ATLAS 550 1200305L2 multi-T1 IAD, 1/0 DACS, NxT1 Inverse Multiplexer, ISDN switch, IP router, and Frame Relay

Adtran ATLAS 550 Multi T1 mux

In point-to-point applications, an ATLAS IAD converges voice, data, and video onto a common circuit, reducing line costs and simplifying overall network operation and management.

Here, an ATLAS 890 supports up to T3 bandwidth between headquarters and the network cloud. Serving as a circuit switch, ATLAS 890 dynamically allocates shared bandwidth between applications depending on load, significantly reducing the number of digital trunks required to support communications from multiple remotes.

Voice is groomed and transported to the PBX. Data may be transported directly to the LAN (integral 10/100BaseT port and internal IP routing software) or to an external router or other serial device (V.35, EIA-232, EIA-530, RS-449, X.21, and V.36). The ATLAS 550 offers similar functionality for up to four T1s of capacity.
