Overview
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.
