Other I-modem Features A-3

Saving Money With Analog Calls

By default, the I-modem anticipates the rare occasion that telephone

company equipment incorrectly allows a digital connection when you call

a modem or fax machine. In these situations, although the I-modem

proceeds with the call as a standard analog (fax or modem) call, the

telephone company bills the call as digital.

Digital and Analog Billing Structures

Often the billing structure for digital (“data”) calls is different than for

analog (“3.1 kHz audio”) calls. In some areas, telephone companies charge

a flat rate for analog local calls and bill digital calls by usage at a metered

rate. Although all long-distance calls are typically metered, long-distance

digital calls tend to be slightly more expensive than long-distance analog

calls.

To do this Use this setting

Prevent the I-modem from behaving like a

fax/modem over digital connections

S68.0=1

When you use this setting, and the I-modem detects an analog device over

a digital connection, it ends the call. If you check the call status

information by sending I6 , the I-modem reports:

Disconnect Reason is Analog Destination Over a Digital

Network Connection.

Forcing Analog Calls

If your calls to analog devices fail and you can’t figure out why, you can

always:

To do this Use this setting

Force analog calls (and be billed at analog

rates)
