DTE1 Mode
This mode is used to connect to user’s equipment with V.35 DCE interface that
can accept, as its external clock, the receive clock signal provided by the
FCD-E1LC data channel.
The V.35 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-6 )
is terminated in a 25-pin male D-type connector at the FCD-E1LC side, and a
34-pin female connector at the user’s side. A suitable cable, designated
CBL-HS2V2, is available from RAD.
Cable wiring is given in
Table A-7 .
