AT-MX10S, AT-MX20T & AT-210TS, Micro Transceivers AT-MX10S, 10Base2 MAU, slim-line transceiver AT-MX20T, 10T MAU transceiver AT-210TS, 10T MAU, slim-line transceiver KEY FEATURES These micro transceivers are 10Base2 and 10T compliant A test pulse is periodically transmitted and expected transceivers designed to reduce Ethernet cabling costs. at the companion transceiver’s receive side. If the IEEE 802.3 compliant Compact size allows these transceivers to connect pulse is not seen on the receive side, the transceiver and Ethernet Version 1.0 directly to the workstation, bringing thin Ethernet is placed into link test fail mode. Normal operation and 2.0 compatible or Unshielded Twisted Pair (UTP) wiring directly of the transmit side is inhibited and the “Link” LED to the workstation. With UTP and inexpensive coax is turned off. Normal operation is resumed when Direct Attachment Unit network media, distances up to 100 meters between the link is reestablished by the reception of a valid Interface (AUI) connection workstations can be supported using UTP, and up to packet or two valid link pulses. 185 meters using coax. Slim-line versions 10T transceivers also address the polarity of the receive (AT-MX10S,AT-210TS) The 10Base2 compliant AT-MX10S transceiver uses pair wiring. In less than one second, the UTP transceiver for improved mechanical an industry-standard Ethernet transceiver chip that automatically “rolls” the wire pair and allows for the fit for Macintosh, guarantees IEEE 802.3 compliance. The 10T compliant proper operation of the transceiver. Also, the “Polarity” Sun SPARC stations AT-MX20T and AT-210TS transceivers are also indicator on the AT-210TS transceiver is not illuminated and IBMRS/6000 guaranteed compliant by the use of standard ICs. when the circuitry has transposed the receive pair. workstations On all models Signal Quality Error (SQE)/Heartbeat SQE/Heartbeat test status is indicated by LEDs on the Switch-selectable SQE test test can easily be enabled or disabled via an externally AT-MX10S, and AT-210TS transceivers. The AT-MX10S (all models) and LED accessible switch. Additionally, all models have integral transceiver utilizes a two-colored LED that indicates the (AT-MX10S,AT-210TS) jabber lock-up prevention circuitry and a loopback presence of Data Terminal Equipment (DTE) power in function. This function emulates coaxial media where addition to the SQE test. The AT-210TS has a single LED Polarity detection transmitted packets are looped back to the receive side. that indicates the status of the SQE test switch. and correction Local Area Network (LAN) controllers can use the loop- (AT-MX20T,AT-210TS) back feature to determine if a Media Attachment Unit and LED (AT-210TS) (MAU) is connected and operational. Link integrity test The AT-MX20T and AT-210TS transceivers incorporate function and LED other functions that offer improved network reliability (AT-MX20T,AT-210TS) for workstations. The 10T link integrity test function provides a continuous test of the connection to the ABOUT ALLIED TELESYN 5 year warranty multiport repeater.
