SHDTU03b-31T 2/4-Wire G.SHDSL.bis TDM (E1/T1, V.35, LAN) NTU
In one device, the SHDTU03b-31T offers three DTE I/Fs (E1/T1, V.35, and Ethernet), which can work simultaneously to share DSL bandwidth. The user-configurable interfaces provide flexible application for various service connections. The modem supports two different connectors for G.703 E1/T1 applications (balanced 120 Ohm E1 or 100 Ohm T1 RJ45, unbalanced 75 Ohm dual BNCs) at bit rates from 64kbps to 2.048Mbps. The V.35 interface provides high-speed TDM services by way of a DB25 I/F and adapter cable. The factory selected RS-530 interface will electrically support RS-530, X.21and RS-449 with appropriate adapter cable. The data rate of DB25 I/F may be up to 5.7Mbps within one pair copper wires or 11.4Mbps within two pairs copper wires. The modem provides 10/100Mbps auto-negotiated Fast Ethernet via an RJ45 LAN connector, which offers customer premise high-speed LAN over TDM services. The SHDTU03b-31T can be configured and managed via LCD, or menu-driven VT100 compatible asynchronous terminal Interface, either locally or remotely.
