Command Description

The V.25ter ATS0=<n> (Automatic answer) command may be used to turn off (n=0) and on (n>0) the automatic response to a network request for a PDP context activation.

When the ATS0=<n> (<n> > 0) command is received, the MT will attempt to perform a GPRS attach if it is not yet attached and if ME is configured to do this (see AT^SCFG, parameter <gaa>). Failure will result in ERROR being returned to the TE. Subsequently, the MT will announce a network request for PDP context activation by issuing the URC RING or CRING to the TE, followed by the intermediate result code CONNECT. The MT then enters V.25ter online data state and follows the same procedure as it would after having received a AT+CGANS=1 command with no <L2P> or <cid> values specified.

ATS0=0 does not perform an automatic GPRS detach.

Parameter Description

<n>(num)(&W)(&V)

000(&F)	automatic answering is disabled
001-255	enable automatic answering on the specified ring number

Notes

•If different settings are used on each interface, and a request for PDP context activation is received, the inter- face 'wins' which is idle and uses the smallest ATS0 value.
