Connecting to the Line 3

Overview

The iSPAN-Serial WAN adapter can be connected as data terminal equipment (DTE) to a communication device such as a modem, data service unit (DSU), host computer, or another serial adapter. The communication device enables connection to the Public Switched Telephone Network (PSTN), a leased line, an X.25 network, or a Frame Relay network. The iSPAN- Serial WAN adapter can also be connected as data communications equipment (DCE) to another serial adapter in a back-to-back configuration.

Through its DB25 connector, the iSPAN-Serial WAN adapter can be connected to any communication device that provides a V.24, V.35, or V.11 interface. Each interface type requires a specific cable. The adapter detects the cable connected to its DB25 connector and automatically configures itself to the appropriate interface.
