Technical Details for Allied Telesyn AT MR121T

Allied Telesyn AT MR121T ... media, including UTP (10BASE-T), thinnet (10BASE2) and thicknet (10BASE5) in any combination of media.
Segments on either side of the unit support full length, fully repeated transmission and allow the maximum number of nodes specified by the IEEE. These micro repeaters utilize state-of-the-art technologies, including a custom Application Specific Integrated Circuit (ASIC) and Surface Mount Technology (SMT), which provide enhanced functionality, increased reliability and improved performance.

The CentreCOM Micro Repeaters provide the complete functionality of large repeaters, including packet regeneration and network partitioning. The packet regeneration results in a higher performance network by regenerating preamble, retiming the data packets and extending collision fragments to ensure collision enforcement by all nodes. The use of a custom ASIC as well as an internal power supply make the CentreCOM Micro Repeaters compact and easy to install. The small size of the units allows for the repeater function to be brought to the desktop or used in a wall mount installation.

The AT-MR121T allows a UTP (10BASE-T) segment to connect to all other Ethernet media.

Network diagnostic LEDs are provided on the front of the CentreCOM Micro Repeaters to aid in troubleshooting and fault isolation. Both segments have "Transmit," "Receive," "On Line" and "Collision" indicators. All units come with a "Power" and a "Link Integrity Test" LED for UTP ports.
