CHAPTER 2: Introduction
2. Introduction
The FradSwitch A/S 3 Port provides easy, cost-effective access to a packet-switching
network. It also provides packet-switching capability for both X.25 and Frame
Relay.
The FradSwitch has three ports which support aggregate data rates up to
2 Mbps. Each port can be configured—through a firmware-resident set of
configuration menus that you can access with an attached terminal—to use any of
the following protocols: X.25, Frame Relay, HDLC, STM, asynchronous, or
IP/SLIP. Switching between ports is provided for X.25, Frame Relay, and
encapsulated protocols.
Depending on the model you ordered, the FradSwitch’s ports can be any of
several combinations of EIA/TIA RS-232 (ITU-T V.24) or RS-530 or ITU-T V.35 or
X.21. These physical interfaces can be DCE or DTE (user-configurable). The
“-DDS” models have a DDS interface on port 1 which is always DTE.
The FradSwitch A/S 3 Port supports a wide range of applications. For
information on configuring the FradSwitch’s firmware, refer to the
