6.3.3V.32bis Cellular Connections Using AT Commands

The internal V.34 modems may be set up in different ways to operate over a cellular telephone network. The following are typical setups that might be used.

•Your modem supports cellular operation from 1200 to 14,400 bps.

•MNP Class 10 is not active for connections below 1200 bps.

6.3.3.1Universal Cellular Setup

Land-side modem - AT&F (factory defaults)

This allows the land side to make data connections with land based and cellular based modems without reducing maximum connection speeds. Connections over most land lines can reach 14,400 bps modem speeds between V.32bis modems, and 28,800 bps between V.34 modems. MNP 10 cellular connections occur at the highest speed the modems determine they can support for each cellular connection. If the land-side modem will only make cellular connections, we recommend setting \N2.

6.3.3.2MNP 10 V.32bis Quick Connect Cellular Only Setup

Land-side modem - AT&F\N2)M1

This forces MNP connections to all modems and MNP 10 cellular connections to all MNP 10 modems.

Additional connection speed enhancements

In addition, registers :T17 and :T26 can shorten connect times. We suggest changing these registers only after making some cellular connections with these registers set to defaults. Using them may limit the modem’s ability to connect over noisy lines.
