x E1/T1 2 or 4 G.703, E1/T1
512 kbps-2 Mbps QAM Modem 1Fractional E1/T1
512 kbps-2 Mbps QAM Modem 1 V35, RS449
1.3.2 Standalone Operation
The DATA-20 may be used as a standalone digital radio with an interface in the modem or with a
Multiplexer with 2 or 4 E1/T1 interfaces. The Multiplexer has an overhead channel which can be
utilized by the customer

1.4 Regulatory Notices
FCC Part 15 Notice
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at his expense.
Any external data or audio connection to this equipment must use shielded cables.
