Connection Data for Data Channel with V.35 Interface
The following sections provide information on the cables required to connect
user’s equipment to a data channel with V.35 interface in the various timing
modes.
DCE Mode
This mode is used to connect to user’s equipment with V.35 DTE interface. 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-HS2V1, is available from RAD.
