The DSU III S2W incorporates advanced features utilizing microprocessor and VLSI technology in a standalone package. Using the Northern Telecom T-Link® rate adaption protocol and time compression multiplexing (TCM), the DSU III S2W transports customer synchronous (up to 64 kbps) or asynchronous (up to 57.6 kbps) data over a 2-wire local loop to the network. Both EIA-232 and V.35 DTE interfaces are provided for all data rates. The DSU III S2W supports manual (invoking a stored number or keypad) or automatic dialing. DTE interface dialing is supported by use of AT commands or V.25 bis in-band dialing. A separate DB-25 connector is provided for EIA-366 parallel dialing or out-of-band AT dialing. The unit responds to standard loopback commands from the service provider and provides extensive test capabilities. Tests include DTE, DTE and loop, DTE with test pattern, and loop only. The front panel of the standalone DSU III S2W contains a two-line by 16-character LCD display and seven LEDs. The front panel keypad operates a simple menu structure which accesses setup, selection of test modes, local configuration, and manual or automatic dialing from stored numbers. Configuration is also available by using the AT command set. DSU III S2W DSU III S2W BBS Ethernet LAN n PC Adíratí Aduratî DSU III S2W ADTRAN, Inc.
