Itu Recommendation V.35 Modem-To-Computer Interface - Motorola 326X V.34 User Manual

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.
