means of extending high capacity data systems onto wide area public or
private T3 networks. Supporting a number of interface types including
High Speed Serial Interface (HSSI) and V.35, the DL3100 connects to
bridges, routers, front-end processors and channel extenders.
It can function as a T3 Data Service Unit (DSU) or T3 Feeder Multiplexer.
The DL3100 interfaces up to three DTE Boards (ports) to one T3 facility,
and can be accessed locally or remotely via a dial-up modem or through
the T3 line itself in a ÒmodemlessÓ conÞguration.
