The AT-210TS from Allied Telesyn is a 10Base-T MAU slim line CentreCOM Micro Transceiver designed to reduce Ethernet cabling costs. Its compact size allows this transceiver to connect directly to the workstation, bringing thin Ethernet or Unshielded Twisted Pair (UTP) wiring directly to the workstation. It has integral jabber-lock prevention circuitry, polarity detection and correction, and a loopback function, in addition to easy enabling or disabling of the Signal Quality Error (SQE)/Heartbeat test via an externally accessible switch. It also has four LEDs for easy monitoring of transceiver performance. Solid construction and high quality make this a strong choice for your networking needs.
