> 11.20 | ATH Manual rejection of a network request for PDP context activation

> The V.250 ATH command may be used to deactivate all PDP contexts which are active or online on the same interface. This command should not be used to deactivate PDP contexts during the implicit PDP context deactivation procedure which is started automatically after LCP termination or by dropping the DTR line (if AT&D2 is configured). For details refer to Section 11.5.1, Automatic deactivation of PDP context during dial-up PPP.
> The ATH command may also be used to reject a network request for PDP context activation announced by the unsolicited result codes "RING: GPRS" or "+CRING: GPRS".

> Notes

> • | In contrast to GSM 07.07 it is possible to cancel a connection with ATH after a break. This is done for compatibility reasons due to the "dial-up network" drivers of Microsoft Windows.

> • | ATH is used as a standard V.250 AT command, too.

> • | If ATH is used to reject a network request for PDP context activation, then other PDP contexts on the same interface which are active or online will not be deactivated.
