The KEYMILE 37853406 is a LineRunner SHDSL-1 DTM AC desktop modem, part of Keymile's LineRunner SHDSL LCM/DTM system — a modular SHDSL transmission platform for effective provisioning of TDM data services. It uses single-pair SHDSL (Single-Pair High-Speed Digital Subscriber Line) transmission technology per ITU-T G.991.2, delivering symmetrical data services over a single copper pair. This DTM (desktop) unit is supplied with a built-in G.703/G.704 (120 ohm) user interface and can be fitted with additional application interfaces via optional pluggable rear modules. It can be flexibly configured as NT (Network Termination) or LT (Line Termination), and supports remote power feeding to regenerators or other desktop units over the transmission path. Fully compatible with Keymile's UMUX multi-service access platform and the IP-MSAN MileGate, and supervised via Keymile's LineRunner ASMOS management software. This "AC" variant is mains-powered (98–264VAC), unlike the DC (48VDC) variant seen in other LineRunner models.
