The Loop-AM3440-A/B/C series are Access DCS-MUXs that combine various digital access interfaces into E1 or T1 lines for convenient transport and switching. The Loop-AM3440 Access DCS-MUX provides access for a variety of TDM, IP, and voice interfaces. These interfaces are compatible with other Loop products. Using these
products, a DTE interface can be extended over copper wire pairs or any E1/T1 transport facility. Each Quad E1/T1 plug-in card can have as many as DS0 124/96 time slots from G.SHDSL, RS232, X.21, V.35, V.36 and EIA530 / RS449 interfaces, which can be multiplexed to fill 4 E1/T1 lines. The AM3440 also supports fiber optical plug-in cards, which can be used to aggregate up to 4 E1 channels onto a single fiber optical interface to connect with other AM3440 devices or with the O9310-E1.
