PAD |
| The ZipPAD
is a packet assembly/disassembly X.25 device (PADs). The primary
functions of a PAD are to exchange information via data packet form
with a remote PAD in the X.25 packet switch network, and to convert
these data packet information to be a data character stream to the
asynchronous equipment and vice versa. PAD works with local or remote
asynchronous (by using modem) terminals and uses the synchronous
modem, such as DSU, to connect to the X.25 packet network. In addition
to mentioned above, it can be treated as concentrator or multiplexer. |
| |
| The ZipPAD
, with its "extended PAD management functions and system commands",
can be fully configured from any local or remote asynchronous terminal
through a leased or dial-up line. These enhanced functions make
your ZipPAD be easily handled and controlled. Its security is that
the supervisor is only allowed to operate or use the extended PAD
management functions and system commands. |
| |
| The ZipPAD
be easily connected to any public switching data network (PSDN)
or private packet-switching network (PPSN). The ZipPAD can be specified
to be a DTE or a DCE , and be back-to-back setting. |
| |
| The ZipPAD
provides a X.25 synchronous port or two optionally. These dual ports
work in load-sharing mode, or in backup mode, or in fixed routing
mode to improve performance and to enhance reliability.
|
| |
| The ZipPAD
provides multiple architectures that meets your business needs.
ZipPAD series, from PC's synchronous card , personal PAD to enterprise,
with variable asynchronous ports to fit into your business needs. |
