The L1 variant is described as a spare controller card that includes DS3 support and 28 DSX-1 interfaces, enabling DS3\/T3-level service integration within the MX2800. In MX2800 deployments, two controller cards (A and B) provide 1:1 redundancy to protect against controller-card failure and allow seamless failover. This card handles DS3 and DSX-1 traffic as part of the M13 multiplexer’s TDM service path, supporting DS3\/STS-1 over a T3 interface.\u003c\/p\u003e\u003c\/div\u003e","brand":"ADTRAN","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657022603566,"sku":null,"price":283.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bb220a8d-48ef-46ef-8a7c-1e0fcd1d78cf.jpg?v=1769465279","url":"https:\/\/plgautomation.com\/products\/adtran-1205288l1-m3c3fdwatd-controller-card-module","provider":"PLG Automation ","version":"1.0","type":"link"}
