Motorola V.34-SDC, and V.32bis, 326X V.34 manual ITU Recommendation V.35 Modem-to-Computer Interface

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.
