Call Handover Status
This parameter offers a workaround to prevent problems during call handover into the 1900 MHz (or 1800 MHz)
band, caused by non-conforming configurations of the 1900 MHz (or 1800 MHz) GSM network.
“0“ (P) Disable workaround.
“1“ Enable workaround. This value should be selected when handover into a 1900
MHz (or 1800 MHz) GSM network fails. If required for permanent use the value
needs to be set each time the ME is restarted.
URC RING line
This parameter can be used to control the behaviour of the RING line to indicate URCs (both for idle interfaces
and, if configured by the parameter "URC/Datamode/Ringline", if link is reserved) and, if configured, the indicator
for incoming IP packets (see parameter "GPRS/RingOnIncomingData" (
<groid>
).
Parameter is local for the interface, volatile and will not be reset by
AT&F
.
“off“ URC is not indicated by RING.
“local“ (P) URC will be indicated by an activated RING line of the interface on which the
URC appears
“asc0“ URC is indicated by an activated RING0 line.
URC RING line Active Time
This parameter can be used to control how long the RING line is activated to indicate URCs (both for idle inter-
faces and, if configured by the parameter "URC/Datamode/Ringline" (
<udri>
), if link is reserved) and, if con-
figured by the parameter "GPRS/RingOnIncomingData", to indicate incoming GPRS IP data packets
(
<groid>
).
Parameter is global for all interfaces, volatile and will not be reset by
AT&F
.
“0“ RING line will be activated for a time between 4.6 and 9.2 ms.
“1“ RING line will be activated for about 100ms.
“2“ (P) RING line will be activated for about 1s.
URC Datamode RING line
This parameter specifies whether RING or BREAK is used for the signaling of URCs when the TA-TE link is
reserved (e.g. during circuit-switched data calls, fax connections, in GPRS data mode or during the execution
of an AT command).
Parameter is global for all interfaces, volatile and will not be reset by
AT&F
.
“off“ (P) URC will be indicated by BREAK
“on“ URC is indicated by an active RING line for a time which is configured by the
parameter "URC/Ringline/ActiveTime" (
<urat>
). The RING line which will be
used, can be configured by the parameter "URC/Ringline" (
<uri>
).
