•
Two additional RS-232 serial cables (to be used with the serial cable that was connected from the
PBXLink box directly to the primary server when it was integrated with the phone system). With
these three serial cables, connect one serial cable from the SMDI port in the first PBXLink box to
the data splitter unit; connect the second serial cable from the data splitter unit to the serial port on
the primary server; and connect the third serial cable from the data splitter unit to the serial port on
the secondary server.
