BLACK BOX MT190A 64K CSU/DSU
The BLACK BOX MT190A Smart 64K CSU/DSUs are advanced channel service units/data service units that use Digital Signal Processor technology. They’re standalone units that connect two remote locations together to form a wide-area network (WAN). The BLACK BOX MT190A operates in point-to-point or multipoint environments on Dataphone Digi-tal Service (DDS) provided by common carriers.
The BLACK BOX MT190A multirate-line digital termination units operate at all common speeds between 2400 bps and 64 kbps. The line speed and the DTE speed may be the same or different. The CSU/DSUs support both asynchronous and synchronous operation. The BLACK BOX MT190A rear panels have one DB25 DTE connector for RS-232 devices (labeled Port 1), one M/34 DTE connector for V.35 devices (labeled V.35 Port 1), a power connection receptacle, and an RJ-48S female network connect-operation is also available; one BLACK BOX MT190A is configured with a master clock setting. At 56 kbps, depend-ing upon wire gauge, the units can operate error-free up to 10 miles (16.1 km) away.
The BLACK BOX MT190A CSU/DSUs have three front-panel touchpad buttons (Select, Advance, and Enter) to help you easily manipulate the units through port and line settings, diagnostic testing, and selecting an operational display. An LCD display next to the buttons provides a visual interface into the BLACK BOX MT190A CSU/DSUs’ menu system as well as their operation. The LCD dis-play is a single-line, 16-character position display. All defined line speeds that have DTE port speeds less than or equal to the line speed will match each other.
One exception exists for 57-kbps asynchronous operation, which is supported on a 56-kbps DDS facility. In addition, synchronous as well as asynchronous character formats operation is also available; BLACK BOX MT190A unit is configured with a master clock setting.
