X.21 Data Channel
For the X.21 port, only a cable for use in the DCE mode designated CBL-HS2X1 is
available from RAD.
This mode is used to connect to user’s equipment with X.21 DTE interface. The
X.21 cable coming from the user’s equipment is connected to the FCD-E1LC
CHANNEL connector through an adapter cable. The adapter cable (see
Figure A-7 )
is terminated in a 25-pin male D-type connector at the FCD-E1LC side, and a
15-pin female connector at the user’s side.
Cable wiring is given in
Table A-9 .
