10.18 ATS0 Automatic response to a network request for PDP context activation
Syntax
Command Description
The V.25ter ATS0=<n> (Automatic answer) command may be used to turn off (n=0) and on (n>0) the automa tic
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 re quest 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
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.
