1 General Overview
The DM-1000-4 Digital Station is a narrowband repeater specifically designed for
DV/IP format digital transmissions used on the i2way Network. The station
receives i2way Network signals on one frequency, decodes, processes, reformats
the data, and rebroadcasts it on another frequency. i2way Network signals
contain call control information, streaming digital voice and customer payload
data. i2way format stations do not respond to or repeat analog transmissions, or
any other form of digital transmission.
The DM-1000 Digital Station is available in various models that cover the
138-520 MHz bands. The station receives and transmits data at 10,000 bps using
four level frequency shift keying (“4FSK”) in 12.5 kHz channels.
The station’s construction is modular, and may be field repaired by simply
replacing plug-in modules. It may be configured in single channel “conventional”
or multi-channel “trunked” modes. Multi-channel systems are typically trunked,
with one channel operating as the “control channel” and the remaining channels
as “transaction channels”.
This manual details the version for 12.5 kHz spaced channels in the 406-470
MHz bands. This station may be used in government and international service
down to 380 MHz.
2 Installation
The DB-1000 station is designed to be installed indoors, typically in an electronic
equipment rack. DWC manufactures equipment cabinets specifically for this
purpose although a large number of commercially available “rack cabinets” are
suitable. The station may also be installed in a specifically-designed “outdoor”
cabinet intended for the housing of sensitive electronic equipment. A trained
technician should perform the installation.
2.1 Unpacking after Shipment Receipt
The station is normally shipped in a cardboard carton protected by foam. The
unit is ready-to-operate, and generally the only included accessories not attached
are the power cord and rack-mounting brackets. If the rear panel power switch is
protected by tape or other method, remove this before operating.
