ALLIED TELESYN MICRO TRANSCEIVER AT-210TS-05D

The CentreCOM Micro Transceivers are 10Base-2 and 10Base-T (AT-210 T, AT-210 TS) compliant transceivers designed to reduce Ethernet cabling costs. Compact size allows these transceivers to connect directly to the workstation, bringing thin Ethernet or Unshielded Twisted Pair (UTP) wiring directly to the workstation. With UTP and inexpensive coax network media, distances up to 100 meters between work-stations can be supported using UTP, and up to 185 meters using coax.

The AT-MX20T, AT-210T and AT-210TS transceivers incorporate other functions that offer improved network reliability for workstations.

A test pulse is periodically transmitted and expected at the companion transceiver’s receive side. If the pulse is not seen on the receive side, the transceiver is placed into link test fail mode. Normal operation of the transmit side is inhibited and the

“Link” LED is turned off. Normal operation is resumed when the link is re-established by the reception of a valid packet or two valid link pulses.

10Base-T transceivers also address the polarity of the receive pair wiring. In less than one second, the UTP transceiver automatically “rolls” the wire pair and allows for the proper operation of the transceiver. Also, the “Polarity” indicator on the AT-210T and AT-210TS transceivers is not illuminated when the circuitry has transposed the receive pair.

SQE/Heartbeat test status is indicated by LEDs on the AT-MX10, AT-MX10S,

AT-210T and AT-210TS transceivers. The AT-210T and AT-210TS both have a single LED that indicates the status of the SQE test switch.
