This command determines the number of rings before automatic answering a call. 

000

(&F)

Automatic answer mode is disabled.

001-255

Enable automatic answering after specified number of rings. 

• This command works for MT data and fax calls.
• Autoanswering of CSD data and fax calls is supported on ASC0/Mux1 only.
• If 

 is set to higher values, the calling party may hang up before the call is automatically answered.

• The correlation between 

 and 

 is important.

Example: Call setup may fail if ATS7=30 and ATS0=20.

• Setting is local to the interface. It is allowed to have different settings on different interfaces. In such cases

the interface 'wins', which is idle and uses the smallest 

 value. 

• The ATS0 write command is PIN protected.
• The command ATS0 is also used as GPRS compatibility command to answer automatically to a network

request for PDP context activation (for details see 

 for GPRS). So using ATS0=

 with n > 0, will per-

form a GPRS attach, if the ME is not already GPRS attached and if ME is configured to do so (see 

,

parameter 

). If the GPRS attach fails (e.g. the network rejects the attach request), the write com-

mand returns an error, though the new value takes effect. 

The GPRS attach will not be performed on recalling a stored user profile with 

 or on powerup, if a n > 0

setting was stored in the user profile with
