Fax, too.

As a fax, the Modem 34336 is compatible with Group III, Class 1 and Class 2 Fax. It supports multiple modulation stan- dards and speeds for a variety of fax transmissions, including V.17 at 14.4 and 12 kbps, and 9600 and 7200 bps; V.29 at 9600 and 7200 bps; and more.

Automatic dial backup.

For leased-line applications, the Modem 34336 supports automatic dial backup. The modem monitors carrier level and signal quality and, if performance drops below selected thresholds, automatically establishes a dialup PSTN connec- tion. Automatic lookback returns the connection to the leased line when the link is restored.

Front-panel configuration.

Configure the modem using the 2 x 20 character LCD and six front-panel buttons. You can also use AT commands to control configuration parameters through the DTE interface.

Diagnostics.

Last but not least, the modem includes V.54 diagnostics to quickly isolate problems and increase uptime. Test the modem from the front panel or through the DTE interface. The modem supports Analog Loopback (Loop 3), Analog Loopback Selftest, Analog Loopback Selftest with Errors, Remote Digital Loopback (Loop 2), and Remote Digital Loopback Selftest. Use the LED display to monitor the DTE interface as well as transmit and receive on the phone line.

Technically Speaking

•In leased-line applications, the Modem 34336 monitors received carrier level and signal quality.

If performance drops below selected thresholds, the local modem automatically establishes a dial connection to the remote modem. Thanks to automatic loopback, the communication path returns to the leased line when conditions improve.

•In dialup applications, the Modem 34336 can be pro- grammed to redial the remote modem automatically. This is particularly helpful if the dialup line connection is lost.

•The automatic password protection (APP) feature gives you transparent security support by incorporating the password as part of the modem training process. You can also program the modem to call back the originator during the APP security process.

•The Modem 34336 supports Analog Loopback (Loop 3), Analog Loopback Selftest, Analog Loopback Selftest with Errors, Remote Digital Loopback (Loop 2), and Remote Digital Loopback Selftest.
