DTE1 Mode
This mode is used to connect to user’s equipment with V.36/RS-449 DCE
interface that can accept, as its external clock, the receive clock signal provided
by the
FCD-E1LC data channel.
The V.36/RS-449 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-8 ) is terminated in a 25-pin male D-type connector at the FCD-E1LC
side, and a 37-pin female connector at the user’s side. A suitable cable,
designated CBL-HS2R2, is available from RAD.
Cable wiring is given in
Table A-11 .
