Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 44
<uri> URC RING Line
This parameter can be used to control the behavior 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 Default (This is a powerup default which is not stored at power down).
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.
<udri> 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,
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 URC will be indicated by BREAK. Default (This is a powerup default
which is not stored at power down)
on URC is indicated by an active RING line for a time. It is configured by
“URC/Ringline/ActiveTime” (<urat>). The RING line, which will be used,
can be configured by “URC/Ringline” (<uri>).
<urat> 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 interfaces and, if configured by
“URC/Datamode/Ringline” (<udri>), to indicate if link is reserved) and, if
configured by “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 RING line will be activated for about 1s. Default (This is a powerup
default which is not stored at power down)
Notes:
• Any changes to parameters of the Autoexec function will be saved and restored on next power-up only when
the ME is switched off via AT commands (e.g. AT+CFUN or AT^SMSO).
• Please keep in mind, that each time the ME is restarted the timers of all autoexec actions configured with
<AutoExecType>=1 and <AutoExecPeriod> will be reinitialized and restarted. As a result, an autoexec
action configured at a time later then a scheduled automatic restart would never be executed.
• Be careful using <AutoExecType>=1 with small period values and shutdown or reset AT commands, since
only little time remains to change these settings again after MC75i restart.
• If <AutoExecATC> uses AT commands containing secret data, this information may be retrieved with
AT^SCFG?. For instance, this applies if using AT+CPIN.
• Parameters "GPRS/ATS0/withAttach" (<gs0aa>) and "GPRS/RingOnIncomingData" (<groid>) are available
only for modules supporting GPRS.
• This command is not PIN protected.
• In airplane mode, not all described functions are available. For example, the test or read command is
usable, the write or execute command may not. Furthermore, only some of the listed parameters can be
changed in airplane mode. A typical example is AT^SCFG that controls different features.
