6.3. Autoswitch Provisioning

This section describes how to configure a group of timers that are configurable via S registers. These timers have significant impact on the behavior of modem and should not be changed from default settings without consultation with your CS-CDPD service provider and Sierra Wireless.

Maxidle Timer

The Maxidle Timer defines the maximum call inactivity time. If a cellular call is established and no data is transferred for this interval, the call is terminated.

Syntax:	AT+WS192=<maxidle>
Mode:	CS CDPD
Default:	45 seconds
Minimum value:	15 seconds

Autocheck Timer

The Autocheck Timer defines how often to check whether CDPD service is available. The Autocheck Timer is active only while in idle, or suspended in CS CDPD mode, i.e., no call is established.
