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-E1

data channel.

The V.35 cable coming from the user’s equipment is connected to the FCD-E1

CHANNEL connector through an adapter cable. The adapter cable (see Figure A-2)

is terminated in a 25-pin male D-type connector at the FCD-E1 side, and a 34-pin

female connector at the user’s side. A suitable cable, designated CBL-HS2/V/2, is

available from RAD.

Cable wiring is given in Table A-6.
