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
