Making an HSI Connection
The Eiconcard S5x can connect as a DTE to devices such as Data
Service Units (DSUs) which support one of the following interfaces:
V.24, V.35, or X.21. It can also connect directly to a host computer,
or back-to-back to another Eiconcard. Each HSI port is configured
independently
Table 1 lists the most common connections supported by the HSI
port, and specifies the part number of the required Eicon Networks
cable. For information on making your own cables, see Interface
Specifications on page 14.
Table 1. Standard Interface Cables
When you make connections through a null-modem cablefor
example, to a DTE or to the HSI port on another Eiconcardone
card must be set to internal clocking, and the other to external
clocking.
Consult the documentation which came with your networking
software for more information about port configuration.
