The Allied Telesis AT-210TS is a slim-line media attachment unit (MAU) that bridges AUI ports to 10Base-T twisted pair cabling. This compact external transceiver enables 10 Mbps Ethernet connectivity over standard UTP media at distances up to 100 meters, making it ideal for extending network reach in space-constrained environments.

– Key Features
• Link Integrity Test Function with LED indicator provides continuous connection verification to the multiport repeater; transmission is inhibited and the Link LED extinguishes upon test pulse failure
• Polarity Detection and Correction automatically reverses receive pair polarity in less than one second; Polarity indicator remains off when pair transposition occurs
• SQE/Heartbeat Test function switchable via externally accessible control
• Jabber Lock-up Prevention integral circuitry prevents continuous transmission errors
• Loopback Function emulates coaxial media for MAU connection and operational status verification by LAN controllers
– Typical Applications
Direct connection to workstations and network nodes requiring AUI-to-twisted pair media conversion in 10 Mbps Ethernet installations where space constraints demand compact transceiver form factors.
– Compatibility & Integration
The AT-210TS integrates into existing infrastructures through its DB15 AUI connector paired with standard RJ-45 termination, supporting legacy 10Base-T network architectures compliant with IEEE 802.3 standards.
