Telenetics 326X V.34, V.34-SDC, V.32bis Series ITU Recommendation V.35 Modem-to-Computer Interface

ITU Recommendation V.35 Modem-to-Computer Interface

Interface Pinouts

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. I fyou make such a connection, you may seriously damage the modem. Telenetics 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.
