ITU Recommendation V.35 Modem-to-Computer Interface
For compatibility with DTEs operating with a V.35 interface, the 326XFAST-
SDC Series Modem supports an optional ITU Recommendation V.35 Modem-
to-Computer interface. Connection is made through the modem’s DTE port
(see Figure B-1).
NOTE: The 326XFAST-SDC Series Modem with a V.35 interface is currently
available in the U. S. A. and Canada.
Caution
The 326XFAST-SDC Series Modem, if ordered with ITU’s V.35
Recommendation, supports connection to external equipment also
operating with a V.35 electrical interface. If your DTE does not
have a V.35 interface, do not, under any circumstances, connect the
modem to a non-V.35 device. If you make such a connection, you
may seriously damage the modem. Motorola makes no guarantee
of the equipment’s integrity if you do not ensure that compatible
interfaces are used. If your DTE does not have a V.35 interface, use
an external converter cable.

NOTES:
1) The modem is configured at the factory for an EIA/TIA 232-D interface or
ITU rate V.35, and is shipped according to what you specify. Both interfaces
are not available in the same unit.
2) When operating with the V.35 interface, switch S1 must be set to the off (up)
position.
