Siemens MC55 AT manual Form a Gprs attach

Parameter Description

<amr>(str)(+CSCS)

Adaptive Multi Rate

This parameter can be used to control the usage of the feature "Adaptive Multi Rate" (AMR). It is possible to enable or disable this feature for all network operators, or to enable it for selected operators (max. 10). If the feature is enabled for all operators, any request to enable it for a specific operator will result in a "+CME ERROR: operation temporary not allowed".

Changes of this parameter become active with the next call.

Parameter is global for all interfaces, volatile and will not be reset by AT&F.

"enabled"(P)	AMR is used for every operator.
"disabled"	AMR is not used for any operator.
00000...999999	Enable AMR for the specified operator (in BCD or IRA format; see AT+COPS).
<csv1>(str)(+CSCS)
Call Speech Version1

This parameter can be used to query or configure the speech version 1 indication in the bearer capabilities in case of voice calls (see GSM 04.08). Speech version 2 (EFR) is always enabled; speech version 3 ( AMR) is not affected by this command.

If you try to change this parameter as long as a circuit switched call is active, the command returns the new value and "OK", but the changes will not take effect before next call setup.

Parameter is global for the ME, volatile and will not be reset by AT&F.

"0"(P)	FR and HR codecs are enabled for speech calls - full rate codec is preferred.
"1"	FR and HR codecs are enabled for speech calls - half rate codec is preferred.
"2"	Half rate codec is disabled for speech calls.
<gs0aa>(str)(+CSCS)
GPRS ATS0 with Attach

This parameter can be used to control the behaviour of ATS0.

Parameter is global for all interfaces, volatile and will not be reset by AT&F.

"on"(P)	When the ATS0=<n> (<n>>0) command is received, the MT will attempt to per-
	form a GPRS attach.
"off"	When the ATS0=<n> (<n>>0) command is received, the MT will not attempt to
	perform a GPRS attach.

<groid>(str)(+CSCS)

Ring on incoming GPRS IP data packets

This parameter can be used to control the behaviour of the RING line for incoming IP packets in GPRS online mode.

Parameter is local for the interface, volatile and will not be reset by AT&F.

"on"	If the ME is in power saving mode 7 or 8 or 9 (see AT+CFUN) and hardware
	flow control is in use (AT\Q3) and the RTS line is inactive and there are incom-
	ing IP packets for a GPRS context which is online, then the RING line will be
	activated once, for a time which is configured by the parameter "URC/Ringline/
	ActiveTime" (<urat>). The RING line to be used can be configured with the
	parameter "URC/Ringline" (<uri>).
"off"(P)	RING line is not activated for incoming IP packets.
